On multiple occasions this vehicle has accelerated without pushing the gas pedal, with no cruise control option, it's unsolved by multiple mechanics. Sometimes the brake works while it's happening, sometimes it doesn't, the most recent time I pulled into a parking lot where I had to hold the brake down to shut the car off, I could smell the transmission, I turned vehicle off, turned it back on and it went to over 5 RPM still, turned back off, sat and waited, it was 2am so I couldn't call anyone. After 10 minutes it finally went back to normal. That was the most severe, it's had slightly similar issues at least 4 times. First mechanic said it was a cruise control issue, then I told him I was leaving since the vehicle doesn't have cruise control at all. Don't want him working on it. 2nd one ran computer check, no issue found. Hopefully gm recalls this before it kills someone. This car has had many issues me and my father could fix, ignition switch, wiper blade transmission, coolant light but this one isn't easy.

Most serious occurrence, car accelerated, brakes had no effect (pushed to the floor), ran red light, went off road, slammed transmission into park to stop. Shut off car, then started it again, and it ran normal. Took car to mechanic. No computer codes. Nothing mechanical was found to be wrong. This is an extremely serious safety issue due to the inevitability of a collision with something or someone.
