2025 Chevrolet Traverse Driver assistance Problems

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.

Wife had car sitting over night from doing a EMS shift. Went out to car in morning to start to return home and when car started ABS light, ECS light, Brake Light, and Collision light came on. This has resulted in no ABS or safety features. Called dealer and can't look at car for over a month. There was no mention about not driving. If the wife needs ABS or front radar, she will not have it resulting in a more serious accident.

Approx 5/19/26 Forward Collision Detection check light randomly came on when driving home and showed notifications showing "Service ESC" "Service Traction Control" then started showing notifications for the collision sensors unavailable and continuously flickering them across the dash. The Fwd collision symbol would come on and off randomly. Finally was able to take it to the dealership on 6/8/26. Dealership found 6 codes and updated the image processing module. The Fwd Collision symbol is back on and off, notifications are flickering across the dash more frequently and now the check engine light is constantly on as of 6/14/26. Car is currently back at the dealership. Pictures and videos were taken of the issue happening to provide extra proof and given to the techs. These sensors failing at any time could cause the vehicle to randomly brake, not brake, and possibly not register a potential accident and avoid it. This vehicle is our daily driver and is the vehicle my son's car seat is in so it's not just my safety, it's the safety of my wife and baby. It's the safety of anyone else who has this type of vehicle with these issues. Understandably it's always the drivers responsibility to pay attention to the road and surroundings but there's nothing the driver can do if the vehicle randomly shuts off or stops or slams on the brakes or another type of malfunction while out on the road. This vehicle has been in and out of the dealership 5 times now for three different things, every time it's picked up, the problem is still there or comes back within days. It's a pain moving all the baby gear back and forth, on top of the rentals we have been given have been so small, you can't even fit a stroller and groceries per-say in the trunk.

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.

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.

May 8, 2026

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.

Incident

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.

I turned my vehicle on and my brakes, ABS, traction control and anti collision lights all came on. Upon research this is a known problem in 2025 and a recall in 2024. It did in fact end up being the master cylinder and brake system that faulted

Incident

Feb 9, 2026

The vehicle has been brought to an authorized dealership for numerous service visits related to electrical system issues that ultimately affected the braking system. During one service visit, the vehicle was returned to me with multiple active dashboard warning lights illuminated related to the braking system, including Electronic Stability Control and Automatic Emergency Braking. I questioned the presence of these warning at pickup and was advised by the dealer that the vehicle was safe to drive and that the warnings would clear on their own. After driving the vehicle for a short period, I became uncomfortable continuing to operate it with brake-related warning lights still active and returned it to the dealer. Upon further diagnosis by a service technician, it was discovered that the vehicle has significant brake system defects requiring replacement of major components, including the brake control module and master cylinder. During diagnosis, the brakes locked and the parking brake would not disengage, rendering the vehicle undrivable. No collision or injury occurred. However, the vehicle was released to me with active brake system warnings and later found to have serious brake defects. Due to the safety-critical nature of the braking system and the repeated electrical and brake-related service history, I am reporting this for documentation and review.

Incident

Jan 13, 2026

I own a 2025 GMC Traverse purchased in July 2025. The vehicle is experiencing ongoing electrical system issues. The GPS and OnStar systems are inoperative, including vehicle location services. The vehicle cannot connect to OnStar or detect a Wi-Fi connection. In addition, the adaptive cruise control is not functioning properly. These systems have been inoperative for approximately 4 weeks. The vehicle was taken to the dealership and I was informed that parts are required, but no repair timeline has been provided. The loss of GPS, OnStar emergency services, and adaptive cruise control presents a safety concern, as emergency response, vehicle tracking, and driver assistance features are unavailable while driving. The issue remains unresolved.

Incident

Dec 1, 2025

My vehicle experienced a brake system failure that rendered it unsafe to drive and required it to be towed to the dealership. I have been informed by the dealer that the issue involves a failure of the left rear brake caliper. The vehicle is currently out of service at the dealership. Because this issue affects the braking system, it is a significant safety concern.

Incident

Emergency braking occurs at random, even if I'm the only vehicle / object on the roadway. This has been ongoing and has been to the dealership three times. It starts back up each time the vehicle gets an update. Adaptive cruise will brake hard due to false emergency braking, but does not always stop accelerating at the set point (has gone as high as 20 mph over the set point previously and brakes would not respond during). Vehicle was not starting and "press brake to start" warning was showing even though brake pedal was pressed. Brake master cylinder had to be replaced along with brake module. When picking the vehicle up afterward, warning light came while vehicle was warming up "service brake assist" and then shortly after the yellow-circled ABS dashlight came on. Dealership said this was a new problem and separate from the brake master cylinder and brake module.
