My 2015 6.2L 4x4 is experiencing either a bad computer module or bad wiring with under 50k miles?
Last week I was driving to work and all the warning lights went off and none of the gauges/speedometer worked except the fuel gauge.
When I left work it did the same thing. I pulled over on the exit ramp and shut it off and then it wouldn't start up for about 10 minutes.
I drove it straight to my mechanic and after he looked at it he said I need to take it to Ford because of all the codes.
they tried tracing all the ground wires but not the positive wires.
It wouldn't start for a couple days and then it started right up.
I drove it home and parked it until I needed to move my RV back to storage - it started right up and all the idiot lights went off again.
I just kept it running the whole time I got RV ready hooked & unhooked at storage.
Then I noticed none of the lights came on and everything seemed fine.
I dropped it off at a Ford Dealer that works on all the city trucks but they said it will be 2 weeks before they can even look at it.
In the meantime I'm having to rent a vehicle to get back-n-forth to work.
My mechanic thinks it's a computer module and Ford said it sounds like a wiring issue?
Any ideas what this could be?

 

Stab in the dark here....But I've read of issues with wiring harness near the parking brake pedal.....it comes loose and creates a whole whack of issues such as what you have.....Can't recall what years this affected...but worth a look.

 

thanks for taking time to reply srxfun, I had read about that issue a couple months ago while trying to figure out "SERVICE ADVANCE TRACK" warning.
Hopefully the Ford Truck Technicians will look at that first?
