A small number of 2019 Chevrolet Trax vehicles left the factory with the Sensing Diagnostic Module (SDM) - the module that decides when the air bags fire - still set to "manufacturing mode" instead of being switched to its normal operating mode. On an affected Trax, the air bags may not deploy at all in a crash. NHTSA lists 12 vehicles for the entire campaign, which also covers the 2019 Buick Encore, Chevrolet Spark and Chevrolet Traverse; that figure is campaign-wide and is not a count for the Trax specifically. GM's internal number for this recall is 18365.

Common Symptoms

  • Air bags may fail to deploy in a crash

How to Fix

The fix is free at any Chevrolet dealer: the dealer reprograms the SDM to the correct operating mode. Owner notification began November 6, 2018. Because so few vehicles are involved, the only reliable way to know if your Trax is one of them is to run your 17-digit VIN at nhtsa.gov/recalls, or call Chevrolet customer service at 1-800-222-1020 and reference recall 18365.

Some 2024-2025 Trax owners have reported forward collision warnings triggering unexpectedly, emergency braking intervening without an obvious obstacle, or driver-assistance warnings appearing intermittently. These complaints are significant because they can startle the driver or create a rear-impact risk if the vehicle brakes unexpectedly. Reports point to camera calibration, sensor visibility, or software logic issues rather than a single mechanical failure.

Common Symptoms

  • forward collision warning with no vehicle ahead
  • automatic emergency braking activates unexpectedly
  • driver assistance unavailable message
  • intermittent lane/ADAS warnings
  • warning chimes and dash alerts

How to Fix

Scan all ADAS modules for stored faults and verify windshield camera alignment/calibration status, especially after windshield replacement or front-end impact. Dealers typically inspect for obstruction, update software if available, and perform static or dynamic calibration of the forward camera. If warnings persist, the camera or related module may need replacement after confirming power, ground, and network integrity.

Multiple owners have reported the rearview camera failing to display when shifting into reverse, showing a blank/blue/black screen, or appearing only after a long delay. This issue is documented in owner complaints and overlaps with infotainment/display faults, but the safety impact is distinct because the camera is federally required equipment. In some cases the problem is intermittent, making it difficult to reproduce at the dealer.

Common Symptoms

  • no rear camera image in reverse
  • blue screen when backing up
  • black screen when shifting into reverse
  • camera image appears after several seconds
  • guidelines missing or frozen

How to Fix

Check for related GM service bulletins, software updates, and camera/radio module faults. Diagnosis should include verifying camera power/ground, coax or video signal integrity, and whether the issue is isolated to the camera or part of a broader infotainment dropout. If software updates do not resolve it, dealers may replace the camera or radio/display components depending on test results.

GM issued urgent dealer message DCS6982 on August 14, 2024 covering 2024 vehicles with the 1.2L gasoline engine - Chevrolet Trax and Trailblazer, Buick Encore GX and Envista. The engine control module may fail to properly control ignition timing following certain Auto Engine Stop/Start restart events. When that happens the malfunction indicator lamp comes on and the engine runs rough or audibly knocks; GM's own bulletin warns that continuing to drive with the knock present can cause engine damage. The matching service bulletin, 24-NA-064, directs technicians to reprogram the ECM when the MIL is set with DTC P0324 (knock control system error) and/or P0116 (engine coolant temperature sensor performance). Because detonation on a small-displacement turbo three is exactly the loading that hurts rod bearings, this is worth chasing promptly rather than living with.

This issue also affects: Cadillac CT6, Chevrolet Cobalt

Common Symptoms

  • Check engine light after an Auto Stop/Start restart
  • Audible engine knock or detonation rattle
  • Rough running after the engine auto-restarts
  • Hesitation pulling away from a stop

How to Fix

Free remedy - the dealer reprograms the Engine Control Module with updated calibration; no parts are required. Reference GM message DCS6982 and bulletin 24-NA-064 when booking. If the knock persists after the reflash, insist on a borescope and an oil-analysis/bearing inspection rather than accepting 'normal three-cylinder noise'. In the interim you can reduce exposure by switching Auto Stop/Start off at each start and running top-tier 87-octane or better fuel.

