Owner reports

Selected complaints filed with NHTSA by 2024 Chevrolet Blazer EV owners, lightly cleaned up (personal details are redacted by NHTSA).

There was a wreck up ahead, and two tow trucks with their emergency lights flashing were blocking the left two lanes. Traffic was stop-and-go due to the existing wreck. I was traveling in the lane to the right of the tow trucks as I approached. I stopped about 1-2 car lengths behind them. When traffic started to move, I began to move forward and advanced about a car length when the automatic emergency braking (AEB) activated and slammed on the brakes, even though the path in front of me was clear. The person behind me rear-ended me. Luckily, no one was physically hurt, but there is damage to our car that now has to be repaired, along with all the headache that brings. If this had happened at higher speeds, it could have resulted in serious injuries. My family's safety and the safety of others are definitely at risk because of this phantom braking. …

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. …

My son was driving in stop and go traffic on I-95 and he rear-ended another car. No safety features activated: i.e. dash warning lights, audible noise, auto breaking. Last week I was at teh dealer for the recall that effected the Emergency Breaking system. Talking with the dealer some updated turns the auto system off, or otherwise adjust the settings that I have prior. Backing out of the driveway the car lock up the breaks when it sees my trash can, but not on the highway? The dash warning lights randomly light up with nothing in front of me. I know the system does not prevent every accident, but it seems to pick and chose what it warns about. It is more a hazard then a help in its present state.

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. …

I am reporting a potential safety defect involving unintended automatic emergency braking/forward collision warning/brake-control behavior, reverse automatic braking, parking brake behavior, and driver-assistance/sensor calibration. Incident [redacted] ~11:15 AM, [redacted] driving 2024 Chevrolet Blazer EV ~20-25 mph on/near [redacted]. Vehicle displayed red collision alert and abruptly braked hard although the lane was clear; only a car was parked in a driveway on the right. Sudden braking created serious risk of rear-end collision/loss of control. Vehicle used for family transportation; toddler (~30.8 lb) had been in vehicle ~10 minutes before and family includes blind/visually impaired passenger. …

I was pulling out of my parents' driveway with my sister, who is almost 7 months pregnant in the passenger seat. Before we could get down the driveway, my car VIOLENTLY slammed itself into park to the point that I was convinced I had to have hit someone. No warnings no nothing, just WHAM, causing my lower back to feel tweaked now. After jumping out and seeing nothing, I immediately brought my car to the dealership for inspection. When I arrived, I was told that the sensors are just too sensitive, and the gentleman helping me also has the same vehicle. He said his wife hates the car and turns off all safety features in order to drive the car. You want me to turn off all the safety features to prevent a crash because it is turning itself on and could cause one? …

While driving, most often at dawn/dusk and commonly with cruise control engaged, the vehicle will falsely detect a vehicle ahead when none is present. It then triggers sudden Automatic Emergency Braking along with a crash/forward-collision indicator, causing an abrupt speed drop of 15-20 mph. This is a major safety concern for my family and me while commuting in our family vehicle. If a vehicle behind us follows too closely and does not brake as rapidly as this faulty feature activates, it could cause a severe rear-end collision, or the driver may swerve into the other lane and collide with other vehicles to avoid hitting my vehicle, which has suddenly decreased speed. Other safety concerns related to this faulty braking feature include passenger whiplash and strains when the vehicle suddenly decelerates, instability on wet/snowy/icy roads, and the loss of an important safety feature. …

This vehicle massively underperforming based on what was told to me at the time of sale (250-300-mile range), I have never come even close to that range. I am averaging about 125 miles using about 70% of the fully charged battery. I WAS informed that during colder temperatures I would experience faster battery degradation but it was not mentioned that it could be as dramatic as losing 50% of my range. I feel the mileage has been massively inflated to seem better situated to compete in today's EV market at the direct expense of consumers. In addition to the blatant falsehoods I have been told, the automatic emergency braking is seriously dangerous and primed to get people killed. …

I've been in pain for 3 days since the last time my auto braking slammed on the brakes. The situation this time was in the school pick up line, where there are 3 rows of cars and I was in the middle lane. This is a very slow progressing line bc each lane has one car move forward at a time and we then move forward and stop It slammed on the brakes so much harder than I would even have been braking in that scenario and I thought I'd been rear ended. It's happened another time when I was in moving traffic and created a very dangerous situation which fortunately we did not end up causing a crash. I'll be disabling the feature immediately as it's much more dangerous than useful and I am in so much whiplash pain this time around it's insane

I have had the car for 3 weeks and twice it has slammed on the brakes for an instant at slow speed. Both times I was at least 20 feet behind another vehicle travelling at less than 10mph when the brakes locked up for an instant throwing me against the seatbelt very hard and bringing me to an emergency stop. The first time the stop was so hard I thought the car behind me had hit me but it had not. I thought maybe it was the emergency braking but there was no alert or warning as there usually is when the car warns me of possible collision. The last time I contacted OnStar and asked the run a diagnostic which they said came back with no errors. I have not taken the car to the dealer since i cannot reproduce the problem.
