2012 Grand Cherokee Unidentifiable Problem

Hey All.

I was driving to work one morning and my electrical system went haywire.
Started with the battery light, then my seatbelt light started flashing, followed by service 4wd, airbag lights etc ect . My windscreen wipers went on at the fastest speed and then my speedo cut in and out.
While all this was going on my entertainment system cut out and so did my heated seats. Oh and my turn signals stopped working too...

I took it to my service centre and they couldn't find anything wrong with it (surprise). So I got the car back and has happened maybe 15 times in 6 months.
I took a video of it happening but can't post it...
Anyone ever come across something like this or have any ideas what it could be?
Appreciate the help and the service centre is not interested.
Dave

Check your battery grounding wires, there was a recall for loose connections once