Unlike the old 1.4L turbo, the 1.2L three-cylinder in the 2024+ Trax drives its camshafts with a rubber timing belt that runs submerged in engine oil. GM acknowledges the design's shedding behavior in preliminary information bulletin PIP5938, which tells technicians that a quantity of debris found in the engine oil of these engines is a normal wear-in characteristic of the wet belt and is not by itself cause for engine replacement. The concern for owners is what that debris does over time: shed belt material collects in the sump, can partially block the oil pickup screen and the small lubrication passages that feed the main and rod bearings, and is a leading suspected contributor to the low-mileage rod bearing failures now the subject of a class action. Extended oil-change intervals, low oil level, or cheap non-dexos oil accelerate belt degradation dramatically.

Common Symptoms

  • Black rubber particles or sludgy debris in the drain oil or oil filter
  • Oil level dropping between changes
  • Low oil pressure warning
  • Bearing knock developing after an extended oil change interval
  • Timing/cam correlation faults in later stages

How to Fix

There is no recall and no revised belt part number published. Practical protection is maintenance discipline: change the oil and filter every 5,000 miles with dexos1 Gen 3 0W-20 regardless of what the oil-life monitor says, never let the level fall below the dipstick's lower mark, and ask the shop to cut open or inspect the old filter for black rubber particles. If the filter or drain pan shows significant rubber debris, or the engine has ever run low on oil, have the oil pan dropped and the pickup screen inspected and cleaned before bearing damage occurs - that is far cheaper than the engine. Wet-belt replacement is a full front-of-engine job (pan and cover off) and runs well into four figures if a belt is ever found deteriorated.

GM PIP5947C addresses North American 2024 Trax 1.2L LIH vehicles below 2,000 miles with excess oil consumption, blue exhaust smoke or idle surge. It identifies an internal camshaft-cover failure as the cause.

This issue also affects: Buick LeSabre, Buick Park Avenue, Buick Cascada

Common Symptoms

  • Excessive oil consumption
  • Blue exhaust smoke
  • Idle surge or possible oil-fouling misfire

How to Fix

A technician should confirm excessive oil in every cylinder before applying the bulletin's camshaft-cover replacement branch. After a safe post-repair road test, set and mark the oil level and verify consumption over 100 miles. Persistent consumption requires further diagnosis. Check VIN-specific powertrain coverage; replacement is not automatic from a whistle, oil-cap suction or a code. Maintain the correct oil level without overfilling.

GM preliminary information PIP5495G covers 2015–2019 U.S. Trax with the 1.4L turbo (LUV/LUJ) setting P0299 or P0234, and was issued because many returned turbochargers had no fault found. It lists wastegate-related conditions that are repaired without replacing the turbo — a broken wastegate solenoid port, bent actuator port, deposit-obstructed solenoid or hoses, or a missing actuator clip — and conditions that do warrant turbo replacement, such as a disconnected wastegate lever arm or pin, or a seized wastegate valve/linkage.

This issue also affects: Buick Cascada, Buick Encore GX, Buick Encore

Common Symptoms

  • Check engine light with P0299 (underboost) or P0234 (overboost)
  • Reduced power and sluggish acceleration

How to Fix

Follow PIP5495G or current GM service information for the exact Trax engine and market. Diagnose charge-air, induction, control-line and wastegate faults before replacing the turbo. The bulletin permits separate solenoid, actuator, clip or bypass-valve repair for specified conditions. Complete turbo replacement requires an identified qualifying failure or the prescribed professional boost-control test; normal port cracks are not a replacement indication.

The 1.4L turbocharged engine burns oil at an excessive rate, often consuming a quart every 1,000-2,000 miles. The issue is attributed to piston ring design and PCV system routing. GM considers up to 1 quart per 2,000 miles "normal" but many owners find this unacceptable.

This issue also affects: Buick Envision, Chevrolet Equinox, Cadillac XT4

Common Symptoms

  • Low oil level between changes
  • Blue smoke on startup
  • Oil smell from exhaust
  • Low oil pressure warning

How to Fix

Monitor oil level between changes and top off as needed. Replace the PCV valve and inspect the intake manifold for oil buildup. For severe consumption, an engine teardown to replace piston rings and valve stem seals may be necessary. Use full synthetic 5W-30 oil as specified.

