What owners report
This is the 2nd time I have been left stranded unable to charge my vehicle due to the charge door malfuction on the vehicle. This is a safty issue due to the fact that if you are unable to charge the vehicle, you can get starnded somewhere unsafe putting yourself and family at risk. This charge door failure has happened once within 8 months after purchasing the vehicle, the charge door was replaced under warranty back a year ago. Now its has started to bind up and not open leaving me unable to charge my vehicle. I have taken the vehicle back to the dealership and they had to special order the part. Currenty I have not been able to charge my vhecile properly. I have to forcefully open the charge door causing more damage, until the part is replaced. Please look into this issue, I have contacted other Blazer EV owners and have found they too have had the same peoblem.
"While attempting to merge onto a high-speed freeway on-ramp, the vehicle suffered a sudden and catastrophic loss of engine power, rendering it unable to accelerate and creating an immediate life-threatening safety hazard. The vehicle was restarte and driven home, where an onboard diagnostic check revealed an emissions system failure. The dealership later confirmed that BOTH close-coupled catalytic converters on the 3.6L V6 were damaged. The check engine light was a solid light. Not flashing.
I purchased this car in May 2023.Since day 1 one the car stalls after filling and out of nowhere. Can be sitting still or going down the highway and highway sped. I took it on snd they could not find anything. Was told to keep track of when it happens. After almost being rear ended several tons and being put in extreme safety I called them and took it back in . They have now had since 9/21/2023 saying they're some kid of valve problem in the gas tank. So I am paying for a brand new car that is unsafe to drive and is at the dealer for who knows how long .
Engine light on caused by emission system failure. Sensor unable to be changed until recall. Remote start unavailable while engine light is on. Had issue. Looked at four times at dealership. No correction taken.
Increasing speed by itself, let foot off gas pedal and gas pedal sticking, 1st time I tapped brakes and it quit. 2nd time it did not. I had to slam brakes and hokd until the point they had overheated and smell burnt and filed a separate complaint for that today. Gas pedal sticking and self accelerating. Pedal to the floor accelerating. I do not drive like that and scared the hell out of me. I bout it 5 days ago from a Chevrolet dealership. I'm tired of rip offs. Next one best be brand new and they reimburse me for outside mechanical I inspection period. Bc I trust no dealer now. Went from 7p to about 95 in 10 seconds for 10 min. Not sure what braking did bx I coukd care less about the phone whike I am trying not to hit cars in front of me literally almost jammed an 18 wheeler and moving truck with me pushing the brakes as gmhard as I could.
Two different events, first on the highway press the accelerator to pass, and the accelerator stuck tried to tap the brake did not change, had to repress the accelerator for it to return to normal. Second event pulling the car out of garage, to park in the driveway, when stopped to shift into park, the accelerator was stuck and the motor starting revving up, this time, I just turned the engine off. Also there is nothing to interfere with the accelerator, such as floor mat carpet nothing. My daughter has 2021 Blazer she said the same issues. I know this is just hear say, but on the local news, a lady's car ran out of control and ended up on the railroad tracks, she just made it out before the train hit her car, police report stated she was having problems with the accelerator, another GM product in the same year as our car.
On Friday, April 28, 2023, at about 11:30 am, my car, died as I was driving it out of the grocery store parking lot; luckily, it didn't happen as I was crossing the busy highway. I attempted several times to restart it, with no luck. There were no warning lamps, messages or other symptoms of this problem. The vehicle was in the middle of an aisle, blocking the aisle and many cars in parking spots, so I managed to get it into neutral and it backed around into parking spaces where the left rear quarter stopped against the front tire of a Ford F-350. I was actually thankful for the truck as I had no steering or brakes, and I was on a slight hill heading towards the road. I had it towed to the dealership, which was unable to tell me what the problem was before I obtained a ride home at 3:30 pm and that they would call me when they had it figured out. …

Vehicle description: 4-door, 4-wheel drive and all-wheel drive multi-purpose passenger vehicles. During development testing, the prop shaft contacted the inboard side of the fuel tank allowing fuel leakage. This leakage was in excess of the amount permitted by FMVSS 301, "fuel system integrity."
Remedy: Dealers will install additional shielding of the fuel tank. This will be added without removing or disassembling the fuel system.
