Sorry to hear about your stability issue. It is something that really needs diagnosis sooner than later. You do not want loss of control at any speed, but especially at higher speeds. I note several others making note of problems with dealer service departments. Not sure where everyone is located, but you really need to do a search and visit of multiple dealerships to find a good service department. Most areas have multiple dealers that are not that far away. I had the same problem. I wouldn't let the place I bought my TH from touch my vehicle. It was just the opposite with the Jeep dealer that is only 12 miles from home here in NH. The guys there are very attentive and patient in listening to a problem and then making a sincere effort the correct whatever it is, and I didn't buy my vehicle there. As frustrating as it is, take some time to seek out a Jeep dealer that has trained staff, a very motivated service manager and a parts department that goes the extra mile to find whatever they need. Take full advantage of your factory warranty, even if it means travelling a few extra miles to get the problem corrected. You might want to contact Jeep Customer Care to get a referral to a properly run service department. Our "specialty vehicles" should be getting "specialty treatment". Best of luck Wetboots.
