What stands out
Engine accounts for 40% of every owner complaint on file for this vehicle — the dominant problem area across 8 categories tracked.
Owners have filed 110 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Owners report the 6.2L engine experiencing sudden, catastrophic failures with no warning lights—the engine locks up mid-drive, shudders violently, and won't restart. At least two owners lost power on active highways surrounded by traffic, and one stalled during a curve and crashed. Bearing seizure is the dominant failure; some engines show metal shavings in the oil. Dealers confirm internal bearing and crankshaft damage. One owner reported a second identical failure after GM replaced the engine under recall.
Valve lifter failures cause cold-start ticking, rough idle, and cylinder misfires. GM issued recalls (N252494000 and N252494001) requiring an oil viscosity change to 0W-40 and a new oil cap, but owners report engines failing the day after this "fix" was applied. Replacement engines are on backorder 2–6 months; one owner has been without a truck for 65 days and is still waiting. A few owners also report excessive oil consumption, DEF system false warnings, transmission limp mode on new leases, and engine stalling in traffic. Dealers consistently say they cannot duplicate electrical stalling issues and that oil consumption is "normal." One dealer told an owner to "drive it until it locks up," then have it towed. Owners are frustrated that GM sold vehicles after issuing stop-sale orders and that repair timelines remain undefined.

Failure modes owners describe
Engine bearing seizure / crankshaft bearing failure
Crankshaft or rod bearings seize catastrophically, locking the engine mid-drive. Owners report sudden loss of engine power at highway speeds with violent shuddering, metal-on-metal grinding or squeaking sounds, and complete inability to restart. Some cases show metal shavings in the oil. Affects vehicles with 7,500–65,000 miles.
When: 7,500–65,000 miles; often with no warning; some failures within weeks of purchase or shortly after recall repair
Symptoms owners cite: Sudden loss of engine power while driving; Violent shuddering during acceleration; Metal-on-metal grinding, squeaking, or knocking sounds; Engine will not restart; Loss of power steering assist; Check engine light may or may not illuminate before failure; Metal shavings visible in oil after failure
Codes mentioned: Engine seizure confirmed by dealer teardown, Internal bearing/crankshaft damage
Repairs/costs cited: Full engine replacement; parts on backorder 2–6 months. Some owners report second failure after replacement engine installed under recall.
Recalls/TSBs owners mention: Recall N252494000 / N252494001 issued; remedy is oil viscosity change (0W-40) and new oil cap—dealers report this is ineffective and some engines fail the day after 'recall fix' (Picoscope inspection). No TSB beyond recall.
Valve lifter failure
Hydraulic valve lifters on the 6.2L engine fail, causing exhaust valves to stick open and cylinder misfires. Owners report a ticking sound at cold start, rough idle, and loss of power. Some cases resulted in full engine replacement; others treated with lifter replacement, though lifters failed again post-repair.
When: 1,200–13,500 miles
Symptoms owners cite: Lifter ticking noise at cold start; Rough idle and misfires in one or more cylinders; Check engine light (often P300 or cylinder-specific codes); Loss of power during acceleration; Exhaust valve stuck open
Codes mentioned: P300 (random misfire), Cylinder-specific misfire codes, High exhaust leakage (>80%) in affected cylinder
Repairs/costs cited: Valve spring and seal replacement; valve lifter replacement. One owner reports lifters failed again post-repair; another required full engine replacement.
Recalls/TSBs owners mention: No formal TSB or recall specifically addressing lifter failure; treated on case-by-case basis as warranty repair.
Camshaft / variable valve timing (VVT) failure
Camshaft or VVT system fails, causing engine stalling, rough idle, misfires, and loss of power. Owners report check engine light related to valve timing, and in at least one case, the vehicle stalled during a curve at highway speeds, causing a crash.
When: 10,500 miles; one crash occurred after repeated unaddressed complaints
Symptoms owners cite: Check engine light (variable valve timing codes); Rough idle and misfires; Sudden loss of power while driving; Engine stalling at highway speeds
Codes mentioned: P3187 (fuel pump pressure low), VVT/camshaft timing codes, 3rd stage valve timing issues
Repairs/costs cited: Camshaft replacement attempted; problem recurred post-repair with same codes. One case resulted in vehicle crash.
