2015 GMC YUKON Complaints

While driving back home from my trip the truck all a sudden made a squealing noise and the engine just stopped. I was on the high way . I was able to coast the vehicle off onto the exit ramp. The vehicle was towed home. The following day it was towed to the repair shop. The shop has confirmed engine failure. Will need to replace the engine . Still waiting for warranty approval.

The contact owns a 2015 GMC Yukon XL. The contact stated that when the vehicle was started, the vehicle started shaking with a tapping sound coming from the engine compartment. The contact stated that there were no warning lights illuminated. The contact stated that while driving at an undisclosed speed around the block, the failure persisted. The vehicle was parked at the residence. The vehicle was taken to a dealer, where it was diagnosed and determined that the lifters in the engine were loose, and the lifters and the right side of the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

Electric Power Steering (EPS) assist was lost while I was driving the vehicle. As a result, I had difficulty steering the vehicle without power steering and almost caused a crash.

While driving my 2015 GMC Yukon Denali on the highway, the vehicle suddenly began shaking and lost power. I immediately exited the highway for safety and had to “nurse” the vehicle about two miles at 10–15 mph to reach home. The vehicle would no longer run afterward. A mechanic later diagnosed a lifter and camshaft failure. This is a known and common issue with GM 5.3L and 6.2L engines that poses a serious safety risk when it occurs at highway speeds. No warning lights or prior symptoms were present before the failure. I did not report it to the dealer, but the vehicle had to be towed to a mechanic for diagnosis. The vehicle is available for inspection.

6.2L engine, collapsed hydraulic lifter AFM failure, required $7400 in total repairs. All lifters, camshaft, high pressure fuel lines, high pressure fuel pump, intake manifold & miscellaneous parts and gaskets replaced by selling Dealer at 94000 miles. No help of any kind from GM or Dealer. This is a WELL KNOWN FAILURE FOR THESE ENGINES!

Vehicle has issue turning at times message on dash says reduced steering had trouble turning and almost caused a accident

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

The transmission shifts hard in low gears. I have done research, and it seems like this is a common problem that a vast amount of these vehicles have. I honestly think that this is has to be looked into for a recall. There is countless information on the web with videos, other owners, and transmission businesses explaining about it.

While driving in downtown boston in heavy traffic (stop and go) braking did not stop the vehicle when removing my foot from the brake and reapplying and the braking was extremely hard, the vehicle nearly collided into the vehicles in front of me. This issue persisted continously for the duration of travel. The issue was not found using the vin provided. This issue MUST be resolved ASAP. This incident was not the first, after owning the vehicle for several months this issue is a major safety issues, specifically when my new young adult drivers use this vehicle. Please help me resolve.
