I have no clue honestly. I just know mine has done it. Sometimes, it’ll even start working the wipers and have the high beam lights come on. I think it’s because since 2006, Chrysler has been having the PCM monitor electrical circuits and it’s tripping out when it sees a lose ground or a barely touching tin heat shield
