One problem related to front suspension control arm has been reported for the 1999 Jeep Cherokee. The most recently reported issues are listed below.
My 1999 Jeep Cherokee uni-body frame is so rusted out underneath it is a hazard too drive, there is nothing else wrong with it. Specifically, but not limited to, control arms are rusted out and detached and frame is so rusted they can not be reattached. It seems it is very common for Jeep grand Cherokee uni-body under carriage to rust out and become a hazard with control arms detaching and vehicle becoming unsafe to drive. This is predominantly a problem in northern part of us. However, these are vehicle people buy to drive on bad roads so they should not deteriorate and become a danger to drive. Chrysler should be required to recall these Jeeps and weld in new frame rails and other support and reattach detached suspension and other necessary equipment.
