Rear Suspension Springs problems of the 2011 Jeep Grand Cherokee

My 2011 Jeep Grand Cherokee has repeatedly incurred severe problems with the tipm (module) which controls the car's quad air suspension system. This car has been serviced by skinner and damulis, richfield springs, n. Y. (at least) six times for the same problem, at great expense - with no apparent resolution but to incur repairs costs in excess of $10,000. The 8/6/17 incident too, dealt with the defective air suspension system which, this time, caused the rear wheel to fall off while the car was being driven. My wife and I incurred injuries, however, the dealer told me that this issue was not related. Just two days ago, the car's suspension system lighted up on the dashboard. Pictures were taken, I called the auto dealer, however, I have yet to hear from them. In reviewing filed complaints coupled with a class-action lawsuit, this is all to familiar, however, Chrysler and their dealers' refuse to acknowledge and fix this problem with the full support from Chrysler.
