2023 Chevrolet Bolt EUV Driver Assist & ADAS Problems

Forward collision prevention system activated unnecessarily. I was already breaking and on track to stop well behind the vehicle in front of me. I had just pulled around stopped traffic in another lane, which seems to be common in all the incidents I've had like this. The safety concern is that the vehicle stopped unexpectedly, and if traffic behind me hadn't been paying attention, they could have run into me. In the past I asked a dealer to look into it, and found nothing wrong. Deactivating the system for a time, and then reactivating it, seems to improve the problem for a while.

On June 7, 2025 at 5:00pm while driving on the expressway, my car suddenly braked, jolted and skidded and I pulled over. My granddaughter was in the back seat and I thought either a tire blew or I got hit. I called my son and he did some research and found articles of this happening to Chevy Bolts euv's. They call it phantom braking. It happened 2 times before in the city and I thought I drove over something on the road. I took it into the dealer and they could not determine the problem. They said they opened a case with GM and gave me a Customer Concern Verification form to fill out if it happens again. They said if it happens again, then they will replace the forward collision module. I am terrified to drive on an expressway in fear this will happen again. I could have gotten hit if a car was too close behind me when my car broke suddenly. I nervously drive home after this event, while my son stayed on the phone with me.

The Telematics Module failed at 43,000 miles, 2 years. This shut down everything having to do with GPS, Communications, Super Cruise. I got into an accident, which I feel the car would have responded to, before the accident, if this system was working. The warning was the on star, super cruise, communications, warnings didn't work. On the dash a symbol GPS with red circle and line through it was visible. The Chevrolet Dealership diagnosed the problem and is replacing the module, at my expense. If you do a google search on Telematics Module you will find that this issue applies to all GM vehicles and failure rate is right when the manufacturers warranty runs out, 36,000 miles.

On several occasions, the car has locked the breaks, causing the car behind me to almost rear end me. The forward collision camera thinks it sees an object or another's vehicle in front when there is nothing on the road and activates the breaks for no reason. This has happened approximately 6 times while traveling anywhere between 20mph to 55mph on the freeway. I called chevy dealer and said there are no recalls or any updates that they can perform on the camera as of now. This is a huge safety issue and chevy should be issuing recalls for issue.

The contact owns a 2023 Chevrolet Bolt EUV. The contact stated that while driving at various speeds, the automatic emergency braking system engaged while there were no vehicles or objects nearby. Additionally, the contact stated that while driving at various speeds, the Super Cruise driver assistance feature disengaged unintendedly. The contact stated that upon attempting to reengage the feature, a message advising that the road lane could not be found or that the contact's face could not be read was displayed. The vehicle was taken to the dealer several times. The dealer informed the contact that the vehicle was operating as designed. Additionally, the contact stated while driving 50-60 MPH on the left lane, the Super Cruise driver assistance feature disengaged unintendedly, causing the vehicle front bumper corner to hit the wall on the driver's side. The contact stated that the driver's side of the vehicle also hit the wall and the vehicle stopped. The contact stated the front driver's side wheel and axle were fractured. The contact hit his head against the driver's side door during the incident and sustained pain, but did not seek medical assistance. A police report was filed, but the contact did not have the police report information available. The vehicle was towed to the dealer but was not diagnosed or repaired. The vehicle was then towed to Body Works on Grand, Inc.(6134 W Grand Ave, Chicago, IL 60639) to be repaired. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 27,000.

This vehicle has now suffered 5 instances of phantom braking, clear road and clear weather in 10,000 miles of use. Two occurrences within the last week despite carefully cleaning the car and sensors/camera. Twice I have nearly been rear-ended. The dealer found no issues when this was initially reported.

Forward collision warning / automatic emergency braking engaged with no hazard in front of the car. Occurred in slow, heavy traffic at approximately 20 mph. Lanes were straight (not on a curve). Vehicle in front of mine was at least four vehicle lengths ahead. Lanes to the left and right were occupied by large box trucks - I suspect they confused the system. Car has just over 10,000 miles. Vehicle briefly braked hard, which if the vehicle behind me had been following too close could have run into mine. Have not yet contacted a dealer or service center. Not inspected as no actual collision occurred. System once gave an erroneous warning of forward collision with no other vehicles on the road in the first month of service.

While using adaptive cruise control, the vehicle braked suddenly with no other cars or obstacles in view. If a vehicle was behind us, we would have been hit at 70 mph.

My husband was driving (I was the passenger). We were driving down the road normally, straight ahead,, not too close to anyone else, when suddenly the brake (or emergency brake, which is what it sounded like to me) engaged out of nowhere, throwing us forward. (My husband's foot was on the accelerator pedal, not the brake pedal.) Unlike the last two times this happened, this time the car did "beep" as if there was a potential collision, except there truly was not. We weren't going fast and had good distance from the car in front of us. Just a normal drive. Like the previous two incidents, the system corrected itself within a second or two and let us continue, but it's terrifying because the car had a mind of its own. Again, fortunately, no one rear-ended us, but it definitely could have happened if the car behind us was closer.

