Numerous problems with 1998 Jeep Cherokee sport. During the first year of owning the vehicle the vehicle was at the dealer 12 times for rust marks on the vehicle which the dealer described as fall out and they insisted it was something the consumer had done to cause it to happen so soon, the electrical system failed, as the consumer was driving all the gauges went out and the vehicle just stopped, the air condition and radio were inoperative and still is, there was a thumping noise which was attributed to the rotors which was supposedly fixed. The most recent problem was with the power windows.
