My porsche does this once in a while but i havnt tried starting it in reverse i always run my shifter through all the gears ussually from 3 to reverse to 1 to 2 to 4 and it never has problems. try it. hope it helps.
once in about a month when i turn a blinker on the wipers turn on and my cruise controll is in working condition but my switch on the turn signal doesnt work it. and my wiper pump wont turn on even tho i got a new one. is it something in my steering column or a couple fuses i need check. HELP
