What stands out
Engine accounts for 54% of every owner complaint on file for this vehicle — the dominant problem area across 7 categories tracked.
Owners have filed 79 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.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Under Field Actions N252494000, N252494001, the service procedure includes performing a PICO test on vehicle engines within the identified suspect VIN population. If the engine passes the PICO test, the engine oil will be changed from 0W20 to Mobil 1 Supercar 0W40 dexosR. From that point forward, the engine must use 0W40 dexosR oil products for all future oil change services.

The failure pattern owners describe
The 2024 GMC Yukon with 6.2L V8 (L87) engine is accumulating complaints of catastrophic engine failure without warning. Owners describe sudden loss of power at highway speed—the engine simply shuts down, the vehicle shifts to neutral, and power steering and brakes fail. Most report no warning lights beforehand; a few see check engine light flash only after failure begins. Mileage at failure ranges from 3,800 to 32,000 miles.
Dealers consistently find the same internal damage: spun rod bearings, crankshaft bearing failure, damaged connecting rods, and metal shavings floating in the oil. In some cases, owners report a loud knocking or grinding noise just before shutdown; in others, complete silence until the engine quits.
General Motors issued Recall 25V274 in April 2025 for connecting rod and crankshaft manufacturing defects in the L87. The recall remedy is an inspection for DTC P0016, then either an oil change to 0W-40 or engine replacement if the inspection fails. However, owners report that recall parts remain unavailable months after the notice; dealers cannot activate VINs in GM's system, and some vehicles sit at dealerships for over 100 days without any repair being performed. Three owners explicitly report passing recall inspection and receiving the preventive oil change, only to have the engine light return days or weeks later—or to have the engine seize outright in one case four months after the "repair."
GM has acknowledged 12 alleged crashes and 12 injuries. Owners describe near-misses on busy interstates, blocked traffic lanes, and families stranded in cold weather. Engine replacement lead times quoted by dealers span 2 to 7 months. One owner reports the replacement engine itself failed identically 150 miles after installation.

