One problem related to power train has been reported for the 1998 Plymouth Voyager. The most recently reported issues are listed below.
It is June of 2003 and the car is currently in the shop again for the transmission problem. It has had a power steering pump failure, serpentine belt failure times 5 and now a computer problem. I have contacted chrystler corp at least 5 times regarding the problems with this car. Their answer is well, if you don't like the care trade it in.
