I’ve had intermittent issues where the one pedal driving feature would disable itself. Last night I narrowly avoided a T-bone collision as the OPD deactivated and as I approached a junction it took me a second to realize the car was not stopping and it was only by sheer luck that the other vehicle stopped abruptly so we didn’t collide.

The collision avoidance and automatic breaking is know. To be defective enough that employees on the forum suggest changing to alert only. But it goes off so much that I tend to ignore it subconsciously which could lead to a serious accident

On multiple occasions the electrical system of my car has gone completely haywire. Various error messages display on the dash referencing problems with almost all car systems including: high voltage battery warning, reduced acceleration, power steering failure, and others. These error message occur in conjunction with the display screens flickering, all the fixed dash warning lights coming on, and the heater turning on full blast without my input. The blinkers also stop working during these electrical events which is a safety hazard to other vehicles. I have taken the car into the dealer multiple times but they still don't know how to fix it. Software updates have not worked. I have pictures and videos of the events occurring. I have also read on message boards that other Blazer EV owners have this exact same problem.

I entered my vehicle, and began to reverse when I noticed that the backup camera did not show up. Then I saw that my instrument cluster was not appearing either. I did a reset on the infotainment and the entire instrument cluster and infotainment set of screens stayed black. I had to leave the area so I ended up driving a few miles with no gauge cluster, camera system, or dash indicator lights. Eventually this was rectified by leaving the vehicle off for several minutes, but now I fear this issue will return unexpectedly again.

The high voltage system and charging system have both failed in this car three separate times. It has spent almost 50 days in service for high voltage system issues in the 110 days that I’ve owned it. The manager at the dealership told me that a lot of the Blazer EVs that they have sold have had this exact issue and that GM doesn’t seem interested in actually fixing it. They change sensors in the car but don’t want to spend the money actually fixing the battery. Plenty of other owners online have had the exact same issue, many times in the first week of ownership, one before they even drove off the lot. There is a systemic and recurring issue with the high voltage systems in the Blazer EVs.

The emergency collision avoidance braking automatically activated for no reason. Twice it happened at highway speed, once at 65 mph, once at 55 mph. On the one occasion we were approaching a highway overpass, it was bright and sunny - I suspect the system saw a shadow that it thought was somehow going to be a crash and momentarily activated brakes. The other time at highway speeds - I didn't see anything in particular that it was reacting to. Once this happened at about 30 mph, I suspect it saw a dark patch of asphalt. All of the times was just a moment, it was kinda scarry.... glad there wasn't anybody closely following us - could have gotten rear-ended. I have now disabled the system.

Dear NHTSA, I am writing to express concern about the excessive noise generated by the Pedestrian Warning System (PWS) on my 2024 Chevrolet Blazer EV. While I understand the importance of these systems for pedestrian safety, the current volume level is unreasonably loud and intrusive. The PWS on this vehicle activates at low speeds, (below 25mph), creating significant noise pollution both inside and outside the vehicle. This excessive noise is not only irritating but also potentially harmful to the well-being of drivers, passengers, and particularly our furry friends. I have hearing aids, and it is painful to my ears! I request that the NHTSA investigate the volume levels of Blazers EV PWS systems to ensure they are both effective for pedestrian safety and considerate of vehicle occupants. They need to match combustion engine noise levels and no more. Thank you for your attention to this matter.

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.
