So what does it mean when you are driving along at around 30 MPH and all of the sudden EVERY light on your dashboard comes on, the dials for MPH and RPM crash but your engine is still running. This happened to me five times on my way into work today. It has stopped but I am obviosly worried about it. Has anyone come across a similar issue. This is happening on my 2006 Grand Cherokee 3.7 with 101k miles on it
