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.

Vehicle leaked a large amount of transmission fluid because it had loose pump bolts per a GM/Chevy bulletin. The vehicle has shifting problems and vibration issues. The vehicle has done in multiple instances phantom braking. It has happened while parking and while exiting praking spaces and once on the Florida state road 924. Driver was able to maintain control of the wheel and avoid a collision.
On July 16, 2025, with 4,514 miles on the odometer, the dashboard displayed warning messages for “Service ECS” and “Service Brake Assist,” along with illuminated indicators for BRAKE, ABS, and Traction Control. At 4,598 miles, the master cylinder was replaced. However, after installing a new brake master cylinder, power brake booster, and Electronic Brake Control Module, the brakes failed. As a result, an independent certified dealer had to reinstall all components to address the issue.
Brake booster failure, master brake cylinder failure
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.
I was driving down the road with my 4 year old son in the back and I went to stop at a stop sign and my car immediately lost brakes, the brakes went down to the floorboard with almost little to no stopping of my car. Then I had 3 warnings on my dashboard I can send pictures of them, my check engine light came on, my abs light came on and my traction control light came on. Very scary and something needs to be done about this
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 2025 Chevy Traverse was purchased on 10/27/25 - new. On the morning of 10/31/25, several lights came on for service such as the brake, ABS, traction control and forward Collison. Through a quick google search, saw there are many issues with the master cylinder leading to brake issues. At this time, the car only has 535 miles. Prior to this incident, the car had no evident issues. I contacted my local dealership to set up an appointment to have the issue assessed and fixed. The appointment is scheduled for 11/5/25. I will not be able to drive the car in the mean time, as it poses a safety concern (brake failure) to my family and myself.
I started my car last Sunday afternoon (10/26/25) and it began to alert me with tones and flashed on my dashboard "Service Brake Assist" and "Service ESC". Prior to that I drove it earlier that morning and it was seemingly working fine. Took it to the dealership the next evening (Monday, 10/27/25)for them to look at the following day (Tuesday, 10/28/25) and was told they were still looking into it. They just contacted me today (Wednesday, 10/29/25) that it is the brake master cylinder that had failed and that I should not drive it and they offered me a rental car.
front collision system failed. ABS and traction control are now failing. My breaks gave out Yes No The failure happened the day the warning lights came on - 10/26/2025
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.
My traverse breaks gave out while going to pick my kids from school. I cannot safely drive my vehicle. Master break cylinder needs replacement,
a week after purchase with less than 300 miles and 5 days the ABS, Trac Control, ESC, lights came on.. The same TSB known to the 2024 Chev Traverse are happening to my car, the same parts suggested in that TSB are what I am being told is being replaced in mine... The TSB I found includes 2025 Buick Enclave and 2024 Traverse. Seems the 2025 is probably having the same issue. The brakes did not fail but the lights remained on, the sealer advised the car was unsafe to operate until the parts were replaced. I am in a loaner car under factory warranty of course but I think the TSB should be expanded to include 2025 Traverse as well.
Service ESC & Brake Assist lights came on after only 4 months with the vehicle. The vehicle also abruptly slammed on the automatic brakes when backing into a parking spot with no obstacle present prior to the service lights indicating any issues. The vehicle was diagnosed with a failed brake master cylinder nearly two weeks ago, but the part is still on national backorder and will be stuck at the dealership for an undetermined amount of time with no loaners available. There are plenty other accounts of this same issue happening to other newly-bought '25 Traverses, and the N242482170 bulletin related to the '24 model hints at this being a recurring issue. This safety issue on a brand new vehicle without recognition/resolve is unacceptable.
On September 30 I was on my way to work as I was merging to join a busy highway my breaks failed to work. I had to press them really hard but it took for ever to yield. I made hand signals to the cars I was about to strike and they were able to break before I hit them as I was merging. When this happened 3 service lights appeared. Service ESC system, Break assist failure. Press hard to break.Speed limited. Key missing, check for key. i had an appointment for a cracked windshield on Friday the 3rd and Richland Chevrolet in Roswell. I took my traverse in on Wednesday afternoon and never heard back from them. on Monday October 6 I called and they advised me that my car needed a master cylinder and it was on back order. They said they could not give me an ETA because they have no idea when it will be available. They do not have a loaner because I did not purchase the vehicle their so I called the dealership where I bought it and they cant help me either.
Warning light ‘Service Electronic Stability Control’ appeared 2 days ago. Vehicle feels unbalanced, steering wheel has excessive play (like driving a boat), and control is compromised. Mileage over 10,000. Safety concern due to difficulty handling.”
My chevy has 3000 miles on it and the service the brake Assist and service the ESC Information flashes on the screen and the Brake and ABS lights are lit up.
Was traveling down the road at about 45 mph and the dash started to show a brake assist failure error and alarm. The brakes would not work and nearly went through the intersection during a red light.
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.
my wife was driving and she got warning lights for "brake assist failure" "speed limited" and "Service ESC". Brake pedal went all the way to floor and she came to a rolling stop. She couldve been in a accident if there were vehicles in front of her and it was also near a school bus stop. We recieved the vehicle from the shop a week ago today for other issues. (onstar). Was also in shop at dealership prior to that for coolant leak, a/c failure and a loud humming noise. Also door latch to rear hatch.
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.
- Brake assist system failure -Electronic stability control alert - Brake pedal goes to the floor and car doesn't stop -Potential master cylinder malfunction due to faulty part. (See photo below). Safety of self and others put at risk as car became uncontrollable due to complete loss of braking power while driving. Dealership has not notified yet due to long waiting of other vehicles undergoing maintenance (in my case 2 days at time of this report) Part hasn’t been inspected yet. Issue seems in line with similar incident referring to other 2025 and 2024 Traverse molels. Warning signs and alerts appeared only at time of incident (See photo below)
Dashboard started showing brake assist and esc needed service. Four lights lit up: brake, abs, traction, and collision
the whole dashboard lit up with break and park indicator lit up in red on dashboard. warning flashed about automatic break system failure and ESC warning
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.
Several alerts came on, including ABS light, SERVICE ESC, SERVICE BRAKE ASSIST, ADAPTIVE CRUISE CONTROL UNAVAILABLE. Blind spot alert stopped working. Dealership reset everything but the issue came back within a few hours. They said it may have something to do with the brake system
The ABS break service warning appeared in the info screen. I have less than 3000 miles on it. The dealer said the car should not be driven. They had to order the parts, Master Cylinder, reservoir kit, etc. They also said there was a GM Bulletin on this issue.
