I have a 2011 Grand Caravan R/T and had something pretty scary happened to me yesterday on return from my vacation. I was in the midst of my 2000km(1300m) trip when all my instrument panel lights blinked on, including my radio, my tach and speedometer went down to zero and a second or two later returned to normal. All the while my van was driving fine as usual. It happened once before maybe a week earlier and thought it was just my mind playing tricks on me. Yesterday It happened to me once earlier in the day. Then yesterday late afternoon it started happening over and over again. Keep in mind other than this the van was running fine. I pulled up to the next gas station, gassed up and checked to see if I possibly had a loose fuse, found nothing. I am up @ the New Brunswick/Quebec border, not a lot around and the van is actually running fine so I continue on my way. The flashing continues after the gas station stop, on and off for another hour, driving us all nuts while practically crapping in our pants. After about 45 mins. to an hour it stops and goes back to normal for the next 3-400 kms. Didn't happen again yesterday as I stopped for the night. Finished the last 800 kms. today with no events. Needless to say I have already booked with my dealer to check it out tomorrow.
