The starter and flex plate failed (cracked) on the vehicle while on the road due to the auto start stop feature. When I stopped for a red light, the car made a loud grinding noise and would not restart leaving me stranded in traffic. The 2019 Blazer has the auto start stop feature which cannot be disabled and likely results in excess wear and tear. GM updated the 2020 model to allow the function to be disabled. GM has a number of technical bulletins highlighting both starter and flex plate issues, the first being in 2020. Both the starter and flex plate failures were verified by Reeder Chevrolet in Knoxville TN. I've asked for the flex plate to be provided when repair is complete. There were no warnings via check engine lights or any strange noises prior to the failure.

While driving the Blazer the vehicle lost power. It was missing and didn't want to go. The warning lights came on. I had to call the tow truck to come pick it up. I had it delivered to the shop where I bought it. That was on Sunday, October 6, 2019. On Monday, October 7, 2019 I was called and the conclusion was made that I had a dead injector. They replaced injector #5. picked it up on Tuesday, October 8, 2019. Drove it home and on Wednesday, October 9, 2019 on the way to work, I ended up on the side of the road again. The car did the exact same thing as on Sunday. The car went down to 20 mph. I was able to limp it to a parking lot. I called a tow truck again and took it back to the shop. I am still waiting on the diagnosis as of Friday, October 11, 2019.
