2023 CHEVROLET Blazer

ON SEPTEMBER 10, 2025 THE TRANSMISSION FAILED FOR THE 3RD TIME WITHOUT WARNING. THIS TRANSMISSION ONLY LASTED ABOUT 5,500 MILES. WHEN IT FAILS, IT SIMPLY DOES SO WITHOUT WARNING. WHILE DRIVING IT WLL START SHUDDERING AND WHEN YOU STOP IT JUST WONT GO AFTER THAT. gm KNOWS THERE IS AN ISSUE WITH THESE 9 SPEED TRANSMISSIONS BECAUSE THEY ARE ON BACKORDER AND MY VEHICLE HAS BEEN IN THE SHOP FOR OVER TWO MONTHS WAITING ON PARTS. SINCE THIS IS THE 3RD FAILED TRANSMISSION UNDER WARRANTY, I CREATED A COMPLAINTWITH GM AND REQUESTED A BUY BACK BUT THEY REFUSED.

On July 31st 2025 my vehicle would not sift out of first gear. I had vehicle towed to Kelly Chevrolet in [XXX] . After a failed repair attempt on August 18 2025 have been waiting on back ordered valve body part number 24045659. No eta on this part even though a transmission replacement would resolve but dealer refuses to replace. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Since I’ve got the vehicle i experienced issues with it not going in drive or reverse sporadically. I was air to obtain this in video and show it to the dealer for the first time Dec 2023. In addition and overtime it’s seems this issue may go hand and hand with the lane assist issue that had been known on Chevy models where they either don’t work of they don’t recognize the lanes correctly and they pull although your in the correct lane.i have specifically taken the car in on 3 or more occasions about it disengaging and not driving forward or backwards. More recently it started to seem as if while u was actually driving the car did not want to accelerate forward and then while trying to accelerate the steering wheel pulled and caused the car to spin out of control on the freeway. The car was just in the shop from End of April till May and the issues are unable to be duplicated so I just keep getting pushed off with the car. The car radio constantly malfunctions and glitches i several different forms, black screen no sound or not allow Bluetooth capabilities. My most main concern is this power train issue and me getting stuck with a car that is going to be it of warranty and the issue has never been resolved even though I have showed the dealership a live video of the occurring issue that there is something wrong here.

Thermostat not working. Causing fan to run as if the vehicle is overheating

I am writing to inform the appropriate authorities of the issues that I’ve continually had with my 2023 Chevrolet Blazer. It has come to my attention that the aforementioned vehicle will need a new transmission and possible engine repair currently totaling at just over 6,000 dollars in repair costs. When I was provided with the total repair cost I was informed by the certified service representative that this was a common issue for the Blazer model and that GM was aware of the ongoing issue. I’ve reached out to GM with my concerns regarding this vehicle and the fact that this is an issue that has in prior dates prompted recalls for blazer models from the year 2020-2024. I have because of the transmission defects/ failures been stranded and unable to shift gears required for proper motion of the car. To which I am sure you can understand the public safety risk of an inoperative transmission. I have taken the car in for service concerning the transmission on 3 separate occasions within the last 10 days and was told by prior service technicians that “ No problems were visible” leading to the total breakdown of the transmission. I reached out to GM and told them of my wish to return the leased vehicle early due to my fears of now driving and operating the car and was told that I was not eligible for a buy back. GM is maintaining its stance of no liability and I am seeking outside help from this governing agency to ensure that repair costs are fully covered for this defective product.
