While driving my 2009 Wrangler Sahara my flashers will cycle on and off at times then stop. I have noticed that the door locks cycle when the flashers are doing their thing. Today the brake and traction control lights came on. I have had a no start issue a couple of times where the lights all lit up and got out and unhooked the battery cable and reinstalled it and the jeep started fine. I have checked the battery and load tested it, seemed fine..... any ideas?

 

I would look for a loose ground.

 

Any particular ground?

 

That I can't help with, new to Jeeps. But I have had similar issues with other vehicles in the past and it was a loose ground. All kinds of crazy stuff was happening. Good luck.

 

Anyone have anything similar?

 

Had a couple of dodge products that behaved like that because of a dying battery, the inconsistent voltages play havoc with the computer

 

Actually, when I installed my dead pedal I undid the 2 ground studs by the drivers feet and when the ground lug was loose the heater fan came on then when it made contact again it stopped. Ignition was off but battery connected. So I am with the comment from TheKmanB post #2

 

I replaced the battery and the issue went away for about 5 months. The only thing I noticed different was that I used the key fob to lock the door. The issue started again right after that the following time I drive the jeep. I was thinking that the door locks are part of the issue and the hazard lights flashing is the module that communicates with the key fobs cycling? Heck, Im guessing at this point.
