Every couple months my dash lights start flashing, my check engine light comes on, my traction control light comes, my TPMS light comes on and along with an annoying beeping sound and my brake light blinks off and on. My information screen flashes back and forth Service Electronic Brake System and then Park Sense Unavailable. Also, sometimes by exhaust break turns on by itself during these episodes. After a couple starts/drives it starts to go away slowly. I've taken it to the dealership and they claim they can't find anything wrong with it. It's now doing it again. It's a 2015 Ram 3500 with the 6.7 Cummins in it with only 51,000 miles. Any help would be appreciated.
