Vehicle has almost 75000 miles. No warnings whatsoever, the GMC app actually reported the vehicle has no issues and all systems are working. The engine began to knock, the transmission was not shifting well, traction control stopped working. Took the vehicle to the local dealership who called me and said it was complete engine failure that is going to require a brand new engine. All of the maintenance is up to date.

ENGINE
I am reporting a serious engine failure in my 2023 GMC Yukon XL (5.3L Ecotec3 V8) at approximately 68,775 miles. The engine began to run rough with a loud chatter noise, and both the check engine light and traction control light activated. Diagnostic tests at the dealer (F.C. Kerbeck GMC) confirmed a P0300 random misfire code and revealed that the lifter on cylinder #5 had collapsed, causing damage to the camshaft lobe. The repair required removing the cylinder head and replacing the lifter, camshaft, pushrods, valves, and associated gaskets and seals. Although I was told this was covered as a ‘goodwill repair’ by GM, I was still charged $3,450 for miscellaneous charges. I find this highly concerning and question whether these charges are consistent with GM’s stated goodwill or warranty policies. In my opinion, a known lifter design flaw requiring such an extensive repair should not result in out-of-pocket costs for the vehicle owner. This failure resulted in a severe misfire and significant performance issues that I believe raise serious safety concerns, including the potential for sudden loss of power while driving. I am submitting this report to NHTSA to ensure this issue is documented and to request that it be included in any broader investigation into GM lifter system failures. Repair invoices are available upon request

FUEL/PROPULSION SYSTEM, ENGINE, UNKNOWN OR OTHER
I own a 2023 GMC Yukon Denali XL (VIN: [XXX] ) currently under active recall for the L87 6.2L engine. GM has no remedy available and has acknowledged a risk of complete engine failure and loss of propulsion, which could occur without warning. This is the primary vehicle I have for transporting my family of seven, including a toddler. I am significantly upside down on the loan, and the dealership cannot guarantee it is safe to drive. I am requesting that NHTSA escalate the urgency and hold the manufacturer accountable for timely resolution or replacement.” INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, ELECTRICAL SYSTEM
The engine system (6.2L V8 L87) in my 2022 GMC Yukon XL failed due to a known manufacturer defect tied to NHTSA Campaign 25V-274. The vehicle is available for inspection upon request. The issue involves the risk of sudden loss of propulsion, which could result in a crash or injury to myself or others. This is a serious safety concern, and I do not feel safe operating the vehicle in its current condition. The defect has been acknowledged by GMC, but there is no remedy or repair currently available. I have contacted the selling dealership (Rick Hendrick Buick GMC, Duluth, GA) repeatedly for the past three weeks with no returned calls. I also contacted GMC corporate, who confirmed the recall but refused a buyback or replacement because no repair has occurred — even though a fix does not exist. They offered a loyalty voucher that does not come close to addressing the safety risk or impact. The problem has not yet been inspected by a dealer or manufacturer because there is no repair action to take at this time. No police, insurance, or third-party has reviewed the vehicle. There were no warning lights or messages prior to the issue — the problem was revealed when I looked up the VIN and learned of the active recall on the engine. I am requesting NHTSA’s support to ensure General Motors provides a replacement vehicle and compensation for this ongoing and unresolved safety hazard. I should not be placed in a position where I am expected to continue operating a vehicle with a known and dangerous defect that has no resolution in place.

POWER TRAIN
Transmission issue - 2021 Yukon XL broke down 5/6/25 while driving with 2 of our children in the vehicle. the RPMs skyrocketed but the vehicle wouldn't go. was hard shifting and speed would not exceed 35ish MPH. message popped up on vehicle that said acceleration throttled and engine light came on. Took it to dealership and it is a known problem. Transmission needs a valve body replacement. This part is on national backorder for months. Spoke with the dealership on 6/5/25 and they still do not have an ETA. They ordered one on 3/19/25 that still has not arrived. I received a case number from GM but they are extremely unhelpful.

ENGINE, SUSPENSION, UNKNOWN OR OTHER
Subject: Formal Complaint – Engine Failure in 2021 GMC Yukon Denali XL VIN: [XXX] Defect Number (GM): [XXX] GM Case Numbers: [XXX] / [XXX] / [XXX] Dear NHTSA Office of Defects Investigation, I am writing to formally report a critical mechanical failure in my 2021 GMC Yukon Denali XL, which resulted in a complete engine failure, rendering the vehicle inoperable and exposing my family to significant safety and financial risks. Despite following the recommended maintenance schedule and driving under normal conditions, the engine failed prematurely. The vehicle has been out of service for over four months, and I have yet to receive a definitive resolution or timeline from General Motors. I have incurred over $13,000 in out-of-pocket costs, including towing, repair estimates, rental vehicles, and continued loan payments on a non-functional vehicle. Key Details: Vehicle: 2021 GMC Yukon Denali XL VIN: [XXX] Failure Type: Total engine failure requiring full rebuild or replacement Time Out of Service: 4+ months and ongoing Financial Impact: $13,335.58 in documented costs GM Defect Number: [XXX] (noted internally by GM) Dealer(s) Involved: Midas Auto Service, Beaman GMC (Nashville, TN) I have made repeated efforts to escalate this through GM’s Case Advisors and Executive Team, but have received no meaningful resolution or written acknowledgment of my request for either reimbursement or a good faith vehicle buyback. Given the safety implications of such a catastrophic failure in a relatively new vehicle, I believe this may represent a broader manufacturing defect or quality control issue and warrants NHTSA investigation. I respectfully request that NHTSA: Log this complaint into your safety database Investigate whether similar failures have occurred in other 2021 Yukon Denali XL vehicles Contact GM for further information regarding this defect and associated safety risk Thank you for your attention to this matter.

We were traveling eastbound on I 70 around 75mph. We received no prior indication that there was a problem. The display read engine oil hot, transmission shifted to neutral, and the entire vehicle shut down. We lost propulsion and were left coasting on a major highway with no power.

Vehicle engine felt it was stumbling when accelerating or seemed like I had ran something over. I don't remember seeing any lights coming on. Pulled over immediately, turned off the vehicle. Turned it back on and drove back home three hours worried it may happen again. I didnt see any warning lights on the trip.

The engine seized on us. It only has 18,000 miles on it. This could have caused a serious accident! There was no warning, no indication, it just died and would not restart. We had to have it towed over an hour to get to our closest dealer (and don't get me started on how they treated me!). We were stopped at a stop sign at the intersection and it just died. Thankfully we weren't driving down the highway or in the middle of traffic, we just ended up blocking people from using our lane for quite sometime. The cops were called for traffic control, but no police report was filed.

Since purchase there has been a grinding noise when the vehicle is initially started up and put into reverse. I am worried that this is associated with the current engine recall that is on this vehicle. There is an increased risk associated with this vehicle as I am paralyzed and unable to exit the vehicle quickly, which is increased drastically when I have toddler and baby in vehicle. This risk comes from the reported 42 potential fires related to this recall in malfunctioning engines. There have been no warning lamps or indicators that have appeared to date.
