While driving the automatic brake assist failure light came on. I was unable to stop at a very busy intersection and was forced into traffic even though I had a red light. The parking brake, engine light, and light came on.
2025 Chevrolet Traverse brakes complaints
Page 5 of 5: complaints 101 to 119 of 119, newest first, as owners wrote them.
Warning codes - Service Brake Assist, Service Electronic Stability Control (ESC), Forward Collision system unavailable. Brake pedal felt different with an associated clunk noise. Brake Fluid believed to have been leaking in garage. Dealer diagnosis as Master Brake Cylinder failure. No parts available/no ETA available. Car is 5 months old and under 5,000 miles on the odometer.
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.
Our 2025 Chevrolet Traverse experienced a brake system failure on July 17th. We took the vehicle into the shop with the following errors on the screen: Service brake assist Service ESC Forward collision system unavailable My wife and children were in the car when the incident occurred. We have a 20 minute drive, through traffic, to the nearest dealership. At any point, the brakes could have completely failed. The problem is active as the car still remains at the dealership, Alan Jay Chevrolet of Wauchula. The vehicle has not been inspected by the manufacturer, but by the qualified service staff at the dealership.
Master Cylinder failure after less than 3 months of ownership and only 3,891 Miles. Multiple warnings lights related to brakes appeared when the car was started. GM already had a TSB for the 2024 Traverse but has not come out to say 2025 models are impacted yet. Multiple reports of people that do have the issue are waiting weeks for a replacement part because GM is not able to source them. Seems that there is a known issue but GM is just waiting for something to happen due to the lack of parts. Given it's the brakes could result is serious injury due to GMs negligence.
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.
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.
Began driving warning lights for brakes, abs, traction control, and forward collision on. Brakes then locked up. Pulled over and full lost brake compression. Could have caused an accident if on the highway. Waiting on tow truck to take to the dealership for repair.
The master brake cylinder failed around the 1600-mile mark. It seems to be occurring on 2025 Chevrolet Traverse and Buick Enclave models. GM has no ETA on replacement parts. I took it to a nearby dealer service center (Dave Kirk Chevrolet in Crossville, TN), and they diagnosed the issue. I took it to a second dealer (Murfreesboro Chevrolet Buick GMC in TN), and they diagnosed the same issue. The vehicle is now sitting in the dealer's lot with no ETA on a replacement part.
Purchased new 25 Traverse. Driving from AR to OK, stopped at a store, parked car. Upon returning to car, start ignition and red "BRAKE" light illuminated as well as ABS, Traction control and forward collision icons all lit. "Service brake assist, service esc, rear auto brake and park assist unavailable" warnings all show on the dash. Vehicle had 2747 miles at time this occurred. Systems check on dash showed all tires not registering on the vehicle and the vehicle icon illuminated orange. Vehicle needed to "relearn sensors." Vehicle has several clicking noises in the dash after shutting off. Vehicle brake pedal clicks when depressed at low speeds (as in driving in a parking lot) These noises and issues were not occurring prior to this vehicle stopping at the 2747 miles. Vehicle is unsafe to drive as this is the main stopping system, we were 300 plus miles from home when this happened.
On 6/18/25 vehicle started displaying "Service braking system" and "service electronic stability control" warnings along with warning chimes and various malfunction indicator lights. Malfunction Indicator Lights included service brakes, ABS, and ESC. Vehicle taken to dealer service department on 6/18. Service department has replaced the battery and brake assist module, but the problem persists. GM says to replace the brake master cylinder, but no parts are available. Dealer has impounded the car as a safety concern and has provided a loaner vehicle. Because this involves the service brakes it is a safety concern.
Had lights on my dashboard when I turned it on the morning of 6/1/25. Brake light, traction, ABS, and forward collision. Cruise control also stopped working. Brake module needs to be replaced.
While driving the vehicle a brake assist and service ESC fault occurred. It flashed on the dashboard. The issue just appeared with no prior warning. This made the brakes very difficult to engage and control. I was driving 50+ MPH down a congested road and almost collided with vehicles in front of me stopping for a traffic light. I had my wife and two small children in the vehicle with me. I made it to a place of business and turned the vehicle off. It would not restart and had no power. It was towed to the dealership. The issue has occurred on two other occasions. Once about a month prior. The vehicle was able to restart and the fault was gone. The first time this happened was right after I purchased the vehicle. It had 500 miles on it. It was serviced by the dealership who replaced the master brake cylinder. The vehicle does not feel safe to drive due to the issue. You loose control of the brakes with no prior warning.
The contact owns a 2025 Chevrolet Traverse. The contact stated that while driving 70 MPH during a road trip, the ABS warning light illuminated upon depressing the brake pedal. The contact stated that the messages "Control Module Performance Warning" and "Forward Collision Alert System" were displayed. The contact continued driving, and the brake pedal and steering wheel became stiff. The vehicle was pulled over to the side of the road and restarted. The message "Do Not Drive the Vehicle over 62 MPH" was displayed. The vehicle was taken to a dealer, where it was partially diagnosed that the brake plunger motor temperature was too high, and there was a braking performance failure. The dealer reset unknown sensors, and the contact and his family drove to the destination. The vehicle was taken to another dealer, where it was diagnosed that the brake master cylinder had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 913.
Master cylinder failure per Chevy shop. Dash board ESC alert with immediate service needed. No obvious symptoms prior to warning dash alerts. part is delayed no ETA
On June 10th I drove my vehicle to work downtown Cleveland (no issues). Got home around 1 pm and had to leave at 3:30 to get my daughter from school. As I got in my vehicle I started to go in reverse and received all of those notifications and my brakes went completely out and I had to slam it to the floor to stop it was so scary and I thank god I wasn’t on the road or with my children!! I called the dealership the next day and they finally had my vehicle towed on the 12th of June. Once my car was there “the error messages disappeared and it was fine”. I did not feel safe taking the car back so they kept it another day and had the technician driving it around, still nothing until he washed the vehicle then it happened. After doing a ton of my own research others have stated the 2025 traverse has the same issue and they had to get the master cylinder replaced so I mentioned this to them at the dealership. The lady called me back and said I was right. They put me through Hertz for a rental and I found out today they didn’t even order the part until the 20th. This is very frightening and should be a recall immediately! I can’t imagine if I was driving 70 mph and this happened I could’ve died or killed someone else!
Car has 1200 miles on it. Turned on and dash lit up with warnings. Took to dealer who confirmed the master cylinder is bad & must be replaced. Worse than that—it is back ordered and I am currently given an estimate of July for the replacement part. Hadn’t even made the first payment on my brand new vehicle before it had to be taken in and now I am without it for an unforeseen amount of time.
I JUST bought my car brand new 3 weeks ago. Yesterday as I was driving, my whole brake system just went out. About 6 lights came on the dash and maintenance was flashing. I got it to the nearest Chevy dealer and the Master Cylinder is bad. On A BRAND NEW CAR. A cylinder should last the lifetime of a car…not 3 weeks. The car is not drivable and I am told the parts are back ordered until the end of July. What if my children were in the car when this happened or if I was going 60 mph?? Unacceptable and someone needs to be aware of this!
Purchased car Tuesday, Thursday night upon pressing the start button all power went out on car. Driving to dealership to have car looked at vehicle shutoff completely at traffic light. Vehicle restarted then two miles from dealership car had multiple warnings and brakes completely went out. Managed to get car off the road safely, currently awaiting tow.
