I have a 2009 jku w/ 100 000 kms on it and I have recently been experiencing the same problem. I thought it may have been over heating but my temp gauge is at normal operating temps. verified that with a freeze frame w/ obd adapter. I know earlier models had some issues with wcm (wireless control module) but that caused no starts. My light only comes on while driving and hasn't seemed to affect the vehicle operation in any way.
Im getting worried as I have recently been tinkering with my dash wiring (removed my stereo and installed a tablet w/ amp) and im hoping I haven't tripped any electronic warning indicators as I have heard these jeeps have pretty sophisticated electronic monitoring. I am beyond my warranty and refuse to pay a dealership for anything I can fix myself. I probably wont explore it too much more.
On a side note, I have also recently noticed my low tire pressure indicator going on and off while I drive but I usually just ignore it. wondering now if maybe the two may be connected... if you find anything out let me know
As in another thread, I had the same thing happen, so took my Jeep into the dealer. At first they didn't know but then when one of the guys checked on line it was some kind of recall, and they got it fixed.
OlllllllO Another Day in Paradise with my Gecko!
