Electrical system
14 reports4 fires
“We arrived at church, and I remained behind finishing my makeup. My husband locked the car with the fob out of habit, and my foot was holding the passenger door open. Forgetting the door had been locked with the fob, I accidentally allowed the passenger door to close. I had no keys. Services began, not a soul in site outside. I began to panic when I could not get the door or any other to open. The alarm would not trigger, and the sunroof was cracked accidentally about an inch. It was July. I could not get anyone to hear me, and could not get any door or window ajar. Eventually I was able to get the attention of an elder, who went and retrieved the keys and got me out. I was soaked in sweat, using an inhaler about every 20 minutes, extremely scary. The other time this happened, my son was sitting in the car but the alarm went off and would not let him out until I came with the fob. He was 15, so he was not young. I had no idea he could not exit the vehicle should he choose. I know there is some emergency release in the hatch somehow but could not locate. Air bags were scheduled to be replaced, had rental scheduled with dealership, drove 45 minutes to leave car…”

“I DROVE THE CAR A MILE TO THE STORE AND A MILE BACK AND WHEN I WAS WALKING AWAY YOU COULD SEE A SPARK AND THEN A MINUTE LATER ANOTHER ONE AND ANOTHER UNTIL THEN THE CAR STARTED SMOKING AND WITHIN 4 MINUTES THE CAR WAS ENGULFED IN FLAMES. MY SECURITY CAMERAS CAUGHT THE WHOLE THING ON TAPE. WE TRIED OUR BEST TO CONTAIN THE FIRE BUT IT TOOK THE FIRE DEPARTMENT TO PUT IT OUT.”
Fuel/propulsion system
4 reports1 crash
“MAJOR FUEL LEAK UNDER ENGINE OF CAR ON A COLD START (COLDER TEMPS ~40 DEGREES FAHRENHEIT OR LESS). FUEL SMELL IMMEDIATELY ON START UP, WITH A STEADY STREAM FUEL DRIPPING UNDER THE CAR...FUEL LINES THE DRIVEWAY WHEN BACKING OUT. DRIPPING APPEARS TO STOP AFTER CAR WARMS UP, SO MULTIPLE FAILED ATTEMPTS TO DIAGNOSE ISSUE. HOWEVER, NOW CAN SEE THAT ALL INJECTORS LEAK AND SPRAY FUEL FROM THE HOUSING...APPEARS TO BE WHERE THE PLASTIC AND METAL MEETS. CAR RUNS FINE THROUGHOUT THIS TIME. AFTER SEARCHING THE INTERNET, IT APPEARS THAT THE FUEL INJECTORS ARE KNOWN TO BE FAULTY AND THE PROBLEM WAS SUBSEQUENTLY CORRECTED AT SOME POINT. THERE IS ENOUGH FUEL POURING OUT TO QUICKLY IGNITE AND BURN UP THE CAR, GARAGE, AND HOME IN A SHORT AMOUNT OF TIME. SHOP QUOTED WELL OVER $2K TO REPLACE THE INJECTORS, AND WAS UNCERTAIN IF IT WOULD FIX THE PROBLEM. ASKED ME TO TOW THE CAR FROM THEIR LOT, FOR FEAR IT WOULD IGNITE. CLEARLY A DANGEROUS ACCIDENT WAITING TO HAPPEN AND IT I AM SHOCKED TO SEE THERE IS INFO ONLINE AND AT NHTSA, BUT NO SAFETY RECALL.”
