I experienced complete brake failure while coming up to an intersection during rush hour. To avoid crashing into the vehicles in front of me I went off the road onto the shoulder and coasted until I stopped. During this “brake failure” popped up on my dash. (I have a picture) I ended up turning the car off and then starting it back up. Everything appeared to be fine, however I was not fine. I called the dealership right away and brought in. They diagnosed it as needing brake master cylinder and it took about 30 days for the vehicle to get fixed. Now I’m experiencing transmission fluid leaking. The vehicle shudders when accelerating.

My vehicle began to really wobble and shake so I brought the vehicle to the closest tire shop. They told me right away that the belt broke on one of my tires, the tire was bulging, and the tire was beginning to split apart. Then he showed me how the other front tire was beginning to do the same. He said had I not taken it there,…

My vehicle began to really wobble and shake so I brought the vehicle to the closest tire shop. They told me right away that the belt broke on one of my tires, the tire was bulging, and the tire was beginning to split apart. Then he showed me how the other front tire was beginning to do the same. He said had I not taken it there, it would have soon blown out. This is a serious safety concern. My vehicle is less than 2 years old and has 28,000 miles on it. Bridgestone tires should last at least between 50-60,000 miles. Tire: 255/65R18 111T M&S.

This has happened two times. Driving down the road between 35-55mph. "Speed limited drive with care" no CEL. Took to dealer, advised with a CEL or no codes nothing they could do for it. Multiple nights I get home and the fan stays running after engine shutdown. Engine overheat within 10 min of drive time. OIL SMELLS LIKE FUEL. This time engine throttles back and nearly caused accident with not being able to merge.

I am filing this complaint regarding a persistent and unresolved defect with my 2024 Chevrolet Traverse, VIN: [XXX] . The first occurrence of this issue was in June 2025. Since then, the vehicle has repeatedly experienced a “Check Engine” warning, engine misfires (cylinder misfire), loss of power while driving, and severe engine shaking. These symptoms make the vehicle unsafe to operate. The vehicle has been taken to an authorized Chevrolet dealership approximately 20 times for the same ongoing issue. Despite multiple repair attempts, the problem has never been permanently resolved. In total, the vehicle has spent about three months out of service at the dealership. As of January 14, 2026, after the vehicle has been at the dealership for over two weeks, I was informed that the dealer is unable to repair the vehicle. They have escalated the case to the manufacturer, General Motors, because they cannot identify a permanent solution. The current mileage of the vehicle is approximately 41,700 miles. This ongoing defect makes the vehicle unreliable and unsafe for normal use. The repeated failures to repair suggest a potential manufacturing or design defect rather than an isolated incident. I respectfully request that the National Highway Traffic Safety Administration review this matter and determine whether an investigation or further action is warranted.

I am experiencing a recurring battery/charging system detection warning with my vehicle that has not been resolved despite multiple service visits. The warning continues to reappear after the vehicle is returned to me, indicating the issue has not been properly diagnosed or repaired. My vehicle has been in the shop approximately 5 times for this same issue. Each time, I am told the problem is resolved or that they cannot replicate the issue, yet the warning returns shortly afterward. To date, no permanent fix has been provided, and the underlying problem has not been remedied. I have made repeated attempts to work with GM and the dealership, but meaningful assistance or escalation has not occurred. This ongoing electrical issue raises concerns about the reliability and safety of the vehicle, as well as GM’s failure to correct a known, documented problem. I am requesting appropriate escalation and resolution, including further diagnostic intervention by a regional service manager or field engineer, or consideration of alternative remedies if the issue cannot be permanently repaired.

Recurring failures related to brake system. When reversing, the rear brake assist system slams on the brakes for no reason even though no obstacles are present. This startles everyone in the vehicle and nearby traffic. On other occasions, the vehicle shows an error on the instrument cluster stating "Rear Brake Assist Unavailable". More recently, a persistent error began appearing on the instrument cluster stating "Service Brake Monitor", indicating a failure of the brake pad sensor. On top of all of this, the brakes are noisy and squeaky to the point where it wakes up my neighbors.

Purchased my vehicle brand new in October 2024 and around 3000 miles give or take the front brakes started to squeal. I reported the issue to the dealership on several occasions and was told this is normal due to dust, etc. I have owned 3 brand new vehicles in my lifetime and I have never had this issue with a brand new vehicle with 3000 miles or less on a vehicle; especially a vehicle purchased for almost $60,000. My vehicle currently has 17,000 miles and the squealing continues just as it was at 3,000 miles. My front brakes currently show 18% brake life left on the dash in the vehicle status. This is unheard of for a brand new vehicle to be needing brakes this soon. Which would explain the squealing brakes, they have placed cheap brakes, rotors, etc on this new model. If it weren't for this vehicle status feature showing the life remaining for each component, I could possibly unknowingly experience brake failure and would not have been aware that the brakes were at the end of life so soon; almost less than a year from purchase. This issue needs to be addressed with the manufacturer and looked into before someone driving a brand new vehicle, thinking they still have good brake life ends up killing themselves or someone else due to brake failure.

1EA26006 · Electronic Brake Module Component Failure
Opened Aug 21, 2026 · No close date supplied
Status: open (inferred from source dates) · Service Brakes
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.
