we have a 2016 chev impala with two batteries and the motor would die at stops to save fuel but it quit doing this have had it in chev dealer shop 3 times and they put new battery on helped some but quit working again will this do damage to the other battery or car. They do not know what else to do help.
it is really hard to read your post without any punctuation plus the car is still under warranty if the dealer doesnt know what else to do have them contact the zone or take it to a better dealer
