1 bad ground strap can wreak havoc on these modern vehicles, some making you think your transmission just went out and put you in limp mode. Ok on country roads but extremely dangerous on interstate highways. Yeah, we all know that, carry on.
We had the original battery in the 2012 Charger me and my ex had. What a pain in the *** with all kinds of options not working. New battery and food as new. That said, I don't use auto start, she relied on it.
