One problem related to sway bar has been reported for the 2011 Jeep Wrangler. The most recently reported issues are listed below.
Took 2011 Jeep jk to car wash. Afterwards "sway" bar light started to flash. Shut car off, restarted and ran through disconnect procedures- put trans/diff in neutral and hit disconnect button- light went off. While driving Jeep to work next morning, all the lights on the dash board flashed and car shut off. Jeep would not start. Tipm was fried with disconnect motor. Water had got into connection by sway bar disconnect motor. They are not water tight. Have read other stories of happening during rain storms.
