On the 2014-2019 Chevrolet Silverado 1500, gM's Active Fuel Management (AFM) system deactivates cylinders to improve fuel economy, but can cause premature lifter wear and failure. Symptoms include rough idle, misfires, and valve train noise. GM released updated lifters.
Install an AFM disabler device ($100-200) to keep all cylinders active. For failed lifters: replace with updated GM lifters and consider AFM delete kit ($300-500) which includes non-AFM lifters, valley cover, and plug. Complete repair with AFM delete runs $2,000-3,500 at a shop.

On the 2014-2019 Chevrolet Silverado 1500, the EcoTec3 5.3L V8 (L83, and later L84 with Dynamic Fuel Management) uses Active Fuel Management to deactivate cylinders 1, 4, 6, and 7 under light load. The AFM lifters that collapse to deactivate those cylinders are prone to sticking or mechanical failure, often during a mistimed cylinder-mode switch event. A failed lifter stops actuating its valve, producing a loud ticking/tapping noise, rough idle, a flashing check-engine light, and a single-cylinder misfire (cylinder 7 is the most commonly reported). If a lifter disintegrates it can wipe the camshaft lobe, turning a lifter job into a cam-and-lifter job. Owners on CarComplaints report this surfacing anywhere from 80,000-120,000 miles, and it is the subject of multiple GM lifter/AFM lemon-law and class-action discussions.
Diagnose with a running-compression test on the misfiring cylinder (an AFM lifter that stays below ~25 PSI regardless of solenoid command is collapsed). Repair requires replacing the failed lifter set (typically all 16) and pushrods, and replacing the camshaft if a lobe is worn. Many owners pair the repair with an AFM/DFM delete (range device or full delete kit keeping the engine in V8 mode) to prevent recurrence. Use only the correct oil and keep oil changes on schedule, as low/dirty oil accelerates failure.
On the 2014-2019 Chevrolet Silverado 1500, on the Gen V 5.3L L83 (and 6.2L L86) in the Silverado 1500, the timing chain can stretch and the VVT cam phasers/actuators can wear, causing the camshaft to drift out of correlation with the crankshaft beyond what the variable-valve-timing system can correct. This sets crank/cam correlation and VVT codes, a startup rattle (slack chain before oil pressure builds), rough idle, reduced power, and on higher-mileage trucks a risk of the chain jumping. AFM operation and extended oil-change intervals accelerate the wear. It is a more involved repair than a sensor because it requires removing the front timing cover.
Ticking or knocking that does not clear with an oil change
How to Fix
Diagnose with a scan tool — confirm correlation/VVT codes and check live cam/crank phase data; rule out a stuck VVT solenoid or low oil pressure first. The fix when the chain is stretched is replacement of the timing chain, both cam/crank sprockets (phaser), tensioner and guides, plus an oil/filter service, and addressing any AFM-related oil consumption that contributed. Keeping oil changes on a shorter interval and using the correct spec oil reduces recurrence.

On the 2010-2014 Chevrolet Silverado 1500, generation IV 5.3L Vortec engines burn an abnormal amount of oil — many owners report a quart or more every 1,000-2,000 miles. The defect is a combination of low-tension piston rings that fail to control oil, oil spray from the Active Fuel Management (AFM) system during cylinder deactivation, and a PCV path that draws oil mist into the intake. The oil fouls and prematurely wears spark plugs, causing rough idle, misfires, and a check-engine light. This was the subject of the Siqueiros v. GM class action (N.D. Cal., No. 3:16-cv-07244), which reached a final settlement in October 2025.
Excessive oil consumption (1 qt per 1,000-2,000 mi)
Low oil level warning between changes
Blue exhaust smoke on start-up/acceleration
Fouled spark plugs
Rough idle and misfires
Lifter tick
How to Fix
GM's progression of TSBs added an AFM oil-deflector/shield and revised PCV provisions and ultimately upgraded the piston rings under warranty. Verified fix is replacement of the pistons/rings (and AFM oil-pressure relief valve / valley-cover shield); many owners opt for an AFM delete with a non-AFM cam, lifters, and tune to permanently resolve it. Monitor and top off oil between changes; replace oil-fouled spark plugs. Settlement payments (~$3,380) were available to eligible owners in CA, ID, and NC who had not already received free warranty piston repairs.

