My 2021 Jeep Grand Cherokees throttle got stuck in open throttle mode and an error message came on. I pushed the brakes it eventually slowed down after a few seconds when the error message came on and eventually came to a crawl, it was stuck ⅘ of the way, but if I pushed it further it would not go. I was using paddle shifters in track mode. It has about 1,050 miles on it. So I pulled over, stopped, and put it in park and restarted and it was fine. Would this be a mechanical issue or electrical issue? And is it likely this could happen again?
