2026 Chevrolet Traverse

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 the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual “Service Brake System” message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH). Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM’s description of a spindle failure. These reports allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop. The sudden loss of brake assist during a braking event could result in extended braking distance, which increases the risk of a crash or injury. ODI believes further analysis is necessary to assess the potential for failures in GM’s eBoost system to resulting in safety-related outcomes. At this time, ODI is aware of the following vehicles that are equipped with this eBoost system: 2023-2026 MY Cadillac Lyriq, Chevrolet Colorado, and GMC Canyon; 2024-2026 MY Buick Enclave, Envision; Chevrolet Blazer EV, Equinox EV, Traverse; Cruise Origin; and GMC Acadia; 2025-2026 MY Cadillac Celestiq and Optiq. ODI is also aware of 2024-2026 MY Acura ZDX and 2024-2026 MY Honda Prologue vehicles that were built with this system. The Acura and Honda vehicles were manufactured by GM in a joint venture with Honda, and will be included in the Engineering Analysis as peer vehicles. ODI is opening this Engineering Analysis to further assess the safety-related consequences of a failed eBoost system. In addition, ODI is expanding the scope of the investigation to encompass all GM vehicles that share this eBoost system. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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.

Shark fin antenna is loose and poorly attached, flew off after only having the car a few months. Seems this is a wide spread issue amongst Chevy owners

The contact owns a 2026 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The vehicle jerked and bucked. The contact stated that the safety features were inoperable. No warning lights were illuminated. In addition, the contact stated that the failure had occurred while driving at various speeds. The vehicle was taken to the dealer, but the cause of the failure was not determined. The contact was informed that an unknown sensor had been replaced; however, the failure reoccurred. The vehicle was then inspected by a manufacturer’s engineer. The vehicle was not diagnosed or repaired by an independent mechanic or dealer, and the failure reoccurred. The vehicle was taken back to the dealer; however, the failure was not diagnosed. The vehicle was not repaired. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the vehicle was unsafe to transport the three minor children. The manufacturer was made aware of the failure, and two cases were filed. The contact reported the failure by phone and email. The failure mileage was approximately 3,000.

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.

Vehicle fan blower speed changes by itself. Second issue - at times with Apple Car Play, vehicle will state audio unavailable and steering wheel audio control and GPS notifications will not work. Lastly, issue with not being able to use iphone apps, for example, Safari, when phone is connected to vehicle (this has occured since the most recent update). Other iphone apps will work once phone is disconnected. Vehicle has been taken to dealership but not reproduced. Pictures and videos were provided to dealership.

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.

Instrument cluster/driver display malfunction. Driver display is the only source of spedometer, revs, gear selection, mileage, and gas level. Display began flickering black randomly. Spedometer is not able to be seen. All instruments unable to be seen when flickering/display off. Shortly after flickering, display went completely black. Vehicle currently inoperable due to lack of instrument cluster. Vehicle scheduled for service on Monday morning. No warning lamps or other symptoms prior to issue occuring.

Brand new car just purchased the end of March 2026. Went through car wash multiple times with no issues until one day the shark fin antenna came off and broke the plastic anchors. Now the circuit board is exposed to weather hazards. I read online multiple times this is an ongoing issue with this specific make and model and still GM declines to cover this under warranty.
