Suspension
Filed Jan 21, 2025AL

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.

Visibility/Wiper
Filed Jan 3, 2025IL

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.

Service Brakes
Filed Dec 12, 2024FL

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.

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

Fuel/Propulsion System
Filed Dec 4, 2024MI

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. In 6 months of driving, I have had no less than 4 separate experiences in which the AEB system engaged when there was not a vehicle or pedestrian infront or around my vehicle, engaging a full locked braked at speeds between 15 - 25 mph.

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.

This may or may not be a true safety issue depending on definition. The charge door will not open some of the time. It starts to open and then closes right a way. Depending on where you are this could be a safety issue in that you could get stuck somewhere not close to any kind of service to get the door open. You could just be in a place that is just not safe to be stranded for a period of time. This problem is preventable. I my case it appears to be dust getting in a switch that causes it not to lower when the door starts to open. It takes me put to 20 times so far to get the door open when I am home with plowing air in side the door during the short time it is partly open. You will find many variations of complained on the issue on the Blazer EV Forum. Here is an example. [XXX] . I am not aware of GM recognizing this problem. This has happened to me 3 times now while at home. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Forward Collision Avoidance › Automatic Emergency Braking
Filed Nov 6, 2024TX

Automatic emergency braking engages violently on occasions when there is no obstruction present. It has left me at times with my vehicle stationary half way into a high speed traffic lane with the parking brake engaged. The time it takes to disengage the brakes leaves the vehicle in a dangerous position in the roadway.

The collision avoidance and automatic breaking is know. To be defective enough that employees on the forum suggest changing to alert only. But it goes off so much that I tend to ignore it subconsciously which could lead to a serious accident

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

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 Lithium-Ion Battery is not performing as expected. An issue has been detected in the Onboard Charging System which manages your vehicle's battery pack charge level.

Forward Collision Avoidance › Automatic Emergency Braking
Filed Aug 21, 2024WI

The emergency collision avoidance braking automatically activated for no reason. Twice it happened at highway speed, once at 65 mph, once at 55 mph. On the one occasion we were approaching a highway overpass, it was bright and sunny - I suspect the system saw a shadow that it thought was somehow going to be a crash and momentarily activated brakes. The other time at highway speeds - I didn't see anything in particular that it was reacting to. Once this happened at about 30 mph, I suspect it saw a dark patch of asphalt. All of the times was just a moment, it was kinda scarry.... glad there wasn't anybody closely following us - could have gotten rear-ended. I have now disabled the system.

Dear NHTSA, I am writing to express concern about the excessive noise generated by the Pedestrian Warning System (PWS) on my 2024 Chevrolet Blazer EV. While I understand the importance of these systems for pedestrian safety, the current volume level is unreasonably loud and intrusive. The PWS on this vehicle activates at low speeds, (below 25mph), creating significant noise pollution both inside and outside the vehicle. This excessive noise is not only irritating but also potentially harmful to the well-being of drivers, passengers, and particularly our furry friends. I have hearing aids, and it is painful to my ears! I request that the NHTSA investigate the volume levels of Blazers EV PWS systems to ensure they are both effective for pedestrian safety and considerate of vehicle occupants. They need to match combustion engine noise levels and no more. Thank you for your attention to this matter.

Service Brakes

While this vehicle was in motion the brakes suddenly stopped working. The brake pedal went to the floor with no braking. The screen read brake assist failure. Safety was at risk due to being unable to stop the vehicle until it slowed itself down. This could have resulted in a fatality. The vehicle is available for inspection upon request. The vehicle was towed to the dealership today and no answers have been provided. There were no symptoms or signs prior to the total brake failure. Other messages on screen read: one pedal driving disabled, parking brake disabled, rear parking assist disabled.

Fuel/Propulsion System
Filed Aug 5, 2024UT

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.

Ecs failure, brake assist failure. Car upon starting would not brake. Gave above stated error codes. Restarting car resolved issue temporarily. Video available of incident. Braking did not stop vehicle

Steering
Filed Mar 26, 2024CA

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.

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.

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.

Vehicle Speed Control
Filed Nov 30, 2023NM

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.

Reading these

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
