While driving our 2025 Chevrolet Traverse with 9450 miles at 45 MPH, it suddenly came to a complete stop and would not advance. Eventually after restarting the vehicle it would drive again, but the ABS, collision avoidance, traction control, and emergency braking was disabled. We learned that the "master brake cylinder" failed. This requires a repair and the parts are backordered. Furthermore we learned this is a known common issue and there is a service warning for the 2024 Traverse and there is now a class action lawsuit. It apparently is also common on the 2025 traverse. This is a potentially dangerous situation that apparently is common and should prompt an immediate recall and replacement with a new and redesigned part. There are numerous reports of similar incidents and per the dealer this is a common repair.

When my new vehicle hit 4k miles, the dash started to show alerts for "Service ESC" and "Service Break Assist". As well as those alerts, there were additional notification lights for "Brake", "ABS", "Electronic Stability Control (ESC)/Traction Control", and "Forward Collision Alert (FCA)". After some research, I was worried to drive my car incase the breaks would not work properly. So I discontinued to used my car with my 2 young children. The Chevy dealership has confirmed it's the back master cylinder that needs to be replaced. From my research, this is a common issue happening and a roll over issue from the 2024 models.

Brake master cylinder ECU failed. Illuminated warning lights for BRAKE, FRONT END COLLISION AVOIDANCE, ABS, and ELECTRONIC STABILITY CONTROL. Took the vehicle to dealership and was told about the part failure. They advised that there was no ETA on parts that are on backorder. The codes were removed and the warning lights went off, but came back on the next day. I was told that the vehicle was drivable, but they could not guarantee my safety. The dealership had no loaners so I had no choice but to drive the vehicle home.

I started my Traverse and the brake light, forward collision alert, brake assist, stability control lights came on. The warning messages to service ESC, and service brake assist also came on. I have 2182 miles on my vehicle. No warning of anything wrong before this happened. It is available for inspection. It was towed to the closest dealership who determined the master cylinder needed replacing. I did not drive it due to warnings the brake systems were not functioning properly. Could have caused a wreck if they did not work. It has since been towed to the dealership it was purchased at awaiting their diagnosis. The first dealership said the master cylinder is on backorder with no ETA.

As I was driving my 2025 Traverse Z71, at 2180 miles, different lights popped up on the dashboard. I was backing out of my garage when it happened. Lights were ABS, BRAKE, Electronic Stability Control, and pre-collision warning light. Also notifications for Service Brake Assist and Service ESC also came on. The dealer had me drive it to their shop 25 miles away. After inspection, the Chevrolet service department said it was unsafe to drive my Traverse. The part they needed to replace was the Master Cylinder/Brake System Control Module. Unfortunately the part was on backorder and they did not have a loaner I could borrow. I turned in my vehicle Wednesday, June 25, 2025. I got my Traverse back Thursday, July 24, 2025. It was very close to 30 days and I would have followed guidelines for lemon law in state of WI. When I picked up the vehicle, there were several other Traverses waiting on the same part. As of now July, 30th, vehicle is in working order.
