This Problem Across All Years
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"

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.

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.

1. First incident While driving, the brakes failed and the entire infotainment/tablet system locked up. This presented a severe safety risk to my family and others on the road. The vehicle had to be towed to DEALER where I was told that “no problems were found.” I documented the incident with photos and videos showing the warning messages and system status. 2. Second incident Approximately one week ago, after shutting off the vehicle, a “steering wheel lock” warning appeared and the truck became completely disabled. Even with jumper cables, it would not start. The vehicle had to be flatbed towed to DEALER. I again documented the incident with photos and videos showing the warnings.

My wife was driving in the vehicle with our two (2) infants on Dixie Hwy in Boca Raton, FL when the breaks suddenly stopped working. Fortunately, there was not a lot of traffic on the road at this time and eventually the vehicle slowed down and no one was injured. No warning lights came on. Once the car came to a complete stop my wife turned off the vehicle and started it back up; still no warning lights or anything. My wife drove a little further to get to a safer location (not in the middle of the road), unfortunately the car then completely stopped working and my wife was still stuck in the middle of the road...eventually a police officer (crash inspector) came to the scene and the car was towed to the dealership for repairs.

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.
