NHTSA complaint #11383399, filed 2020-12, 12,500 miles“I was stopped n the drive thru at in-n-out with my foot on the brake and the eco system had turned off the motor. It spontaneously turned back on without me lifting my foot off of the brake and the transmission engaged and the truck launched forward approximately 12-18 inches.
