The electronic charge port door locked up, which completely prevents access to the charge port unless you break the panel off. This component breaking is commonly-reported and Chevrolet does NOT offer a mechanical alternative. Repairs are covered by warranty, but when the warranty expires, I presume they will not cover it anymore. In that case, litigation might be necessary.

The Charging Port Door and assembly broke during a public charging station while on vacation. I had to manually pull it down which stripped the plastic gears. The door had been previously aligned because it was not flush with the body under warranty. This overcomplicated mechnical, electrical door is a subject of numerous complaints on blogs. It can be stuck causing the inability to charge the EV, leaving people stranded. Before I took it to the dealer it was hanging off the side of the vehicle which causes a safety issue and could be torn off at a car wash getting water into the high voltage electrical socket. This occured while on vacation under the 36K bumper to bumper warranty but couldn't get it into the dealer until 36.5 miles and I face a repair bill of $674.77 for something that is poorly designed with numerous failures and had been already addressed under warranty.

Since picking up the car almost two years ago the battery cooling fans have been actively blowing shredded internal insulation, forcefully discharging mass quantities of airborne fiberglass-like micro-fibers both internally into the cabin and externally into my residential garage and home. The vehicle is completely intact, unaltered, and available for immediate federal, independent, or manufacturer inspection upon request. My safety and physical health were put at severe risk due to chronic inhalation and skin exposure to high volumes of airborne, jagged, fiberglass-like microfibers blasted directly into the passenger cabin and my residential garage. This heavy environmental particulate exposure triggered a severe, ongoing escalation of my pulmonary disease that required heavier high-tier medications and caused a violent flare-up of an underlying autoimmune condition. The problem has been reproduced continuously and confirmed by my residential building's professional maintenance team. They conducted an official environmental inspection of my apartment, formally concluding that there is no structural or building source for the material, isolating the vehicle as the sole point of origin. The vehicle has been evaluated by General Motors' corporate division. Based on a plethora of underlying mechanical and safety failures, GM has formally acknowledged the vehicle's defective state and has officially authorized a statutory Lemon Law buyback. There were no digital dashboard warning lights or error messages prior to the issue. The initial symptoms appeared immediately after delivery in March 2025, presenting as an unidentifiable, aggressive gray/white fibrous dust coating the vehicle interior, clothes, and garage, which worsened exponentially over the timeline of vehicle ownership as the something continued to disintegrate the internal insulation panels. This was notified to Chevy almost immediately after picking up the car. I have photo and video showing the issue.

Auto hold was on, radar cruise control was set and as I was merging in traffic a sharp smell of burning started. The cruise control refused to disengage until I parked the car in garage. Eventually burn smell ended but seems like brake was stuck while acceleration causing a burn smell. It seems like brake could get stuck to wheels perhaps when auto hold is on even when driving? Auto break hold is a feature which keeps the break on while car is stopped.

This morning, I stopped to open the gates at work, car was idling. When I got back into the car, put it in drive and started to slowly move forward the FORWARD COLLISION SYSTEM slammed on my brakes and lights flashing on my dash. I backed up...there was absolutely nothing in my way. This has happened numerous times, different places and while turning a corner at a very slow speed. Never nothing in the way. Will definitely be taking it in to have it checked now.

On October 2, 2026, while driving my 2024 Chevrolet Blazer EV AWD at approximately 55 miles per hour, I approached a stop sign while traveling downhill on a wet road. I had let off the gas and had slowed to about 35 mls per hour before I applied the break. The road was wet from rain, but I did not believe the vehicle was hydroplaning. They rain had stopped and roads were only moderately wet. I applied the brake pedal normally and continuously held the pedal down. I did not pump or release the brake pedal. The vehicle appeared to activate ABS. I could feel what seemed like repeated braking and releasing/pulsing while I continued holding the brake pedal down. Despite continuously applying the brake, the vehicle did not slow and stop as I expected and continued moving toward the stop sign. The car continued through the stop sign and the brake failure almost caused me to hit another vehicle. Once I was past the other car I turned onto Lakeview Heights and drove at about the same speed (35) and it did the same thing at the next stop sign. I did not intentionally test the ABS or attempt an emergency maneuver. This occurred during normal braking for a stop sign. The vehicle was being driven in Sport mode at the time. I subsequently took the vehicle to a Chevrolet dealership for diagnosis. The dealership performed diagnostic testing and reported that they found no diagnostic faults/codes. The problem was not reproduced during the dealership inspection. I am reporting this because I experienced an unexpected loss or significant reduction in braking effectiveness while the brake pedal was continuously applied. I am concerned about a possible intermittent braking/ABS/brake-assist problem.

The plastic cover on the shark fin antenna has fallen off the vehicle twice now. The second time was just 12 weeks after the first one was replaced at the dealership. The part fails because the plastic clips that hold it to the base are brittle and are easily damaged by the high speed air dryers in car washes. My concern is that if the clips get weakened in the car wash and then the plastic cover separates from the base while driving at highway speeds, there is a very real potential for this part to strike the windshield of the car following my vehicle. The part in question is GM Part Number 26537604. GM has issued a direct replacement to the original OEM part number, GM Part Number 26512283 which presumably has reinforced clips to prevent this problem.
