I have an 08 Limited and just recently the hazards will turn on randomly running or parked at home. I have tried unplugging the switch on the dash and that didn't work. Replaced the turn signal lever not by choice also did not work. I do have aftermarket HIDs installed 2-3 months ago. I'm out of ideas other than a possible short, bad ground or bad module of some sort. Any help would be appreciated. I did read somewhere else that this has happened before to somebody. The thread was dead with no solution.

On my fathers last super duty (2011) the hazards would randomly turn on on startup from brand new, took it back and they had to replace the main on board computer because it thought the vehicle was in an accident apparently when it obviously wasn't.stupid question Is your horn honking too? It would probably be three consecutive beeps then a break then repeat.

The hazard switch provides a ground path for that circuit. Since it still happens with the switch disconnected there are only two possible causes.
The green/orange wire at pin 48 on connector C2280G in the smart junction box is shorting to ground and completing the circuit or the smart junction box has an intermittent internal short to ground.

Thank you for the help. I'm out of town working. I'll have to work on it this weekend. This gave me a starting point.

Did you ever get this fixed? If so what did you do to get it fixed? I have a 2007 Expedition that recently while on a road trip the Hazard lights kept turning on randomly. I could shut them off by hitting the hazard switch. From what I have been reading in other websites is that the problem in in the Smart Junction box. But I have not found any information as to what exactly in the SJB goes bad and what I can do to fix it.
If anyone has any information on how I can fix this I would greatly appreciate it.
