2025 CHEVROLET TRAVERSE Forward Collision Avoidance Automatic Emergency Braking Problems

I turned my vehicle on and my brakes, ABS, traction control and anti collision lights all came on. Upon research this is a known problem in 2025 and a recall in 2024. It did in fact end up being the master cylinder and brake system that faulted

The vehicle has been brought to an authorized dealership for numerous service visits related to electrical system issues that ultimately affected the braking system. During one service visit, the vehicle was returned to me with multiple active dashboard warning lights illuminated related to the braking system, including Electronic Stability Control and Automatic Emergency Braking. I questioned the presence of these warning at pickup and was advised by the dealer that the vehicle was safe to drive and that the warnings would clear on their own. After driving the vehicle for a short period, I became uncomfortable continuing to operate it with brake-related warning lights still active and returned it to the dealer. Upon further diagnosis by a service technician, it was discovered that the vehicle has significant brake system defects requiring replacement of major components, including the brake control module and master cylinder. During diagnosis, the brakes locked and the...

While driving on the interstate, the anti-collision system activated when a car swerved in front of the vehicle. The vehicle stopped and resulted in a brake failure after that. All brake warning lights came on the dash, message stating brake failure and drive with caution and limited speed was displayed. Brakes were no longer working properly.

Emergency braking occurs at random, even if I'm the only vehicle / object on the roadway. This has been ongoing and has been to the dealership three times. It starts back up each time the vehicle gets an update. Adaptive cruise will brake hard due to false emergency braking, but does not always stop accelerating at the set point (has gone as high as 20 mph over the set point previously and brakes would not respond during). Vehicle was not starting and "press brake to start" warning was showing even though brake pedal was pressed. Brake master cylinder had to be replaced along with brake module. When picking the vehicle up afterward, warning light came while vehicle was warming up "service brake assist" and then shortly after the yellow-circled ABS dashlight came on. Dealership said this was a new problem and separate from the brake master cylinder and brake module.

2025 Traverse ABS brake system failed, and master cylinder broke at 12K. All of the safety features, Lane Departure, Forward Crash detection, blind spot, automatic braking system all stop working with no signs that it was failing! Extremely unsafe! Traverse are meant to be family vehicles, well with major functions failures this kind of problem is going be recipe for disaster if not recalled ASAP.

I started the vehicle to move it to a different place in my driveway and after putting it in reverse, it notified me that the ABS was not working. I could not stop the vehicle without pressing the brakes very hard and even then it was still rolling backward slowly. I quickly put the vehicle in park before the car rolled into my house.

My brakes, abs, front collision, esc light are on and dealership continue to try to fix and no luck. I have take 3 times in the last week with no luck. I need this fixed because I bought for safety features and now I have no vehicle to drive to work.

Brake assistance failure. Brakes failed! ESC SERVICE I was able to set it up for inspection Could of caused a accident hurting other people or hurting my family, I use this vehicle to transport my 2 babies Vehicle would not brake properly could have cause serious injuries For my vehicle not yet has not been inspected it was towed, from what I have heard from current Traverse owners they have experienced this same issue with even lower milage No warning lights no indications of failure just happend instant twice

We drove the car to the store and everything was fine we went in to shop. We came back out and I turned the car on and my dash board had lights on. My brake light will not turn off . My ABS light is on. My forward collision light is on .. I am getting a notice to service ESC, and a separate one saying service brake assist . I ran a onstar diagnostic and it came back everything is good. I have not brought it into the dealership yet for them to look at it I will be calling . I have multiple children and I was so scared my brakes were fulling going to give out on my 20 min drive home. I couldn’t imagine what would have happened we could have hurt someone else on the road and ourselves.

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.

The master cylinder and ABS braking system failed, rendering the vehicle inoperable and leaving my family stranded approximately 285 miles from home. This represents a serious safety defect, as the braking system malfunctioned while the vehicle was in operation. The dealership has confirmed the issue, and the vehicle has remained in their possession for over two weeks awaiting parts and repair. During the failure, multiple warning indicators illuminated, including the ABS, Service ESC, and brake system lights. Once the brake system engaged, I was unable to release it or drive the vehicle any further.

