Hazard lights going off for no reason??

I was suspecting the LCM all this time to be honest. I thought that the GT1 was giving fits too. See a few posts above - January 29th - the "issues" diagnosed with GT1. The software "knew" something was wrong, but it was pointing in the wrong direction... Maybe the "hiccup" in the ballast created some weird signal enabling the crash recognition program every time the low beam came on. I don't know?

Thanks for the thread below, really helped me a lot, for the past few days when it's really been cold, after starting my hazard lights were flashing and the dome light stayed on, suspected my battery because it's 5 years old but had a load test a few months ago that indicated it was good so I thought it would be fine until spring, but the thread below tells me to go get a new battery. Really appreciate all of the help on this post.

Carbob, actually check your ballasts.
Unplug one by one and see if it gives you the fits. The "crash recognignition program" minus deployed airbags was what I had when one of the ballasts started to go, although the lights were working fine. Haunted me for a few months.

+1 for the ballast! This is weird problem! I was chasing this issue for months back in 2011. At one point, I reviewed everything that was done to the car for the past year and sure enough, I converted to Xenons using aftermarket lights and set of used BMW (Hella) ballasts. I could not see even remote relationship here, but after swapping one of the ballasts with cheap Chinese knock-off the problem disappear! I even borrowed oscilloscope and briefly tested to see if ballast introduces some kind interference into the car’s electrical system, but did not found anything suspicious during the test.
P.S. The “cheap Chinese knock-off” still working with no issues for four years / over 60k miles! It is my daily driver.

I had a similar experience, although i happen to know EXACTLY what happened to mine, it started at starbucks, my wife had her tea, i had my black coffee, we jockeyed for cupholder space (which does not completely fit two venti cups!!) my coffee spilled a small amount , (10-12 drops) onto the hazzard light switch, and then from out of nowhere, click click click click! the hazzards activated. then stopped for a minute or two, then started up again. I suspect that my coffee completed the switch circuit and allowed the lights to blink. then after a day or two, it all went back to normal. I pulled the switch out, and sprayed some contact cleaner in there. its all good now!

I just had this happen to me which is why I searched for anyone else who may have had a similar issue.

I was parked, turned the X5 on and noticed in the window reflection on the building that my hazard lights were on. There was no audible clicking in the car, the dash lights were not blinking like they do when the harzard lights are triggered, the turn signals wouldn't work, and the hazard light button wasn't flashing. I tried to press the hazard button but it didn't work. I turned the x5 back off and then back on again but that didn't work.

I decided that I couldn't do anything where I was at since I didn't have tools so I drove off. Within 100 yards of driving the lights went back to normal. This seemed really odd, but if you guys are saying it's the battery that might explain it. I bought the X5 a little over a year ago and haven't checked the battery ever. The voltage is reading 12.5v as it sits right now, but who knows if it maybe dropped a bit low and freaked out the LCM.

Anyone else have this experience?
