2023 CHEVROLET TAHOE Service Brakes Problems

The car was parked totally normal, went into a store, then came out to start it and when it was put in drive every light on the dash came on and gave a warning for “brake system failure top speed 43 mph” “service traction control” “service esc” “service steering column lock” “service brake pad monitor” “trailer brakes disabled service required”. Shut the vehicle off and restarted with same results. Brakes were inoperable and almost hit the car parked in front of me. Let the car shut down for a couple hours came back and started it and now everything acts normal except there is a Check engine light. Haven’t read the codes yet but am making an appointment at the dealer for warranty work.

Vehicle suddenly lost breaking power while driving . The vehicle system shows Antilock Braking System issues. Losing Break power while driving has serious consequences

On 12/3/2025, I moved my car in the driveway at 11:15am EST without any issue. At 6pm EST, myself and 2 young daughters got into the car to head out an hour away. As I went to drive away, I stepped on the brake and the car did not immediately stop…the brakes failed and came to a rolling stop. At that moment all types of warning and lights lit up the dashboard. I placed the car in park exactly where it was in the driveway and left it. I also tried to select the Ebrake and it would not engage. I called the dealer first thing the next morning as that had been closed at the time it happened. I was told to bring it in and not to drive it so nobody in my car or else would be at risk. The car was towed at my expense to the dealer. When I got in touch with the dealer that afternoon to get a status. They advised the believe the BCM needed to be updated because it seem to not be communicating properly but wanted to keep it over night to retest it before they sent me home with it. Going to point out several things…thankfully I had not left my house, as I live on a mountain and should that have happened while descending it could have been catastrophic. No warning or anything that the brakes would fail! According to records it shows the did a recall update back in Feb 2025 regarding the BCM- however, how are we sure it truly was fixed or was defective. GM/Chevy needs to take accountability for this defect and safety hazard that could result in death. In reading forums, I am not the only one this has happened to

While driving my Tahoe on the highway at normal speeds approximately 65mph. I tried to exit freeway and my brakes were unresponsive. At this moment i began to allow the vehicle tto slow down on its own. I was able to safely exit the highway and the dealer ship was right off the exit. at low sppeeds i could push the brake pedal all the way down and acchieve some braking capability.

I was driving down [XXX] in LaPuente and every light on my dash lit up and I attempted to Exit freeway and my brakes would not work so I waited for car to slow down and luckily I was near by the Puente hills Chevrolet dealer. Also my steering wheel was very lose and it felt that I couldn’t steer well. I pulled into dealership and had to push my brakes all the way to the floor board just for Tahoe to stop. Dealer said that there was various communication codes which they said vehicle would have to stay due to safety issues. My vehicle has been at dealer for 3 days so far INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On multiple occasions my vehicle brakes with no warning. So much so I can hear the tires screech ever time. I brought to a dealership and they told me they can’t find the issue and no fault codes. This is understandable due to the fact that it doesn’t always happen. It’ll go so times a full day without happening. It mostly happens on the highway but happened today (24-July-2025) around 17:30. So needless to say this is a huge issue especially seeing I have three small children. Thank you so much for your time in this matter and I hope this finds you well.

Need new rotors and breaks purchased this vehicle with this issue and dealership or manufacturer want to fix this serious problem

Breaks keep making noises and all four tires need to be forced balanced dealership won’t fix the issues

I went to reverse and my brakes didn’t work, the error then came on dash “break system failure max speed 43 mph” I then had to drift into a parking lot to wait for my car to stop. Car dealership said they can’t find anything wrong, I have images showing the error

1st incident- Engine had a bad lifter and cam shaft with 46,000miles. When this happened I was going through a railroad crossing, if the failure was bad enough and locked the engine up I would have been stuck on the tracks with my family. This issue could cause the motor to lock up if the lifter or cam shaft had a more serious failure. Dealer confirmed the lifter and cam shaft were bad and replaced. the engine had a vibration 2 weeks before the failure but the dealership could not identify or duplicate the issue. Vehicle was in the shop for 35 days to repair. 2nd incident- Parking brake and brake system locked up and would not release until the vehicle was reset. Scheduled vehicle to be towed in and the brakes locked up again while loading the vehicle to tow. Dealer is still troubleshooting the issue after 5 days. Errors on screen "Forward Collision System unavailable, Brake system failure 43mph top speed, Service steering column lock, service traction control, Service ESC, Service Brake Pad Monitor" If this happened while on the highway it had the chance to cause a serious wreck.

While driving, without warning my brake system failed and vehicle did not stop when I applied my foot on the breaks. In addition to while driving up a steep incline the engine failed as I was actively applying my foot to the gas pedal causing vehicle to roll backwards. Most importantly i do not feel confident using this vehicle any further knowing that the brakes are Not operating as they should, risking my life and my children’s life is nonnegotiable. Someone help please.

On January 21, 2025 while  with my family in -15 degrees, the vehicle suddenly went into ABS lock. We were completely immobilized and unable to move the vehicle. The following warning lights illuminated on the dashboard:Antilock Braking System errorService Steering Column LockService Traction ControlBrake System Failure 43 MPH top speed. The vehicle was effectively locked, preventing us from driving or even reversing. This left me and my family stranded in a potentially hazardous situation with the freezing temperatures.

Bought new and there was a brake pad sensor message immediately that we took it to the dealer several times for and nothing was done other than clearing the code and giving it back. Was in accident 1/24 and it was found that there was a frayed/damaged wire in the break module and break pad sensor that I feel could have led to the accident

While driving this rental vehicle in traffic it shutdown and came to an abrupt halt. All lights on the dash were flashing, emergency hazard lights would not turn on. Attempted to restart vehicle with no result. After 2 minutes vehicle dash lights went off and hazard lights were able to be turned on. Vehicle then restarted. While pulling vehicle off the road, brakes were not responsive.
