2025 Chevrolet Traverse Complaints

While driving the steering wheel will intermittently lock up or make it where you cannot turn the steering wheel at all. The collision sensors will go off and cause vehicle to lock the brakes up when you’re not even close to anything. Also, random messages will appear in dash as shift to neutral while driving ect. See pictures.

My car randomly started alerting me of “ECS service” & “Brake assist service”. The dealership essentially did nothing even though there is an active recall on the 2024 models.

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.

Onstar Module not working/backorder

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.
