What stands out
Engine accounts for 43% of every owner complaint on file for this vehicle — the dominant problem area across 10 categories tracked.
Owners have filed 131 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
The 2024 GMC Sierra has a systemic engine problem that goes beyond early defects. Owners describe catastrophic stalling at highway speeds with no warning—the engine simply dies, often with the dash showing "Press start button again" while the vehicle coasts through traffic. At 35 mph to 75 mph, owners have experienced complete power loss in dangerous situations: toll lanes with concrete barriers, work zones, multi-lane highways, and congested traffic. The vehicle's electronics stay on—radio, OnStar, lights—but the engine won't turn back over, requiring towing.
The root cause appears to be internal engine destruction: metal shavings contaminating the oil filter, spun main bearings, failed connecting rods, and seized bearings. One owner found their oil filter looked like "a glitter bomb went off." Dealers confirm the issue occurs on the 6.2L L87 engine and have seen multiple vehicles with identical failures.
GM issued recall 25V274000 in October 2025 for defective connecting rods and crankshafts. The prescribed fix is a PICO diagnostic test and switching to thicker oil. But this remedy isn't working—owners report engines failing 300 miles, two weeks, even months after passing the recall inspection. One owner's engine seized after the recall despite metal shavings being found during the procedure.
There's also a cold-weather power-loss issue on some 2024 Sierras: below 28–30°F, the truck displays "Reduced Acceleration, Drive with Care" and loses responsiveness. GM says this is normal; dealers reset the computer and send owners on their way, only for it to happen again in cold weather.
Owners are trapped. The recall remedy doesn't fix the problem, parts are on backorder, dealers are told to wait for GM VIN authorization, and GM is refusing buyback offers or loaners. Vehicles that just passed inspection are now requiring complete engine replacement at six figures in lost trade value.

Failure modes owners describe
Engine Stalling/Loss of Propulsion During Highway Driving
Engine shuts down completely while vehicle is in motion, often at highway speeds (35–75 mph), without warning lights or prior symptoms. Vehicle loses all engine power but electronics remain active. Owners report being unable to restart immediately, forcing coasting to safety or stalling in traffic.
When: Occurs unpredictably during normal highway and city driving; some incidents reported within first 1,500 miles, others at 20,000+.
Symptoms owners cite: Engine dies while driving at speed; No warning lights before stall; Dashboard displays 'Press start button again' or 'Restart engine'; Electronics and radio remain functional; Vehicle will not restart immediately after stall; Some instances accompanied by sudden loss of steering assist
Codes mentioned: Check engine light (appears after stall, not before), Unknown sensor codes, Low oil pressure light (intermittent)
Repairs/costs cited: Full engine replacement required; dealers confirm connecting rod/crankshaft failure, main bearing spun, metal shavings in oil filter indicating internal damage. Repair timelines exceed 30 days.
Recalls/TSBs owners mention: NHTSA Campaign Number 25V274000 (Engine and Engine Cooling); recall issued October 2025. Initial remedy: PICO diagnostic test and oil viscosity change (thicker oil). No permanent fix available as of complaint dates; parts backorder; many vehicles fail recall inspection yet experience failures after remedy applied.
Engine Stalling with Automatic Transmission Shift to Neutral
Engine cuts out and transmission automatically shifts from Drive to Neutral without driver input, leaving vehicle stranded or in unsafe position. Occurs without warning and can happen multiple times over short driving distances.
When: Reported at 200 km, 1,600 km, and 1,800 km of driving on a new vehicle; also on used vehicles under normal operation.
Symptoms owners cite: Engine stops suddenly during driving; Transmission automatically shifts from D to N; Vehicle coasts to stop; No warning lights or messages (reported in some cases); Occurs unpredictably across different mileage ranges
Repairs/costs cited: Dealers unable to diagnose or reproduce issue; vehicle reprogrammed multiple times without resolution. No repair completed; vehicle remains parked due to safety concern.
Recalls/TSBs owners mention: Dealers and manufacturer unable to identify root cause; no TSB or recall issued for this specific symptom.
Engine Seizure/Metal Contamination in Oil System
Engine fails catastrophically due to bearing or connecting rod failure, evidenced by metal shavings or filings in oil filter and oil system. Internal engine components circulate metal contamination throughout the engine, leading to complete seizure and inability to turn over.
When: Reported at mileages ranging from 6,500 miles to 83,000 miles; some within weeks of recall inspection and repair.
