2023 GMC Yukon owner complaints

Took my Yukon in for L87 engine recall. Advisor informed me my engine failed. No symptoms, sounds or messages appeared.’

My vehicle was apart of the GM L87 recall. I took it to the dealership and it passed the recall and received the remedy which was an oil change. Now about 3 months later, I was driving in the highway at approximately 70 mph when the vehicle lost power and shifted to neutral. I had to attempt to veer off the highway with no acceleration. Upon getting it to the side of the highway, it wouldn’t do anything at all and had to be towed. The dealership has deemed it needs a new engine due to the failure the L87s are facing. We had no warning at all prior to the engine failure, and assumed that after passing a recall it had some degree of safety.

In April 2022, I purchased a brand-new 2022 Yukon Denali from Roberts-Robinson Chevrolet GMC in Excelsior Springs, MO. Shortly thereafter, the first engine failure occurred in October 2022. The vehicle was towed to GMC AutoNation in Golden, CO, where it remained until repairs were completed in January 2023. Soon after the vehicle was returned, the second engine failure occurred in February 2023. The vehicle was again towed to GMC AutoNation, and repairs were not completed until April 2023. At that time, given the repeated failures, I worked with GMC and Roberts-Robinson Chevrolet GMC to replace the vehicle entirely. I took delivery of a new 2023 GMC Yukon Denali as a resolution. On October 8, 2025, the engine on the 2023 Yukon Denali also failed, marking the third major engine failure I

I brought my 2023 Yukon in for the 6.2 GM inspection, and was told my engine was good, and the engine oil was changed. Approximately 3 weeks later the engine in the Yukon failed (seized) while I was towing my boat at 55mph, nearly causing an accident. I was able to pull the vehicle and boat to the side of the highway in a precarious location, which put me, my family and property in danger. There were no warning signs or messages on the dash, and no engine sounds. I believe GM's recall inspection and "preventative" oil change did nothing, and gave me a false sense that the truck was safe to tow with. I want to make sure the NHTSA is aware that the engine failed even after being screened with the recall. THIS FALSE REASURRANCE THAT THE TRUCK IS SAFE IS PUTTING THE PUBLIC AT R

The vehicle engine experienced a failure on the highway at very high speeds with no warnings leading up to this occurrence, same as many of the experiences of the customers with the 6.2L engines, which have been recalled for these defects. This GMC Yukon has the 5.3L engine, however, has the same defects as the 6.2L engine, excessive oil consumption and eventually engine failure. I am without a vehicle, with an extremely high car loan, and have to replace an engine in a two year old $75,000 vehicle. This should be covered by GM as it was a known issue and continues to be sold to unknowing customers. Furthermore, I am paying even more money to put another engine in this vehicle with the potential of having the same issues as the problem has not been corrected. This is deceptive and theft by

I was driving down 85 South bound at mile marker 16 the engine started messing up causing me and my family to be pushed over to the median. Once I was able to fight it over to the median it started smoking and i was afraid it was going to catch fire, so me and my family had to get out on the side of the interstate until help showed up and said it was safe to get back into the car. I had to use OnStar to get a tow truck, after the tow truck got there and i made it to the closest dealership to find out that the so called recall that the GM dealership fixed did not help the fact that the engine was messed up. So i tried to get a loaner or rental car for my family of 6 and they rented me a small SUV that I can not get all my kids into, I was told they did not have anything that bigger so now

The vehicle drove fine had no warning/ check engine lights. My girlfriend came up to a busy intersection and when she proceeded to cross the intersection the vehicles motor locked up stopping the vehicle in the middle of the intersection with traffic coming from both north and south direction. We had poor visibility due to blowing snow so she had to bail from the vehicle and stand on the side of the road so she would not be harmed if the vehicle was t boned. Vehicle stopped so hard and fast it threw her into the steering wheel. Was unable to get the vehicle restarted and could not get it to shift into neutral so vehicle blocked 1 lane of traffic completely and half of another lane until tow truck arrived to remove from road.

Drive shaft fell out of the vehicle while pulling out of a parking lot

GM has failed to resolve repeated issues on my vehicle (VIN: [XXX] ). I was never notified of any official buyback denial. GM Customer Assistance continues to avoid clarifying the status and refuses to provide documentation of the denial. This creates an unresolved safety and reliability concern. I need an investigation into the consistent mechanical defects paired with GM’s refusal to properly process my claim.

