“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. …”
NHTSA complaint #11681348, filed 2025-08“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.”

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. …”
