Defect investigations
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 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.

What 2025 Chevrolet Blazer EV owners say
Most recent owner complaints, unedited.
I am concerned about a significant safety issue with my 2025 Chevrolet Blazer EV. On at least four separate occasions, the vehicle has unexpectedly applied extremely hard Rear Automatic Braking while I was backing up, despite there being no object, vehicle, person, or obstacle behind the vehicle. The braking is so abrupt and forceful that it feels as though the vehicle has collided with something. Because the driver is typically looking over their shoulder while reversing, the sudden stop causes a violent jolt. This has resulted in neck pain and headaches for me and my son on multiple occasions. One of these incidents also occurred while my son was driving the vehicle. We discussed the event afterward and both experienced the same sudden, aggressive braking with nothing present behind the vehicle. The system appears to be activating falsely. This is a serious safety concern. The unexpected braking could potentially cause injury to the driver or passengers and may also create a hazardous situation if another vehicle is following behind. I am requesting that this issue be investigated and repaired as soon as possible.
While backing into parking at a Humble Cow ice cream place. My 2025 Chevy Blazer EV AWD slammed to a stop. I was going 4 mph my spouses head hit the head rest and caused severe pain and stress. We had to go to the emergency room for treatment. This has happened 6 other times 3 since having the required updates and replacement of modules that took several months to complete. She was given medication and lytocain patches for the trauma of her neck and head. She is now afraid to drive in my vehicle. I looked up the situation and found on Reddit and the internet that this is a known issue with Chevy and several other vehicles relating to their braking and eboost system. One work around is to turn off all of the sensors from the settings menu to include parking. It also said to not use the one pedal driving. This is unattainable for a brand new car that I paid Cash $45-$50,000 for and not to be able to use it as intended. Please look into this. I will be filing another complaint with the dealership on 14 September 2026. Something must be done.
Attempting to merge into another lane today. Collision warning emergency breaking triggered and break checked the vehicle behind me. Almost caused me to be rear ended by the vehicle behind me.
I was driving down a road. Vehicle slammed on the brakes and then accelerated in it own causing me to hit a guardrail.
See attached document for complaint.

The manufacturer was notified of the failure. The failure mileage was approximately 4,100.
The cross pedestrian warning activates without any object there and slams on the brakes causing severe neck problems. The cruise control doesnt disengage when pressing on brake pedal causing drive to swerve to avoid crash.
The onstar module failed. Also controlling the pedestrian px Proximity sensor and crosstraffic sensor. When driving slowly waiting a parking lot the vehicle locked up on the brakes with the warning message pedestrian alert. The area was clear. No pedestrians were in the vicinity This would be the 3rd incident 1st was cross traffic already braking while entering a light only at a speed of 15 mph. 2nd was the cross traffic and 3rd was the pedestrian alert.. We discovered the onstar module contrs all of these functions. Contacting the dealer theu stated the module need to be replaced but there is not an ETA on the part arrival as this is a common issue with all vehicles that contain. This module. We are scared it will happen if a driver pulls in front when in traffic or put us in a precarious even deadly situation
