On & off lights

I have a 2014 Jeep Cherokee Trailhawk.  Since I bought the damn SUV the
dashboard lights goes on and off until the battery is dead.  The whole entire
dashboard in all three sections lights goes on and off.  I have taken it to the
dealer three times on a flatbed and two other times I drove  it back for the
same problem twice and left it there.  They claim to get special workers to
work on the issue.  They call me 5 days later to tell me there is nothing with my
car.  Looked at my car tonight and the same problem is occurring.  I can't take
this anymore so I looking to trade it in.