Failure modes owners describe
Loss of motive power and engine shutdown
Engine loses power suddenly without warning, vehicle shifts to neutral, and engine will not restart. Occurs at highway speeds, during stop-and-go driving, or at stop lights. In many cases, owners report coasting to shoulder successfully; in others, they narrowly avoid secondary collisions.
When: Mileage ranges from 3,800 to 32,000 miles; timing varies from weeks to months after purchase
Symptoms owners cite: Sudden loss of engine power; Automatic shift to neutral; No warning lights or lights appearing too late; Loss of power steering and braking; Engine will not restart or takes multiple attempts; Intermittent power loss before catastrophic failure in some cases
Codes mentioned: P0016, P0305, Check engine light (delayed or absent in many reports)
Repairs/costs cited: Engine replacement required; dealers cite bearing failure, crankshaft damage, rod damage, and internal mechanical failure; metal shavings and debris found in oil; lead time for replacement engines quoted at 2–7 months by owners
Recalls/TSBs owners mention: Recall 25V274 (N252494000) issued April 24, 2025 for 6.2L V8 (L87) connecting rod and crankshaft defects; remedy: DTC P0016 inspection, oil change to 0W-40 if passed, engine replacement if failed; related bulletins N252494001, N252494002, N252494003; GM acknowledges 12 alleged crashes and 12 injuries; phased inspection approach without owner-requested timing; engine replacement covered under warranty but delayed due to parts shortage
Engine bearing failure and internal seizure
Rod bearings, main bearings, or crankshaft bearings fail, causing metal particles to accumulate in oil, knocking sounds, and complete engine seizure. Internal inspection reveals spun bearings, damaged connecting rods, and metal debris.
When: Occurs between approximately 6,450 and 24,000 miles; some failures happen within days or weeks of initial repair attempts
Symptoms owners cite: Loud knocking or grinding noise from engine; Metal rattling or dropping sound; Abnormal engine vibration; Low oil pressure warning (sometimes); Engine seizure and complete loss of power; Grinding or clunking at startup
Codes mentioned: P0305 (cylinder 5 lifter), Low oil pressure warning codes
Repairs/costs cited: Engine teardown reveals spun rod bearings (1, 3, 5), main bearing failure, damaged connecting rods (up to 4 of 8), crankshaft damage; metal shavings in oil confirmed by dealers; one vehicle failed again 150 miles after replacement with identical failure; one vehicle experienced cylinder 5 and 6 seizure after camshaft/lifter repair and required full engine replacement
Recalls/TSBs owners mention: Engine replacement required; related to Recall 25V274 (L87 defect); GM acknowledges bearing failures in Engineering Analysis EA25007; NHTSA query RQ26001 tracking post-remedy failures
Camshaft and lifter failure leading to secondary engine damage
Intake valve detaches from camshaft, lifter fails, or both wear prematurely, causing valve damage and subsequent engine failure. One case shows initial repair for lifter/camshaft damage, followed by reoccurrence of failure (seizure) within 2,500 miles.
When: Approximately 14,589 miles for initial diagnosis; reoccurrence within 2,500 miles after dealer repair
Symptoms owners cite: Abnormal knocking sound from engine; Reduced acceleration or hesitation; Check engine light illumination (DTC P0305 for cylinder 5); Intake valve detachment noted during inspection
Codes mentioned: P0305 (cylinder 5 lifter)
Repairs/costs cited: Initial repair: lifter and related parts, camshaft, and coolant pump replacement; subsequent inspection revealed metal shavings in oil, requiring full engine replacement; one report notes camshaft replacement on one vehicle, then seizure of cylinders 5 and 6 requiring full engine replacement after 4.5 weeks of repair and 25 miles of driving
Recalls/TSBs owners mention: Covered under recall investigation; related to L87 defect; repairs attempted by dealers but not resolving underlying bearing/crankshaft issues
Recall inspection failure and persistent check engine light
Vehicles pass recall inspection and receive preventive oil change per recall procedure, but engine light returns persistently days or weeks later, or engine light cycles on and off without a clear error code being retained. Owners report dealerships stating codes cleared themselves without diagnostic confirmation.
When: Post-inspection timing: one case reports oil change in June 2025 followed by seizure in February 2026; another shows persistent light from November 2025 through January 2026
Symptoms owners cite: Check engine light comes on after recall inspection and service; Engine light cycles on and off; Engine light remains on with multiple restarts; Dealership reports code cannot be retrieved or 'cleared itself'; Oil leak discovered after recall service
Codes mentioned: Check engine light (exact codes not retained or reported as cleared)
Repairs/costs cited: Oil filter replaced, oil change performed, but check engine light persists; dealership reports no error code present on scanner despite light being on; owners request thorough diagnostic and feel unsafe driving vehicle
Recalls/TSBs owners mention: Recall 25V274 inspection and 0W-40 oil change performed per N252494002; owners report lack of follow-up or meaningful diagnostic after light reappears; one vehicle (purchased as certified used after June 2025 oil change) seized in February 2026, suggesting recall remedy did not prevent failure
Delayed recall remedy and parts unavailability
Owners notified of Recall 25V274 but cannot schedule or complete inspection due to parts not yet being available in dealer systems or GM randomly selecting vehicles for inspection without clear timeline. Owners forced to continue driving vehicles with known defect.
When: Notices issued April 24, 2025 and later; parts unavailable for months after notice; as of late January 2026, many owners still report no parts availability
Symptoms owners cite: Receipt of recall notice; Dealer unable to activate VIN in GM system; Parts status shows unavailable on VIN lookup; No estimated repair date provided
Repairs/costs cited: No repair performed; owners report waiting periods spanning months with no parts availability; some remain unrepaired as of January 2026; one dealership held vehicle for 106 days (April 10 – July 25, 2025) with no recall repair completed, only multi-point inspection
Recalls/TSBs owners mention: Recall 25V274 issued; phased approach to inspections without owner-initiated timeline; GM directive that owners cannot request immediate inspection; repair parts (likely connecting rods, crankshaft components, or complete engines) not supplied to dealers in timely manner; owners advised manufacturer has not exceeded 'reasonable' time for remedy despite months of delay

Common questions
How serious is the engine problem on the 2024 GMC Yukon?
It's a documented issue but not catastrophic. 79 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
At what mileage does the engine typically fail?
Across the 11 complaints that reported odometer mileage, most engine failures cluster between 12,350 and 26,000 miles, with the median around 21,116. A quarter of owners report trouble before 12,350; a quarter make it past 26,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
