Service Brakes Problems of Chevrolet Traverse - part 1

The contact owns a 2024 Chevrolet Traverse. The contact stated that while driving out of the dealer's parking lot at 4-5 mph and depressing the accelerator pedal, the messages "service esc system" and "brake system failure - press hard to brake - do not drive" were displayed, and the check engine warning light illuminated. The contact stated that the vehicle failed to respond while depressing the brake pedal, and the vehicle rolled to a stop. The vehicle was taken back to the dealer, where the failure was associated with the braking system. The dealer disconnected and reconnected the battery, and the dealer cleared the codes. The dealer informed the contact that the vehicle was repaired and returned the vehicle to the contact; however, the contact stated that the dealer had failed to determine the cause of the failure and to perform an adequate repair of the vehicle. Additionally, the contact stated that the brakes had been making an abnormal squeaking sound while the brake pedal was depressed. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, and a case was filed; however, the contact had not yet been contacted. The failure mileage was 16,876.

While driving on the interstate, the anti-collision system activated when a car swerved in front of the vehicle. The vehicle stopped and resulted in a brake failure after that. All brake warning lights came on the dash, message stating brake failure and drive with caution and limited speed was displayed. Brakes were no longer working properly.

The contact's wife owns a 2024 Chevrolet Traverse. The contact stated that while his wife was driving 60 mph, the brake pedal was depressed and went to the floorboard, and the vehicle failed to respond. The driver engaged the parking brake; however, the vehicle failed to respond. The driver swerved to avoid the vehicle in front, drove over an incline, jerked the steering wheel, and the vehicle eventually stopped. The message "braking module system failure" was displayed. The contact stated that the incident was frightening for his wife and his two children, who were also inside the vehicle. The vehicle was towed to the dealer, where it was acknowledged that the braking system module and the parking brake had failed; however, no official diagnostic information was provided. The vehicle was repaired under warranty, and the contact was advised that the vehicle was drivable; however, the contact advised the dealer that there were safety concerns because the cause of the failure was not yet determined, and there was no guarantee that the failure would not recur. The vehicle was driven back to the residence, although the contact remained concerned. The manufacturer was notified of the failure, and a case was filed, but no further assistance was provided. The failure mileage was approximately 28,000.

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.

Driving home coming up to a traffic light - I turned left onto rd - after turning lost the brakes. Saw message on dashboard along with many others indicators as well. Saw the same message as the previous time ““brake assist failure. Press hard to brake. Speed limited”.

Burning oil. There is something wrong. I took it to the dealership I still have warranty I really think this needs to be looked into.

The contact owns a 2025 Chevrolet Traverse. The contact stated while driving approximately 70 mph, the vehicle shifted into limp mode, causing the vehicle to decelerate unintendedly. During the failure the headlights and the interior lights flashed and flickered, and the abs, traction control, and several unknown messages were displayed. While depressing the brake pedal, the brake pedal extended to the floor and the vehicle failed to immediately stop. The vehicle was later towed to the local dealer who recharged the battery and performed a software update to the crucial control module. The contact stated that three weeks later the same failure had reoccurred. The local dealer and manufacturer were notified of the failure. The failure mileage was 9,995.

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.

Driving home - what looked like warning indicators on the dashboard, came on. Lost the ability to brake. Had to push the pedal all the way to the floor to get some braking to happen. A message came on the dashboard “brake assist failure. Press hard to brake. Speed limited”. Once we were able to stop. We turned the car off. Then turned it back on. We saw a message on the dashboard to “open the drivers door” and then “roll down the drivers window”. We did that and the car seemed to be normal again.

I got my 2024 Traverse little over a year ago. So far I had bring it in 3 times now first I got oil change and they told me something leaking from back so I went chevy and the transmission was leaken bolts wasn't put in all the way. Also my breaks said they was due I bring back to them they said its a sensor probelm they just turned it off. Now im back again horse is crack and they said I could come get the car and drive it that it would be fine just to keep checking collent. I got 38,000 miles.

Vehicle experienced uncommanded automatic emergency braking with no warnings or obstacles present. Sudden hard braking caused fear of collision. Children were in vehicle as well as two adults. Vehicle has prior collision repairs. Owner fears highway driving due to risk of recurrence.

