Just picked up a 2017 155 ES (sisters new ride) and the guy was saying the dealer told him it'll kill the battery if the key is left on. Any theories?
It will if you leave it on long enough with the PIDD gauge. Not sure how long that will take but leaving it on throughout the day while you are using it, I am sure it wouldn't hurt the battery at all.
