2011 MITSUBISHI LANCER Structure Problems

RENTED FROM HOTWIRE AT SAN JUAN AIRPORT. CAR RENTAL WAS HERTZ. WHILE REVERSING FROM PARKING SPOT AT HERTZ LOT, ROACHES CAME OUT OF DASHBOARD. I STOPPED AT THE OFFICE TO CHANGE CAR. AGENTS WERE NOT CONCERNED. I ASKED FOR ANOTHER CAR WITHOUT THE BUGS AND IT TOOK SOME TIME TO GET ANOTHER CAR. I INSPECTED IT AND DIDN'T FIND ANY. I DROVE OFF. THE NEXT MORNING I DROVE TO PONCE AND BACK THAT NIGHT. DROVE UP & DOWN A STEEP MOUNTAIN SIDE. WHEN I PARKED THAT NIGHT ROACHES CAME OUT OF THAT CAR TOO. CALLED SEVERAL NUMBERS, WAS FREAKED OUT, AND NO ONE SEEMED CONCERNED. MY DAD SPRAYED THE CAR THAT NIGHT, CLEANED IT UP AND THE NEXT MORNING WE DROVE BACK TO HERTZ TO GET A NEW CAR. MY CONCERN WAS THAT IF THOSE BUGS WOULD HAVE COME OUT WHILE I DROVE THE MOUNTAINSIDE, I PROBABLY WOULD HAVE KILLED...
