2025 Chevrolet Traverse

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.

Name: [XXX] •Address: [XXX] •Phone: [XXX] •Email: [XXX] Date of Incident: October 7, 2025 Description of Problem: While driving our 2025 Chevrolet Traverse on October 7, 2025, our son was sitting in the third-row seat and somehow managed to buckle two seatbelts at once—one from the right side and one from the left—crossing them over his chest and neck. Once both belts were latched, they locked in place. When we tried to loosen one side, the opposite side only tightened further, causing him to be choked. We tried multiple ways to release the seatbelts, but the locking mechanism prevented any movement. Several adults tried to help, but no one could free him. We ultimately had to cut one of the seatbelts to safely release him. He was left with visible red marks on his neck, and the incident caused significant fear and distress. The seatbelts were crisscrossed, which explains why attempting to loosen one side made the other side tighten. This appears to be a dangerous design issue, as there was no safe or quick way to release the belts in this situation. We are deeply concerned that this design could pose a serious strangulation hazard to children or other passengers in the future. Attachments: •Photos showing the crisscrossed seatbelts •Photos showing the red marks on the neck after the incident We request that NHTSA review this complaint to determine if this is a vehicle safety defect and take any appropriate action to prevent similar incidents from occurring.

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.

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.

One day My husband went to work and the antenna fin was attached, he came back home and it was no longer there . We do not car wash my car since its brand new. We hand wash it our selves there should be zero reason for that to come off. Apparently is a very common problem in the 2025 traverse. I joined a Facebook group and over 40 people had the same issue.

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.

I star failed and I could not use any of my lane assist. All features quit working that were to help me with other cars approaching failed. Radio quit work it working. Battery in car needed to be replaced and car needed to be jumped started. Curse control did not work. Had less than 2000 miles on car. Safety features in car quit working.
