Automatic Emergency Braking problems of the 2023 Chevrolet Tahoe

The following notifications showed up on my dashboard as my breaks failed me! I was going down a hill and hit the breaks and they would not work, I could not stop the car! - service break pads - forward collision system unavailable - break system failure - service traction control - service esc - check engine light on this is the second time this has happened in 4 weeks. We just got it back from getting it “fixed” one month ago. One of the scariest experiences, losing breaks!.

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.

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.
