Three problems related to battery cable have been reported for the 2009 Jeep Wrangler. The most recently reported issues are listed below.
After driving in the rain with no leaks evident the next day the car had the wipers running even when the switch was in "off". The headlights are on even though they are switched "off" and the instrument gauges are all non functional as well as the odometer and dome light. Removing battery cable fixes the issue one time then it goes back to not working.
Dash cluster flickers, Jeep shuts off while driving, sometimes starts threw out stall on its own. Won't start all the time. Have an issue we're my battery cables are massively melted causing smoke.
Was driving with low speed when I heard the car alarm and heavy smoke started to show from under the hood. I had no full coverage on the truck so I had to take chance to open the hood and remove the battery cable before the whole car goes on fire. Was lucky this is didn't happen while I am driving on the freeway. The technition said that the fuse box was caught on fire.
