My 2012 Ml350 has been glitching since I placed it in the garage this winter.I tookit out for a ride this spring and First the car detector went out on the passenger and driver side then the wipers went out. I made a appointment to take it in before rain came and i got a alert on the dash saying take straight to dealer dont shift gears. Started up like normal so I take it in the next day. I had a diagnostic exam done on it and nothing came up. Been driving it for the last 3 weeks and nothing until the wipers went out again. I take it in again and they change the fuse and give it back and to me. When I get in it says dont shift gears take straight to service center again while im still in the dealers lot. They take it in and now my truck wont start or shift gears. Mercedes dealer says It's not the sam, battery or backup battery, or fuse so what could it be? Mercedes dealer has no clue and diagnostic is coming back good! Any idea anyone? Has anyone else seen or had this happen? If so what is the solution?
