2012 ford explorer exterior lights and interior lights won't turn off

I bought a 2012 Ford Explorer and when I park the
car and lock it the exterior lights and the interior
lights stay on but the only time the lights will turn
off is when I hit the dashboard with my fist and
then the exterior lights will turn off but the interior
lights still stay on when I say interior lights I don't
mean the dome lights I mean the panel lights I
took the car 2 Ford they held it a week and said
nothing was wrong I can't tell them that the only
way I can turn the lights off is if I hit the dash
because I'm afraid that I might lose my extended
warranty any help would be appreciated
