The serpentine belt on 96-2000 Chrysler minivans slipping off is a known issue and has been for years. Time and time again Chrysler has refused to issue a recall for it. It is due to a manufacturing defect in one of the engine mounts causing a pulley misalignment. The belt slipping off causes loss of power steering, water pump, and alternator. The power steering loss can cause a driver to not be able to correct in time and cause an accident. The loss of the water pump can cause overheating resulting in engine damage. The loss of the alternator can cause the car to eventually stop running when the battery is drained, causing motorists to be stranded. I live in alaska and I'm not always in cellular signal when driving and temperatures in the winter get down to -30 f at times. I can't wait sometimes several hours for a tow truck to get to me without risking hypothermia at those temperatures. This needs to be made into a recall so it can get fixed.
I have a 2000 Dodge Grand Caravan sport, the serpentine belt has fallen off 4 times since I have had the vehicle. The first time it came off I was going 35 mph in a residential area, a friend helped my dad put the belt back on, then a few days later it came off again going 55/60 mph, took it to a local mechanic and had the water pump, serpentine belt and tensioner pulley replaced. About one to two week(s) later the belt falls off again during excelleration to get onto an express way, this time took it back in and they replaced the tensioner itself. I thought the problem was fixed, but it happened again on August 12, 2014, it was raining and I was only going 25 mph as I turned onto my street, luckily I was able to pull into the drive way before my van started to overheat.
