2024 CHEVROLET BLAZER Complaints

The vehicle will automatically extremely hard brake while moving for no apparent reason, with no obstructions present. This problem startles driver and passenger and can present a danger to vehicle of being hit by other vehicles not expecting a hard braking situation for no apparent reason. Please investigate and make manufacturer responsible to fix the issue. Thank You

When the Automatic Emergency Braking system is enabled, it will suddenly brake when in reverse even though there is no obstacle at the back. The braking is so sudden that it is painful. I reported it to the dealership but they never got back to me about a solution. I have disabled the AEB for now.

The contact's daughter rented a 2024 Chevrolet Blazer. The contact stated that while his daughter was driving at an undisclosed speed, after driving over a small imperfection in the roadway, there was an abnormal scraping sound coming from underneath the vehicle. The driver pulled over to the shoulder of the roadway. After a visual inspection, the contact observed that the exhaust mounting bracket had disconnected. The vehicle was taken to an independent mechanic by the rental company, and the vehicle was repaired; however, the contact’s daughter was not provided with the diagnostic results. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 29,000.

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.

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.

Wipers, Yes available for inspection Wipers would not operate regardless of control speed setting while driving on interstate, could not clean windshield and visibility was dangerously diminished The windshield solvent sprayer did NOT work as well Once I parked, turned off car, started car 30 minutes later and the Wipers were back to operating normally. Not confirmed, because it happens intermittently No Inspections No warning lights or indicators

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.

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.

I was driving down the highway at 70mph using the adaptive cruise control. There was nobody in front of me, and suddenly the vehicle started picking up speed. I looked at the cruise control and it said 115mph, so I hit the brakes to override it and slow down. when I reset it for , ~70mph again it worked fine. This happened to me two other times with the same basic scenario. The speed is always over 100mph, and it always occurs when the adaptive cruise control has been in use for at least 30 minutes. I have an appt with the dealer that I bought it from to have it looked at. No warning lights and no other symptoms.

Complete brake failure 4 times in the first 450 miles. Can turns on and power brakes and not functioning. Clears after a restart.