On the 2014-2016 Chevrolet Silverado 1500 5.3L V8 L83, silverado 1500 trucks with the AFM-equipped 5.3L V8 are known for burning excessive oil, with many owners reporting roughly 1 quart per 1,000 miles (GM's stated acceptable rate is up to 1 quart per 2,000 miles). The consumption is attributed to oil being drawn through the PCV system and to oil spray released from the AFM pressure-relief valve in the crankcase coating the cylinder walls; over time carbon buildup sticks the low-tension piston rings, worsening the problem and fouling spark plugs. The issue is the subject of a GM 5.3L oil-consumption class-action lawsuit. (Note: most acute on earlier Gen IV engines; the EcoTec3 L83 is improved but owners still report it on early K2 trucks.)
Low oil level / low oil pressure warning between changes
Fouled or oil-coated spark plugs
Blue smoke on startup or acceleration
Cylinder misfire from fouled plug
How to Fix
GM TSBs address the PCV-path consumption by installing an updated valve cover (and updated oil pan/AFM valve with shield) so oil is not pulled into the intake. For ring-related consumption, the dealer fix is replacing the pistons and rings. Disabling AFM (range device/delete) reduces consumption if rings are not yet damaged. Owners should monitor oil level between changes and clean/replace fouled plugs.
On the 2014-2024 Chevrolet Silverado 1500 All engines with Integrated Trailer Brake Control (RPO JL1), silverado 1500 trucks built with the factory Integrated Trailer Brake Control system (RPO JL1) do not simply pass current to the trailer. The Trailer Brake Power Control Module (K133) continuously injects a low-level test pulse onto trailer brake output circuit 47, and the Chassis Control Module (K38/K38A) or Brake System Control Module (K160) reads how that pulse behaves to decide whether the trailer has electromagnetic drum-brake magnets or an electric-over-hydraulic (EOH) actuator, and to keep watching the circuit for opens, shorts and plausibility faults. GM's own Preliminary Information bulletins PIT5509F and PIT5509J identify a specific, repeatable incompatibility: certain Dexter electric-over-hydraulic actuators — identified by the serial-number prefixes TCV, TCB or CBH — were never designed to be compatible with GM's integrated trailer brake diagnostics. The failure is deceptive because the system appears healthy at first. The truck recognizes the trailer, the driver sees 'Trailer Connected' on the DIC, and the gain setting works normally on the first stop. Then, as soon as the brake pedal is applied, a 'Check Trailer Wiring' message appears in the Driver Information Center. After several more brake applications, the message escalates to 'Service Trailer Brakes,' the module latches DTC C1114, and the truck disables trailer brake output entirely for the remainder of that ignition cycle. The driver is then towing a loaded trailer with no trailer braking at all, relying only on the truck's own brakes — which is why owners typically discover it as a sudden loss of trailer brake feel partway into a trip, most often on a boat, car-hauler or heavy equipment trailer where EOH disc brakes are common. Cycling the key clears it temporarily, which sends many owners down a fruitless path of replacing the truck's trailer brake module, rewiring the 7-way, or blaming the truck, because nothing on the vehicle side ever tests bad. The tell-tale that separates this from ordinary trailer wiring corrosion is the pattern: the fault only ever appears with one particular trailer, it always takes several brake applications to set, and it always resets clean at the next key cycle.
'Check Trailer Wiring' message on the Driver Information Center after the first few brake applications with a trailer connected
Message escalates to 'Service Trailer Brakes' or 'Service Trailer Brake System' after repeated braking
Trailer brakes stop working entirely for the rest of the ignition cycle
Fault clears at the next key cycle and then repeats
Only happens with one specific trailer; other trailers tow with no message
Trailer brake gain adjustment appears to have no effect once the message appears
How to Fix
Do not start by replacing parts on the truck. GM's diagnostic path is to prove which side of the 7-way connector owns the fault. Build or borrow the magnet-based tester described in PIT5509F/PIT5509J — a Pollak heavy-duty 7-way RV plug (part 12-706) wired to 2, 4, 6 or 8 trailer brake magnets (Dexter K71-104-00 or equivalent) in parallel across the ground and brake-controller-output terminals with 12-gauge wire — plug it into the truck, and drive it. GM has also released a trailer simulator tool, P/N EL-52641, that serves the same purpose. If the DIC shows 'Trailer Connected,' the scan tool's 'Trailer Brake Type' parameter reads as expected, and no C1114 sets with the tester attached, the truck's ITBC system is functioning correctly and the fault is on the trailer. Next, read the serial number off the Dexter EOH actuator on the trailer. If the first three characters are TCV, TCB or CBH, this bulletin applies directly. The accepted repair is to install a compatibility adapter on the trailer, between the 7-way and the EOH