Two problems related to transfer case have been reported for the 2011 Jeep Wrangler. The most recently reported issues are listed below.
Shifting the 4-wheel drive transfer case (tc) from 2hi to 4hi or 4low (or in reverse order) can cause the transfer case shifting cable (tcsc) (mopar part 52060462ag) to fail and become disconnected from either the tc or the shift lever in the cab (or both). The part?s plastic components are inherently too weak to withstand normal use. Safety risks which can arise upon component failure, if the vehicle owner and their family (children) are at a location and/or terrain where the vehicle is designed/marketed for travel (whether by recreation or necessity), and the location/terrain (I) subject to inclement weather (e. G. Snow, ice, flooding, extreme heat); or (ii) on an extreme incline which is unsafe to negotiate without 4wd; or (iii) any circumstance which requires 4wd to navigate to a safe location; or (iv) the tcsc fails when the tc becomes stuck in the neutral position while shifting, and is unable to escape impending harm (flash flood) . . . There is obvious risk to life/safety. The owner has a right to rely on the components and reasonable safety performance for which the product is designed/marketed. Jeep is aware of the issue, and the manual fails to cite this as a possible catastrophic event, leaving the unsuspecting owner at a loss in an emergency situation. It is not reasonable for this component to fail within a few thousand miles as reported by Jeep owners. . Read more...
While traveling in traffic lane, attempted to shift transfer case (not transmission!) to high range from low range. This is a 4-wheel drive vehicle with a manual x-fer case. (manufacturer ok's shift while in motion) vehicle ended up coasting in neutral, and upon later exam it was found that the flimsy plastic shift cable retaining clip on the cable which connects the shift lever in the cabin to the shift arm on the x-fer case had shattered. This in turn allowed the shift cable to fall off the lever, disabling the vehicle in an active traffic lane.
