When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2026 Chevrolet Traverse

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

1 investigation is still open.

Electronic Brake Module Component Failure

On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until th...

Recalls on the 2026 Chevrolet Traverse

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, “Occupant Protection.”

Risk: Without an owner's manual to consult, owners may not know how to safely use and operate the vehicle, increasing the risk of injury in a crash.

Issue: On certain vehicles, the owner's manual may be missing. As a result, the vehicles may not meet certain requirements of Canadian regulations. Note: For the Escalade model, the recall also affects certain 2026 model year Escalade IQ and Escalade IQL models. Safety Risk: A missing owner's manual could cause confusion on how to safely operate the vehicle and increase the risk of injury or a crash.

SERVICE BRAKES

On August 25, 2026, my 2026 Chevrolet Traverse experienced a severe safety failure involving the Automatic Emergency Braking (AEB) system. While moving slowly forward in a drive-thru lane with no obstacles in front of the vehicle, the car's automated systems unexpectedly and violently slammed on the brakes.The vehicle brought itself to an immediate, harsh stop without any actual hazard present. The sudden, uncommanded application of maximum braking force caused severe physical jolting, resulting in a whiplash injury to my neck.This unexpected braking event creates an immediate crash hazard for vehicles behind me and poses a severe risk of physical injury due to violent, unprompted stops. This incident appears directly related to ongoing electronic brake module and automatic braking system malfunctions under active federal investigation. I request a thorough safety investigation and a formal recall to address this dangerous defect.

Watonga, OK Crash

SERVICE BRAKES

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.

ELECTRICAL SYSTEM

The blind spot warning sensor goes off at random. Making the driver not know if an object is close to the vehicle. This is very dangerous as a driver because you can get used to it going off and getting comfortable with nothing being in your blindspot, even with the warning light on. What happens when there actually is something in your blindspot? As you can see in the picture below, there is nothing in the mirror and the blindspot warning light is on. It has been this was since it came off the lot at the dealership. We have been told there is no fix for it. We would like to see a recall for this particular sensor before it becomes a problem.

On start-up, intermittently the center display freezes, the HVAC system defaults to 76 degrees with the a/c and defrost stuck on with the blower on high. No driver input possible through the center display. Condition may clear by itself or not even through several shut downs. Numerous DTC's set. Always a CEL. For me, 2x dealer (repairs). They reprogram controllers. Condition not corrected. Possible HMI and/or HVAC controller hardware problem. Dealer doesn't know how to fix. Casual internet search indicates many identical complaints. Concern is, HVAC control is a basic function that should function correctly. Driving in the winter with no heat and a fogged windshield is a safety issue. GM is aware of the problem and has no fix.

When shifting into drive from start, the shifter does not shift. I have my foot on the brake at the same time also. This has happened at least 8 eight times sense the SUV went over 3500 miles on the odometer. I have to wait about 5 seconds before trying it again. This is a safety item that needs immediate attention by Chevrolet and GM, If I needed to evacuate an area, or my garage in the event of a fire and the shifter fails!!!?? should I take it back to the dealer and ask for a refund?? O give them a chance to fix it?

While driving on the freeway, the vehicle’s battery shut down.

To recharge, try and start in a well-ventilated area. If it won't turn on, try to jump start or call 1-888-4-ONSTAR. Text STOP to cancel.” This situation was life-threatening and scary.

VEHICLE SPEED CONTROL

I am reporting a serious safety concern involving my 2026 Chevy Traverse that occurred on May 9, 2026 at 6:46pm. While driving at freeway speed in the carpool lane with adaptive cruise control and gap assist engaged, my vehicle suddenly applied the brakes unexpectedly even though there were no vehicles directly in front of me. The nearest visible vehicle was a significant distance ahead, and there was no apparent reason for the braking event. This was not a gradual deceleration. The vehicle actively braked. I was passing under or near an overpass at the time, which makes me wonder whether the sensors misread something. Regardless, the sudden braking created a dangerous situation because vehicles were behind me, and the driver behind appeared to think I was brake checking them. This could have easily caused a rear end collision. As a result of this incident, I no longer feel I can trust these safety/driver assistance systems and have since disabled those features because I do not feel safe relying on them until this issue is properly investigated and addressed. I am requesting that this issue be formally documented, that the vehicle be inspected for any malfunction related to adaptive cruise control, automatic emergency braking, forward collision warning, or related sensor systems, and that I be advised whether this is a known issue with the 2026 Traverse. If there are any software updates, technical service bulletins, recalls, or corrective actions available, please let me know. This is a serious safety concern, and I would appreciate guidance on the next steps.