actuator, that isolates the actuator from the truck's diagnostic test pulse. GM's later bulletin (PIT5509J) names Dexter's Electric-over-Hydraulic Compatibility Adapter, part number K58-036-00; the earlier revision (PIT5509F) referenced the Hydrastar Controller Adapter Module HBA CAM 381-7073, which does the same job. The adapter mounts on the trailer, wires inline with the actuator's brake-output and ground leads, and typically costs roughly $90-$160. A competent shop or an RV/trailer dealer can install it in about an hour; it is well within reach of a DIY owner comfortable with 12-gauge crimps and heat-shrink butt splices. After installation, clear DTC C1114, reconnect the trailer, and confirm through several progressively harder brake applications at road speed that no message returns and that trailer brake output still responds to the gain adjustment. Two things worth knowing before you chase this further: PIT5509F states that on 2019-2020 Silverado/Sierra (new body style) the CCM/BSCM does not distinguish between electromagnetic and electro-over-hydraulic brakes and will detect either as electromagnetic — that is normal and not a fault. And an EOH pump motor needs roughly a 20-30% duty cycle before it will spin at all, so a light pedal or a gain set too low can look like 'no trailer brakes' when nothing is broken; also note that with EOH brakes detected, applying the pedal at 0 mph produces no output to the pump motor, which is likewise normal. Verify gain is set per the owner's manual before condemning any hardware. Warranty note: GM states trailer-side issues are not covered under the vehicle warranty, so expect this to be a customer-pay repair even on a new truck.
On the 2007-2014 Chevrolet Silverado 1500, the original galvanized-steel brake (and fuel) lines on these trucks lack the modern nylon/PVF anti-corrosion coating, so in cold-weather/road-salt states the lines rust from the outside in and rupture. A brake-line burst causes sudden, often warning-light-free loss of brake pressure and a long/soft pedal; NHTSA logged hundreds of complaints and opened (then closed without recall) an investigation into salt-belt GM trucks. GM addressed it with a TSB and a pre-formed replacement-line kit rather than a recall.
Inspect all underbody brake and fuel lines for surface rust/flaking, especially over the rear axle and along the frame rails. Replace corroded sections with GM's pre-formed brake-line kit (TSB 13-05-22-001) or aftermarket coated/stainless lines; bleed the system afterward. Proactively replace lines as a set in salt-belt trucks before failure, and wash the underbody regularly through winter. Any soft/sinking pedal or visible fluid leak should be treated as do-not-drive.
On the 2014-2018 Chevrolet Silverado 1500, the engine-driven brake vacuum pump on 2014-2018 Silverado 1500 trucks (5.3L and 6.2L V8) can lose vacuum output over time as oil sludge and debris are trapped by the pump's oil inlet filter screen. As vacuum drops, power brake assist decreases, producing a hard brake pedal, increased pedal effort, and longer stopping distances, most noticeably at low speed (parking lots, slowing for crosswalks). GM recalled roughly 3.4 million trucks and SUVs for this condition under NHTSA campaign 19V645000 (GM recall N192268490), and NHTSA's underlying investigation was closed after the recall.
Longer stopping distances, especially at low speed
Service brake assist or ABS warning
Reduced power brake assist when maneuvering slowly
How to Fix
Under the recall, dealers reprogram the Electronic Brake Control Module (EBCM) software to better detect low vacuum and compensate via the ABS/stability system; affected owners should confirm the recall remedy has been applied via VIN at NHTSA.gov. Out-of-recall vehicles experiencing a hard pedal should have the vacuum pump tested and replaced if output is low, and the oil change interval kept current to limit sludge.
On the 2007-2019 Chevrolet Silverado 1500, p0700 is not a specific fault by itself — it is an umbrella/MIL-request code the ECM stores whenever the transmission control module (TCM) detects an internal transmission problem and asks the ECM to turn on the check-engine light. On the Silverado 1500 it almost always appears alongside more specific companion codes, and the underlying failure follows two dominant, well-documented patterns depending on the transmission. On trucks with the 6L80 six-speed automatic (2007-onward 5.3L and 6.2L V8 models), the internal TEHCM (Transmission Electro-Hydraulic Control Module — GM's combined valve body, solenoids, pressure switches, and TCM in a single pan-mounted unit) develops internal circuit-board/solenoid faults from heat and fluid degradation, throwing P0700 together with codes like P0796, P0777, P0842, or P0973 and dropping the truck into limp mode. On older/base trucks with the 4L60E four-speed (4.3L/4.8L), the same P0700 is typically triggered by a failed shift solenoid (P0753/P0758) or a faulty internal mode switch. Because P0700 is a stored 'passenger' code, a scan tool that can talk to the TCM (not just a basic reader) is required to pull the specific sub-code that identifies the actual failed component.
