2024 GMC YUKON Complaints

Driving on highway. The vehicle jerked and started to make squeaking, clunky sounds. Gas stopped flowing to the vehicle. Then the vehicle became inoperable. No warning light or alerts or sounds occurred before or after. It was a complete surprise.

The motor is randomly revving at braking so far only under 10 miles an hour. Yesterday it stalled twice on me and cut off braking under 10 miles an hour. I had to come to a complete stop while restarting the vehicle. Definitely has me worried if it happens on the highway or higher speeds.

While driving in traffic at 65mph, the engine stopped running, car went into neutral and there was no power for brakes or steering. I luckily made it to the side of the road. Vehicle was towed to my dealer ( Cardinal Buick GMC, Belleville, IL), where after 3 days they informed me that the engine was ruined, 2 main bearings were damaged and 4 of the 8 connecting rods were damaged. GM made the decision to replace the motor, but no time frame was given, I was told 2 to 3 months. The dealership did give a loaner car. My Yukon Denali was 1 year and 4 days old with 15, 882 miles on it.

On March 3, 2025, my 2024 GMC Yukon had a rattle/knock. The engine quit running and would not restart. The Yukon had to be towed to the dealership for diagnosis and repair. The dealer indicated that the engine required replacement due to metal shavings and bearing damage. The Yukon had 6450 miles when the failure occurred. The engine was replaced. This vehicle was purchased new in September 2024. This failure occurred while on the road at a traffic light and the Yukon could not be moved out of the traffic lane. Sheriff notified to provide scene safety while waiting for tow vehicle and during loading onto tow vehicle. No traffic accident occurred. There were no warning lamps on the dash or warnings on my phone app immediately prior to the failure.

The vehicle was towed to the local dealer, who diagnosed that the engine had failed and needed to be replaced. No further information was available. Additionally, the vehicle had previously experienced a loss of braking while driving with the cruise control activated. The contact stated that while driving at a slower speed, the vehicle lurched forward, striking a gate, and causing damage to the front bumper of the vehicle. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure. The contact was informed of the NHTSA Action Number: PE25001 (ENGINE, ENGINE AND ENGINE COOLING). The contact stated that the vehicle had experienced the failure listed in the recall.

Today while exiting an off ramp. I stopped for traffic signal. Truck immediately lost power and shifted to neutral. I placed my 4 ways 1. Put the people back in park restarted the ignition truck fired up. This is concerning as i've never had a vehicle with five thousand miles brand new shut off on me.

The contact's wife owns a 2024 GMC Yukon. The contact stated that while driving at 80 MPH, several warning lights flashed on the instrument panel as the engine shut off. The vehicle's speed abruptly decelerated as the contact was nearly hit by an 18-wheeler traveling close behind the vehicle. The contact managed to coast the vehicle as best as possible off to the shoulder of the highway. The vehicle was towed to a dealer and a diagnostic was performed which showed that the engine had failed. The contact stated that both he and his son suffered emotional trauma as a result of the sudden failure; however, neither has yet to seek medical treatment. The manufacturer was notified of the failure and the contact was offered a new engine despite the contact's request for a vehicle buyback. The contact stated that he did not feel safe driving the vehicle and feared for both his and his family's life as a result of the failure. The vehicle remained in the possession of the dealer and was not repaired. The failure mileage was approximately 22,000. The VIN was not available.

The vehicle one week after purchasing has had a tapping noise coming from engine and a rattling noise as well that you hear from the inside of vehicle. I have taken vehicle to two separate GM dealers. The first being where vehicle was purchased and they did not log in visit and basically said nothing could be done until engine breaks. The second dealer was only able to duplicate the rattling noise but had no loaner for me and advise would contact GM for next steps since a complaint has been filed. As of today nothing has been done. The second dealership also confirmed orange peel on paint and nothing either.

On February 14, 2025, my brakes went completely out in the school carline while picking up my youngest daughter. After the incident happened, I saw a light that read "Service ESC." This private elementary school is next-door to a private high school. There were students, teachers, and parents walking in this area at this time. I had to maneuver through this carline and away from faculty, students, and parents with no breaks. No individual was injured or killed but it could have been a very serious accident. I called GMC asking for help but was told through a chat line to bring the vehicle in for service. I was finally able to get my Yukon to the service department where after a few days it was determined my brakes failed and they were replaced. One day after I received the vehicle back from service, there was a horrible noise while driving but no lights showed on the dashboard, so it was returned to the same service department. They found metal shavings in my oil and I was told the lifters had collapsed and the engine failed. At this time, I have not heard from GMC and my vehicle is still in the service department.

The engine had a bearing fail causing the engine to knock and make loud noises. The engine has been replaced and is at GMC corporate investigation center. GMC installed another engine that is also doing the same thing 150 miles after it was replaced. My families safety was put at risk because the motor could have locked up or exploded with us in the car causing a crash or possible fatality. Yes the problem was found at the dealer and caused them to investigate which is when they found the failing bearing. Yes, GMC corporation has the failed components and identified the engine needs replaced. They have yet to comment on the second engine that needs replaced. There are no warning lights to identify this issue, The lack of notification from GMC could cause drivers to be hurt by not knowing their car is failing.
