2023 GMC YUKON Complaints

While driving the 370 miles from Fairbanks to Anchorage with our family and dogs, our vehicle shut down completely with no warning. The drive is through a very remote section of Alaska. While passing a slower vehicle, our Yukon completely shut down, to include the all controls including the dash and lights. We were unable to complete the pass, leaving us in direct line with on coming traffic with no ability to speed up to get around the other vehicle. The other vehicle, not knowing we had lost all power, continued driving the same speed and eventually we were able to get back into the proper lane and coast to a stop on the side of the 2 lane highway. The vehicle would not start and with the temperatures outside at 12 degrees it got chilly fast. Luckily we travel with all of our winter gear. Had this incident happened on one of the many steep descents or curves with snow and ice, the outcome could have been disastrous. My wife has decided that if the vehicle does get fixed, she does not feel safe driving home in it. Reading online forums show that this is a very common occurrence and individuals are looking into a class action lawsuit against GM due to the safety issues associated with this. An individual passing by had a code reader and tried to reset the ECM but could not. I will include the report.

On [XXX], while driving on the [XXX] Highway with my family, the vehicle automatically shifted into neutral and I lost control of the accelerator pedal. I safely changed lanes and pulled over to the shoulder. Once in park, the vehicle never started again. We were stranded on the side of the road until my husband and a tow truck returned to collect my family and tow the vehicle to the Fairbanks dealership. The engine was diagnosed as an engine failure requiring complete engine replacement. We are a military family and were on orders to move our household on [XXX]. We did not have any other option but to trade in the vehicle and purchase a new one. Had I been driving on a road that did not have a shoulder or the traffic too congested to safely change lanes, my family could have been in significant danger for a motor vehicle accident.

January 16, 2025: Driving down the interstate near Atlanta Ga going 75 MPH, our 2023 Yukon Denali with 28,585 miles on it, abruptly started gearing down. The vehicle would not accelerate, it was coming to a stop on its on. Traffic was very heavy and it was a very scary situation. After managing to get the vehicle barely off the interstate it totally lost power and would not start. The vehicle was towed to the local GMC Dealership and within 30 minutes they told us the engine had locked up. We had to get a rental car to continue our trip and haven’t had much luck, so far, getting reimbursed. As of today February 6th, GMC cannot give us an estimated repair date as our engine is on back order!

At 9,900 miles my safety camera system failed which disabled the cruise control and all safety features that used the camera. Car was out of service for nearly two weeks and subsequently fixed by the dealer under warranty at no charge. At 11,300 miles I was driving on an interstate highway in the left lane at rush hour, without warning the car stopped accelerating the car shifted into neutral and totally lost power. It was a very dangerous situation with me in the left lane in heavy traffic. I am a skillful driver and thankfully I was able to make it off the travel lanes on the highway. The temperature was 18 degrees at the time and I had to wait outside for a tow truck. The engine seized without warning or noise and this presents a severe danger to the driver of the vehicle and other vehicles on the highway. There was a substantial possibility that other vehicles could not avoid me as I was exiting the travel lanes. There was also a substantial possibility that the vehicle would simply be in the travel lane stopped on a divided highway.

Engine failed on highway while my wife was driving with 3 kids aged 5 and under. Had to pull over on shoulder. Called GMC roadside and they said they would be there in 2 hours. Then a police officer came by, told her she was in too dangerous of a spot and that the police would be towing the vehicle in 20 minutes if she didn't move it. Police then towed the car while my wife, on the shoulder of a busy highway, had to frantically move the 3 kids and their car seats into a friends car. Got car towed to GMC and they did a full engine replacement. No warning lights, no signs of malfunction, and car had about 4k miles on it at the time.

The contact owns a 2023 GMC Yukon. The contact stated while driving at approximately 65 MPH, there was an abnormal clicking sound from the engine compartment. The contact stated that there were no warning lights illuminated. The contact arrived at the destination and checked under the engine compartment and saw engine oil covering the undercarriage of the vehicle.

Driving at a slow rate of speed turning onto my road the engine started making a loud knocking noise, I could actually feel the knocking through the steering wheel and seat. Loss of power due to the problem. No warning before the issue started. Had to have vehicle towed to my local dealer. They are currently looking into the problem.

The engine failure was confirmed by dealer. My wife and I were traveling on I-74 at approximately 72 mph when the truck began to jerk slightly. This continued for about a mile, prompting me to ask if she felt it too. Suddenly, the truck lost power while we were driving on a two-lane interstate, putting our safety at risk. Fortunately, we were close enough to an exit and managed to coast to a nearby restaurant. Thankfully, it was not during peak business hours, and no vehicles were directly behind us at the time. Given the heavy semi-truck traffic on this stretch of interstate, the situation could have been significantly more dangerous.
