After buying my Caravan in 03 I did have to rebuild the starter solenoid, but other than that I've had regular maintenance done on it, which of course is expected. New tires, brakes, radiator and transmission flushes filters etc. The only unexpected problem was with the serpentine belt, but I think the mechanic may have been the problem when I had to get a second one 14 mos. later. At that time I had to replace the tensioner which may have been the cause of the second serpentine. I've been very happy with this car. No car is going to be problem free if you don't do regular maintenance. And I'm still driving it and going to pass it on to my daughter.
Reliable, comfortable with a good ride.
Perhaps rechecking the serpentine or tensioner problems if others have had the same problem.
