One problem related to transmission failure has been reported for the 2011 Jeep Compass. The most recently reported issues are listed below.
(among other problems), this 2011 Jeep Compass has transmission difficulties. On multiple occassions the automatic transmission has failed to shift from gear to gear without manual assisstance. It will whicne and strain and just not change, even as the rpm climb sky high, it will not shift without assistance. This failure was first documented on 6/19/11 but there were multiple failure before this date. The system failure has resulted in a reduction of power to such extent that it is difficult to safely merge into a lane of traffic. During such episodes the accelerator could be pressed to the floor and the maximum speed whould nto exceed 20 or 25 miles per hour. This vehicle (which has other problems) is considered to be unsafe. I am presently waiting for a company "investigator" to access these problems.