Transmission stuck in limp mode / limited to one gear (often 3rd or 5th)
Harsh or delayed shifts
Transmission fails to shift or slips
Torque converter clutch not locking up / shudder
No movement or won't shift out of park in severe cases
How to Fix
Do NOT replace parts off the P0700 alone. Use a bidirectional/TCM-capable scan tool to read the companion codes stored in the transmission controller and verify transmission fluid level and condition first (low or burnt DEXRON-VI fluid alone can trigger the chain). For 6L80 trucks, a failed internal TEHCM is confirmed by multiple simultaneous solenoid/pressure codes; the fix is to drop the pan and replace the TEHCM, which MUST then be programmed to the vehicle's VIN with GM calibration files before the truck will start or shift correctly (ordering the OEM unit by the last 8 VIN digits can yield a plug-and-play unit needing no fast-adapt relearn). For 4L60E trucks, replace the specific failed shift solenoid or internal mode switch identified by the sub-code. Repair the wiring/connectors to the TCM if corrosion is found. On very new 2023-2025 Silverado 1500s, P0700 paired with P0747 is a known valve-body defect covered by Safety Recall N242454440 / Special Coverage N242454441 — check the VIN with a dealer for a free repair.
On the 2014-2024 Chevrolet Silverado 1500, the Silverado 1500 uses a rack-mounted electric power steering (EPS) system, and owners across multiple model years report sudden, momentary loss of steering assist — usually at low speed — often with a 'Service Power Steering / Drive Carefully' message, a clicking or notchy feel, and warning lights. On the 2014-2015 trucks GM recalled vehicles for a software condition where assist could drop out and then return abruptly (reprogram of the steering control module). For 2020-2024 trucks, NHTSA's Office of Defects Investigation opened an investigation after a high volume of complaints of sudden power-steering failure; many of these resolve with a full steering gear (EPS rack) replacement rather than a software flash. Loss of assist sharply increases steering effort and crash risk, especially during parking-speed maneuvers.
Steering suddenly gets very heavy / loss of power assist
'Service Power Steering' or 'Power Steering Reduced, Drive Carefully' message
Steering assist drops out then snaps back, especially at low speed
Clicking, clunking, or notchy feel from the steering
Steering or stability warning lights illuminated
How to Fix
First have the steering control module software updated to the latest calibration and scan for steering DTCs / check for any open recall by VIN at a GM dealer (the 2014-2015 fix was a module reprogram). If assist loss persists or the rack is found internally faulty, the repair is replacement of the electric power steering gear (rack) assembly with recalibration. Document the failures and report them to NHTSA, as the 2020-2024 trucks are under active investigation and may become eligible for a recall remedy.
On the 2014-2020 Chevrolet Silverado 1500, the A/C compressor can fail prematurely, especially on trucks in hot climates or with heavy A/C use. Internal compressor failure can contaminate the entire A/C system with debris, requiring extensive repairs.
Common Symptoms
A/C blows warm air
Loud noise when A/C engages
A/C clutch won't engage
Refrigerant leak at compressor

High Confidence780 owner reportsLast reported by owners Feb 2024Reviewed Feb 2026
On the 2014-2022 Chevrolet Silverado 1500, a widely reported Silverado 1500 complaint is a sudden cascade of dash messages — 'StabiliTrak disabled,' then 'Service StabiliTrak,' 'Service Traction Control,' and finally 'Engine Power Reduced' — sometimes with a stumble or stall and limited throttle response. The most common root causes are a faulty accelerator pedal position (APP) sensor or throttle body (electronic throttle), but it is also frequently traced to poor/corroded ground connections and chafed wiring under the driver's door sill or at the underseat/main harness connector. Because it can drop the truck into reduced-power limp mode at speed, owners treat it as urgent.
'Service StabiliTrak' and 'Service Traction Control' messages
'Engine Power Reduced' / limp mode
Throttle becomes unresponsive or truck stalls
Multiple ABS/traction/stability lights at once
Symptoms come and go (intermittent)
How to Fix
Scan for stored codes (commonly P2138 and related APP/throttle codes) and read live throttle/pedal data. Start by inspecting and cleaning the body grounds under the driver's door and the main harness connector (a known fix), then test/replace the APP sensor or throttle body as indicated. Apply any GM throttle-body or PCM software updates. Confirm the actual failed component before replacing the throttle body, as wiring/ground faults mimic sensor failure.
What you need to diagnose it
The repair instructions explicitly call for reading stored codes.

