66 reportsSTRONG SULFUR SMELL (ROTTEN EGGS) WHEN ACCELERATING. CAN SMELL WITH ALL WINDOWS UP. EVEN WORSE IF REAR WINDOW IS DOWN. WHAT'S THE POINT OF HAVING A REAR WINDOW IF YOU CAN'T OPEN IT. I ALSO OWN A 2000 4RUNNER AND IT NEVER SMELLS THIS WAY. *NM
ALMOST CONSTANT SULPHER SMELL. DEALER STATES THAT THEY HAVE NO KNOWLEDGE OF PROBLEM, AND NO TSB'S. THEY TELL ME TO KEEP REAR WINDOW CLOSED. WHEN MY WIFE IS A PASSENGER SHE HAS HER EYES BURNING ALL THE TIME. IF YOU NEED TO STEP HARD ON THE GAS THE WHOLE CABIN FILLS AND IS ENOUGH TO MAKE YOU NOXIOUS. TOYOTA NEEDS TO REMEDY THE PRO…

ALMOST CONSTANT SULPHER SMELL. DEALER STATES THAT THEY HAVE NO KNOWLEDGE OF PROBLEM, AND NO TSB'S. THEY TELL ME TO KEEP REAR WINDOW CLOSED. WHEN MY WIFE IS A PASSENGER SHE HAS HER EYES BURNING ALL THE TIME. IF YOU NEED TO STEP HARD ON THE GAS THE WHOLE CABIN FILLS AND IS ENOUGH TO MAKE YOU NOXIOUS. TOYOTA NEEDS TO REMEDY THE PROBLEM ASAP, OR A CLASS ACTION SUIT SHOULD BE FILED. THIS PROBLEM HAS SOURED ME ON TOYOTA PRODUCTS FOR GOOD. LIKE THE VEHICLE BUT HAVE A HARD TIME CINVICING MY WIFE TO GO ANYWHERE IN IT, SHE ALWAYS WANTS TO TAKE HER KIA SORENTO, MORE COMFORT AND NICER AMENITIES. 2004 TOYOTA 4-RUNNER V-6 LTD 4X4 NOT ACCEPTABLE UNLESS YOU LIKE SULPHUR SMELL WHILE DRIVING! *NM

DT: ONTACT STATES THE DRIVER'S LUMBART SECTION OF THE SEAT IS LOOSE. WHEN YDRIVING AND STOPPING Y CAN FEEL THE FRONT SECTION OF THE SEAT MOVING. AND WHEN TURNING LEFT OR RIGHT CAN FEEL THE SEAT MOVING. THIS HAPPENS ALL OF THE TIME. HE HAS TAKEN IT TO THE DEALERSHIP TWICE AND BOTH TIMES THEY SAID IT IS WORKED AS DESIGNED. HE NOTICED THIS ON 6-30-05. THE DEALERSHIP DID COMPARE THE PROBLEM TO A 2005 TOYOTA FORERUNNER AND SAID THE SAME PROBLEM WAS HAPPENING WITH THE 2005 MODELS BUT THEY COULD NOT DO ANYTHING UNTIL TOYOTA COMES OUT WITH A SERVICE BULLETING OR A RECALL. HE HAS TALKED TO TOYOTA AND THEY GAVE HIM A CLAIM NUMBER AND SAID SOMEONE SHOULD GET BACK WITH HIM ON OR AROUND THE 21ST. OF JULY 05.*AK
UPON ACCELERATION THE EXHAUST EMITS A VERY STRONG ROTTEN EGG SMELL INTO THE CABIN OF THE VEHICLE. THIS ESPECIALLY HAPPENS WHEN THE REAR WINDOW IS LOWERED.
THE DRIVER'S SEAT MOVES (OR ROCKS) WHILE DRIVING. THE LOCAL DEALER ASSURES ME THAT THE DEFECT IS NOT A SAFETY ISSUE, YET I DON'T FEEL COMFORTABLE DRIVING THE CAR. THIS IS AN ONGOING PROBLEM.
INVOLVED IN ACCIDENT,AIR BAGS DID NOT DEPLOY,SEAT BELTS DID NOT HOLD RESULTING IN HITTING STEARING WHEEL AND FRACTURING MY STEARNUM. COLLISION REPAIR CENTER REPLACED COMPUTER THAT CONTROLS AIR BAG AND SEAT BELTS.