Symptoms owners cite: Loud clanking, knocking, or ticking sounds from engine; Metal shavings visible in oil filter; Engine shuddering and severe vibration; Sudden loss of power accompanied by engine noise; Engine will not turn over by hand after failure; Oil pressure warning light (low oil pressure alerts)
Codes mentioned: Low oil pressure warning light, Check engine light
Repairs/costs cited: Oil filter teardown reveals 100% metal contamination or 'glitter bomb' appearance. Engine requires complete replacement including radiator (metal contamination spreads to cooling system) and oil cooler line. Repair estimates $6,500–$10,000+ with 30+ day parts wait. Some dealers installed remanufactured engines instead of new.
Recalls/TSBs owners mention: NHTSA Campaign 25V274000 issued; recall procedure includes PICO scope inspection and oil viscosity upgrade. However, many engines pass recall inspection then fail shortly after (within 300–500 miles or weeks). Manufacturer acknowledges L87 6.2L engine defect affecting connecting rod and crankshaft but remedy (thicker oil) does not prevent failures.
Cold-Temperature Reduced Acceleration / Power Loss
Vehicle displays 'Reduced Acceleration, Drive with Care' warning and experiences loss of acceleration power when ambient temperature drops below 28–30°F. Engine does not fail but dramatically loses responsiveness. Check engine light illuminates but dealer resets and reports condition is 'normal' per GM.
When: Occurs consistently when outside temperatures fall below freezing; reported at 2 months into ownership (early winter 2024–2025).
Symptoms owners cite: Dashboard message: 'Reduced Acceleration, Drive with Care'; Check engine light illuminates; Significant loss of power and acceleration response; Engine temperature normal despite condition; Condition repeats on every cold-weather drive
Codes mentioned: Check engine light, Reduced acceleration limp-mode code
Repairs/costs cited: Dealer resets computer and clears code; no parts replaced. Condition recurs when vehicle driven in cold temperatures.
Recalls/TSBs owners mention: GM customer service states condition is 'normal' and not a warranty-covered defect. Dealer unable to provide permanent fix. Case escalated to regional CE Manager but no resolution provided as of complaint filing.
Engine Failure Post-Recall Service (Incomplete Remedy)
Vehicle passes NHTSA recall inspection and receives prescribed remedy (PICO test and oil change to thicker viscosity), but engine fails within weeks or months, requiring full replacement. Indicates recall remedy is insufficient to prevent catastrophic failure.
When: Reported 300 miles, 15 days, and several weeks post-recall completion; one failure at 67,000 miles occurred after passing inspection in November 2025.
Symptoms owners cite: Engine stalls or loses power after recall work completed; Metal shavings found in oil filter despite thicker oil installation; Loud knocking or clanking noise; Vehicle requires engine replacement despite passing recall procedure
Codes mentioned: Check engine light (post-recall), Low oil pressure
Repairs/costs cited: Full engine replacement with same engine type and new/different oil. Some dealers replaced with remanufactured engine rather than new.
Recalls/TSBs owners mention: NHTSA Campaign 25V274000 remedy (PICO inspection and oil viscosity upgrade) applied but proven ineffective to prevent subsequent engine failure.
Excessive Oil Consumption
Engine consumes oil at abnormally high rate, requiring oil level checks every 2 weeks and multiple quarts added between services. Vehicle operated at normal mileage with no visible leaks.
When: Reported at approximately 11,000 miles with no prior symptoms.
Symptoms owners cite: Low oil pressure warning light illuminates intermittently; Oil level drops rapidly between services; No visible oil leaks in driveway or under vehicle; Requires checking oil every 2 weeks and adding 1–2 quarts regularly
Codes mentioned: Low oil pressure warning light (intermittent)
Repairs/costs cited: Dealer inspected engine and found no cause; issue unresolved. No repair completed.
Recalls/TSBs owners mention: No manufacturer response documented; GM not notified.
Transmission Lock-Up After Engine Stall (Cannot Shift from Park)
After engine stalls, transmission becomes locked in Park and will not shift to Neutral or Drive for towing or restart, even after engine restart. Dashboard displays 'Conditions for shift not met' or similar message.
When: Occurs immediately after engine stall events; reported on vehicles with 1,200 to 38,000 miles.