On the 2014-2019 Chevrolet Silverado 1500, trucks with the column shifter throw a persistent 'Shift to Park' message on the driver information center even though the lever is fully in Park. The cause is a small microswitch/park-confirmation contact behind the lower steering-column trim (to the right of the column) that fails or falls out of adjustment, so the BCM never confirms Park. This blocks the key/ignition from fully powering down, prevents the doors from locking, and can drain the battery overnight. A broken internal plastic detent in the shift lever can produce the same fault.
'Shift to Park' stays on the dash after shifting to Park
doors won't lock and truck won't fully power down
battery drain / dead battery overnight
message clears intermittently after wiggling the shifter

How to Fix
Access the microswitch behind the lower steering-column shroud; clean, re-seat, or replace it. If the internal shifter detent is broken, replace the column shift-lever assembly (no steering wheel/airbag removal required). Confirm the transmission range/park signal with a scan tool before parts replacement to avoid unnecessarily swapping the whole column.
On the 2014-2018 Chevrolet Silverado 1500, front heated seats (RPO KB6) on K2XX Silverado 1500 trucks commonly stop working, often both seats around the same time and at relatively low mileage. GM addressed diagnosis in service material (PIT5434C) for the front heated seats; owners and technicians find broken heating-element grids in the cushion/back and, frequently, browned or burnt connector pins at the seat-heater connector. Because the cushion and back heater elements and the connector can all be implicated, repair quotes are sometimes high if the whole element pad is replaced. It is a comfort/convenience failure rather than a safety defect.
Burnt or discolored pins at the seat-heater connector
Heated-seat indicator turns on but no heat
Intermittent heating on one seat
How to Fix
Diagnose per GM PIT5434C: inspect the seat-heater connector for burnt/browned pins (repair the connector/terminals if found) and ohm-test the cushion and back heater element grids; replace the failed heating element pad(s) as needed. Checking and repairing the connector first can avoid an unnecessary full element replacement. Verify the heated-seat module/switch is commanding power before condemning the elements.

On the 2007-2018 Chevrolet Silverado 1500, the cable-type power window regulators are a recurring weak point. The plastic cable guides/spools crack or the cable frays and jumps its track, so the window drops into the door, closes crooked, or the motor spins/clicks without moving the glass. Many owners report replacing regulators multiple times per door. Worn window motors and broken wires in the door-jamb harness produce similar no-move symptoms.
Replace the window regulator-with-motor assembly (e.g., Dorman 741-442 front driver side for 2007-2013; OE-fix designs add reinforced cable guides). Inspect the door-jamb wiring harness for broken conductors and test the master switch before assuming the regulator. Lubricate the run channels to reduce load on the new regulator.

On the 2014-2022 Chevrolet Silverado 1500, the integrated door-lock actuators in K2XX/T1 Silverado 1500 trucks are a high-frequency failure. The small motor and plastic gears inside the actuator wear out, so the power lock buzzes, grinds, or clicks, operates intermittently or cycles rapidly, or stops working entirely on one or more doors. Owners frequently report a domino effect — replacing one actuator, then having another door fail within weeks — and some failures are temperature-dependent (works in heat, dead in cold). On Silverados the lock actuator is integrated into the door latch assembly, so the whole latch is often replaced.
Buzzing, grinding, or rapid clicking from inside the door when locking
Power lock works intermittently on one door
Lock works on warm days but not cold (or vice versa)
Door won't lock or unlock with the fob or switch
Multiple doors failing over a short period
How to Fix
Confirm the failed door(s) and that fuses/relays and the body control module are good, then replace the affected door lock actuator / latch assembly (the actuator is built into the latch on these trucks). It requires removing the interior door panel and water shield. Because failures cluster, many owners proactively replace adjacent actuators. Use a quality OE-equivalent latch/actuator to avoid early repeat failure.
On the 2007-2024 Chevrolet Silverado 1500, gM's small-block V8s (Gen III/IV LS and Gen V LT) in the Silverado 1500 are notorious for snapping exhaust manifold bolts. The steel bolts and the aluminum cylinder heads expand and contract at different rates through countless heat cycles, fatiguing the bolts until the heads snap off — usually the front and rear corner bolts. The resulting manifold-to-head gasket leak produces a loud 'exhaust tick' (often mistaken for a lifter) that is loudest on cold start, and the leak draws outside air past the upstream O2 sensor, frequently setting a false P0420 catalyst-efficiency code even with a good converter. Left alone it can also burn nearby wiring and worsen the leak.
