Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I was driving my vehicle and exiting the hw. The rear wheel of the driver side broke off and separated from the car which caused my car to hit the cement beerier on front and the side of the driver side of the vehicle. Then the car turned 180 degrees and hit the beerier on the passenger side and the rear of the car. The air bags never deployed and we discovered that the wheel brook off of the rear axe. No damage to the wheel. Several industry exports stated that this should never happen.”

“I purchased my used GMC YUKON from a used car dealership 3/28/26. I signed the papers for the agreement while I was driving the vechicle home I lost power and it wouldn't go forward with gas applied. The check engine light came on, I pulled the suv over and it was towed. The code that popped up 0700 and 02723 both codes having to do with the transmission.”

“I brought my 2018 yukon denali to dealer to see if there was a recall on the transmission. Warm or cold didn't matter because the truck jerks and slips constantly. Even when decelerating it will shift wrong and clunk. I have been complaining about this since the first year I bought it. This truck is a safety hazard when crossing traffic while turning. I have been to the gmc dealer many times and no recall.”

“NHTSA's recall number 25V-274. This vehicle should fall under this recall it happed to the this motor at 58k miles and I had to put a whole motor in it at 58k miles in 2022. The Yukon Denali has the L87 V8. I bought the new motor threw GM so it should be tied to this vin number”

“The 2018 Yukon has been at the dealership several timeswaiting for a valve body for the transmission. There are valve body recalls for other year GM vehicles with the same transmission, but not for the 2018 model even though it appears to be the same part number. I don’t understand how this 2018 model apart of the recalls when it’s got the same issues as the newer ones. This is the second Yukon I’ve bought in the last seven years and the other one had the exact same issue.”
