I recently purchased a 03' Nissan Pathy, on the drive home for the dealership I noticed the speedometer needle would sometimes stick until either I slowed down considerably, sped up considerably or tapped on the instrument cover. Example: driving 55, then slowing down the needle stays at 55 until it finally " breaks" and goes back down to the actuall speed. Has anyone seen this before. It is back at the dealer and they say all electronic sensors are good. And of course it hasn't done it when they've had the vehicle. Thanks for any help.
