We replaced a worn serpentine belt in 02/09/06. On 9/14/06 belt fell off after driving through a couple inches of standing water. Had the car towed to a service station. They put belt back on and checked pulleys and tensioner. Again on 10/11/06, after driving in the rain, I went through a small puddle in a parking lot, at just 5 miles per hour, the belt came off. Had the car towed again and service station checked car over. Could not find a reason why the belt came off, but they replaced the belt with another from a different manufacturer. I don't know if this will help, but after reading other comments I believe this is a flaw specifically with Dodge Caravans. We have also had the tie rods replaced twice, a broken trans-axle and sway bar, a wiring problem that caused the lights to flash on and off and the locks to jump up and down as well as numerous other small problems and recalls. This car also eats through brakes. Thank goodness we have AAA. We will never buy another Dodge car.
