Catastrophic brake system failure. When leaving my home in baltimore county, MD, at approx. 10:00am on February 3rd, my vehicle started up normally. As I descended down a hill in our neighborhood the brake system failed and the vehicle would not stop. By standing on the brake pedal I slowed enough to put the vehicle in park as I entered an intersection with the main road. I have since learned this is the 3rd GMC Yukon (years 2023-2024) that has had the same brake failure in 24 hours in our community.
While driving approximately 63 mph on a busy roadway, my 2023 GMC Yukon experienced a sudden failure of the brake system, including loss of normal braking capability along with failures of the electronic stability control (esc) and abs systems. The vehicle displayed warning messages stating “brake system failure” and “service esc” and entered a reduced-speed mode. Prior to this incident, there were no warning lights, messages, or symptoms indicating a problem. During the failure, the brakes became largely unresponsive, placing me, my two minor children who were passengers in the vehicle, and surrounding motorists at serious risk of a high-speed collision. After extended deceleration, a minimal amount of braking power partially returned, allowing the vehicle to eventually come to a stop. The vehicle has not yet been inspected by a dealer, manufacturer, police, or insurance representatives, and the issue has not yet been reproduced or confirmed by a service center. The vehicle remains available for inspection upon request and has not been repaired. This incident occurred without prior warning and involved a sudden and dangerous loss of braking capability at highway speed.
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 • 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.
Vehicle lost steering and brakes suddenly. Many errors on screen such 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".
The contact owns a 2023 GMC Yukon xl. The contact stated that while driving approximately 25 mph and depressing the brake pedal, the vehicle failed to respond. Several unknown warning lights were illuminated, and the message "you have no brakes - do not drive over 40 mph" was displayed. The contact allowed the vehicle to roll to a stop. The contact turned off and restarted the vehicle, but the failure persisted. The contact parked the vehicle. The contact stated that the failure had not caused an accident because the contact was driving early in the morning and there was less traffic on the road. The contact stated that her husband started the vehicle later in the day, and the warning lights were off. The vehicle was driven to the dealer to be diagnosed. The dealer diagnosed the vehicle and informed the contact that several dtcs were retrieved, including a dtc for brake failure; however, the flow chart from the manufacturer instructed to first replace the battery and then reset the codes. The dealer replaced the battery, reset the codes and test-drove the vehicle. The vehicle was repaired and returned to the contact. The manufacturer was notified of the failure and supported the dealer's assessment. The failure mileage was approximately 70,000.

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.

Urgent appeal for investigation into braking capacity discrepancy dear national highway traffic safety administration (NHTSA),I am reaching out to bring a critical matter to your attention regarding the braking capacity of my diesel vehicle, which has not been adequately addressed despite multiple notifications to the service center. The primary concern I wish to highlight is the inadequate braking capacity of my diesel vehicle, which poses a significant safety risk. This concern is especially troubling when compared to my similar gas-fueled vehicle from the same manufacturer, which exhibits notably superior braking performance. After discussing this matter with the service center, their response was that the braking performance is considered normal for my diesel vehicle. However, the evident disparity in braking effectiveness between my diesel vehicle and the gas-fueled one suggests otherwise. This difference is particularly concerning given that both vehicles utilize the same brake system, despite the diesel vehicle's higher weight. In light of these circumstances, I urgently request NHTSA's intervention to investigate this matter promptly. The inadequate braking capacity of my diesel vehicle presents a tangible risk to road safety, affecting not only myself but potentially all drivers on the road. It is crucial that corrective measures are taken swiftly to address this issue and ensure the safety of all drivers. Your prompt attention to this matter is greatly appreciated. Thank you for your immediate action.
