ENGINE
While driving my 2023 Yukon Denali on [XXX] towards [XXX] , the check engine light came on and my truck stopped hard as if I jammed the brea but my foot was still on the gas and the RPM’s was moving. I was lucky that I was in the far right lane and there was no car behind me at the time or I would have caused an accident. I after 30 minutes waiting on the side of the road, I started up my 2023 Denali after letting it sit and put it in drive and drove 30 mph because I did not want to take the chance of my suv stopping abruptly again. I contacted a GMC Dealership and explained the situation and I told I am on my own and I would have to pay up to $10,000 for a engine and it would be no guarantee of being reimbursed by GM should I need a engine.

ELECTRICAL SYSTEM, ENGINE, VEHICLE SPEED CONTROL
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.

ENGINE
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.

ENGINE
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!

ENGINE
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 engine started making a rattling sound while on an interstate. The vehicle was able to make it to the next exit before it immediately lost power leaving it on the shoulder of a narrow road just past the exit ramp of the interstate. The vehicle was towed to a local GM dealership where technicians confirmed the engine was no good. This is the second engine that this vehicle has had replaced one at 18000 miles and one at 20000 miles.

SERVICE BRAKES, UNKNOWN OR OTHER
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.

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.

ENGINE
The complete engine on this vehicle was replaced by GM on 04/05/2024 at 24,069 miles. This was due to the known engine failures GM is having with the 6.2L engine. This is a well known and documented safety issue that GM is refusing to properly address. Vehicles with the 6.2L L87 engine are having complete engine failures while driving at highway speeds, which is a huge safety issue. I live in north Georgia where the roads are steep with sharp blind curves. I frequently cross steep mountains with high elevations that require frequent brake usage and constant steering through the sharp curves. I also drive on the interstate in Atlanta, GA where the posted speed limit is 70MPH. An engine failure in any of my driving circumstances is life threatening. As you know, when the engine fails you're braking and steering capabilities are greatly reduced. For example, if I was to experience an engine failure while driving across the mountain I would be unable to stop or get the vehicle off the road. Without being able to move, I could be stranded in a blind curve where I could be struck by another vehicle. I do not feel safe driving this vehicle and I'm in constant fear that it will have another engine failure like so many other 6.2L owners are experiencing. I'm morally unable to sell this vehicle to someone else due to the known engine failures. GM will not take responsibility and fix the issue or buy it back. So, I'm stuck with a $90,000 SUV that is unsafe to drive. Please continue to investigate this safety issue! You are saving lives by doing so. Thank you for everything you have done and are continuing to do. Please let me know if you need additional information or I can be of assistance.
