ENGINE, FUEL/PROPULSION SYSTEM
My 2021 GMC Yukon Denali is affected by NHTSA Recall #25V-274. The recall notice states that defects in the engine’s connecting rod and/or crankshaft can cause engine damage and failure, resulting in sudden loss of propulsion and increasing crash risk. The recall status for my vehicle is currently listed as “Incomplete – Remedy Not Available.” My dealership confirmed that no repair is available and further told me that GMC will not authorize a buyback, trade-in, or loaner vehicle until a remedy is developed. This has left me with an unsafe vehicle that cannot be repaired, yet I am still obligated to make monthly payments. This defect creates a serious crash risk because the engine may fail and the vehicle could lose all propulsion without warning. My family is forced to either risk driving a defective vehicle or go without reliable transportation. Dealer Interaction •Dealer confirmed that the recall is active but has no available remedy. •Dealer stated GMC will not authorize a buyback, trade-in, or loaner vehicle until the recall repair is developed. •I am effectively stranded with an unsafe vehicle and no safe options. Remedy I am requesting that GMC be required to: 1.Buy back my vehicle under federal recall and warranty obligations; or 2.Provide a safe, comparable loaner or replacement vehicle at no cost until the defect is remedied. If a loaner is provided, I will continue making my monthly payments on my Yukon Denali.

ENGINE
While driving on the and merging onto the highway, the check engine light and other alerts came on our 2021 GMC Yukon. There was a fluttering noise coming from the engine and the vehicle started to have decreased acceleration. We had to immediately exit the highway and park the vehicle. We then had to take our vehicle to our regular mechanic since GMC dealership was backed up and we needed the vehicle repaired. Our mechanic has identified the issue to be with the engine. The lifters in the engine broke which also damaged the cam shaft. This is a very costly repair. Our vehicle is four years old and out of warranty since we have 80k miles on our four year old Yukon. This problem with the GMC L84 5.3L V8 engines seems to be a common issue and other owners have posted their frustrations on various websites and there is currently no recall on this 5.3L engine. This is a safety issue and a recall should be issued like the one for the 6.2L engine. Why is there no recall for the 5.3L engine? A recall needs to be issued for the GMC L84 5.3L V8.

ELECTRICAL SYSTEM, ENGINE
I attempted to start my vehicle and it turned over and at the end of trying it sounded like it wanted to start. This repeated itself with no change. I contacted the dealer which I purchased it from and the service mgr said it was the fuel pump control module. Numerous 2021 Yukon had this problem and there is both a service bulletin and a recall for this part. N212332040. My vehicle is NOT on recall. I attempted to have it towed to the local Chevy dealer and was unable to as NO local tow company had the tool to put the transmission in neutral. They all wanted to drag it onto the trailer. Bad design that it can not be put in park if it’s not running. I purchased a replacement fuel pump control module part 13554821 from the dealership. I installed it and the problem was fixed. I have the defective part if needed. This would have been much more of an issue if it happened anywhere other than my house, especially with the inability to put he transmission in neutral !!

FUEL/PROPULSION SYSTEM
While driving back home on the highway (I-95) on February 26, 2025, my truck stopped accelerating right in the middle of the highway and cut off. Tried to crank it back up to no avail. I had it towed to the nearest GMC dealer which is GMC Coral Springs. They did an inspection and immediately communicated that the fuel pump module had failed and needed to be replaced. The only option at the time was to just have it fixed because I was out of warranty. At the time, I had about 100k miles on it and the guy at the dealer told me that he's supriesed it lasted that long as those modules usually go out before 100k mile. I got it fix and on March 1, 2025, the truck was ready for pickup. Fast forwarding, now GMC is recalling the 2021 Yukon with recall N252516900 for the same EXACT issue. I spoke to GMC corporate this morning to see if I can be reimbursed for the cost. When the rep Tina ran my vin, she states my vin wasn't attached to the recall number. So I was trying to understand that the issues are the same, why can't they reimburse me. Same issue on the same year truck. GMC refused to help me. I'm so disappointed because I'm not even sure why my truck wasn't included in the recall but has the same issue. I need your help. Please and thank you. (I contacted the dealer to have the email me a copy of my invoice for the service at the time, however I haven't received it. I will contact them again to see if they can email it again. But I will obtain a copy of it even if I have to drive out ther)

