“WHEN PULLING THE FUEL DOOR RELEASE LEVER THE DOOR FAILS TO OPEN. HAPPENED ONCE A LITTLE OVER A YEAR AGO. THEN ABOUT 2 MONTHS AGO IT WAS EVERY OTHER TIME I NEEDED TO FILL UP. NOW IT'S EVERY SINGLE TIME. I FUEL UP EVERY 4-5 DAYS AND IT'S STARTING TO BECOME A HASSLE. I PICK UP MY WIFE FROM WORK SO THAT'S WHEN I DECIDE TO FUEL UP, SHE REACHES OVER AND PULLS THE LEVER MULTIPLE TIMES WHILE I SLIP MY ID/DEBIT CARD THROUGH THE GAP TO POP OPEN THE FUEL DOOR OPEN. SOMETIMES THE DOOR POPS OPEN A BIT WHERE I CAN PULL IT OPEN WITH MY NAILS. IT NEVER FULLY OPENS HOW IT USED TO BEFORE LIKE WHEN I BOUGHT IT. WHEN I'M BY MYSELF SELF I DRIVE OVER BUMPS WHILE PULLING THE RELEASE LEVER REALLY QUICKLY, NOT TO MENTION HOW DANGEROUS IT IS BECAUSE I HAVE TO REACH DOWN WHILE DRIVING. SOMETIMES IT OPENS RIGHT AWAY WHEN I HIT SOME BUMPS SOMETIMES IT TAKES A WHILE. JUST THINKING ABOUT GETTING STRANDED BECAUSE I CAN'T GET IT TO OPEN REALLY WORRIES ME. LOVE MY CAR, HAD IT FOR ALMOST 3 YEARS AND THIS IS THE ONLY THING SO FAR THAT'S MALFUNCTIONING. *TR”
Fuel/propulsion system
5 reports
“VEHICLE IS BURNING OIL, OIL CAME OUT THROUGH WHERE THE DIP-STICK IS PLACED. FOUND OIL ON THE EXHAUST TIPS. MASS AIR FLOW SENSOR IS MALFUNCTIONING. REQUIRES NEW COILS AND SPARK PLUGS EVEN THOUGH I HAVE ALREADY REPLACED THEM. REQUIRED A NEW BATTERY, HOWEVER, REPLACING THE BATTERY DID NOT KEEP THE VEHICLE FROM TURNING OFF BY ITSELF. O2 SENSOR, BANK 1 SENSOR 2, IS ALSO MALFUNCTIONING.”
Exterior lighting

“DRIVERS SIDE HEADLIGHT IS RANDOMLY DISABLED. LIKE THE MAJORITY OF OTHERS HAVING THIS ISSUE, MY CAR HAS BEEN IN A COLDER CLIMATE (MINNESOTA) WHEN THIS STARTED OCCURRING. THERE IS NO WAY OF TURNING IT BACK ON. *TR”
