This has happened a few times now. First time at a stop light, and most recently while coming down a hill. All of my needles drop and I get no response from the engine, brakes and power steering work for a little while and then they cut out. I pull over to the side of the road, turn it off, sometimes it turns back on immediately, other times it will do the same thing needles go up and back down. Any suggestions?
sounds like a loose connection to the computer (or body control module if it has one). Unless this is a known problem with this model, I think you are going to need a specialist on this one. Good luck.
