Open the full vehicle complaint log (all categories)APPROXIMATELY 5 MILES AFTER RECEIVING THE VEHICLE THE ROD BEARINGS AND CRANK SUFFERED COMPLETE FAILURE. I WAS IN MOTION AROUND 60MPH ON A RURAL HIGHWAY WHEN THE ENGINE SUDDENLY LOST POWER. AFTER AVOIDING AN ACCIDENT I SAFELY PULLED OVER AND SHUT THE CAR OFF. THE ENGINE WOULD NOT START. THE SEIZED ENGINE WAS DIAGNOSED BASED ON AN IMMOBILE CRANK AND OIL CONTAMINATION BY THE MANUFACTURER'S DEALERSHIP. I THEN HAD THE OIL PAN COMPLETELY REMOVED AT AN INDEPENDENT SHOP TO CONFIRM THE MANUFACTURER'S DIAGNOSIS, IT WAS CONFIRMED. ALL PREVIOUS OIL CHANGES WERE DONE AT THE MANUFACTURER'S DEALERSHIP BY THEIR TECHNICIANS MORE OFTEN THAN THE MANUFACTURER RECOMMENDS. THE MOST ALARMING PART IS THE VEHICLE HAS LESS THAN 23000 MILES. I'VE REACHED OUT TO THE MANUFACTURER, MENTIONING THIS VERY WELL-KNOWN ISSUE AND THE FACT THAT THERE ARE CLASS- ACTION LAWSUITS PENDING ABOUT THIS VERY ISSUE, ONLY FOR THEM TO TELL ME THEY ARE NOT LIABLE. THEIR PRODUCT FAILED BEFORE 23000 MILES, THEY KNOW ABOUT THE ISSUE HOWEVER THEY ARE DOING NOTHING FOR ME. THE PUBLIC SHOULD KNOW ABOUT THIS FAILURE BECAUSE IT CAN CAUSE A SUDDEN LOSS OF POWER AT ANY MOMENT.
DRIVING IN A PARKING LOT, SHIFTED FROM 1ST GEAR TO SECOND GEAR AND AT 4000 RPMS, THE CAR STOPPED. IT WOULD NOT RESTART. TOWED CARD TO DEALER AND IT NEEDED AN ENGINE REPLACEMENT WHICH WAS COVERED UNDER MY WARRANTY.
