VRS Electrical gremlins?

So, my VRS is now just outside the extended warranty period and as is the rule, there's a few things started to happen!

The touchscreen regularly is unresponsive on startup, the radio stations seem to decide where they want to be stored, sometimes selecting a different station will just replace the one you want with the one you are listening to on the saved slot.

Steering wheel controls only go backwards with radio control, if you press the forward arrow it just stays on the current station, back arrow goes backward...

Now the dipped beam light is occasionally throwing up an error, seems like a loose connection as works fine most of the time, other times it flashes and other times not on at all (or is that just the way these bulbs fail?)

Are these likely to be related issues or just coincidence?

These issues pale in comparison to my wife reversing it into a roughcast wall!