The service ESC, service brake assist came on. The ABS light, Brake light, crash light and lane assist light are all on. The dealership said it is the Brake Master Cylinder and module with fluid that is the problem and it is on national back order.

Started 09/17/25: While braking, a front-end clunk or thud occurs. Directly afterwards, a cluster of warning lights appeared including Brake, ABS, Collision avoidance/forward collision, and Stabile track stability control) Brake pedal is now inconsistent and soft. Every time the brakes are activated, the thud or clunk occurs. When I start the vehicle, I get warning messages of Service Brake Assist, Service ESC on the dash that I must acknowledge. Called Hendricks Chevy Columbia SC on 9/18/25. Told to bring into dealership on 9/19/25. Dealership attempted diagnosis but could not. They bled brakes and reset all warning lights. I drove car approx. 10 miles and symptoms reoccurred, including all warning lights and thud/clunk. Called Dealership again and told to bring into on 9/22/25. It is now 9/23/25 and they have not diagnosed it yet. I was assigned a loaner car for 5 days.

I rear ended a car on 3/12/25, and my automatic emergency braking system light was on at the time. When my car was returned to me, I set the braking system off, so the light was still on, but when I tried to turn the system back on in June, the light came on and told me I needed to get it serviced. As it wasn't a priority to have the automatic emergency braking system, I didn't take my car into the dealership until August 18, when 3 more dashboard indicators came on. The dealership stated they would be waiting on a part for my brakes, but it is on national backorder, with no ETA. It has been in the shop for over 4 weeks (it was dropped of 8/18, but lights came on 8/10).

The dashboard lights for the Braking, ABS, Electronic Control System, and Forward Collision Detection systems have remained illuminated. The vehicle cannot be driven due to the potential of brake failure.

Master cylinder needing replaced confirmed by dealer. ABS. Traction control forward emergency braking system service lights appear on dash and the systems are disabled saying service soon. Adaptive cruise control disabled super cruise disabled.

On Aug 15th, 2025 I went to pick up my children from school. As I picked up my child and turned the vehicle on to go pick up my second child, the car notified me on the dash board of 4 icons. Brake, ABS, traction and collision. Service ESC and Brake assist service needed. I was very concerned when I went to drive and when I gently eased into the brakes I could hear a small noise, every time I pressed the brakes. My second childs school is about 4 minutes away. I called Chevrolet dealership where I purchased it from in February, explained everything and they said i needed to take it in to a Chevrolet dealership near me. I called the nearest Chevy dealership and they said to bring it in the same day or the next day. Saturday Aug 16th, 2025 at 8am I was at the...

ABS and ESC and brake lights came on. Collision beeping and warning went out. Brake pedal vey late to respond to braking. This vehicle is unsafe. It has been sitting and the Chevy dealer for 2 weeks now with no information given to me about when it will be fixed. I call the dealer every other day and they just say that Chevy will be shipping parts. This is clearly a nation wide problem with this vehicle. I’ve read numerous articles online about people with the same problem and have contacted an attorney

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.

We were told we had a faulty master cylinder that needed to be replaced. The ABS, forward collision braking system, rear collision breaking system, and emergency brake were all at risk, which puts a significant risk to the passengers in the vehicle, including children. The problem was confirmed by the dealership with no information about timing of replacement since there is a national shortage of this part. Warning messages included ABS, BRAKE, forward collision, rear collision- lights came on several times. They appeared suddenly after turning on the car without incident. We tried turning off the car and letting it sit for long periods of time without resolution. The dealership initially flushed the brake line without resolution.

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.

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.

AFTER 4K MILES, MASTER BRAKE CYLINDER FAILED, WITH NO REPLACEMENT . EXPECTING 4-6 WEEK DELAYH

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...

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.
