Went to drive it one day and found the speedometer was pegged all the way around to the other side of the peg. Dealer said it need reset/recalibrated. Ocasionally since then, When I start the car, the needle jumps up to varying speeds, say 40 or 60 or 100, then drops down to 0 and operates normally as I drive. I tried the odometer diagnostic (hold in the trip odometer with the key off - nice light show!) No difference, still jumps up.
Anyone had this kind of problem? Ideas?
TIA!
