2016 BUICK ENCLAVE Fuelpropulsion System Problems

MY CAR WAS REPAIRED BY A DEALERSHIP IN TEXAS. FIRST THEY SAID IT WAS A FUEL INJECTOR. THEY REPLACED THAT. THEN THEY SAID THAT THAT DIDN'T WORK SO THEY SAID I HAD A CRACKED HEAD. THEY REPLACED THAT. I BROUGHT IT HOME TO SHREVEPORT, LA. AND IT HAD GAS FUMES COMING OF OF THE A/C VENTS. THE DEALERSHIP HERE IN BOSSIER CITY THAT THEY PUT IN A BROKEN PART. THEY SUPPOSEDLY FIXED THE PROBLEM. I PICKED THE CAR UP AND IT STILL HAD GAS FUMES. I TOOK IT BACK. THEY SMELLED IT. KEPT IT FOR 2 DAYS. THEY COULDN'T FIND THE PROBLEM SO THE KEPT DRIVING IT AND RUNNING IT UNTIL THEY COULDN'T SMELL IT ANY LONGER. I PICKED IT UP AGAIN AND I STILL SMELL IT. I BROUGHT IT BACK BUT THEY ARE DENYING THAT THEY DO. EVEN LIED TO GM CUSTOMER SERVICE THAT THEY RODE AROUND WITH ME....

BROUGHT THE CAR IN EARLIER THIS YEAR BECAUSE THE CAR WAS STALLING. THEY TOLD ME IT MAY HAVE BEEN A LOSE CABLE, BUT LIKELY WAS NOTHING. IN THE LAST 3 WEEKS THE CAR HAS STALLED 3 TIMES WITH MY KIDS IN THE CAR. I BROUGHT THE CAR IN 3 DAYS AGO AND THEY LOOKED AT IT AND SAID NOTHING WAS WRONG WITH IT. YESTERDAY IT STALLED AGAIN AND MY WIFE CAME VERY CLOSE TO GETTING REAR-ENDED WITH THE KIDS IN THE CAR. THIS IS A CAR THAT IS 1 YEAR OLD WITH 5.500 MILES ON IT. THIS SHOULD NOT BE HAPPENING AND THE CAR COMPANY IS NOT HELPING ME WITH THIS. HELP!
