2021 GMC YUKON Complaints

GM may be installing recalled engines into other vehicles through warranty replacements, avoiding recall accountability. I purchased a 2021 GMC Yukon built before recall N252494002. Before my ownership, the original engine failed and was replaced under warranty at 24,339 miles on 9/16/2024. The dealer verbally told me it was new, but it had salvage yard markings and no serial number—indicating it was used. This donor engine was likely from a vehicle later covered by the recall. GM appears not to track donor VINs for warranty replacements, meaning recalled engines can remain in service without repair. This creates a serious safety risk and allows defective engines to escape recall compliance. I urge NHTSA to require manufacturers to track and report donor VINs for used engines and major components installed under warranty so they remain subject to applicable recalls.

Dealership refused to inspect engine and provide new oil in regards to recall, they charged me $208.75 for oil that was supposed to be completed under recall L87 for GM

the electronic solenoid in the valve body failed and it is available for inspection. it was struggling to shift on freeway at speeds of 65 mph and i would lose power. the vehicle was inspected by a gm dealership service man. there were no warning lamps when part started to fail, luckily when I parked the vehicle would not go into gear and then the warning light (check engine light) came on.

Engine started missing out. After taken to dealer, cylinders 5 and 6 were filled with oil. New engine is needed, and is on nationwide back order as thousands of these are effected.

Been working with dealership on engine performance for a year, recall is delayed because of no available parts. I had bought a warranty that replaced the lifters and cam. Also this year the transmission, radiator, pully and belt were all replaced. Engine blew up last night and is back at dealership. I paid $80,000 for this vehicle and have had major issue after major issue with it. Looking into seeing if it qualifies as a lemon. Lucky was going slow when it happened and it didn't cause an accident. Could not get the vehicle into neutral to tow it.

While driving the vehicle, the engine started to make a knocking noise and we experienced illumination of the check engine light. We also experienced engine performance issues with hesistation and reduced acceleration. We were able to take the vehicle to a GM dealer and it was determined that the lifters and crankshaft were defective and need to be replaced. There is a warranty out for 2021 GMC Yukon Denali vehicles that were manufactured less than a year after ours that have currently have a recall issued by GM for the same problems that we experienced. My wife and two young children, ages [XXX] and [XXX] , frequently ride in this car and catastrophic engine failures put their safety and livelihood at serious risk.

Vehicle: 2021 GMC Yukon XL VIN: [XXX] Recall ID: 25V274 (GM Recall N25249400) Mileage: Approx. 35,000 My 2021 GMC Yukon XL was recalled for a potential engine defect. On June 9, 2025, the dealership (Carol Buick GMC in Florida) determined that my vehicle was unsafe to drive and that the engine needed to be replaced under GM Recall N25249400. GM has not delivered a timely fix. The engine remains on national backorder, and as of July 31, 2025, the vehicle has been out of service for over 6 weeks. I was provided a loaner vehicle, but my own vehicle remains undrivable, and no repair ETA has been provided. GM opened two internal case numbers (#[XXX] and #[XXX]), but despite repeated follow-ups, I have received no estimated return date or formal remedy timeline. I believe this delay violates the federal requirement to provide a timely recall remedy under NHTSA regulations, and I am requesting an investigation or compliance review of GM's handling of this recall.
