I bought the vehicle on May 27, 2021. I filled the tank with 87 octane on 3 separate occasions between May 27 and June 4, 2021.The engine (6.2L V8 L86 EcoTec) shut off during a trip on May 31, 2021. I was pulling into a restaurant and there were no indicators of any issues. While pulling up into the drive thru, the engine lost power. No Check Engine Light appeared at all. On a second trip (June 6, 2021), the engine again lost power while coming off of a highway exit. This time, I experienced loss of acceleration and then the vehicle shut off as I pulled into a parking lot. Both times I had to put the vehicle into park, shut off and then start back up. Again, no Check Engine Light. I drove the car to an auto parts store to buy a fuel additive. It was driving roughly at this point, but as I pulled into the parking lot, again a loss of power from the engine. It never started back up. Each time the vehicle shut off, I was driving it, not parked or stopped. There were also no indicators of any malfunction.

This is an exhaust fume related complaint that is also related to an electrical component failure of the rear hatch locking mechanism. When the rear hatch locking mechanism is not fully engaged the liftgate is not completely closed allowing gas fumes to enter the vehicle and it has a really bad exhaust fumes smell..... the gas is entering the vehicle co carbon monoxide hydrocarbons and methane gas CH4
