2025 Chevrolet Traverse

This started happening about two weeks ago. My check engine light came on and my OBD scanner said a NOX sensor code showed. I told the dealership and I guess they cleared the code and it hasn’t reappeared but the reduced acceleration has maintained. It was [XXX] I had just go of work and needed gas. While traveling to the gas station I got notification that my acceleration was being reduced and it was very noticeable. After arriving and pumping gas, I started the car and got 3 additional messages. The car aside my brake assist and ESC needed service, my ABS system was off, and my forward collision system was off. While driving, I noticed that the brakes were still working but acceleration was still being reduced. This is an everyday use car and I have a 6 children who I don’t feel are safe anymore in the car. Not being able to utilize the brakes and the reduced acceleration is very concerning especially when in traffic. I have a little over 27500 miles on the car. It just came from the dealership to get the telematics module replaced last week because it went out about a month ago. I’ve only had this car a year and it seems like the issues are becoming more common everyday. I will be taking care back to dealership tomorrow.

Our car one day showed several illuminated dash lights regarding brake system, along with several pop up warnings. We took it to a Chevrolet dealer for service. They’ve had it for 54 days. They’ve confirmed widespread brake system and electrical system failure, but even after escalating to corporate tech assistance, there is no progress nor resolution available. We were told they have at least a dozen others with this same issue. It is wildly inappropriate that there has not been a recall issued as this is a serious safety defect. We demand a buyback from GM for putting this death trap on the market knowing they had these issues with 2024 models but continuing to roll 2025 and 2026 models with the same issues.

I purchased a brand-new 2025 Chevrolet Traverse and have been dealing with a loud brake squeal that makes the vehicle sound like it has worn-out brakes. I’ve taken it to two different Chevrolet dealerships, and instead of fixing the issue, I’ve repeatedly been told that this is a common problem with the 2025 Traverse and that many owners are experiencing the same thing. I’ve been given multiple explanations, including weather conditions and the vehicle needing to warm up, but no actual solution. I was even told there is currently no fix available through GM and that replacing the brake pads will not resolve the problem. What is most frustrating is that everyone seems to acknowledge the issue while also telling customers to simply live with it. This is a brand-new vehicle, and customers should not be expected to accept a known brake defect as normal. Very disappointed with both the dealership experience and GM’s response to what appears to be a widespread issue.

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.

We drove the Traverse 55 miles to a baseball game. When we got in the car to return home several warning lights appeared on the instrument display and there was an audible warning sound. The message “Service ESC” and “Brake assist failure” appeared on the instrument display panel. We couldn’t find a dealership that was open on Saturday so we cautiously drove 55 miles home. The brake pedal was hard to push and had to be pushed all the way to the floor to stop the vehicle. We could not drive faster than 62 MPH on the way home and I had to start braking early in order to be able to come to a complete stop at stop lights. Cruise control isn’t working either and the audible alarm sounds off every couple of minutes. We took the car to our local dealership this morning.

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!!!!!
