Filed Oct 19, 2026 · Brakes, Driver assistance · 19,357 miles · NC · 2 injuries

The contact owns a 2025 Chevrolet Traverse. The contact stated that while driving, approaching a traffic light, the Electronic Stability Control (ESC), rear collision warning, service assist, front collision warning, check engine light, and multiple brake warning lights illuminated. The emergency brake failed to function. The vehicle was towed to a local dealer, where the master cylinder failure was diagnosed, and the part was replaced. However, while driving after the repair, a complete brake failure occurred alongside the same warning lights. The contact lost control of the vehicle and traversed two intersections. The contact attempted multiple times to stop the vehicle, and the contact's daughter exited the moving vehicle before the contact stopped the engine by depressing the ignition button. The police were contacted, and a CAD report was generated. The vehicle was towed back to the dealer, where a second master cylinder failure was diagnosed and repaired under warranty. The failure mileage was approximately 19,357.

The contact owns a 2025 Chevrolet Traverse. The contact stated that while driving 40 MPH, the semi-truck in front of the vehicle started slowing down and the contact depressed the brake pedal and the brakes failed. When the brake pedal was first depressed the brake pedal was extremely firm. While forcefully depressing the brake pedal the brake pedal went to the floorboard and the braking distance became extended. The Brake Assist Failure, Warning Brake, Park, ABS, Starter Control, Crash, and ESC warning lights were illuminated. Additionally, the parking brake was inoperable, and the vehicle was coasted to a stop. The contact became aware that there was fluid leaking underneath the vehicle. A Police report was filed. The vehicle was towed to the dealer. The manufacturer was contacted by phone and made aware of the failure. The failure mileage was approximately 21,589.

At approximately 30,000 miles, upon starting my 2025 Chevrolet Traverse LT, the brake pedal traveled completely to the floorboards with zero resistance. Simultaneously, the 'Service Brake Assist' warning message appeared. This loss of hydraulic pressure occurred while stationary. This follows a dealership visit one week prior for a 'glitchy' check engine light that was dismissed by service staff.The vehicle is being towed via flatbed to the dealership as it is unsafe to operate. Additionally, the vehicle has exhibited abnormally 'touchy' brake response and a persistent high-pitched squeal from the front assembly since purchase. These symptoms suggest a failure of the e-Boost braking system and/or internal master cylinder seals, consistent with Service Update N242482170. This defect poses an immediate risk of total brake failure during operation.

I was driving through the tollbooth on the bayway in [XXX] , I stepped on the brake to slow down and all kinds of warning lights lit up in the car showing the brakes were not working. Anything automatic with the brakes failed. I had to stand on the brakes to get the Traverse to stop. The issue was confrmed to be the master brake cylinder I was lucky they had it in stock at Maher Chevrolet in St Petersburg. My grandson was supposed to be in this car the next day driving over the skyway bridge. The safety of children is being compromised. Please issue a recall!!!!!

Turned on vehicle on 3/2/2026 and received a message stating "Anti-lock break system failure. Drive slow and stop cautiously." I test drove my vehicle in my local neighborhood and discovered that my brakes were only functioning at about 20% and would only respond if the brake petal was pressed all the way down. My car was towed to the local dealership to be assessed and was determined to need Reservoir 4.651, Cylinder 4.650, and Fluid 8.800 when it was picked up on 3/6/2026. Under further review of this report I came to discover a class action lawsuit for this vehicle make and model relating to cylinder part #85762161. I am unsure if my original part was that part number, but my experience closely mirrors other's that have been reported for the same issue and part repair. The part that was also replaced in my vehicle after the repair was part #85762161. Some individuals in this lawsuit have reported 100% brake failure. I am fearful to continue driving the vehicle knowing that there could still be ongoing issues with the part that directly relates to the brakes.

Initially, the engine would intermittently fail to start and at times would not start at all. I took the vehicle to a certified Chevrolet service center, where the battery was tested and found to be functioning properly. They later concluded that a faulty front-view camera was disrupting the electrical system and ordered a replacement (my first visit was Friday, 9/26/25). I took the car home for the weekend due to family obligations. On Monday, 9/29, while driving back to the service center, the engine suddenly shut off on a local road. The brakes went completely to the floor for 3–5 seconds before the engine restarted—just before I nearly collided with another vehicle at a red light. I reported this immediately, and the dealership kept the car for further testing. On Thursday, 10/2, they informed me they found no additional issues and believed the camera was the root cause. However, the problem persisted. On Sunday, 10/5, while stopped at a red light at Hawthorn St. and Memorial Dr., the engine shut off again as I began to accelerate. The brakes sank to the floor, and I had no steering control for approximately 5–7 seconds before the vehicle restarted. My wife and I were extremely shaken, especially with our children in the car. On Monday, 10/6, we contacted roadside assistance to tow the vehicle back to the service center. After additional testing, we were informed that the battery had failed this time and was replaced. However, replacing the battery does not reassure us that the engine and braking system will not fail again while driving, or the brake failure would happen again when the battery is low - which poses a serious safety risk to our family. When my wife called GM to report this issue, all they offered was 200 points worth of rewards....We originally bought this car for safety, but not this has been compromised and we no longer feel safe. Thank you for your attention to this matter. I am happy to provide any additional information if needed.

While driving, ABS, traction control, ESC, forward collision, and AWD alerts were indicated by the car. At the time it had 10 months in service and approximately 12,800 miles accumulated. After 17 days at the dealers service department and a direct call to GM the brake master cylinder and associated components were replaced. I've seen several reports of this generation of Traverse having this same issue for other owners at low mileage. I want to file this report to ensure that NHSTA is aware of this serious safety concern that could result in loss of braking power. It appears to be widespread and not addressed by any recall and dating back to the 2024 model year change to the most recent generation.

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.

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.

- 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)
