The Blazer EV 2024 completely SHUT OFF while I was driving at an incline while motorist were accelerating behind me I was about .05 miles from the freeway where I was headed delivering the vehicle due to warnings firing off the day before the incident there was also a significant drop in Battery from 80% to 73% within a 5 mile drive. I was unable to connect to OnStar unable to put Hazards on , it started upon its own with multiple warnings and was non operational however I was able to reach to on Star who sent police and a tow truck to take to Camino Real Chevy. It was terrifying and to think I was almost on the highway! This is a FATAL SAFETY CONCERN. The GM never contacted me regarding the incident . I leased it on 11/01:2024. It was towed in non operational on 11/22/2024. It has been in the service Department since with no response as to what is going on with the vehicle or any attempts in appropriately rectifying a SERIOUS SAFETY DEFECT in the vehicle they sold me. There was NO warnings that came on before the vehicle shut off. The vehicle skidded forward I was thrusted forward . I am terrified to be placed back into this defective vehicle . I do not wish to allow this to occurred once or twice more to be considered a lemon . My LIFE AND OTHERS ARE AT HIGH RISK for a FATAL INCIDENT to occur .. I have photos videos and have filed complaints to GM Corporate ,BBB AUTOLINE Consumer Affairs , and the Attorney General of California.

There is an interment issue with my passenger, rear turn signal. Once activated, it will flash three times, and then display a "Check Right Rear Turn Lamp" message. My front and mirror light still flash, but flash rapidly to indicate an issue with the rear signal. The rear signal does not flash, but periodically will flash quickly for 2-3 flashes and go out again. The dealership stated it "...could be a list of things..." and are currently trying to find a resolution. The vehicle had a stored "low amperage" code when the dealership pulled the codes. This first happened early morning on 11/13/24 and again happened early morning on 11/14/24. Obviously having an interment rear turn signal is a safety issue.

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 High Voltage System failed three separate times within the first 3 months of ownership. Has spent total almost 30 days in the shop getting repairs. It happened at 400 miles, 800 miles, and 2200 miles. The car was unable to charge, unable to drive at full Highway speeds, and was a safety hazard because it could shut down at any moment according to the manual. The last time it happened was while I was driving home from a work trip. I had to drive 100 miles in 100° heat without functional AC and at limited speeds, hoping that the car wouldn’t shut down on the freeway in the middle of nowhere because the charging system failed while I was charging to complete my trip. Fortunately I made it home with 2% battery remaining, but if my house was another 10 miles away, I would’ve been stuck on the side of the road. The Blazer EV is a safety hazard, and multiple other people online are reporting similar problems enough that it could warrant a recall.

I had problems with my 2024 Chevrolet Blazer RS EV since the first week I purchased it a few months ago. The display would go blank while driving. I was unable to turn the vehicle off due to the controls not being accessible on the display. There is a grinding noise inside my dash and the service vehicle soon light on. The climate controls are unavailable resulting in high heat on defrost. There is a vibration periodically when driving on a smooth road. I have brought the car to the dealership several times and it has been there this time for almost two weeks. They are not able to address the issues stating that parts are on back order. My complaints to GM have not resulted in my request to return the vehicle for a full refund. The GM concierge has called me four times and keeps telling me they will need to call me back after asking questions I have already replied to. GM put a stop sale on this vehicle after selling any about 500 and they have not addressed my concerns.

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.