Symptoms owners cite: Engine stalls while driving; Transmission will not shift out of Park after stall; Dashboard message: 'Conditions for shift not met'; Vehicle must be dragged on flatbed instead of rolled with wheels turning; Problem persists even after partial engine restart
Repairs/costs cited: Vehicle must be towed on flatbed using sleds/rollers; wheels cannot roll freely. Requires full engine replacement to resolve.
Recalls/TSBs owners mention: No specific recall or TSB issued for transmission lock-up; occurs in conjunction with engine stall failures covered under Campaign 25V274000.
Oil Cooler Line Detachment (Cold Weather)
Oil cooler line separates from engine connections, allowing oil to spray out of engine while driving. Occurs in cold climates. Related to similar recall in 2019 Silverados but exclusion in recall notice left other vehicles unprotected.
When: Reported at 45,280 miles; occurs in cold climate (Utah winter conditions).
Symptoms owners cite: Oil pressure low warning light illuminates; Loud noise as oil shoots out of engine bay; Vehicle filled with smoke from burning oil; No prior warning or visible leaks
Codes mentioned: Oil pressure low warning light
Repairs/costs cited: Oil cooler line requires replacement; approximately $1,600 repair cost (not covered under warranty in the case reported, owner paid out of pocket).
Recalls/TSBs owners mention: NHTSA Campaign N192220080 issued for 2019 Silverados in Alaska and Canada only; this 2024 Sierra owner was not protected by recall notice despite same factory origin and identical fault.
Loud Chirping/Squealing Noise and Timing Issues
Engine produces loud, persistent chirping or squealing sound during auto-start kickdown and deceleration to stop, consistent across multiple driving sessions. Sound not present in comparable vehicles. Attributed to timing malfunction affecting fuel economy.
When: Present from new (6,500 miles); worsens over time; reported at 8,800 miles.
Symptoms owners cite: Loud chirping sound during fuel saver auto-start; Loud chirping during deceleration to stop (16 mph+); Severe vibration through dash, floorboard, and steering column on acceleration; Sound becomes worse over time; Fuel economy affected; Not reproducible or identifiable on dealer inspections (4 visits logged)
Repairs/costs cited: No repair completed after 4 dealer service visits; parts replaced in some cases (exhaust brackets, mounts) but symptom persists in multiple vehicles with same engine/drivetrain.
Recalls/TSBs owners mention: Dealers cite GM bulletin stating condition is 'normal' for 6.2L V8 engine; no TSB or recall issued.
Smoke from Engine Bay / Exhaust System
Large plumes of blue or white smoke observed coming from rear of engine/tailgate area during normal driving. Smoke visible in mirrors and rear-view sight lines. No physical evidence or burning smell detected at destination.
When: Reported during low-speed left turn and during engine operation at normal conditions.
Symptoms owners cite: Visible smoke cloud above tailgate and behind truck; Blue or white smoke color; No physical evidence of fire or damage at destination; No burning smell reported
Repairs/costs cited: Dealer did not assess smoke incident during appointment; no diagnosis provided.
Recalls/TSBs owners mention: No recall or TSB issued; dealer unable or unwilling to diagnose.
Recall Repair Delay / Incomplete Implementation
NHTSA Campaign 25V274000 issued October 2025 but remedy (PICO test and oil change) not immediately available at dealerships. Owners scheduled for recall but turned away due to parts unavailability or selective VIN activation by GM. Vehicles left in limbo with known defect, unable to be repaired or safely driven.
When: Ongoing from October 2025 through early 2026; some owners waiting 30+ days for parts without resolution timeline.
Symptoms owners cite: Scheduled recall appointment cancelled by dealer; Dealer states parts available but GM is randomly selecting VINs for repair; Owner told GM is fixing new vehicles first; No timeline given for when vehicle will be available for repair; Vehicle unsafe to drive but owner unable to complete recall work
Repairs/costs cited: No repair completed; parts on shelf at dealership but withheld pending GM authorization by VIN.
Recalls/TSBs owners mention: NHTSA Campaign 25V274000 issued; GM implementing staged recall using random VIN selection and prioritizing newer vehicles. Remedy not available for all affected VINs; no buyback or loaner programs offered; customers advised not to drive unsafe vehicles but given no alternative.

Common questions
How serious is the engine problem on the 2024 GMC Sierra?
It's a documented issue but not catastrophic. 131 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 19 complaints that reported odometer mileage, most engine failures cluster between 11,000 and 45,000 miles, with the median around 24,000. A quarter of owners report trouble before 11,000; a quarter make it past 45,000. 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.
