My 991 GT3 experience multiple errors / failures on Sunday. The errors I am seeing are:
1) Loss of Steering Support - Increased Effort
2) Transmission fault Possible no R gear. Drive on Possible.
3) Fault of headlamps control system
4) PSM System Fault
5) Breakdown of rear steering, take care when driving
6) Fault Parking Brake
7) Fault engine control - Possible to drive on

My car is at the dealership now being diagnosed. I was told this could take several days.

Has anyone else had an issue like this?

You are the first with this kind of incident. Out of curiosity, were you low on fuel?

Did you turn-off and restart your car to see if it occurred again?? Some times it could be a Computer glitch

Is it a new car? Are you running the lightweight battery?

I had an issue after 500km's on my RS where the car just went into limp mode in the middle of the highway, was shutting down and worked normally only at idle, whenever I tried to move forward it was cutting power and all electronics started blinking and lights going off..

Anyway managed to limp to the nearest dealership, luckily 20kms away and the reason was that my dealership connected the lightweight battery wrongly... the lightweight battery has two ports for one of the wires (not the negative neither the positive) and the cable was inserted into the wrong one, sorry not very familiar with the technical part, but anyway solved my problem.

Was the battery on a tender prior?

Since it is pretty much impossible that all that stuff failed at once, it will probably be something easily rectified. Keep us posted.

I'm guessing a bad battery. I have seen warnings lights and electrical items not working properly when batteries go bad.

Chewed up wires?

tonycool

Nope, not low on fuel.

tonycool

Yes, I restarted the car multiple times.

tonycool

The car is a 2014 with ~6,000 miles. I am running a standard battery.

tonycool

Yes, I agree it isn't likely all these things failed. I'm hoping it is just something stupid & simple.

tonycool

You could be right, however, it would be kind of a weird failure if the car has plenty of battery to start the car but it causes these other issues.

tonycool

I sure hope not, but who knows. I will keep everyone posted. I was told by the dealership it could take several days to diagnose given the PWIS hasn't been very helpful so far.

If you can start the car. What's the voltage meter measure when the car is running?