Ticking/tapping exhaust noise, loudest on cold start
Tick that quiets as the engine warms up
Exhaust/sulfur smell near the engine
P0420 catalyst-efficiency code with an otherwise good converter
Soot or carbon tracks at the exhaust manifold flange
How to Fix
Inspect the manifold flanges for soot/leak tracks and the corner bolts for breakage. Repair is to extract the broken bolt shanks (often requires drilling/extractor or a slide-hammer style broken-bolt kit), replace the manifold gaskets, and reinstall with upgraded fasteners — ARP 134-1102 header bolts on Gen III/IV LS (4.8/5.3/6.0) or ARP 134-1104 on Gen V LT (5.3 L83 / 6.2 L86) — torqued in sequence with anti-seize. Re-evaluate any P0420 after the leak is sealed before condemning the catalytic converter or O2 sensors.

On the 2007-2024 Chevrolet Silverado 1500, the full-size Silverado 1500 is one of the most frequently targeted vehicles in the U.S. for catalytic converter theft. Its high ground clearance and underbody-mounted, easily reached converters let thieves cut them out in seconds, often in broad daylight, and lifted trucks are even easier to get under. Owners discover the theft by a sudden extremely loud, raspy exhaust on startup, a check-engine light, and reduced performance. Replacement of OEM converters plus the O2 sensors and pipe is expensive, and repeat thefts are common because nothing about the factory design deters re-targeting. This is a high-search, high-demand ownership problem rather than a manufacturing defect, but it is specific and well documented for this model.
Extremely loud, deep roaring exhaust noise on startup
Visible missing converter / cut pipe under the truck
Check engine light (catalyst efficiency) after the theft
Reduced power and rough running
Strong exhaust smell entering the cabin
How to Fix
Replace the stolen converter(s) — OEM or CARB-compliant aftermarket — along with any damaged O2 sensors and exhaust pipe sections, then add theft deterrents: a welded catalytic-converter shield/cage (e.g., CatClamp / model-specific plate), etched/engraved converter ID, and parking in lit or secured areas. A tilt/vibration alarm can also help. Insurance comprehensive coverage often applies. Note: a separate 2019 emissions recall addressed an ECM that could fail to illuminate the malfunction-indicator light on a converter fault — unrelated to theft but worth checking by VIN.
On the 2014-2018 Chevrolet Silverado 1500, the factory air-conditioning condenser on 2014-2018 Silverado 1500 trucks is prone to cracking and refrigerant leakage, frequently at the spot welds on the sides of the condenser where vibration concentrates stress (revised replacement units add welds to spread the load). The result is a slow R134a leak and the A/C gradually blowing warm/hot air, often with under 50,000-70,000 miles. The problem is heavily documented on CarComplaints (13 condenser-cracked complaints on the 2016, 26 A/C-blowing-hot complaints on the 2015) and led to a GM A/C class-action that survived dismissal. Owners report parts backorders and limited 3-year/36k warranty coverage adding to frustration.
Common Symptoms
A/C blows warm or hot air
Gradual loss of cooling over weeks
Refrigerant low / leak detected at condenser
Oily residue or dye trace at condenser welds
A/C works intermittently then quits
How to Fix
Confirm the leak (UV dye / electronic sniffer at the condenser welds), then replace the condenser with the revised-design unit, evacuate and recharge the system with the correct R134a charge, and replace the receiver/drier and any contaminated orifice/expansion components. Out-of-warranty owners often use a quality aftermarket condenser to control cost.

V8 (5.3L L83 / 6.2L L86) trucks ONLY - the 4.3L V6 uses a different condenser (see separate entry). GM has superseded this condenser repeatedly as the design was revised: 23141861 -> 84211191 -> 84243590 -> 84537373 -> ...
On the 2014-2015 Chevrolet Silverado 1500, early K2XX Silverado 1500 trucks have a documented A/C failure separate from the well-known condenser leak: the high-side discharge hose/tube running from the compressor to the condenser cracks at the sharp metal bend near the receiver/drier, dumping the entire refrigerant charge so the A/C blows warm. GM acknowledged a design flaw in the rigid metal section of this line in a technical service bulletin (PIT5331), redesigned the tube for 2016, and instructs technicians to replace the line with the updated part and add a support bracket to limit flex. Out-of-warranty owners pay for the repair, and an unsupported replacement can re-crack.
