2023 GMC YUKON Complaints

My vehicle stalled while driving on a busy highway & I had no option but to pull over, which left me & my family in a very dangerous position. Had to remove my daughter's wheelchair onto a tow truck as the vehicle had no power to use the hoist for her powerchair. Again, on the side of a busy road! Towed the vehicle to a GM dealership, who stated there was catastrophic engine failure & the engine had to be replaced. Had no way to transport my daughter until I got a new engine since her hoist was stuck at the dealership. This was our original vehicle, until the sold me another one with the same defect (2024 Yukon for MORE money!). That vehicle was reported in Complaint 11657786.

I am formally requesting a complete refund for my vehicle. It has only 6,300 miles, and the remedy provided for the recall does not adequately address the issue. The recall explicitly indicates defects in the engine components (rods/cam shafts) that may lead to a loss of propulsion. Merely inspecting the vehicle and adding thicker oil does not resolve the underlying problem; it only postpones the inevitable expiration of my warranty. Currently, there are no warning lights illuminated, as the vehicle is not driven frequently. The recall raises significant concerns, and GM should be taking more substantial measures than simply applying thicker oil as a solution. This approach feels like a temporary fix rather than a genuine resolution. I have communicated with the dealership, and have been informed there is currently no solution available for this matter. They are awaiting further instructions on how to proceed. I request a more thorough investigation into this issue for an appropriate refund, and I also wish to have this matter documented for future reference.

My engine failed while I was driving & I had no warning. It was very scary & dangerous. Luckily I was in an area where I could get off the road quickly. It started skipping then lost power. I basically coasted off the road & had to call for help. It was making a bad knocking noise. This happened 2 weeks ago on April 16. It has been sitting at Glynn Smith.GMC dealership since. I was told by the service manager that the engine failed & I will need a new engine. the engines are on back order now. I fear they will replace it with the same problem. I see the recall this week but will changing the oil viscosity really fix it?? Doubtful. Someone is going to get killed or hurt from this problem. I do not want the same issue to happen with a new engine.

Crankshaft bearing failed, leading to engine failure at 65MPH on highway. No warning.

On March 28, my 2023 Yukon Denali stalled on a 4 lane road forcing me to make an emergency stop on the side of the road in a right hand turn lane. The vehicle required towing to a local GMC dealership. They could not restart the vehicle and upon evaluation found metal shavings in the oil. They have recommended an engine replacement. There was no warning, it just stalled and would not restart. My Yukon remains at the dealership and we are still waiting for an engine.

The contact owns a 2023 GMC Yukon XL. The contact stated that immediately after purchasing the vehicle, the battery failed and was replaced on two separate occasions. Additionally, while driving or reversing, the braking system erroneously activated, causing the vehicle to abruptly stop. During the failure, there were no other vehicles or large objects nearby to cause the Forward Collision Avoidance system to activate. The vehicle was taken to the local dealer on several occasions, but no failures were found. The vehicle was not repaired. The manufacturer had not yet been contacted. The failure mileage was 50.

While driving on a busy highway, the engine stalled and could not be restarted. We were in the left lane and thankfully traffic was light and i was able to get to the shoulder. No warning and no check engine light before stall. After numerous attempts and about 15 minutes it did restart. A few miles later same issue and could not restart. We were 200 miles from home. Called GM and they sent a tow truck. Dealer had the car for almost a month and replaced the engine because they found metal in the oil and determined that the main bearings had spun. The concern is that the replacement engine is presumably a 2024 and the issue could happen again.

While driving without any warning the screen said press start. The vehicle shifted to neutral and lost all power while driving down a very busy road on the top of a hill going 55 mph. Once stopped we tried to turn the vehicle back on, vehicle would power on but wouldn’t start just click and screens flash
