Just picked up a 2011 JK. I happen to be in the hospital at the moment and my wife sent a video of the dash as she was driving home. Speedo bouncing up and down, abs, brake, and sway bar lights going off in the dash. Has anyone come across this before?

Beings it's a 10 year old Jeep i'd start out cleaning and tightening all the cables on the battery and other grounds through out the Jeep.

That was my thought also what @BLACKJKU said Most likely a grounding issue

I agree that cleaning connections and ground wires is definitely a good place to start.

Have your wheel speed sensors checked, they also run the overdrive, ABS, speedo and probably more.
