We have a 2014 Cherokee that we purchased new specifically to tow. It has wobbled several times in the last nearly 2 years including 3 times in the last 3 weeks. It can create a very dangerous issue as the only way to stop it is to come to a complete stop. I called the number provided above today (February 29, 2016) and the representative had never heard of the issue and had no idea about the "fix" that has been mentioned in this thread.
Please continue to press them for us. We really appreciate the work that Mr. Johnston has done so far. We are leaving in May for a 3 month trip covering over 10,000 miles and need to get this issue completed before then. We have been FMCA members for several years and know how valuable that membership is.
