While driving, the damper pulley seperates and the power steering fails along with the water pump and the alternator. This damper as it is called is a device that drives all the belt powered devices on the engine. I asked the dealer if there was a recall on this and the reply was no. How can a power steering failure not be a recall? when you are turning and the power steering fails I would say the majority of drivers would not be able to steer the vehicle out of this situation. Look online and view all the places that list this problem. This is a big safety issue the vehicle steers very hard and is difficult to control.
