ENGINE
We purchased the vehicle used in April 2025 with 79,851 miles. All service records were documented via Carfax. Vehicle was in impeccable condition. We drove it for approx. 8,000 miles until July 10, 2025, when a loud knocking sound started coming from the engine - approx. mileage 87,600. We drove the vehicle home 350 miles. The knocking sound continued and got slightly worse. We drove it to the nearest dealer (30 miles) and the mechanic said it sounded like a camshaft problem. However, they could not get it in for over 60 days. We drove to another dealer (45 miles). The mechanic said he thought the entire engine was bad. We left the vehicle there and about a week later they were able to confirm that it was TOTAL BEARING FAILURE. Mileage 88,054. We were told that a new engine was needed as well as a radiator and new oil lines, etc. Total estimate $18,000. They also said there was no timeline they could guarantee because of the current GM recall. Of particular note and concern...at no time did the 'check engine' light come on or any other warning system activate. Both mechanics were genuinely perplexed at this. The repairs were ordered and the vehicle is now repaired. However, GM has not confirmed a cost share for the repair billing and we are now almost 60 days since they received the paperwork from the dealer so we still do not have our vehicle back. We filed a complaint with GM and a case number was assigned so they are fully aware of the issue as is the dealer who did the repair.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The wireless charging pad in the vehicle below the climate control system. Yes, it is. The charging component malfunctioned and overheated the back of my phone when it was set in the console while driving. I had no intention of charging my phone, but instead place my phone down while driving. When I picked up my phone at a stop light, I laid it in my inner thigh when the light changed. The burning was so intense and unexpected I swerved into oncoming traffic and lost control, momentarily of the vehicle. I have recreated the incident in a controlled environment myself and the issue is still active. I am happy to have the issue confirmed independently. I gave notice to the dealership after it happened with no concern or further investigation. No, the vehicle has not. No, no warning at all. In fact this is my 3rd GMC Yukon since 2016 and all 3 have had the wireless charging pad, I have had the same phone as my last one. I never had an issue or experienced anything like this.

ENGINE, ELECTRICAL SYSTEM
My vehicle, with only 2,400 miles on the odometer, has been diagnosed as requiring a full engine replacement. While driving on the interstate, a warning message appeared indicating reduced acceleration. I was able to exit the freeway safely, but the vehicle could no longer maintain adequate speed to match traffic flow. Prior to this, the check engine light came on, but no issues were reported in the vehicle’s status system. I contacted OnStar, and they advised me to take the vehicle to a dealership within seven business days. It has since been at the dealership awaiting parts. Upon further research, I discovered that this issue appears to be widespread. General Motors has issued a technical bulletin addressing the problem, which involves complete engine replacement. Additionally, the audio system intermittently emits a loud crashing noise that is startling and potentially dangerous—it has caused me to veer off the road due to its intensity. This issue also seems to affect other 2025–2026 Yukon and Tahoe models.

The vehicle was not repaired. The vehicle was then taken to another dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 100,000.

ENGINE
My 2022 Yukon with the 6.2 engine locked up on a mountain highway in Wyoming. There were no prior symptoms — the engine suddenly lost power and shifted into neutral, forcing me to pull over. The biggest issue was that once the vehicle stopped, it couldn’t be shifted into neutral, which could have caused a secondary collision. The dealer who sold the vehicle didn't treat this seriously and sold as inspection passed vehicle.

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.

My GMC Yukon with 6.2 is using 1 quart of oil every 1000 miles. An oil consumption test was performed and documented with the dealer. In addition there is now a very rough idle while at a stop. The date on the engine build is just months ahead of the current recall.

I bought a car in early 2024 ive had it for 1.5y I recently went to trade it in for something more suitable for me and they ran a carfax and mileage rollback popped up and I had no clue to begin with. They rolled back 100,000 miles on the vehicle. They’re blaming the finance company but they can’t because the finance company never had the vehicle in there possession

Driving on loop 20 overpass on Hwy 59 in Laredo Texas suddenly the engine lost power and started to skip and miss fire while a loud tapping noise was generated, due to the loss of power and skipping, alarms showed in the main console requiring immediate service to the engine, traction and braking sys, the lack of engine power place me in a very critical and unsafe situation wherein I was about to be rear collision by the vehicle behind me. This event happened on October 17th, 2025 . I brought the vehicle to Powell Watson Motors who is the GMC dealership in Laredo Texas for inspection but they refused to accept the vehicle due to the age of the vehicle.

ENGINE, ELECTRICAL SYSTEM, SEATS
I purchased the vehicle in July 2024. I drove the car for 10 days, and when I was driving 65 mph, the check engine light blinked three times and then went off. After that, the engine made a sound that was not there before. I took the vehicle to the dealership and they had the car for many weeks, concluding that the lifters broke and the engine needed to be replaced. The dealership said they replaced the engine and the car was returned to me towards the end of August. Since then, the AC has been worked on three different times in the past year and on the third attempt, there is finally cool air coming out of the driver's air vents. The driver's seat AC blowers malfunctioned and were repaired. The dealership put the original engine's belt back on and then broke. The electric system inside glitches from time to time when you first start the car. The front windshield wipers will randomly swipe while driving. After getting a regular oil change, the car sprang an oil leak due to the cap not being tight enough. Over the past 5 months, there has been a random popping sound in the front driver's side area when coming to a stop that two dealerships can not figure out. The belt in the engine still makes a high-pitched sound when first starting up and lasts for about 1 minute. While in park or sitting at a light, the engine will idle up and down from time to time. The vehicle has been worked on by the dealership where it was purchased and also a GMC dealership.
