Intermittently all 3 warning lights will light. My gut feeling tells me it's a bad ABS sensor. I've watched some videos on replacing the sensor and read that most of the time it's the front sensor. Unless I bring it to the dealer, to determine which sensor, it's a crap shoot. I just know if I bring it to my dealer to do the repair it's going to be an ABS module this week, followed by 2 ABS sensors and rings next week. There isn't a lot of love going on with me and my dealer right now. Has anyone replaced an ABS sensor?
