One problem related to seat broken has been reported for the 1998 Jeep Grand Cherokee. The most recently reported issues are listed below.
I have a 1998 Jeep Grand Cherokee and it seems the driver's side seat has become broken at the base and now wobbles and is just about unusable. Upon further inspection and online research it appears this is a very common problem with these vehicles. The Jeep dealer will want $400+ to repair this. Since these seats break while driving and thankfully for me I wasn't involved in an accident I can't believe that there has been no kind of recall on these. The steel used for these parts is very cheap and thin and break way too easily.
