Electrical reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

This vehicle experiences multiple recurring safety-critical system failures while driving, creating a dangerous operating condition for both the driver and the public. 1. Dashboard / Instrument Cluster Failure While Driving While the vehicle is in motion, the dashboard display intermittently shuts off completely. When this occurs, I cannot see my speed, warning lights, battery status, or any other gauges. This creates a severe safety risk because I am effectively driving without any instrument information. The issue occurs while actively operating the vehicle on public roads. 2. Navigation / GPS Location Failure The vehicle’s built-in mapping system frequently shows my location several states away from my actual position. Even though the location is incorrect, the system continues to provide turn-by-turn navigation instructions based on the incorrect location. If these directions were followed, it could cause a driver to make unsafe maneuvers or become distracted while attempting to correct the navigation error. 3. False Automatic Emergency Braking Activation The automatic braking system frequently activates even when there are no vehicles, pedestrians, or obstacles present. The vehicle abruptly slows or brakes on open roads with nothing nearby. This creates a significant safety hazard because it could cause a rear-end collision if another vehicle is following. Repair History / Ongoing Issue: This vehicle has been taken in for repair multiple times for these issues. Despite attempted repairs, the problems continue to occur. The recurring nature of these failures indicates a systemic defect that has not been corrected. Safety Concern: These failures create multiple hazardous driving conditions: Loss of dashboard information while driving Incorrect navigation location and directions Unintended automatic braking events Allowing this vehicle to remain in service with these unresolved defects places both the driver and the public at risk. Request: I am requesti

Left turn signal can activate by itself after right turn. Details: Driving and making a right turn with the right turn signal active, after the turn when the signal cancels, the signal sometimes activates the left blink-to-pass feature causing the left signal to blink 3 times. This appears to be because the turn signal arm falls too hard. When turning onto a multi lane road this causes confusion to drivers coming up behind where they think I am moving into the left lane, but I am not. GM has loaded software to reduce this but it still happens. They replaced my turn signal arm and it still happens (much less often now). I can prevent it from happening by using my finger to dampen the turn signal arm when it cancels by catching it and slowing it down. I stopped using my turn signal completely as it is embarrassing when it does this.

The glare reflecting from the dashboard on to the windshield is many times blinding and obstructs a lot of the front view. Also randomly the side mirrors tilt up while driving giving me a view of the sky but not the road behind me.

While driving the vehicle loses power to the instrument panel and gauges and infotainment system. The vehicle remains under power however the driver looses the ability to see how fast the vehicle is moving or any information as the entire dashboard loses power. The safety to both myself and my family as well as other drivers is at risk if I am unable to see how fast I am going or control any equipment in my vehicle. This is a known issue online with many other drivers of the blazer EV experiencing the same issue with no remedy from the manufacturer.

After getting the recall repaired (which I was never informed of and I had the parking brake engage as I was travelling 30 mph causing me to skid down the road) I got the vehicle back and the very next day it was the same issue and the abs and traction control light came on and it began making loud clicking noises every time I would engage the brake.

The right side tail signal light module needs to be replaced. I was having intermittent issues with the right turn signal, I took the car to the dealership and they told me that the module needed to be replaced. The car has been in the dealership since March 19th, more than a month ago waiting for the part. I contacted Chevrolet and they keep telling me that no ETA for part is available, and they do not provide any more details on what is causing this delay.

This vehicle with a total of 700 miles on the odometer, gave several warning notifications this morning on my way to work. Service high voltage system, reduced acceleration notification. I was on the interstate and suddenly became unable to accelerate to keep up with traffic, creating a dangerous situation for my safety. This is a know problem with the Blazer EV, as GM had previously issued a stop sale order in December of 2023, a supposed software update was issued and they continue to sell the dangerous vehicles, as the software update did not fix the problem as I just experienced it today, on a car I bought brand new 2 weeks ago with 700 miles on the odometer.

The emergency brakes engaging in reverse and while in drive. Not available for inspection as the vehicle is now totaled. It was involved in a rollover accident. I believe the emergency brakes caused the rollover. If the rollover was in fact due to the emergency brakes engaging, the accident could have happened on the highway, or a busier street putting several lives in danger. Thankfully, there were no other vehicles involved. The dealership as well as GM were notified of the issue. The dealership was unable to reproduce the issue, and returned the vehicle backed to us. Upon researching online, this is a known issue for the Blazer EVs. After the accident, the vehicle was towed as it was not drivable. The vehicle was then picked up by my insurance company, Progressive, and evaluated if the vehicle was repairable. It is not. The emergency brakes engaged previously to this event. Several times in reverse, then a handful of times in drive.

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.

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.

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.

Although the owner's manual specifically states "When enabled, One-Pedal Driving applies in R (Reverse) and D (Drive). This feature remains enabled until manually disabled by the driver." One pedal drive does not work in reverse. Car does not creep in reverse like an ICE vehicle, but quickly lurches backward, surprising an experienced or forgetful driver and possibly endangering pedestrians walking or standing behind the car. Dealer service has checked it and consulted with Chevrolet, who refuses to address the issue, saying the owner's manual is just wrong. The same one pedal drive verbiage appears in both the Chevy Bolt and Cadillac Lyriq owner's manuals.
