I purchased a 2000 Mitsubishi Galant brand new in June, 2000. About 18 months later, my car would immediately stop running. All systems would die. My Mitsubishi dealership attempted different fixes on many occasions, only to have the problem occur again. Finally, my car was sent to a master mechanic at another dealership who diagnosed the problem as something to do with an electrical regulator or switch. To my recollection, the switch could only carry a 10 amp load, and was getting shorted out because it needed more capacity. The previous work at the other dealership did not fix the problem, although the resetting of the system made the car able to function again until another occurrence. The master mechanic at the dealership installed a 50 amp switch and mentioned that it was way more than I would ever need in this car. My car has operated for over 4 years without incident. Yesterday, a small fire started on the piece that I believe may have been part of the fix. While I'm unsure how related these incidents are, I am concerned about other Galants on the road.
