i drove a friends car in to have the device removed, before i got out of their lot, the car started overheating. i checked water reservoir, and radiator, did not find any problems. car ran hot off and on for the next 20 miles. when i parked it and put his keys in his office and left, the car started on its own. the remote start/stop and the stop button on inside of car would not turn motor off, car was steaming when my friend got there and he could not turn car off, i had him pull fuel pump relay to stop it from running. do not know how much damage was done to vehicle yet. this happened in conroe texas.
