August 6, 2025 I was driving and it started to rain and there was a little rain on the road and my vehicle appeared to be hydroplaning. I had never experienced that before and it scared me to the point that I reduced my speed significantly. I arrived at my destination and was there for about three hours and when I started my 2025 Chevrolet Traverse I had 4 lights come on my dashboard along with a warning chime. The lights were the BRAKE LIGHT, ABS LIGHT, FORWARD COLLISION ASSIST LIGHT AND TRACTION CONTROL LIGHT; and a Service ESC and Service Brake Assist message popped up in separate boxes from the lights themselves. I turned off my Traverse and hoped it was some fluke thing and again the same lights came on and same messages. I drove my vehicle home cautiously and parked it. I called the dealer I purchased it from the following morning and was given a service appointment 11 days out and I stated that was unacceptable since I was not sure the vehicle was safe to drive from everything I was reading online. The service dept stated that they could place it on a machine if I stopped into the dealership and let me know if was safe to drive. My husband drove it to the dealership 25 miles away and wasn't happy with the service department and spoke to a manager and he stated they would look at my vehicle the following day and gave me a loaner. My husband advised the manager that everything I had been reading pointed to an issue with the master brake cylinder and the parts are on backorder and the manager said he hadn't heard of any issues with them. I received a call 4 days later after asking the status of my new car repeatedly and was told that it is the master brake cylinder and a couple of the parts are on backorder and they don't know when they will arrive; could be a week, two or a month. I am extremely concerned about the seriousness of this issue and the lack of parts to repair the vehicle. As I stated, there are multiple incidents on google over this same issue.
8/4/25 Vehicle was pulling from side road to main highway when lights and warnings came on dash cluster. brakes were very soft and not very responsive, car was slowed down on its own. Was able to pull into a driveway and take photos of some of the messages. One said service traction control, one said service ASC, and one said ‘brake assist fail, press hard to brake, speed reduced. After restarting car all was normal. 8/11/25. Sitting in some morning traffic and all the same messages came up and brakes were soft again. Was able to keep some distance between myself and other cars until I could get off the road. Immediately made an appointment for dealership service. After restarting car, all was normal again. Took car to dealership at appointed time and they kept it for a week and only did test drives to try and recreate problem. When they couldn’t they returned the vehicle to me with nothing done but clearing codes and checking for updates. This is unacceptable. I am hauling my precious grandchildren in a brand new vehicle that could have a braking failure at any time. Obviously braking failures can cost lives. There is a GM service bulletin for this exact problem in December 2024 (N242482170) requesting the master cylinder should be replaced. This service bulletin doesn’t extend to the 2025 Traverse model and it should as the problems are exactly the same. I hope this can be resolved. I’m very uneasy driving now and just keep wondering when this will happen again and how bad it could be.
Car with only 3900 miles brand new after 3 months the braking system, collision system, parking assist, ABS and brake lights appeared on dashboard, at the dealer since 07/14/2025, I was suggested not to drive the car. Same day called GM customer service and opened a case, the dealer gives me a rental car to use until the repair is finished. At the end of the same week I called again GM customer service asking about news and the parts was back ordered, they told me to wait 5 business days for a possible repurchase or for any updates for parts. Today 07/31/2025 I called again GM and they said that the parts were shipped but they didn’t had the tracking number, I called my dealer and the parts are in back order without eta.
Brake light, ABS light, Forward collision light and Traction control light all come on when the car was started. Had to be towed to Woody Folsom dealership in Baxley, GA and is currently still there. Was told it was the brake master cyclinder and it is on nationwide backorder. The part came in this week and they put it in and could not get the car to program. They are waiting for another brake master cyclinder to arrive. So I am at 8 weeks of the car being down and in service at the dealership with no estimated date of when and if it can be fixed. I have received Onstar notifications that says A critical issue with the engine and transmission system in your 2025 Chevrolet Traverse has been detected. The battery in your 2025 Chevrolet Traverse is critically low.
