VEHICLE WAS IN FOR OIL CHANGE 4 WEEKS PRIOR TO INCIDENT. ENGINE BEGAN TO MAKE A LOUD BANGING NOISE. STOPPED AT A JIFFYLUBE, AND FOUND OIL VERY LOW. FILLED WITH OIL AND WAS TOLD THAT IT SOUNDS LIKE I THREW A ROD, BUT IT SHOULD BE OKAY TO GET ME WHERE I WAS GOING (ABOUT 5 MILES UP THE ROAD). APPROXIMATELY 2 MILES LATER, WHITE SMOKE BEGAN COMING OUT THE BACK OF THE VEHICLE, AND THE BANGING STOPPED. THE SMOKE BECAME VERY BAD, AND I WAS ABOUT TO PULL INTO A GAS STATION WHEN SOMEONE PULLING OUT YELLED TO ME THAT IT WAS ON FIRE (IN THE ENGINE COMPARTMENT). I GOT ME AND MY 2 SMALL BOYS OUT, AND CAME HOME THAT SAME NIGHT TO THE HEAD GASKET RECALL NOTICE IN THE MAIL. I IMMEDIATELY CALLED TOYOTA, WHO SENT SOMEONE OUT TO INVESTIGATE, BUT THEY SAID THAT THE INVESTIGATION CONCLUDED THAT THE CAUSE WAS NOT KNOWN, AND IT WAS NOT THEIR RESPONSIBILITY. I WAS READING MORE HORROR STORIES ABOUT THIS ON YOUR SITE. WHAT CAN BE DONE? MY VEHICLE WAS PAID FOR AND MY INSURANCE DID NOT COVER FIRE. WHY DID IT TAKE THEM SO LONG TO GET THE HEAD GASKET RECALL NOTICE TO ME? IT APPEARS THAT THIS WAS AN ISSUE FOR SEVERAL YEARS. I BASICALLY DROPPED THE ISSUE FOR SEVERAL YEARS FIGURING I WAS FIGHTING A LOSING BATTLE, UNTIL I DISCOVERED THIS SITE. THANKS.*AK

MY TOYOTA 4-RUNNER BLEW A HEAD GASKET 10 MONTHS AFTER PURCHASE. I CONTACTED BOTH RENO TOYOTA AND CARSON TOYOTA. NIETHER DEALER WERE HELPFULL IN RECALL INFORMATION. AFTER REPLACING THE MOTOR, MY MECHANIC ASSURED ME THAT IT WAS A COMMON ACCURANCE IN THE 4-RUNNER TO HAVE FAULTY HEAD GASKETS. I THEN CONTACTED CARSON TOYOTA AND THEY TOLD ME THAT THEY WOULD FIX THE PROBLEM BUT NOT PAY FOR ANYONE ELSE TO DO SO. BY THE TIME THEY CONTACTED ME THE WORK WAS COMPLETE AND A BILL OF OVER $6500 WAS INCURED. I DONT BELIEVE THEY WOULD HAVE OFFERED TO FIX THE PROBLEM IF THEY DIDN'T KNOW IT EXISTED. I CAN'T SEEM TO GET ANY RECALL INFORMATION FROM TOYOTA, AND I WAS HOPING YOU COULD HELP. THANKYOU , RON COLLINS. *AK
WATER IS BEING SUCKED INTO ENGINE, AND HEAD GASKET PROBLEM. THERE IS A DEFECT IN HEAD ENGINE GASKET. TOYOTA IS AWARE OF PROBLEM. *AK
