2004 TOYOTA 4 RUNNER Engine And Engine Coolingexhaust System Problems

STRONG 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 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

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.

LEAKAGE OF SULFUR DIOXIDE (SO2) FUMES FROM EXHAUST INTO CABIN OF VEHICLE, SMELLS LIKE "ROTTEN EGGS." EXPOSURE TO SO2 HAS ADVERSE HEALTH EFFECTS, SOURCE EPA. I SUFFER FROM ASTHMA AND THE SULFUR FUMES CREATE SERIOUS SAFETY AND HEALTH HAZARD.

ROTTEN EGG SMELL WHEN THE GAS PEDAL IS DEPRESSED QUICKLY FROM EITHER A STANDSTILL OR ALREADY MOVING. I'VE TRIED ALL DIFFERENT TYPES OF GAS BUT TO NO AVAIL.*AK
