Random electrical issues
 

My 2017 Rubicon has now been in the shop for a total of seven weeks straight, no end in sight, contacted FCA and a case manager was assigned.
The problems are sway bar light flashes on and off, engine light, oil pressure light, seat belt chimes constantly and it stops recognizing the key fob. Supposedly they have changed out the wiring harness, TIPM and PCM, but I don't think they have actually done anything to it, they still haven't touched the problem.
Just wondering if anybody else has ever had a similar issue, if so what might the solution be.
