It seems about once a week all 4 of these lights come on. It will happen as you are going 60 down the freeway, starting from a stop at a stop light, or applying the brakes. If you turn the vehicle off and start it again, they wont come back on. Any thoughts? It's really annoying. As far as I can tell nothing actually happens when they come on. It's a 2006 4x4 v8 if that helps.