Software in the Virtual Cockpit Unit Module (VCU) that drives the digital instrument panel can leave the cluster completely blank at startup or drop it out while driving. With the cluster dark the driver loses speedometer, fuel level, and every telltale and warning lamp. GM recalled the 2024 Chevrolet Trax along with the 2024 Buick Encore GX and Envista on November 6, 2023 under NHTSA campaign 23V744000 (GM number A232424320), with owner letters going out December 22, 2023. This is separate from the center-stack infotainment freezing complaints - it is the driver's cluster display, and it is by far the most-reported electrical failure on the 2024 Trax, with NHTSA complaints averaging around 2,300 miles at the time of failure. Some owners report the blackout continuing or the cluster failing outright after the software remedy was applied.

Common Symptoms

  • Digital instrument cluster completely black at startup
  • Cluster goes blank while driving
  • No speedometer, fuel gauge or warning lights
  • Cluster reboots repeatedly
  • Loss of telltales for ABS, airbag and charging system

How to Fix

Free recall remedy: the dealer reflashes the VCU software, or the fix arrives as an over-the-air update - no charge, and no parts needed. Check your VIN at nhtsa.gov/recalls to confirm whether 23V744000 was already performed. If the cluster still blacks out after the software update, the module itself has failed and must be replaced; that is a warranty claim inside 3 years/36,000 miles and roughly $600-$900 out of pocket beyond it. Do not drive with a dark cluster - you have no speedometer and no warning lamps.

A number of owners have reported dead batteries, slow cranking, or complete no-start conditions after the vehicle sits overnight or for a few days. On new vehicles this often traces to software modules not going to sleep properly, telematics/infotainment wake-up issues, or a weak original battery rather than a traditional charging-system failure. The problem tends to appear early in ownership and can be intermittent.

This issue also affects: Chevrolet Bolt EV, Chevrolet Suburban, Cadillac Lyriq

Common Symptoms

  • dead battery after sitting
  • slow crank
  • click no-start
  • multiple warning lights on startup
  • remote start inoperative
  • infotainment resets after jump-start

How to Fix

Load-test the battery, verify charging voltage, and perform a parasitic draw test after all modules should be asleep. Dealers may update module software, inspect for modules staying awake on the network, and replace the battery if it fails testing. Repeated jump-starting without root-cause diagnosis can mask the actual draw problem.

What you need to diagnose it

The fix here starts with a test, not a part — which repair you need depends on what the test finds.At least one code uses a manufacturer-specific format. No scanner recommendation is shown because family-level coverage cannot prove it can read that code.

Owners of the redesigned 2024-2025 Trax have reported the center infotainment display freezing, going black, losing touch response, or repeatedly rebooting. Because HVAC controls, backup camera display, audio, and vehicle settings are integrated into the screen, the failure is more than a convenience issue. GM issued service guidance addressing intermittent blank or inoperative radio/display behavior on vehicles using the newer infotainment architecture.

Common Symptoms

  • center screen goes black
  • touchscreen stops responding
  • radio reboots while driving
  • backup camera image unavailable
  • HVAC or audio controls inaccessible through screen
  • Apple CarPlay or Android Auto disconnects

How to Fix

Confirm battery voltage and check for software updates or radio module calibrations before replacing hardware. Dealers typically reprogram the radio/HMI modules first; if the concern persists, diagnosis focuses on display, radio, or communication faults on the infotainment network. If the backup camera image is also lost, document that separately because it can elevate the safety significance.

After the instrument cluster, flickering exterior lighting is the single most-reported electrical complaint on the 2024 Trax. Two related behaviours show up in NHTSA complaints: the daytime running lights and low beams flicker or blink on and off at idle and while driving, and with the switch in AUTO the ambient light sensor mis-reads conditions so the headlamps snap on in bright sun and cycle on-and-off every time the car passes under a tree line, which reads to oncoming drivers as deliberate flashing. GM addresses the behaviour in service bulletin 24-NA-001 (headlamp/DRL/taillight flashing) and preliminary bulletin PIC6530 (headlamp and DRL flashing in shaded areas), which is confirmation the pattern is real rather than a handful of one-off modules. This is a lighting-module and body-control-module software concern, not the LED assemblies themselves in most cases.

