I have a 2011 Sahara and my clock loses about 7 minutes a month. Took it to the dealer and they said Jeep has a STAR Case S1108000113 open which states that "No current repairs are available to resolve this issue currently". "Currently there is new updated module changes being developed and tested for in service vehicles". "New clock modules are not backwards compatible". Guess we just have to wait to hear from Jeep.
