2021 GMC YUKON Complaints

Car shakes in drive, car shakes when accelerating, transmission issues, rear differential had to be replaced.

I was driving down the highway when the engine started making a very loud rattling noise. I was able to almost get out of the travel lane. The engine does not restart and is seized. The temperature was 10°f and the closest two was 3 hours away and the vehicle was partially blocking the 2 lane highway on the right side. Unknown inspection status by manufacturer. There was no warning light at any time even after the shutdown. The symptom of the intense loud rattling occurred approximately 60 seconds before complete failure. Just enough time to get to a pull out off a bridge.

Complete failure of infotainment system in cold weather. This is a safety concern because most controls are operated through the infotainment system and can de distracting to a driver who is trying to operate all features of a vehicle while driving. For instance having cold children in the rear seats and not knowing if the heat is activated in the rear of the vehicle and at what temperature or if it is blowing at all. There is no manual indication of rear climate. This is already a safety bulletin for 2021 Yukon that for some reason my vehicle is not included in. GM recall number: N212327470 I want my vehicle included since this is a safety concern ( see above ) and this should be a real recall rather than a notification or safety bulletin.

Font Camera failure. Front camera controls many "safety features" which fail without the camera. Vehicle under mileage warranty amount but not under time warranty ( 3 years ). Camera only covered under bumper to bumper.

In September 2023, mere months after purchasing this vehicle, I was driving on the Mountain Parkway in Eastern Kentucky. Traveling the 70 mile hour speed limit, everything in the vehicle shut down, including my ability to use my breaks. Luckily, I was able to safely coast to the side of the road, which left me quite vulnerable as patrons passed at 70+ miles per hour. There were no advanced warning such as lamps, messages, or other symptoms of a problem. I had the vehicle towed to Hutch Chevrolet in Paintsville, KY where they indicated to me that the crankshaft locked up due to a crank bearing failure. They had to replace the engine and I was out of pocket $12,631.79.

The contact owns a 2021 GMC Yukon. The contact stated that while driving at an undisclosed speed, the transmission warning light illuminated. The vehicle was taken to a local dealer where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired and remained at the local dealer for further investigation. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 24V839000 (Power Train); however, the VIN was not included. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 63,000.

On or about September 28 while traveling N on US 67 it was necessary to stop at a construction stop light. As I started to accelerate a pinging started. I continued roughly 10 miles, to my daughters house. The truck was flat bedded back to Jones Auto Center in Monmouth Ill. The found a bent push rod and bad lifter in the #1 Cyl. Repairs were done per the attached Invoice. Milage was 103,000. On 11/5/2024 while traveling on US 116 @ 65+-MPH the engine froze, with instant stoppage. Flatbedded to Myler Automotive where the engine was replaced per the attached Invoices. Milage was 105907.

Had to replace an engine due to a main bearing failure, not the connecting rod failure thats being investigated. We pulled into the driveway with zero issue and zero suspect of issue, changed the oil as routine 5k miles, went to start it, and it blew the 400A starter fuse. It friction welded the crank to the bearing when I ahit the engine off. It looked like it flaked the coating off the bearing, then due to the recommended 0-20 thin oil, it didn't have the proper protection for metal on metal. Hoping that the main bearings get added to this investigation, because they are the same coating. Same manufacturer.

The contact owns a 2021 GMC Yukon. The contact stated that while driving at 60 MPH, the vehicle's engine shut off without warning. The contact was unable to start the vehicle and was left stranded on the roadway for hours. The contact finally managed to have the vehicle towed to a dealer where they diagnosed the vehicle with a defective engine main bearing(engine failure). The vehicle remained in the dealer's possession where it had yet to be repaired. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 28,450.

My family and I found ourselves stranded on the interstate when our engine failed while we were driving on I-10 at 75 mph. The connecting rod bearing got lodged in the engine, causing it to seize. This put us in an extremely dangerous situation. I believe these vehicles should be recalled. I've been in discussions with GM to buy back the vehicle, but their leadership has declined my request. They are offering to replace the engine, but I do not want this vehicle back.
