2022 GMC SIERRA 1500 Complaints

coolant control valve failed, truck cannot be driven due to overheating, Dealer has said due the national backorder, it could be 2 months before they receive the replacement part. There is a significant national backorder on the engine coolant flow control valve for 2020–2025 GMC Sierra and Chevrolet Silverado trucks equipped with the 3.0L Duramax (LM2/LZ0) diesel engine. Many owners are reporting wait times of several weeks to months, with some vehicles sitting in repair shops for over 70 days.

The contact owns a 2022 GMC Sierra 1500. The contact received notification of NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING). The contact had parked the vehicle in a parking space when the engine seized. No warning lights illuminated. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that the fuel system control module had failed. The contact was informed that the part to do the recall repair was not yet available. The vehicle remained at the dealer unrepaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 90,000.

L87 Catastrophic Engine Failure on second engine after 6300 miles. This is the second issue with the 6.2L engine in my Sierra 1500. The first engine passed the L87 Engine Loss of Propulsion field action and then suffered Catastrophic Engine Failure a month later. The replacement engine procedure took over 3 weeks to perform and no rental or loaner vehicle was provided by GM or the servicing dealership. The vehicle is currently in the service department at another dealership awaiting the 2nd engine replacement, but it has been over 2 weeks since the engine failure. This servicing dealer has provided a vehicle to use. This has been a very frustrating ordeal and I feel that resell and value of this vehicle has been compromised and GM has done nothing to offset this with me.

Transmission locked up after leaving a stop sign. Rear wheels locked and vehicle was inoperable. Dealership repaired with replacement transmission valve body parts under warranty.

The vehicle is subject to Safety Recall N252494001 (NHTSA Campaign 25V-274) due to manufacturing defects in the engine crankshaft and connecting rod bearings. • Component/System Failed: The 6.2L V8 (L87) engine crankshaft and connecting rod assembly. The engine is available for inspection upon request. • Safety Risk: The defect can cause catastrophic engine damage and sudden loss of propulsion while driving, significantly increasing the risk of a crash. • Dealer/Manufacturer Confirmation: The problem was confirmed via the issuance of Safety Recall N252494001. A dealership inspection was performed previously as part of the recall. • Warning Signs/Symptoms: Common symptoms include engine knocking, check engine lights, and hesitation before sudden failure. The Issue with the Remedy: Federal law (49 U.S.C. § 30120) requires manufacturers to remedy safety defects "without charge". As a permanent safety remedy for this defect, GM has mandated a switch from 0W-20 to 0W-40 (dexosR) oil for the life of the engine to prevent bearing failure. However, the dealership and manufacturer are refusing to provide this mandated safety spec change without an ongoing $85 surcharge per oil change. While they performed the initial "inspection" oil change for free, they are now using the recall-mandated spec change to create a financial burden on the consumer. Because 0W-40 is now the mandatory factory requirement to prevent the safety defect, charging a premium for it constitutes a failure to provide the recall remedy "without charge." General Motors refuses to offset this cost, effectively penalizing the owner for a manufacturer safety defect. The dealership is also failing to honor my Platinum Wrap warranty and GM Prepaid service contract to perform the continued oil changes without additional charges.

Transmission has failed twice in 2023, dealer carried out repairs but still the Transmission started shuddering after every 1000 miles, truck has been in service centre for almost 12 times for the repeated issue but no permanent solution, after my bumper to bumper warranty got over in 2025 September again service Transmission sign appeared and got my valve body replaced on January. after a month on feb the same message appeared again to service transmission and they refused to cover the issue in warranty and asked me to pay almost 7k dollors to get it repaired.

While driving I get a reduced acceleration warning on my dash cluster, drastically reducing horse power. My check engine light came on. This has happened before. I checked the code and it was a P1098 code. After researching I found out it was the Engine coolant control valve. My fan is constantly running. This issue is ongoing. This seems to be a common occurrence with my vehicle year.

My GM Dealership completed the GM 6.2 Engine Inspection and recommended Oil Replacement as part of the 6.2 Engine Recall. Roughly 5,000 miles after this service, the engine failed. I attempted to accelerate from 45-65 miles per hour while getting on the highway, and the engine seized up. I was able to coast/steer the vehicle to the side of the road. The vehicle's starter could not crank the engine. I had the vehicle towed to the shop where the dealership confirmed the engine had seized. The dealership and GM replaced the engine under a warranty repair. I am making you aware of this situation, as the manufacturers suggested solution to the engine issue (The Change in Oil Type, Filter and Cap) did not prevent the engine from failing.

engine recall 6.2 L-87 , after Pico scoop Test, which my truck passed, its using 2 plus quarts of oil per 1000 miles, the dealer has it and is saying they can find nothing wrong per the gm tech that is telling them to check this and that. Ok, oil is going somewhere, I want the motor replaced , they want to continue the oil consumption test, my thing is wasting my time to continue driving and bring back to it back for a low oil reading, Its not gonna fix its self by driving it. I understand gm wants to figure out why, but it should not be at customers time , replace the motor all ready, something is wrong. the first 1000 miles after a oil change and they put die in the oil to check for leaks. When They check the oil level friday 02/06/26 the oil did not read on the dip stick.

The front forward-facing camera module has failed, causing cruise control and driver-assistance features to become inoperative. Dealer diagnosis indicates the front camera must be replaced and recalibrated in order to restore cruise control and safety systems. This failure disables cruise control and driver-assist features that were standard equipment on the vehicle at purchase, resulting in a sudden loss of functionality while driving. The dealer has provided a repair estimate of approximately $1,150, including parts, labor, and required calibration, at owner expense. Based on similar reports from other owners, this appears to be a recurring issue affecting this model year.
