Frame And Members problems of the 2007 Jeep Wrangler

When driving my 2007 4-door Jeep Wrangler on the interstate 4 weeks ago I noticed that when I hit a hole in the road or a bump the entire vehicle shook, causing the steering wheel to shake back and forth causing me to almost skip lanes and almost hit a semi truck in the next lane. The next day I called the dealership that I purchased this vehicle from used about 5 months ago (10,000 miles ago). I have made 3 trips to the dealership in the past 4 weeks and the shaking has become worse. The last 2 days while driving to and from work, I literally thought that the right front tire was going to come off or that the frame was going to brake! I pulled off of the interstate many times on my 30 mile trip and didn't drive over 40mph. I asked the mechanic at the dealership to drive the Jeep with me on the interstate today. He said that he has no idea what is wrong but it felt like the entire frame is violently shaking. I feel very unsafe driving this vehicle as I am unable to control it when this occurs. I should mention 2 more things. . . 1. This only occurs when one side of the vehicle hits a bump, not when both tires hit at the same time, like hitting a pot hole with left tire. 2. Many owners of this exact make and model are having the same issue. I have been looking on-line and there are multiple site with hundreds of people who, despite spending a lot of money replacing part after part continue to have this safety issue. I have received a recall notice about the lack of temperature control of the cooling system but Chrysler has not addressed this problem and they should. Someone is going to die from this design flaw and it must be addressed soon. I don't know what to do. I have to travel the interstate to get to work.

Hello, I bought a new 2007 Jeep Wrangler and have been having what the industry calls the "death wobble" since the vehicle was new and it is now in for the 4th repair attempt and dealership is telling me that there is nothing they can do to fix it and that they can't replicate the problem this time, although they have now repaired it 3 times now over the last 2 years and were able to replicate the problem each of the other times. Now my new vehicle warranty is within 200 miles of expiring now and I have a broken car that is in no way safe to drive. I will be driving to the mountains to ski this weekend in a snow storm so it should be scary as this is my only car. A simple search for my model year Jeep online and death wobble will return an unlimited amount of information. Obviously I am not the only consumer with this complaint. Can you please advise whom I should contact to address this matter? I don't want to die or kill anyone. The "death wobble" occurs when I encounter a bump in the road at speeds over ~40mph and must be slowed to a near stop to make it quit. I can't seem to get anyone at Chrysler to help me and the dealers can't fix it, what do I do?.
