The contact owns a 2011 Jeep Wrangler sahara 4X4. The contact stated that the vehicle would independently shift out of gear when driving at any rate of speed. The vehicle was inspected by the dealer who advised that the boot under the gear would become too cold and causing the gears to shift independently. The dealer repaired the vehicle by removing the boot. After repairs, the vehicle began to exhibit an abnormally loud noise from the transmission. The vehicle was inspected by a dealer and they advised that the recent failure was caused by the removal of the boot. The vehicle was not further repaired. The failure mileage was approximately 900.

2011 Jeep Wrangler rubicon unlimited. 6spd transmission pops out of 2nd and 4th gear when weather is cold. 2nd gear "crunches" when going into gear. It's been in for service on the transmission 3 times now in 3500 miles. Problems seem to be getting worse. In cold temperatures, the vehicle is very difficult and dangerous to drive.

I have a 2011 rubicon andt 2nd and 4th pops out all the time. 1st and 3rd lock in great. If I push the clutch in I don't even have to touch the shifter and it will automatically roll out of 2nd and 4th. When the temp is below 15 or 0 outside.

Jeep pops out of 4th gear at times when cold. More so after hitting bumps in the road. Has happened at least 5 times now.

I own a 2011 Jeep Wrangler with a manual transmission. In cold weather and with the vehicle cold, fourth gear continually pops out of gear and now 2nd is starting to do it. I brought it to the dealership, but they could not duplicate the problem. Also, they checked the tsb, but none are listed. I have read Jeep forums and learned that some believe the problem with the 2011S is the boot, either inner or outer or both. When it is cold outside, the boots don't flex well--so it pushes the vehicle out of gear. I have been in the middle of a turn and it happens--huge safety issue.
