Recall work is free at a franchised dealer regardless of the vehicle's age, mileage, or how many owners it has had. Check your VIN against the NHTSA database to see what is still outstanding on your specific vehicle, a recall listed here may already have been performed.
AFM oil consumption (5.3L)
majorActive Fuel Management 5.3Ls of this era pull oil past the AFM pressure-relief valve spray and low-tension rings, burning a quart every 1,000–2,000 miles in bad cases, fouling the driver-side rear plug. GM's fixes ranged from an AFM shield deflector and updated valve cover (TSB 10-06-01-008 series) to piston/ring replacement. A federal jury awarded a $102.6M class-action verdict over 2011–2014 Gen IV 5.3L oil consumption (Siqueiros v. GM). Check the dipstick religiously.
AFM lifter collapse / flattened cam lobe (5.3L)
majorAFM roller lifters can collapse or stick, causing a sudden loud tick, misfire codes on AFM cylinders (1, 4, 6, 7), and in the worst cases a wiped cam lobe. Repair means lifters (usually all 16) and often the camshaft. Many owners install an AFM disabler or do a full delete during the repair.
HVAC blend/mode door actuator clicking
minorA rapid clicking or knocking from behind the dash, or air stuck on one temperature/vent, is a failed blend- or mode-door actuator, a classic GM truck fault of this era. Actuators are cheap and most are accessible under the dash; recalibrate by cycling the HVAC after replacement.
Exhaust manifold bolt breakage (ticking on cold start)
moderateThe V8s are known for snapping rear exhaust manifold bolts, causing an exhaust tick on cold start that fades as the manifold expands. The truck runs fine, but the fix is extracting broken bolts, labor-heavy on the driver side. Aftermarket bolt kits are cheap; the labor is not.
Cracked dash pad above airbag seams
minorGMT900 dash pads commonly crack near the passenger airbag seam and speaker grilles, especially in hot climates. Cosmetic only, but a molded dash cap or replacement pad is the fix. No recall, GM goodwill covered some early trucks only.
