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 Jeep and weld in new frame rails and other support and reattach detached suspension and other necessary equipment.

My 1999 Jeep Cherokee shakes violently at speeds over 50 mph when I hit a slight unevenness in the road. I've had my Jeep inspected by a Jeep dealer, paid to repair the problem, and it still remains. This is a well-documented, repeated issue, that I, and many others have experienced, driving Jeep. It's been reported on by both abc news (abc7news.com/archive/8768540/) and fox news (www.foxnews.com/leisure/2012/07/09/what-need-to-know-about-Jeep-death-wobble/) and acknowledged by Chrysler in a technical service bulletin. I went to my local Jeep dealership, Chrysler technical service bulletin in-hand, spent $1,000 to replace my entire steering system at their behest to correct what they claimed was causing the violent shaking I experienced when driving my Jeep on the highway, only to find, post-repair, after hitting a minor seam on the highway at a speed of 52 mph, that the "death wobble" was worse than ever, and my Jeep was totally unsafe to drive. The fact that no one has died yet from losing control when their Jeep starts violently shaking while they're speeding down the highway (that we can prove) due to an obvious design flaw in these vehicles is a shameful reason for the NHTSA to dismiss this issue. I've been very lucky, so far that other drivers have noticed me rapidly reducing my speed in time to get out of my way. I've been lucky that road conditions allowed me to slow down or pull over. I've been lucky to be going slow enough to reduce my speed before I lost control. I've stopped driving on the highway, stopped driving long distances, and plan to trash my Jeep as soon as possible, though I just invested $1,000 in its repair. Is that right?
