2023 GMC Yukon Driver assistance Problems

The brake system control module, engine control module, and vehicle stability control system have repeatedly failed across 24 months and 9 repair attempts at two authorized GMC dealerships in Tennessee. As of March 17, 2026 the vehicle has 27 active diagnostic fault codes including U160F and U1610 (brake system control module lost communication on both CAN buses), U1611 (engine control module lost communication), and C2A0A (vehicle stability control disabling inhibited). All components are available for inspection at Beaman GMC in Antioch, Tennessee where the vehicle currently remains in an undrivable condition. Safety risk: Vehicle has stalled on the highway with my family including young children in the car. Brakes have randomly engaged over 100 times with nothing around and also failed to engage when needed. Stability control is disabled. These are active safety failures confirmed by GMC's own diagnostic scans. The problems have been confirmed by both Darrell Waltrip GMC and Beaman GMC across 9 visits. GMC's own Technical Assistance Center (Case XXX) was involved and could not resolve the defects. The vehicle was returned with more active codes than at drop-off after 57 consecutive days in GMC custody. Two unresolved GMC safety recalls are open on this vehicle — L87 engine loss of propulsion (N252494003) and brake fluid leak detection failure — directly related to the reported defects. Warning codes have been present and documented since October 2023 beginning at 1,381 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle experienced a malfunction associated with a failed Over-The-Air (OTA) software update affecting electronic control modules. The (ECM), (BCM), and related electronic systems appeared to lose stability during operation. The vehicle attempted to reboot while being driven and displayed multiple system warnings. The vehicle is currently at the dealership and is available for inspection upon request. How was your safety or the safety of others put at risk?While driving, the vehicle began malfunctioning and attempting system reboots. The dashboard flickered, warning lights, and the vehicle exhibited unstable behavior. During a prior event, the vehicle experienced unintended acceleration and abrupt deceleration. This created a risk of loss of vehicle control, particularly in traffic. I have small children in this vehicle, and the unpredictable electronic behavior while in motion posed a significant safety concern. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealership confirmed that a previous event was caused by a failed OTA software update. The vehicle has since malfunctioned again while driving and has been taken back to the dealership for further inspection. The dealership has acknowledged module instability and opened a TAK case with the manufacturer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by GMC1 dealership. A case has been opened with GM Customer Care. No police or insurance reports. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? 9 days prior to the first major malfunction, the check engine light illuminate. On April 1, the check engine light re-appeared and the vehicle attempted to reboot again while driving.

We are located in Henderson, NV and we were driving on the freeway in a construction zone with no emergency lanes when the vehicle lost all power to the engine going the speed limit. The engine had seized up which is a known problem with the 6.2L GMC motors. We have done all the recalls recommended by the manufacturer. The engine seizing, locking up , put our family in danger . We were luckily enough to be close to an offramp where people in other vehicles barley let us over so we can pull off the road or we would of been stuck in the middle of the highway with cars flying by us with little kids in the car. This is unacceptable and as much as this happening and GMC not fixing the issues, people are going to get hurt or killed. IT IS A HUGE SAFETY CONCERN! . ThIS is a known issue with these motors and problems and GMC is putting bandaids on the situations when lives are in danger. Our truck is a 2023 GMC Yukon Denali with only 53k miles on it

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"

Incident

Dec 4, 2025

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 this may be a broader safety issue affecting this model year. Because this involved a sudden safety-system activation combined with temporary brake loss, there was a real risk of being unable to stop the vehicle safely or avoid a collision. My vehicle is within the year range of GM’s brake-system software recall N242447990 (eBCM brake fluid loss detection issue), and it is unclear whether my case is related, but the symptoms point to a potential systemic braking or electronic brake control problem in the 2023 Yukon. This issue warrants investigation due to the combination of: • Hard brake pedal • Reduced braking performance • Speed-limiting safety warning • No prior diagnostic warning • Occurrence in very cold temperatures A sudden loss of braking ability is a serious safety defect.

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 finally had the time to look at the issue. The Dealership did the recall and got the car started, but the car still had a funny sound that the mechanics didn’t like , so they were waiting to hear back from higher up people as to what to do. Today I got the call that they will be replacing the engine for a second time and I will not have my car back until the first week of January. There were zero warning lamps, Zero Symptoms, nothing. I am Lucky that the Highway wasn’t too busy in that moment, because there were many 18 wheelers on the road that day, and one almost swerved into my car missing it by about two feet while my dead car sat in the breakdown lane. Yes I called the state police, Yes one trooper kindly pulled behind me to ask if I was safe and had a tow on the way. But that truck that nearly plowed into my dead car could have prevented me from picking my [XXX] [XXX] [XXX] daughters up from school, forever . To say that I am disgusted with GM, is an understatement. They’re risking lives. I should not fear for my life, my kids lives in a new, "safe" vehicle. No pun intended, but this is highway robbery.

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.

I am experiencing ongoing issues with the infotainment system in my vehicle, which has remained unresolved despite multiple service visits. The system frequently blacks out, reboots while driving, and fails to function entirely at times, for days at a time. This is more than an inconvenience — it presents several serious safety concerns, including: •Loss of the rearview camera and parking assist features, making reversing hazardous. •Inability to access hands-free calling and navigation, increasing the risk of driver distraction and noncompliance with hands-free driving laws. •Disruption of access to climate controls and safety alerts that are routed through the infotainment system. •Frequent system crashes while driving, which divert my attention from the road. These issues compromise both the safety and usability of the vehicle, and I am requesting immediate action to resolve the problem under warranty.

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.

The vehicle was crawling to a stop in preparation to park in front of my garage door. When I move my hand across the steering wheel, my hand must have come in contact with the toggle/scroll for the “resume speed” function of the cruise control. The vehicle abruptly began accelerating towards my house. I was able to press the brake pedal to deactivate and stop the vehicle safely. I note that in the past week, perhaps even two, the cruise control has not been used. The vehicle is driven 2-4 trips a day.

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.
