2024 Chevrolet Blazer EV Problems

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 XXX ~11:15 AM, [XXX] driving 2024 Chevrolet Blazer EV ~20–25 mph on/near [XXX]. 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. History of unwanted reverse emergency braking ~every 45 days: Jan 2026 near Crust Pizza Woodforest (backing up) and March 2026 at H-E-B 7988 FM 1488 Magnolia (backing out), jolting child in rear-facing car seat. Prior service at Keating Chevrolet Nov 12, 2025 (including recall/service for Unintended Parking Brake Engagement N252503010 and missing chassis harness plugs update) did not resolve unwanted braking. After June 10, AEB/front pedestrian braking/intersection collision braking were disabled as temporary safety mitigation. Vehicle removed from daily family use, available for inspection, and I request NHTSA review. Any inspection should preserve relevant braking/parking/AEB/forward collision/sensor data before any reset/update/repair.

While driving in a plaza parking lot at approximately 18mph the AEB engaged for no reason. There were not any objects near our car to activate the system. The AEB activated so quickly and abruptly that my spouse and I needed to seek medical attention due to whiplash.

The contact owns a 2024 Chevrolet Blazer EV. The contact received notification of NHTSA Campaign Number: 25V433000 (PARKING BRAKE); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

The contact owns a 2024 Chevrolet Blazer. The contact stated that while driving 20 MPH with 100 miles of charge, the vehicle stalled and shut off. The screen was black, unresponsive, and failed to start. The vehicle was towed to the local dealer, where it was diagnosed with a power module failure. The part was on back order. The electric module was previously replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was 10,381.

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.

The glare on the windshield for the Blazer EV is terrible when driving toward the sun. It makes it hard to see and unsafe.

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.

I recently purchased this EV Blazer and one day I went to charge it at a fast charging station. It would not charge and so I got it to the Chevy dealership in Yakima, WA. They told me that the battery itself had been physically damaged due to the location of the battery and it not being protected. I have no recollection of ever hitting anything and there was no visible or damage to any other part of the Blazer. It seem to me that the location of the battery and it being unprotected is a major design flaw.

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.

Blinker arm often bounces back to the opposite direction when the blinker automatically cancels once you have made your turn. As an example if I have left blinker on after I complete my turn it often bounces back over to the right side turning the right blinker for a few flashes.

See attached document for complaint.

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.

I am not comfortable with this car, I took this car to the dealership to get fixed and checked on recalls but they could not fix the most important and most dangerous recall. They worked on recall#N252492430 and recall #N242468490 from [XXX] # [XXX] . When I got there, no one gave me an update of the car they only gave me a receipt with 3 pieces of paper and that is it. What can i do in this case? I can not drive this car knowing the brakes will go out and I might have an accident and crash.

Rear suspension was always a little noisy, but ~1,850 miles the driver's side rear sounded like it was detached and breaking through the strut tower. I quit driving the car and make an appointment to drop it off at the dealership on 12/5/24. Dealership confirmed that "fasteners" were broken on the rear strut, in a place that cannot be easily accessed, and confirmed multiple times that it is definitely a problem that existed from the factory. There are two pins on the rear struts that are broken off on my vehicle, and the dealer _strongly_ advised against driving it. My car has now been at the dealership for 51 days as they are awaiting inspection by GM as well as instructions and approval to fix, and the dealership noted that they need to figure out how many cars this affects as well as what the fix will be.

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.

The contact owns a 2024 Chevrolet Blazer. The contact stated that the front driver’s side seat failed to move forward or backward. The contact stated that while attempting to move the seat, the seat failed to operate as needed. There was no warning light illuminated. The vehicle was taken to a local dealer to be diagnosed, and the contact was informed that the seat was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 11,000.

The contact owns a 2024 Chevrolet Blazer EV. The contact stated that the liftgate intermittently closed independently after opening with the fob key. The contact was concerned that he and others might be injured while standing near the liftgate when the failure occurred. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 25.

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.

Over the last month, the charger has exhibited erratic behavior, including the current jumping, the current dropping, charging interruptions, and tripping the breaker.

Telescoping adjustable steering wheel would not lock into place. If adjusted to multiple different positions, the steering wheel would fall out of position and drop in height as well as in towards the dashboard without warning. This occurred several times while driving as well as while parked. Took back to the dealership and was told initially that it was just the locking mechanism that needed to be replaced. Now the dealership is telling me that the entire steering column needs to be replaced.
