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.
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.
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.
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.
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.