The contact owns a 2025 Chevrolet Traverse. The contact stated that while her husband was driving at 30 mph on an expressway, occupied with his wife in the vehicle, seated on the front passenger side, attempting to depress the brake pedal, the vehicle failed to respond as intended, causing the front end of the vehicle to crash with the rear end of the vehicle in front. The contact mentioned that the brake pedal felt abnormally hard and excessive force was applied; however failed to bring the vehicle to a stop, causing the crash. The air bags did deploy. The vehicle was towed to a tow yard, the vehicle was then towed to the insurance company. The contact stated she and her husband did not sustain any injuries. No medical attention was required. A police report was filed. The manufacturer was not notified of the failure. The approximate failure mileage was 2,000.

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.

Vehicle currently at dealership for esc, brake system and abs warning lights coming on. Unable to use cruise control once these lights came on.

I started the vehicle to move it to a different place in my driveway and after putting it in reverse, it notified me that the abs was not working. I could not stop the vehicle without pressing the brakes very hard and even then it was still rolling backward slowly. I quickly put the vehicle in park before the car rolled into my house.

2025 Traverse abs brake system failed, and master cylinder broke at 12k. All of the safety features, lane departure, forward crash detection, blind spot, automatic braking system all stop working with no signs that it was failing! extremely unsafe! Traverse are meant to be family vehicles, well with major functions failures this kind of problem is going be recipe for disaster if not recalled ASAP.

On Monday, December 15, 2025, I was "creeping" into my garage when the brakes failed and I ran into my garage wall damaging my wall and the front of the vehicle. On Tuesday, December 16 ,2025, while slowly pulling into a parking spot at sam's club in okc, the brakes again failed, and the forward crash system prevented running into another vehicle. On that same date while stuck in bumper-to-bumper traffic, the brakes again failed, and I was able to pull into the median rather than hitting the car in front of me. That same evening, while backing out of a parking spot at a restaurant, the brakes failed in reverse and again the vehicle reverse crash avoidance system stopped without hitting another vehicle. Later, as I was leaving the parking lot, the brakes failed at the stop sign, and I was able to turn right in the merge lane avoiding hitting another oncoming car. At the very next stop sign, the brakes failed again, and I was able to get the car into park avoiding another head on collision. All these brake failures happened at speeds under 5 mph or barely "creeping" forward or reverse. I drove the car to cummins chevy dealership in weatherford, ok, the next day and related the issues to them. They gave me a "loaner" for use until they fixed my car. The service manager did ask me if I had "tagged" my car yet and I said I had. So far, gm and cummins have been very helpful and understanding. I had no issues "braking" the car at speeds above 5 mph. I have only had this vehicle for 3 weeks when the issues started. I love the vehicle and hope this is only a minor glitch or some bad part that can be replaced. I file this complaint proactively in case it is a bigger problem with this line of vehicles. Thank you.

Brakes have squeaked since the day we bought our brand new vehicle. I have contacted the dealers and called corporate. The answer I have received from both is”it is the material they are making the brake pads out of. ” we paid over $50,000. 00 for our vehicle and do not want to deal with squeaky brakes all the time. They will not do anything about it.

Brake assistance failure. Brakes failed! esc service I was able to set it up for inspection could of caused a accident hurting other people or hurting my family, I use this vehicle to transport my 2 babies vehicle would not brake properly could have cause serious injuries for my vehicle not yet has not been inspected it was towed, from what I have heard from current Traverse owners they have experienced this same issue with even lower milage no warning lights no indications of failure just happend instant twice.

Engine light came on . Warning low coolant turn car off engine over heating. Fan still running after turning off. Happen several times. Serveral days. Took in in to dealership because still under warranty. No longer car available despite under warranty. Also breaks alerted low break pad life in around July 2025 and took it in the dealer and said it was a update not completed.

My brakes, abs, front collision, esc light are on and dealership continue to try to fix and no luck. I have take 3 times in the last week with no luck. I need this fixed because I bought for safety features and now I have no vehicle to drive to work.

Engine overheating light comes on, car leaking fluid. Possible radiator or radiator hose. Unsafe to drive breaks are squeaky and bad.

Completely disgusted with chevy Traverse. Upper radiator hose busted and radiator leaks at seem, squeaky brakes since day one purchased then sensor on brakes went bad causing it to say brakes are less than they actually are says 18% and it’s actually 88% caused the engine light to come on ppl can’t afford a payment and be at the dealer all the time and without transportation. It’s my only vehicle and I need it fixed but everyone says part is back ordered or something this is a shitty vehicle chevy needs to pay to replace brakes sensor hoses and radiators even if it’s past factory warranty these vehicles cost to much not to last past 36,000. Ridiculous there needs to be a recall this is becoming a very well known problem chevy should have to cover to fix it and make it right and provide a vehicle while it’s in the shop. Very upset with chevy and it’s quality and this needs to be recalled ASAP.