The contact owns a 2023 GMC Yukon. The contact stated that after starting the vehicle, the transmission shifter failed to shift from park. The contact stated that the "Braking System", Brake Pad Monitor, and Traction Control messages were displayed. The vehicle was towed to the local dealer. The cause of the failure was not yet determined. The vehicle was not repaired. The manufacturer was not yet contacted. The failure mileage was 44,871.

onstar telematic module failed. dealer stated it shorted internally. upon researching online this is a pretty common issue. this module is important to safety as it can detect & report crashes, help get first responders on scene in the event of a crash, etc. my vehicle was less than three years old and had an active onstar subscription at the time of failure.

The headrest in the 2nd and 3rd rows of the 2023 GMC Yukon are not adjustable or removable, reference page 39 of an owners manual. This is a major problem when installing car seats into the vehicle. Because of the design, the headrest tilt forward and do not allow car seats to properly sit against the back of the seats. This causes a gap between the back of the car seats and the seat back of the car. I have 4 kids and 3 different types of car seats. All of the car seat manuals say that for proper installation the car seats must seat flush with the seat back of the car. Well this cannot happen because of the design of the vehicle. Therefore I cannot properly install car seats of any type into this vehicle. I am not the only consumer with this issue as it is all over the internet as well. I

After GMC completed 4 recalls recently, my drivers side seat lumbar support started automatically inflating to the highest setting, as well as the shoulder support. I could not deflate the shoulder support at all, but could deflate the lumbar support, but had to do it every single time I got in the vehicle. After they did additional recalls about 30 days later, the issue got worse and often times I'm unable to deflate the lumbar support at all, making driving extremely uncomfortable and what I would deem slightly unsafe given how inflated the seat is. The fact that the 2nd set of recalls made this situation worse makes me suspect it's related to module updates as opposed to my particular seat. Now I am on the hook for a $1200 fix. 2 different GMC locations did the recalls.....I do no

While driving in approximately 10°F weather after the vehicle had been parked outside overnight during snowfall in Chicago, the vehicle displayed a warning that said “Do Not Drive — Maximum Speed 43 MPH.” At the same time, the brake pedal became extremely hard and the vehicle had significantly reduced braking ability, requiring much longer stopping distance. This occurred without any brake warning lights beforehand. After the vehicle warmed up and was restarted, the message eventually cleared but then there was a new transmission warning and the check engine light went on. After driving for a long commute, eventually all warnings disappeared. I personally know another 2023 Yukon owner who experienced the exact same message and braking loss under similarly cold conditions, which suggests

I bought my 2023 Yukon Denali Ultimate on or around August 9 2023, and I bought it brand new. On May 28 2024, around 30k miles, I was on the highway and could no longer accelerate. I luckily got myself into the breakdown lane before my car shut down & lost power, ended up being towed to the closest dealership. After 18 days at the dealership, I finally had my car back with a "new engine". Fast forward to November 25, 2025, I was on the highway again, my dash lit up telling me to "press start". As i figured that was not a good idea while driving in the fast lane on the highway, I did not. in a panic I got myself over to the breakdown lane where my car turned off. This time (November 2025), I still had power, but no car turnover. After 6 days of my car sitting at the dealership, they fina

Brand new vehicle, at about 5k miles the backup camera went out in April 2023. It is now December of 2023 and I have not had any sort of resolution. I have 3 children ages 2, 4 and 5 and it is very concerning for me and my wife to not have a backup camera especially at night.

Vehicle lost steering and brakes suddenly. Many errors on screen such as: Brake System Failure, ABS Failure, ESC Failure, Traction Control Failure, Maximum Vehicle Speed 43mph. Was able to slowly get home with no power assisted brakes. Did not drive it any more until it was taken to dealer 2 days later and the dealer could not replicate the errors. Dealer was able to see stored error codes; however, they could not verify any errors in any of the modules or computer. Dealer wants us to take it back and wife is scared to drive it due to no fixes or repairs. Loss of brakes and steering is NOT a situation to ask an owner to 'bring back when it happens again"

8/26/2025 I purchased the vehicle from Maguire in Syracuse, NY with open recalls. It is my understanding a dealership is required to have these fixed prior to selling a vehicle. I now have to drive 45 mins each way to get them fixed and miss additional 2 hours for wait time from work. Brakes could fail causing an accident.

Purchased 2023 GMC Yukon on August 21, 2025 and after starting the vehicle on October 2, 2025 the whole instrument panel cluster malfunctioned, failed to turn on, currently does not work and is available for inspection upon request. The instrument panel cluster is all black, it shows glitching flashing white lines on the right side of it therefore being unable to read the speedometer, fuel gauges, tire pressure, oil life, engine temperature, etc.. Prior to the instrument panel cluster malfunction, there were no warning indicators. Being unable to view the instrument cluster, makes the vehicle hazardous & risky to utilize for me and my family. This vehicle has not been confirmed or inspected at this time.
