2023 Chevrolet Blazer owner complaints

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.
