general problems of the 2002 Volkswagen Jetta

My 2002 vw Jetta tdi has many electrical problems. The one that might be a safety factor is the micro switches in the door latches. The doors with faulty switches don't know if there open or closed. When open the safety light on the door does not come on to alert oncoming vehicles that a door is open. If the switch stays on when the door is closed, the dome lights stay on until the battery is dead. The vw dealer just "jerked" me around until the warranty had expired. (fredericton vw). Since the part(s) for this repair are expensive, I feel that vw should recall all vehicles to replace the switches and door latches. Mel moir.
