2025 Chevrolet Traverse: ABS light or ABS activating

Filed Oct 11, 2026 · Brakes, Electrical · FL

Vehicle: 2025 Chevrolet Traverse LT FWD VIN: [XXX] Purchase Date: XXX Incident Date: XXX Mileage: 35,975 INCIDENT DESCRIPTION: On Fr XXX, just seven days after purchasing this vehicle from Enterprise Car Sales, I started my 2025 Chevrolet Traverse and was immediately presented with multiple serious braking and vehicle safety-system warnings. The primary warning stated: "BRAKE ASSIST FAILURE. PRESS HARD TO BRAKE. SPEED LIMITED." Additional warnings included: - Service ESC (Electronic Stability Control) - ABS warning light illuminated - Traction/stability control warning - Forward Collision System Unavailable - Red BRAKE warning illuminated - Check Engine light illuminated These warnings appeared during the same startup event while the vehicle was stationary. SAFETY CONCERNS: I am extremely concerned that a vehicle with fewer than 36,000 miles is reporting a potential failure of its power-assisted braking system, along with simultaneous malfunctions involving ABS, stability control, and forward collision protection. The dashboard specifically instructed me to press harder to brake and indicated that vehicle speed was limited. This raises serious concerns about braking performance and the ability to safely stop the vehicle, particularly during an emergency. I am aware of the federal safety agency investigation EA26006 concerning potential electronic braking-system failures in certain General Motors vehicles, including the Chevrolet Traverse. The symptoms reported in that investigation appear similar to the warnings displayed by my vehicle. The underlying cause has not yet been confirmed. MANUFACTURER NOTIFICATION: I formally reported this incident to Chevrolet/General Motors. GM Case Number: XXX Photographs documenting the warnings and mileage are available. REQUEST: I request that the federal safety agency document this incident as a potential vehicle safety defect and evaluate whether it relates to existing complaints or investigations INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The first component to fail was the brake booster module which controls the ABS, forward collision, adaptive braking, adaptive cruise, traction control system, etc. The malfunction started when the forward collision assist activated to prevent me from hitting a deer in the road. We avoided hitting the deer but all of those lights came on immediately. We contact Friendship Chevrolet the dealer we bought the car from had us bring it in to be checked. They confirmed the defective Module and said that it was a reported issue that GM had it's engineers looking at. They said they would have to wait for the part to arrive, advised that we could continue to drive the car even though there was a major malfunction with the critical braking systems. did not offer any type of loaner to ensure my family's safety. We had to wait for more than 30 days for them to receive the part and complete the repair still driving this unsafe vehicle because we had no other choice considering how high the MSRP & payment is on the vehicle. Once the repair was finally completed we immediately began to notice that the brakes were consistently screeching when in slow moving traffic like car rider pick up line. I reported the issue to the dealership and they gave me the answer that it was due to a more abrasive brake pad being used due to it being a passenger vehicle and it's weight. We continued to deal with the squeaking for months then we noticed a coolant leak. Dealership again said had to wait for part. After they did not contact me back I contacted GM and opened a case. When they got it in I also had them change the brakes out of my own pocket. Now the brakes squeak anytime pressure is applied and when coming to a complete stop they grind so loud you can hear and feel them digging in. GM still says nothing is wrong and brakes are a maintenance charge and are not covered for any reason. I feel the vehicle is still extremely unsafe and my family is at risk of possible crash.

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.