Recalls/TSBs owners mention: Dealer unable to replicate issue or properly diagnose; no formal recall or TSB.
DEF system malfunction
Diesel Exhaust Fluid (DEF) system incorrectly reports low fluid level even when tank is full, triggering false warnings and speed-limiting limp mode. Occurs during towing or sustained highway driving. System reports 300–298 miles range remaining repeatedly despite multiple top-offs.
When: Early in ownership; one case at 4,000 miles
Symptoms owners cite: False 'DEF Empty, Refill Now' warning when tank is full; Speed limiter activation (speed limited to 65 MPH); Countdown warning of speed limitation in 300+ miles; System blocks access to other dashboard functions (tire pressure, transmission temp); Issue recurs after refilling tank
Codes mentioned: DEF level sensor fault (implied)
Repairs/costs cited: Dealer has had vehicle 3+ weeks with no repair attempted; no parts identified.
Recalls/TSBs owners mention: None documented; vehicle in service awaiting diagnosis.
Engine stalling at low speeds or in traffic
Engine shuts off unexpectedly while idling or driving at low speeds (under 10–40 MPH), forcing vehicle into neutral. Owners can restart by pressing the start button, but repeated stalling in traffic poses rear-end collision risk. No clear root cause established; dealer unable to duplicate.
When: Recurring; one case at 2 months post-purchase; another 2 incidents in 45 days
Symptoms owners cite: Engine shuts down without warning; Vehicle shifts to neutral automatically; Displays 'Press Start Button to Restart'; All other systems (entertainment, displays) remain active; Occurs during slow traffic or at idle
Codes mentioned: None retrieved; dealer unable to replicate or diagnose
Repairs/costs cited: No repair offered; dealers unable to duplicate issue.
Recalls/TSBs owners mention: None; dealer unable to diagnose.
Transmission valve body failure (Limp Mode)
Transmission valve body fails, causing vehicle to enter limp mode with severe power loss and hard shifting. One case reported 'Reduced Acceleration' warning on a new lease truck with only 7,500 miles; dealer confirmed four other identical trucks with the same fault.
When: Less than 6 months; 7,500 miles on lease vehicle
Symptoms owners cite: Reduced acceleration warning; Unable to shift into reverse; Hard transmission shifts; Vehicle unable to fully accelerate
Codes mentioned: Transmission limp mode activated
Repairs/costs cited: Valve body replacement ordered; parts unavailable; no timeline for repair after 1+ month.
Recalls/TSBs owners mention: No response; GM has not provided replacement parts, buyback option, or timeline.
Air intake manifold mismatch post-recall
After manufacturer engine replacement during recall, dealership identifies non-original air intake manifold installed, triggering check engine light. Owner claims manifold was original when truck was purchased pre-owned, never approved its replacement, and should not pay for corrective action after recall service.
When: Post-recall engine replacement
Symptoms owners cite: Check engine light after recall repair; Non-original air intake manifold identified on new engine
Codes mentioned: Air intake manifold code (not specified)
Repairs/costs cited: Dealer quoting ~$900 for original manifold replacement post-recall.
Recalls/TSBs owners mention: Recall N252494000/N252494001 engine replacement performed; dealership blames original pre-owned purchase for non-original part; manufacturer not addressing owner's complaint.
Engine oil consumption
6.2L engine burns or leaks oil excessively, requiring more frequent changes than manual specifies. Dealer states this is 'normal' for the engine. One case showed dipstick with no oil day after recall 'fix.' Contributes to bearing failure risk.
When: From first oil change onward; one case noted oil depletion within 2,000 miles post-recall inspection
Symptoms owners cite: Excessive oil consumption between changes; Low oil level warnings; Dipstick shows no oil despite recent fill-up
Codes mentioned: Low oil pressure warnings
Repairs/costs cited: Dealer recommends oil changes every 5,000 miles instead of 7,500 miles; no investigation of root cause.
Recalls/TSBs owners mention: Dealer advises 'oil consumption is normal for this engine'; no TSB or warranty coverage adjustment.