Loss of refrigerant with no obvious external cause
Oily/dye residue at the high-side line near the drier
Refrigerant leak found at the metal bend of the compressor-to-condenser hose
A/C cools again only briefly after a recharge
How to Fix
Recover the system, replace the high-side discharge line with the updated GM tube, and install the support bracket per TSB PIT5331 to minimize movement/flex; replace the receiver/drier and any damaged components, evacuate, and recharge to spec. Confirm whether the failure is the discharge line versus the separately-known condenser leak, as both exist on these trucks. Pressure/dye test after repair to confirm the leak is sealed.
On the 2014-2020 Chevrolet Silverado 1500, the rear axle develops a speed-dependent whine or howl that rises and falls with vehicle speed — the hallmark of a worn pinion (or carrier) bearing and/or a wearing ring-and-pinion. As the pinion bearing degrades it often damages the pinion seal, leaking gear oil from the front of the differential, which accelerates the wear. Owners commonly report the noise appearing after higher-mileage use or towing.
gear oil leak at the front of the differential (pinion seal)
noise worse under load or towing
clunk on acceleration/deceleration in advanced cases
How to Fix
Confirm the source by checking pinion/yoke play and inspecting for a gear-oil leak at the pinion seal and axle seals. Repair requires replacing the pinion and/or carrier bearings and pinion seal and correctly setting bearing preload and gear pattern (special tools required — not a basic DIY). Severe cases need a ring-and-pinion set. Refill with correct spec gear oil and friction modifier for limited-slip axles.

On the 2014-2021 Chevrolet Silverado 1500, the aluminum driveshaft on Silverados can develop vibration from worn U-joints or an out-of-balance condition. Additionally, the slip yoke can cause a clunk during shifts or when going from acceleration to deceleration due to worn splines or dry conditions.
Common Symptoms
Vibration at 60-75 mph
Clunk when shifting into drive/reverse
Thud during acceleration/deceleration transition
Visible rust on U-joint caps
Play in driveshaft when grabbed
How to Fix
For vibration: Check U-joints for play and replace if worn. Have driveshaft balanced ($50-100). For slip yoke clunk: Apply GM slip yoke lubricant or Lubriplate 105 to the splines. If clunk persists, the slip yoke may need replacement ($200-400). TSB 14-04-21-001 addresses this issue.

On the 2007-2019 Chevrolet Silverado 1500, the center high-mount stop lamp (third brake light / cargo lamp) gasket dries out, cracks, and lets rainwater and car-wash water into the cab. Because the water runs down behind the interior trim and the carpet has a rubber backing, owners often don't see it until the rear floor is soaked, a musty smell develops, or electronic modules mounted under the rear seat corrode. It is one of the most common water-intrusion sources on these trucks and is frequently misdiagnosed as a window or door leak.
water trickling down the inside of the rear window
musty or mildew odor
corroded under-seat modules or connectors
water stains on the rear headliner
How to Fix
Remove the CHMSL, clean the mating surface, and reseal with butyl ribbon or windshield-grade urethane/silicone (or fabricate an EPDM gasket). Inspect and dry the rear floor and any under-seat modules for corrosion. A quality aftermarket lens/gasket or OEM assembly plus proper sealing typically ends the leak; total DIY cost is under $30 in sealant.
On the 2007-2022 Chevrolet Silverado 1500, on sunroof-equipped Silverados the four corner sunroof drain tubes clog with debris, so rainwater that normally drains overflows the sunroof tray and leaks onto the headliner, A-pillars, seats, and floor. Owners report wet carpet, dripping headliner, and water sloshing sounds. A cracked sunroof frame rail is a separate, more expensive cause of the same leak. It is a classic misdiagnosed 'unknown water leak.'
Clear the corner drain tubes with low-pressure compressed air (~50 psi) or a soft trimmer line, and confirm water flows out the tube exits under the truck. Distinguish a clogged drain from a failed sunroof seal or a cracked frame rail — a cracked rail requires replacing the sunroof frame assembly. Dry the headliner and floor to prevent mold.
On the 2014-2018 Chevrolet Silverado 1500, the adhesive bead sealing the clear lens to the headlamp housing deteriorates (and factory vent tubes can clog), letting moisture accumulate inside the headlight. Owners see fogging, water droplets, or standing water in the housing; once heavily contaminated the lens never fully clears, and trapped moisture can shorten LED/DRL and bulb life. It is a widely reported cosmetic-and-reliability annoyance across multiple model years.
Remove the assembly, dry it thoroughly (low heat / hairdryer), verify the vent tubes are open, and reseal the lens-to-housing joint with butyl-rubber caulk (preferred over silicone, which cracks with thermal cycling). Severely water-stained or electrically damaged units should be replaced with a new assembly that has a reinforced factory seal.
