What is the 2010-2014 Chevrolet Silverado 5.3L AFM Excessive Oil Consumption (Low-Tension Piston Rings / Oil Spray)?

Gen IV 5.3L AFM engines burn oil at an abnormal rate — many owners report consuming roughly a quart every 1,000-2,000 miles with no external leak. The accepted root cause is a combination of GM's low-tension piston rings plus the AFM system spraying oil onto the cylinder walls du… Repairs typically run $2,500-$6,000. Severity: high.

What is the 2015-2019 Chevrolet Silverado 8-Speed (8L90 / 8L45) Transmission Shudder, Hard Shift and Torque-Converter Judder?

Silverados with the Hydra-Matic 8L90 (and 8L45) 8-speed automatic are widely reported to hesitate, then shudder, jerk, clunk or 'hard shift' when changing gears — some owners describe a shift so violent it feels like being rear-ended, plus a torque-converter-clutch shudder that f… Repairs typically run $200-$4,000. Severity: high.

What is the 1999-2007 Chevrolet Silverado Brake / Fuel Line Corrosion and Failure (Rust-Belt Steel Lines)?

GMT800 Silverados (and the related GM trucks/SUVs) in salt-belt states are widely reported to suffer rusted-through steel brake lines, leading to a sudden brake-fluid leak and loss of pedal/braking. NHTSA investigated ~6 million 1999-2003 GM trucks and SUVs after an owner petitio… Repairs typically run $300-$1,200. Severity: high.

Silverado 2500HD/3500HD trucks with the 6.6L Duramax LML use the Bosch CP4.2 high-pressure injection pump, which was designed around European diesel and is poorly lubricated by U.S. ULSD. The pump's roller/cam interface can gall and disintegrate, sending metal shavings throughout… Repairs typically run $5,000-$12,000. Severity: high.

What is the 2014-2015 Chevrolet Silverado Temporary Loss of Electric Power Steering Assist (Voltage-Drop Recall)?

GM recalled 2014 Silverado 1500 (NHTSA 17V414, ~690,685 units) and 2015 Silverado/Tahoe/Suburban (over 1 million units) for a temporary loss — and sudden return — of electric power steering assist, especially during low-speed turns. The EPS draws a high-energy load in low-speed m… Repairs typically run $0-$200. Severity: high.

What is the 2021-2024 Chevrolet Silverado 6.2L V8 (L87) Connecting Rod / Crankshaft Failure — Loss of Propulsion Recall?

GM recalled roughly 597,630 trucks and SUVs (NHTSA recall, 2025) — including 2021-2024 Silverado 1500 with the 6.2L L87 V8 — for connecting rods and/or crankshafts that may have manufacturing defects (debris in oil passages or out-of-spec parts). Affected engines can seize or kno… Repairs typically run $0-$12,000. Severity: high.

What is the 2007-2019 Chevrolet Silverado 5.3L V8 Active Fuel Management (AFM) Lifter Collapse and Camshaft Damage?

The 5.3L (and 6.2L) V8 with Active Fuel Management — GM's cylinder-deactivation system that drops the engine to 4 cylinders to save fuel — is notorious for collapsed AFM lifters. The special deactivating lifters (and the lifter oil-manifold/VLOM that feeds them) fail when oil pre… Repairs typically run $1,500-$4,500. Severity: high.

What is the 2014-2018 Chevrolet Silverado Brake Vacuum Pump Failure — Hard Brake Pedal (3.4M-Vehicle Recall)?

GM recalled about 3.46 million vehicles (NHTSA 19V645 and expanded 20V603), including 2014-2018 Silverado 1500, for an engine-driven brake vacuum pump that loses output over time. Debris and oil sludge build up on the pump's internal filter screen, reducing the vacuum that powers… Repairs typically run $0-$600. Severity: high.

What is the 2014-2020 Chevrolet Silverado A/C Condenser Leak — A/C Blows Warm Air (Spot-Weld Crack / Combi-Cooler Failure)?

The A/C condenser on K2XX-platform Silverados is a chronic failure point — the condenser develops cracks at the side spot-welds (thermal-stress fatigue) and the discharge line/hose can flex and crack, both of which leak refrigerant and leave the A/C blowing warm air. It was the #… Repairs typically run $400-$1,200. Severity: medium.

What is the 2007-2013 Chevrolet Silverado Fuel Pump Control Module (FPCM/FSCM) Corrosion — Crank, No-Start?

GMT900 Silverados (and the late GMT800) mount the fuel pump control module / fuel-system control module on an exposed frame-rail bracket where it is constantly hit with road salt, water and debris. The module's connector and internals corrode, and the FPCM then fails to drive the… Repairs typically run $250-$600. Severity: medium.

What is the 2003-2007 Chevrolet Silverado Instrument Cluster Gauge Failure (Defective Stepper Motors) — Speedometer Reads Wrong?

GMT800 (and early-2007 'Classic') Silverados are infamous for instrument-cluster gauge failure caused by defective X27.168 stepper motors and weak solder joints behind the gauges. Over time, heat, vibration and age cause needles to stick, read wildly wrong (e.g., speedometer pegg… Repairs typically run $120-$350. Severity: medium.

What is the 2007-2014 Chevrolet Silverado Cracking Dashboard (UV / One-Piece Dash Pad Failure)?

GMT900 Silverados (and the matching Tahoe/Suburban/Sierra/Yukon) are known for the one-piece dash pad cracking — typically near the passenger airbag seam, the defroster vents and the corners. Owners attribute it to the plastic grade, UV/sun exposure and factory over-tightening of… Repairs typically run $100-$2,000. Severity: low.