The car has now had five instances of phantom braking. The first time, I was in the left turning lane. A light rail type train was to the left. I was stopped waiting for the light to turn green. When the light turned green and the car in front of me started moving, I removed my foot from the brake and began to accelerate. I moved forward about 10 feet and the automatic braking system engaged at the car was stopped. There was no object or person in the path of the car. I went to accelerate again and the same thing happened. Both the passenger in the car and I were stumped. We’d never seen this happen before. The third time this happened, I was pulling into a driveway with a slight slope. There was a fence to the left and it was raining. When I was 1/2 way into the driveway, the car screeched to a stop. I’ve pulled into this driveway numerous times and this was the first phantom stop. I tried to accelerate again and it again stopped itself. Most recently (earlier this week) was the most worrisome because I was actually driving a bit faster. There were no cars, objects or people anywhere. I was going perhaps 5 mph and the car slammed to a halt. I thought the common factor was low speed and an object like the light rail or fence to the left like in the previous four instances. But, that was not the case here and it was far scarier.

While driving pulling into my driveway the vehicle emergency braking engaged causing a violent sudden stop. There were no obstructions or anything that got in the way of the forward sensor

We were driving slowly in Los Angeles traffic, trying to pick up a little speed, when the car suddenly seized up -- as it seemed to slam its brakes. We nearly had heart attacks, because there was traffic behind us, and the car behind us could easily have slammed into us. We didn't notice anything on the dash. We don't believe the car was trying to warn us about an imminent forward collision, because there were no "beep beep beeps" as there typically are when it senses a forward threat. Just a sudden breaking, and then it was fine again. Happy to have anyone inspect the car upon request, though I have my doubts they'd find anything. Note that there are already several other complaints about this car that have reported exactly the same problem. It really should be investigated!

Moving at 3mph on slow freeway offramp, my Bolt EUV suddenly braked by itself for no apparent reason. I was at no time in danger of colliding with the car in front of me. However, the driver behind almost rear-ended me when surprised by the sudden braking and sounded his horn. Control Modules scanned at Culver City Chevrolet. No Diagnostic Trouble Codes detected. Problem not confirmed by dealer. An earlier incident of emergency self-braking occurred in May when traversing a speed hump at normal speed where no other vehicles were present. These are the only two instances of self-braking, both unexpected and unnecessary, during the first 5 months/2400 miles of new car ownership. Car is available for inspection upon request.

On the freeway going 70 mph our car decided to slam on the brakes. We had it on supercruise which also uses adaptive cruise control. It was not raining, it was overcast, we were in farm country with no bridges or signs over the roadway. No cars around. It was very scary! I have 2 other cars with adaptive cruise control and have never experienced this.

The contact owns a 2023 Chevrolet Bolt EUV. The contact stated while the vehicle was in reverse(R), the cross-traffic alert system failed to alert of passing vehicles within 60-ft of the vehicle. The vehicle was taken to a dealer however, the failure could not be duplicated. The manufacturer was notified of the failure. The failure mileage was 100.

First off the Forward Collision Alert doesn't work until your about 1 to 2 feet from impact, no matter which of the 3 settings it's put on. We were so close to impact to the rear of a semi when the service tech was testing it that I was very uncomfortable. The lane assist doesn't work until you're left of center or it bounces you back and forth like a drunk drive, plus it doesn't always reconize the yellow or white dotted line. On occasion it will completely go over left of center and put you in the left lane. (It will not maintain the car in the center of the lane.) Today after service the appointment on the these problems, 7 March 2023 both the service Tech and Service manger told me they're just warnings nothing they can do about it. The manufacture sells sheet clearly states Foward Crash Alert. What good is it if your crashing when the alert goes off. It aloso clearly states on the sheet Lane keep assist w/lane departure alert. Again if your already left of center before you're alerted or corrected what good is. The Tech didn't even enter anything about the Anti collision not working but he did joke with the service manager about making me uncomfortable when we were about to collide with the semi.

This car is equipped with Super Cruise an automated driving feature that I believe had a huge part in my inability to avoid hitting a deer. There should be many more considerations and warnings to consumers to protect them. In my situation I kept driving for much longer than I should have because the strain was not so bad. But the feature does not have a feature to pull over. I had to manually pull over and it was in this short period of time where I was clearly too impaired to drive without super cruise but with it I was still fine I could keep my eyes open and on the road which was the only requirement. I was really not prepared and should have been told to make sure you get off the road sooner than you think because once you’re off the highway if you don’t have enough alertness to even pull over or in my case avoid a deer running straight toward my car. The steering feature steered me back toward the deer as I tried to steer away from it. It was running toward me so I tried to steer away to brake. In order to overpower these safety systems I needed to be more alert. Nobody talks about this and I’m normally a really alert driver that’s never been in an accident before I’ve avoided many without these safety features. I know it was my fault for being too tired, but again people shouldn’t be learning that in a life or death situation that should be explained to them. Obviously I would never use that feature until the point I was too tired like I normally do when I’m driving because like I said there is no safe way to pull over if you don’t have the alertness. I mean imagine it was a child and not a deer and I hit a child. That would be a mistake you can’t come back from and I don’t want that to happen to me or anybody else. I’m really second guessing all of this automatic driving because us as consumers have not been properly educated on how to use them safely cause I don’t think these automakers know they are in such a rush to beat each order to market it’s dangerou