On the 2014-2019 Chevrolet Silverado 1500, k2XX-generation Silverado 1500 owners report the factory clear coat and paint peeling and flaking off in sheets, most often on the roof, hood, A-pillars, the corners of rear-door windows, and lower door edges. White colors (Summit White, Pearl White, and the tri-coat whites) are reported as the worst affected. The accepted cause is poor adhesion between the e-coat/primer and the color/clear layers, so the paint delaminates with no impact or environmental trigger. A class-action lawsuit was filed covering 2015-2019 Chevrolet/GMC full-size trucks and SUVs. GM provides no separate paint warranty beyond the standard corrosion terms, so most owners face out-of-warranty refinishing, with GM sometimes offering only partial goodwill assistance.
Clear coat bubbling, lifting, or peeling off in sheets
Paint flaking on the roof, hood, or above the windshield
Peeling at A-pillars, rear-door window corners, and lower door edges
Bare primer or metal exposed under peeled areas
Most common on white-painted trucks
How to Fix
No recall exists; repair is a body-shop refinish of the affected panels (strip to substrate, re-prime, re-base, re-clear). Costs scale with how many panels are involved — a single panel respray is a few hundred dollars while a roof + hood + pillars job runs into the low thousands. Owners are advised to open a goodwill/customer-assistance case with GM (some receive partial reimbursement) and to keep documentation in case of class-action eligibility. Correcting it early on one panel prevents spread of the lifted clear coat.
On the 2007-2024 Chevrolet Silverado 1500, the mechanical (belt-driven) water pump on the LS/LT V8 Silverado 1500 is a common wear-out item. The internal shaft seal fails and coolant seeps from the pump's weep hole, often appearing as orange/Dex-Cool residue or a puddle at the front-center of the truck; the weep-hole drip can be hard to spot until the bearing also starts to whine. Owners report leaks commonly at roughly 60,000-100,000 miles. If ignored it leads to coolant loss and overheating. Some apparent water-pump leaks turn out to be a failed gasket rather than the pump itself, so confirmation matters.
Orange/Dex-Cool coolant puddle at front-center of the truck
Coolant seeping from the water-pump weep hole
Low coolant warnings or repeated topping off
Whining or grinding from the pump bearing
Engine running hotter than normal / overheating
How to Fix
Pressure-test the cooling system and confirm the leak is from the pump weep hole / shaft seal versus a gasket or hose. Replace the water pump (and gasket), refill with the correct GM Dex-Cool spec coolant, and bleed the system. Inspect the belt and tensioner while accessing the pump. Address any low-coolant overheating before it damages head gaskets.

On the 2014-2018 Chevrolet Silverado 1500, a steering wheel shake or vibration at highway speeds (60-80 mph) is common on K2 generation Silverados. This is often caused by tire balance issues, but can also be related to worn suspension components or warped brake rotors.
Start with tire balance and rotation. If shake persists, inspect tie rod ends, hub assemblies, and ball joints. Check brake rotors for warping. Some owners have had success with road force balancing. Alignment should be checked.

On the 2007-2014 Chevrolet Silverado 1500, gMT900-generation Silverado 1500 trucks (and platform-mates Tahoe/Suburban/Avalanche/Sierra/Yukon/Escalade) are widely reported to develop long cracks and splits across the top of the dashboard pad, typically radiating from the passenger airbag seam, defroster vents, and the corners near the windshield. GM moved to a large one-piece molded dash for these years with no relief joints, and the plastic dries out and loses plasticizer under windshield heat and UV exposure, causing the surface to fracture. Owners commonly see it appear between 4 and 8 years of age, worse in hot/sunny climates. A class-action suit was filed and dismissed in 2019, and GM treats it as a cosmetic, non-warranty item, so owners pay out of pocket. Beyond appearance, owners raise concern about cracked plastic over the passenger airbag becoming projectiles or affecting deployment, though that has not been the subject of a recall.
Long cracks or splits across the top of the dashboard near the windshield
Cracks radiating from the passenger airbag seam or defroster vents
Pieces of dash plastic lifting or curling at the edges
Worsening rapidly after summer heat or in sunny climates
How to Fix
There is no recall or warranty coverage. Common remedies are: install a molded ABS/poly dash cap (overlay) bonded over the cracked pad, replace the full dashboard pad assembly, or fit a carpeted/molded dash cover. Dealers will not warranty it as it is classified cosmetic. To slow it on an intact dash, use a windshield sun shade and a UV-protectant (e.g., 303 Aerospace Protectant). Verify any airbag-cover integrity if the crack runs over the passenger airbag door.
