ENGINEFUEL/PROPULSION SYSTEM
On November 14,2025 my engine failed on the highway going 80 mph to 0 mph in the passing lane. Almost caused a major accident on US23. I’ve asked my dealership Bowman Chevrolet repeatedly to inspect my engine for the recall and have been denied every time. Most recent was October when I had my oil changed and I was told it wasn’t my turn and the recall for my vehicle was pending. I had my vehicle flatbed towed to the dealership where it sits dead in their parking lot. Thank God we didn’t die on the freeway that night. It was a horrible experience.

ENGINEFORWARD COLLISION AVOIDANCE
While driving vehicle on 11/08/2025, vehicle made a popping noise and loss power. We were out of town and had to pay out of pocket to have vehicle towed to a dealership and hour away from our home. Dealership diagnosed issue with engine failure due to lifter fell and caused damage to cam shaft and bore. I will be without a vehicle for an additional 2 to 4 weeks waiting on a back ordered engine from GM, and continue making payments on vehicle as well. This issue seems to be an ongoing problem that GM is ignoring…….GM should compensate towing, car rental, and repair/ replacement charges due to failure.

STEERINGELECTRICAL SYSTEMENGINE
I’m not happy with just a change in oil viscosity because the car has already been on the road for 70000 miles before we were aware of the recall on the engine. Changing the oil viscosity doesn’t help when there is a underlying engine problem it should be replaced not just change your oil and send you on your way because now I’m always wondering and worried if the engine will still fail when my kids and wife are in the car. Furthermore I just had it inspected and the oil changed to new viscosity a week ago and the oil level is already half way on the dipstick so I’m taking back to the dealership to express my concern. If I would have known this was going to be an issue with this suv I would have purchased something else. I’d just like the engine replaced so that I don’t have to worry every time I pull out of the driveway with my family. My power steering assist still whines and there is no open recall on it. I think GMC should be responsible for replacing engines and power steering assembly and power steering motors on 2021 GMC YUKON DENALIS because of the wear and tear they have endured before the recall was taken care of by adding a different viscosity oil because the damage has already been done.

ENGINE AND ENGINE COOLING
See attached document for complaint. On [XXX], I purchased a certified pre-owned 2021 GMC Yukon Denali for $85,481.76. Since then, I've had multiple service appointments prompted by dashboard alerts, OnStar reports, and noticeable engine hesitation and knocking noises while driving. The attached invoices reflect services I paid for based on dealership recommendations to address these issues. Unfortunately, this experience has been convoluted and stressful. I've received conflicting information from GM representatives at 1-866-467-9700 and various dealerships. In fact, several dealerships have expressed strong concerns about the qualifications of the hotline staff to provide accurate guidance regarding the recall. Despite the time, energy, and financial resources I've invested, I remain a loyal GM customer and proud owner of a 2017 Chevrolet Colorado, 2022 Cadillac XT6, 2022 Buick Encore GX, and the affected Yukon Denali. Considering the circumstances and the unresolved issues surrounding this recall, I respectfully request financial compensation close to the original bill of sale amount of $85,481.76. I believe this would be a fair and appropriate gesture given the extent of the stress, inconvenience and cost I've incurred.
