2023 GMC YUKON Complaints

I took my SUV (Yukon SLT 2023) to the GMC Dealership 4/5 months ago because of 2 recalls, Failed Brake Fluid Leak Detection and Serial Data Gateway Model. The car was repaired according to the dealership. About 2 weeks ago, I entered my garage to auto start my vehicle and my SUV would not auto start. I waited a few minutes and tried to start it again from inside the vehicle and it started. When it started, the engine light was on and on the dashboard, brake system failure was displaying. It was very strange. So, I let my vehicle idle for a couple of minutes and tried to move the car in the garage. The car started jerking when I put it in drive and a message displayed on the dashboard telling me not to drive my SUV over 40 mph. The brake system failure and engine light were still on. It was very strange. I parked my SUV and let it sit. I'm taking my SUV back to the dealership on Thursday. I'm thankful I wasn't on the highway traveling to work, who knows what could have happened. There are massive problems with these vehicles, brakes, engine, computer systems, etc. I do not feel safe driving my SUV. I drive 41 miles each way for work and I don't feel safe driving this vehicle now with all the recalls, including the engine.

While driving at highway speed we experienced a bearing failure that let to an engine replacement. The engine was subsequently replaced for galling from the piston arm. No warnings or engine malfunction notices occurred prior to the incident. It is my understanding there is an investigation into this specific problem with the 6.2L GMC engine. We were fortunately able to exit the freeway and immediately stop the vehicle to avoid any further safety risks.

While traveling on vacation, my family and I experienced a catastrophic engine failure in our GMC Yukon Denali, leaving us stranded in a small Texas town. After having the vehicle towed to the nearest dealership, we were informed that the engine is seized and requires a full replacement. Unfortunately, the dealer has no estimated timeline for when GM will be able to provide the necessary replacement engine, leaving us in a difficult and uncertain situation. This has caused significant disruption and hardship for my family.

Complete engine failure while driving. Resulting in GM replacing the entire engine after only 15K miles (new vehicle).

The contact owns a 2023 GMC Yukon. The contact stated that while driving on the highway at 60 MPH, there was an abnormal sound coming from the engine. The contact stated that the check engine warning light was illuminated. The vehicle was taken to a local dealer to be diagnosed and the contact was informed that there were metal fragments inside the engine. The contact was informed that the engine needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The manufacturer was notified of the failure. The approximate failure mileage was 31,000.

I have had this vehicle serviced twice for the electrical issue on the running boards. While driving and while parked the running boards constantly deploy and store on their own or get stuck at a half way position. This will happen even if I have them turned off or on.

On [XXX] while on vacation out of state with my family our 2023 GMC Yukon XL Denali stalled out on [XXX]. After safely navigating through 5 o'clock traffic just outside of Atlanta, the vehicle would not turn over or even attempt to start back up. We contacted onstar for assistance and was advised to stay with the vehicle while they dispatched a tow truck. After approximately 2 hours we contacted onstar again and was advised a tow truck wouldn't be available until morning. We then were able to obtain a ride with Lyft that totaled over $100 with 5 people and was given a $50 credit. I was forced to use Hilton Honors points to book a hotel. Then after the next morning around 10am I was advised the tow truck was enroute to the car. I then took an Uber to Enterprise where I was able to get a rental vehicle. And made my way to the dealership that our Yukon was towed to. After speaking with the service advisor I was told they wouldn't even have a diagnosis for a couple weeks. So we proceeded to head home (with the rental breaking down and several other issues we had to overcome). After we were able to get another rental vehicle, we made it home around 2am. We returned this rental vehicle as it was not suitable for our family, and contacted GM in hopes to get a rental vehicle while our $120k vehicle is sitting in the parking lot of a dealership 8 hours from our home. Only to be told they'd allow $44/day for a rental and we would need to rent it initially and they would reimburse us after we submitted our receipts. Unfortunately $44/day does not get us anything that can accommodate our family and finances are not allowing for this at this time. So we are managing with 1 car. On 1/9, we received a call from the dealership stating our engine was locked up, non repairable and they were waiting for guidance from GM. Then on 1/23 I was then advised by my GM rep that she was transferring the case to someone else and they would advise when the new engine has shipped. Unacceptable INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I
