THE MILEAGE AND SPEED ARE APPROXIMATE. I WAS BACKING OUT OF MY ICE AND SNOW COVERED DRIVEWAY IN FEBRUARY 2015. THERE IS A SMALL DIP WHERE MY DRIVEWAY MEETS THE STREET SO I ACCELERATED SO AS NOT TO GET MY TIRES STUCK IN THE ICY DIP. AS I WAS BACKING MY CAR INTO THE STREET, AND MY CAR WAS IN THE LANE OF TRAFFIC THE CAR SHUT OFF. I WAS UNABLE TO RESTART THE CAR. MY NEIGHBOR, AND ANOTHER GENTLEMAN WHO STOPPED TO HELP, PUSHED MY CAR BACK INTO MY DRIVEWAY. I ATTEMPTED TO START THE CAR SEVERAL TIMES AFTER THE INCIDENT. THE CAR NEVER AGAIN STARTED. I BORROWED A VEHICLE UNTIL I HAD ENOUGH MONEY TO HAVE THE CAR TOWED TO A MECHANIC FOR REPAIRS. A MECHANIC LOOKED AT MY VEHICLE AND TOLD ME ON MAY 11, 2015 THAT THE CAR NEEDS A NEW ENGINE, THE PRICE OF WHICH IS $4,823.00. THE MECHANIC FURTHER TOLD ME THAT THE AFTERMARKET/REMANUFACTURED ENGINES COMPANY THEY DEAL WITH DOES NOT HAVE AN ENGINE FOR THIS MAKE AND MODEL CAR BECAUSE THIS ENGINE HAS SO MANY PROBLEMS THAT THE COMPANY WILL NOT TOUCH IT. I BELIEVE THAT THE OEM ENGINE HAS SERIOUS DEFECTS THAT HAVE BEEN OVERLOOKED DUE TO THE LACK OF REPORTING AND LACK OF SERIOUS INJURY ASSOCIATED WITH THE DEFECT/FAILURE. MY CAR HAS SHUT OFF ON ME ON THREE DIFFERENT DAYS WITHIN AN APPROXIMATE SIX MONTH PERIOD. I HAD A MECHANIC LOOK AT THE CAR TO FIGURE OUT WHY IT WAS SHUTTING OFF ON ME IN TRAFFIC AND THERE WAS NO INDICATOR OF ANY ISSUE. MY CHECK ENGINE LIGHT NEVER CAME ON, EVEN AFTER THE RECENT ENGINE FAILURE. PLEASE INVESTIGATE THIS ENGINE. *TR