Multiple people including my family are experiencing leaks in 2021 and newer GMC Yukons and Chevy tahoes. The back seatbelt is causing leaks, damaging the interiors. This can cause mold and health issues as well as electrical wiring issues causing accidents due to shortages occurring. Check Reddit on the number of complaints.

ENGINE, FUEL/PROPULSION SYSTEM, SEATS
In January 2021, I purchased a new 2021 GMC Yukon Denali from a GMC dealership, which currently has only about 27,000 miles. To date, several recalls have been assigned and completed for my vehicle. per the websites for GMC and your agency. However, based on published recalls for my vehicle and a repair that is currently underway, I have reason to believe that my vehicle should have been subject to three prior recalls for which it was not [NHTSA ID Numbers: 20V735000 (Front Seat Bolts), 25V274000 (V8 Engine Failure, and 21V739000 (Fuel Power Control Module] Currently, the fuel pump control module is being replaced at a local GMC dealership because it failed last week and left my stranded at home. GMC issued a recall for this in 2021, but my vehicle was not included. Aside from risk and inconvenience, this is also costing my over $300 for a rental. Secondly, though my vehicle's make/model/year is cited in GMC's ongoing engine failure recall, which you are investigating, I have not received a recall notice. I note GMC's financial interest in minimizing vehicle's it recalls for such a costly repair. I have inquired with GMC and two of its dealers and have only received reiterations that my vehicle has not been subject to GMC's recall, which I already knew. I have not been given any explanation for why my Yukon has not been recalled despite my inquiries. Lastly, GMC issued a 2021 recall for front seat bolts; however, I did not receive a notice for my Yukon. I have occasionally felt slight movement in the driver's seat since buying the vehicle. Based on reason and facts, I am alleging that GMC appears to be artificially minimizing recalls and notifications for vehicles that are in fact impacted by defects in their vehicles.

My vehicle is currently in repair due to a known issue with GM. GM has put out a Technical Service Bulletin 20-NA-038 referencing a "well-known" problem with Cylinder 5 failing in 2021 5.3L and 6.0L engines. However, there has not been a recall. Ironically, there were other vehicles brought to the dealership (Sam Boswell GMC in Enterprise, AL) for the same repair on the same day as my vehicle. I'm hoping to get an initiative started for a recall

ENGINE
We experienced catastrophic engine failure consistent with the current outstanding recall. A GM dealership replaced the parts that failed (crankshaft and connecting rods) however, based on the recall that was issued, the serial number on our engine would qualify under the remedies indicated by GM for a complete engine replacement, however, our VIN number is not currently included in the recall even though our year, make and model for the car and engine are consistent with other recalled vehicles. The GM dealer indicated that the catastrophic engine failure was not due to any lack or neglected maintenance and felt that our vehicle should be included in the recall. My wife and two toddler children primarily use this vehicle and I have serious concerns about their safety and would like to feel confident about their use of the vehicle.

My engine is currently experiencing loud knocking/shaking. It worsens as my vehicle is accelerating it is causing my engine to lose ability to accelerate which has posed a safety concern. This vehicle is my main source of transportation for my family. We have taken this vehicle to the dealership where they were unable to service due to the recall not being open and available and i have contacted GM customer service with no remedy to be issued at this time. The dealership cannot perform any maintenance pertained to the recall and yet cannot remedy. I am concerned for my family's safety. I was advised that i shall continue to drive the vehicle until it breaks down or the recall is open for repairs.