Squeaky breaks coolant leak engine heating warning check enginelight comes on after each gas visit car sounded super load when engine is running due to constant coolant leaks car doesn’t feel safe to drive with 4 young kids!.

What component or system failed or malfunctioned, and is it available for inspection upon request? defective brake causing sudden brake loss how was your safety or the safety of others put at risk? yes has the problem been reproduced or confirmed by a dealer or independent service center? not yet has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? not yet were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? after the incident a message appear on the dashboard.

Bought vehicle on 11/28/25. By 11/30/25, brakes squealing and large puddle of coolant in driveway. Took back to dealer on 12/1/25, told special radiator hose that is on backorder all over country. Unknown eta.

Break pads wear unevenly after only 20 thousand miles and need to be replaced.

This vehicle is unsafe for two reasons. First, it slams you on brakes and puts you in park at random times. Middle of road, parking lots, etc. This puts you at higher risk of someone hitting you. The second thing is when pressing the gas when taking off after a stop, the rpm’s jump up and the engine revs up, but the car is barely going. Not safe when crossing intersections along with many other times. Both of these puts mine and my families safety at risk along with others on the road. No warning signs, lights, etc. Car is in shop for second time. First time on November 28, second time on December the 11. Still no answer on a fix. Just that they think they may know the cause. The dealer has gotten the car to reproduce these issues.

The contact owns a 2026 Chevrolet Traverse. The contact stated that while driving at 35 mph, the check engine warning light illuminated. The vehicle was taken to the residence. The contact stated that while making a right turn into the dealer to have the vehicle diagnosed, the brake warning light illuminated. The vehicle was diagnosed, and determined that the brake master cylinder needed to be replaced. The vehicle was not repaired because parts were on back order. The manufacturer was notified of the failure. The failure mileage was 500.

We drove the car to the store and everything was fine we went in to shop. We came back out and I turned the car on and my dash board had lights on. My brake light will not turn off . My abs light is on. My forward collision light is on . . I am getting a notice to service esc, and a separate one saying service brake assist . I ran a onstar diagnostic and it came back everything is good. I have not brought it into the dealership yet for them to look at it I will be calling . I have multiple children and I was so scared my brakes were fulling going to give out on my 20 min drive home. I couldn’t imagine what would have happened we could have hurt someone else on the road and ourselves.

Brake booster failure, master brake cylinder failure.

I was driving down the road with my 4 year old son in the back and I went to stop at a stop sign and my car immediately lost brakes, the brakes went down to the floorboard with almost little to no stopping of my car. Then I had 3 warnings on my dashboard I can send pictures of them, my check engine light came on, my abs light came on and my traction control light came on. Very scary and something needs to be done about this.

Upper radiator hose leak with 20k miles. Coolant reservoir was completely emptied. Hose needed to be replaced on top of a parts not in stock. No warnings to overheating or coolant leak. Also brakes squeal since day of purchase.

The 2025 chevy Traverse was purchased on 10/27/25 - new. On the morning of 10/31/25, several lights came on for service such as the brake, abs, traction control and forward collison. Through a quick google search, saw there are many issues with the master cylinder leading to brake issues. At this time, the car only has 535 miles. Prior to this incident, the car had no evident issues. I contacted my local dealership to set up an appointment to have the issue assessed and fixed. The appointment is scheduled for 11/5/25. I will not be able to drive the car in the mean time, as it poses a safety concern (brake failure) to my family and myself.

My 2024 Traverse was delivered with defective third-row seat headrests that do not return to their normal upright position after being folded, compromising passenger head and neck protection in a collision. On October 28, 2025, the vehicle developed a coolant leak confirmed by the dealer, but repairs have been delayed due to a national parts backorder, creating a risk of engine overheating or sudden breakdown while driving. Additionally, the front brakes began squeaking excessively about one year into my ownership, and the brake pad wear sensor shows only 18% life remaining at 18,454 miles, which raises concerns about reduced braking efficiency and increased stopping distance. All issues have been reported to an authorized dealer and remain unresolved except for the third-row headrests. These conditions pose significant safety risks to occupants and other road users.