Common Symptoms

  • Headlights or daytime running lights flickering or blinking
  • Auto headlamps turning on in bright sunlight
  • Headlights cycling on and off under tree shade
  • Taillights flashing intermittently
  • Other drivers flashing back thinking they are being signalled

How to Fix

The primary fix is a free software update - the dealer reprograms the body control module and lighting control modules per bulletin 24-NA-001 / PIC6530, covered by warranty. If flicker survives the reflash, the shop should check the headlamp connector and the chassis grounds for the front lighting circuit (GM's general procedure 10-08-45-001H covers conductive-fastener ground repairs); a corroded ground or a loose connector produces the same symptom. Only after those does the LED headlamp assembly itself get replaced, which is expensive - roughly $400-$700 per side. A persistently flickering DRL is a citable equipment defect in some states, so get it documented.

The 2024+ Trax uses a compact HVAC case with electric actuators for temperature blend, and the temperature control can stick so that the cabin no longer follows the setpoint - the vents blow hot with the dial on cold, or refuse to warm up, often on one side only. GM covers the correction in service bulletin 24-NA-033 (HVAC temperature control switch sticking). A separate but related pattern seen on early cars is A/C going warm within the first 12-18 months from a refrigerant leak that traces to the evaporator inside the dash - the expensive one, since the whole instrument panel has to come out. Bulletin 23-NA-198 additionally documents HVAC cooling behaviour during remote start, which explains some 'A/C doesn't work on remote start' reports that are actually normal operation.

Common Symptoms

  • Temperature dial has no effect; air stays hot or stays cold
  • One side of the cabin blows a different temperature than the other
  • A/C gradually blows warm over the first year or two
  • Clicking or ticking from behind the dash when adjusting temperature
  • No cooling during remote start

How to Fix

For a stuck temperature setting, the dealer follows 24-NA-033 - the control head/switch is corrected or replaced and the blend actuator is recalibrated; warranty covers it inside 3 years/36,000 miles, otherwise roughly $250-$550. If the system is blowing warm on both sides, have the refrigerant charge measured and UV dye added before anything is replaced: an undercharge points to a leak, and if the dye shows at the evaporator drain the evaporator core is the source and replacement runs $1,200-$1,800 because of the dash-out labor. Get the leak diagnosis recorded before the bumper-to-bumper warranty expires.

Owners of the current-generation Trax have reported front brake squeal, scraping, or grinding noises at surprisingly low mileage, sometimes accompanied by rotor scoring or vibration. While some brake noise can be normal, repeated complaints at low mileage suggest pad material, hardware fitment, or rotor surface issues on some vehicles. The concern is usually more annoying than dangerous at first, but it can become a safety issue if wear is ignored.

Common Symptoms

  • front brake squeal
  • grinding noise when stopping
  • rotor scoring
  • vibration under braking
  • noise at low mileage

How to Fix

Inspect pad thickness, rotor condition, slide pins, and anti-rattle hardware rather than assuming the noise is normal. Dealers may resurface or replace rotors and pads if wear is abnormal, and should verify caliper movement and proper hardware lubrication. If the vehicle has been driven while grinding, rotor replacement is usually required.

GM opened customer satisfaction/field action N232432960 covering replacement of the fuel rail pressure sensor on affected 2024 vehicles because the sensor's output can shift out of specification over time. On the direct-injected 1.2L turbo the ECM trims high-pressure fuel delivery directly from this sensor, so a drifting signal shows up as a hard or extended crank, a rough or surging idle, a stumble under load, and a check engine light for fuel rail pressure performance. Because the symptom set overlaps the far more serious rod-knock complaints, it is worth ruling in or out first: a pressure-sensor fault produces a stumble and a stored fuel code, not a mechanical bang. Early 1.2L builds have also drawn complaints about injectors that clog or stick, which produces a similar rough idle and a misfire code on a single cylinder.

This issue also affects: Cadillac XTS, Chevrolet Traverse, GMC Sierra 3500HD

Common Symptoms

  • Long or hard crank before starting
  • Rough or surging idle
  • Stumble or hesitation under acceleration
  • Check engine light for fuel rail pressure performance
  • Single-cylinder misfire after the car sits

How to Fix

Have the dealer check the VIN against field action N232432960 - if it applies, the fuel rail pressure sensor is replaced free of charge. Otherwise the sensor is a straightforward warranty or roughly $200-$400 repair. If the fault is a sticking or clogged injector instead, GM's intake and injector decarbonizing procedures (bulletins 16-NA-383 and 04-06-04-051H) are the first step before condemning an injector; a single-cylinder misfire that survives cleaning means injector replacement, roughly $350-$600 for one on this engine. Running TOP TIER detergent gasoline is GM's own documented preventive measure for this engine family.
