Open the full vehicle complaint log (all categories)I TOOK THE VEHICLE IN FOR A 55,000 MILE SERVICE. TOYOTA DEALERSHIP INFORMS ME THAT THE VEHICLE IS LEAKING OIL FROM BOTH SIDE OF THE CAM TOWER. THEIR ESTIMATE TO FIX IS OVER $4000. PARTS ARE $170 AND 25 TO 30 HOURS OF LABOR TO REMOVE THE ENTIRE ENGINE. THE LEAKING OIL IS A SAFETY CONCERN, AND IT IS DUE TO A FAILED SEALANT THAT APPEARS TO HAVE COME THAT WAY FROM THE FACTORY FROM MANY OTHER CASES I HAVE READ. THE COST OF REPAIR MAKES IT UNREALISTIC FOR MOST OWNERS WHO WILL MORE THAN LIKELY NOT REPAIR IT IN A TIMELY MANNER. THE ISSUE MAY ALSO GO UNNOTICED IF TAKEN TO ANOTHER MECHANIC OTHER THAN A DEALER WHO IS NOT FAMILIAR WITH THE ISSUE.
VEHICLE WAS STARTED AND PUT INTO REVERSE. THE VEHICLE IMMEDIATELY BEGAN TO ACCELERATE. BRAKE WAS STEPPED ON AND DEPRESSED WITH BOTH FEET, BUT THE VEHICLE CONTINUED TO SPIN TIRES TRYING TO ACCELERATE TO A MAXIMUM SPEED. VEHICLE WAS THEN THROWN INTO "DRIVE" AND THE VEHICLE ATTEMPTED TO ACCELERATE TO A MAXIMUM SPEED FORWARD SPINNING ALL FOUR TIRES (WHEN NOT IN FOUR WHEEL DRIVE). THE VEHICLE WAS THEN THROWN INTO PARK AND SHUT DOWN. LATER THAT NIGHT (WHILE THE CAR WAS PARKED AND UNOCCUPIED) THE VEHICLE ATTEMPTED TO START ITSELF. THE HEADLIGHTS AND INTERIOR LIGHTS TURNED ON AND OFF WHILE THE VEHICLE ATTEMPTED TO SPIN THE STARTER. THE VEHICLE DID NOT START AS IT ALSO APPEARED TO DRAIN THE BATTERY. THIS CONTINUED FOR APPROXIMATELY 5-7 MINUTES. ADDITIONALLY, THE INTERIOR EQUIPMENT SUCH AS THE RADIO AND SPEAKERS TURNED ON AND OFF WHILE THIS ELECTRICAL ISSUED WAS GOING ON. EVENTUALLY THE CAR'S BATTERY FAILED AND ALL OF THE ABNORMALITIES STOPPED. I HAVE NOT STARTED THE VEHICLE SINCE, AND IT WILL BE BROUGHT TO THE DEALER.... *TR
