2003 Toyota 4 Runner

2003 4RUNNER SE V8: DURING ACCLERATION, I HAVE EXHAUST GASES ENTERING THE PASSENGER COMPARTMENT. TOYOTA CONFIRMED THAT THE V8 IS MOSTLY AFFECTED DUE TO THE LARGER DISPLACEMENT ENGINE. ALSO, PER TOYOTA, THE EXHASUT GASES ARE ENTERING FROM A VENT LOCATED ON THE LEFT REAR OF THE VEHICLE. HOWEVER, TOYOTA INSISTS THAT THIS PROBLEM IS DUE TO THE FUEL. I HAVE TAKEN THIS TO ARBITRATION AND WAS DENIED, EVEN THOUGHT TOYOTA FREELY ADMITS TO THE PROBLEM. BASED ON THE OUTCOME, I HAVE ASKED TOYOTA TO STATE THAT THIS IS A SAFE CONDITION AND WAS ALSO DENIED.

WE HAVE OWNED THE '03 4-RUNNER FOR A COUPLE OF MONTHS AND WE HAVE CONSISTENTLY EXPERIENCED A "ROTTEN EGG, SULFUR / AMMONIA TYPE SMELL THAT HAS YET TO SUBSIDE. WE HAVE TRIED USING EXXON, SUNOCO, AND SHELL 89-93 OCTANE AND THE SMELL STILL PERSISTS. IT IS MORE APPARENT WITH THE REAR WINDOW DOWN, BUT DEFINITELY EXISTS WITH ALL WINDOWS UP. THE SMELL IS CHOKING AND CAUSES GREAT DIFFICULTY TO BREATH. IT SEEMS TO BE CAUSED BY MODERATE ACCELERATION. *PH

WE PURCHASED A 2003 TOYOTA 4RUNNER IN MARCH 2003 OF THIS YEAR FROM POWER TOYOTA CERRITOS. FROM THE FIRST WEEK OF DRIVING TO THE CURRENT DATE, THE EXHAUST EMITS A SULFUR ODOR DURING REGULAR AS WELL AS HARD ACCELERATION. THE ODOR IS ESPECIALLY NOTICEABLE WHEN THE REAR WINDOW IS ROLLED DOWN. CURRENTLY WE HAVE OVER 5,000 MILES ON THE VEHICLE AND HAVE CONFRONTED THE TUSTIN TOYOTA DEALERSHIP WHERE WE HAVE HAD IT SERVICED A COUPLE OF TIMES. WE RECEIVE THE SAME RESPONSE EVERYTIME THAT IT IS NORMAL AND DUE TO THE GASOLINE OR THE CATALYTIC CONVERTER NEEDS TO "BURN IN". SINCE CA HAS THE STRICTEST EMISSION LAWS, I'M SURE THE GAS IS THE LEAST OF OUR WORRIES. I READ ON ALLDATA.COM THAT THERE IS A TSB (EG003-03) FOR A SULFUR SMELL, HOWEVER THERE IS NO SPECIFIC DATA ON IT. I HAVE READ HUNDREDS OF COMPLAINTS ON THIS ISSUE ON SITES LIKE EDMUNDS.COM, HTTP://WWW.4X4REVIEW.COM/DISCUSSIONS/TOYOTA/DEFAULT. ASP, AND OTHER COUNTLESS SITES. DEALERSHIPS SEEM TO DENY THE PROBLEM EXIST. ALTHOUGH IT CURRENTLY IS NOT A SAFETY RISK, WHY WAIT TO FIND OUT? MY WIFE AND I ENJOY EVERYTHING ELSE ABOUT THE VEHICLE, BUT THIS NUISANCE IS BEGINNING TO OVERSHADOW OUR VIEW OF TOYOTA'S QUALITY. *JB

I HAVE A 2003 TOYOTA 4RUNNER AND HAVE HAD A STRONG SULFUR SMELL INSIDE THE VEHICLE WHEN ACCELERATING TO HIGHER SPEEDS. THIS SMELL IS EXTREMELY IRRITATING AND THIS PROBLEM APPEARS TO BE HAPPENING MORE FREQUENTLY. TOYOTA REPS SAY ITS THE GAS, BUT MY 2001 TOYOTA SIENNA HAS NEVER DONE THIS, EVEN THOUGH THE SAME GAS IS PURCHASED FROM THE SAME SOURCE. JUDGING BY ALL THE SIMILAR COMPLAINTS I'VE READ TOYOTA HAS A PROBLEM THAT IS EITHER BEING MIS-IDENTIFIED, OR IGNORED. ONE TOYOTA SERVICE MAN INFORMED ME THAT THE 2003 4RUNNER HAS A NEW CATALYTIC CONVERTER. SEEMS LOGICAL TO LOOK INTO THAT AREA FIRST.*AK

CONSUMER STATES WHILE DRIVING AT ANY SPEED, THERE WAS A STRONG SMELL OF CHEMICAL FUMES IN THE PASSENGER COMPARTMENT. THE DEALER HAD INSPECTED VEHICLE, AND WAS UNABLE TO DUPLICATE OR CORRECT THE PROBLEM. *AK THE DEALER DUPLICATED THE PROBLEM AND SAID THAT IT WAS NOT ACCEPTABLE. THE RIGHT FRONT WHEEL CENTER HAD FADED. *SCC *JB

FOUL FUMES ENTER CABIN UPON ACCELERATION. THIS OCCURS WITH HIGH OCTANE GAS OR WITHOUT HIGH OCTANE GAS. ONLY USE 93 OCTANE, BUT DUE TO SEVERAL OTHER COMPLAINTS TRIED LOWER OCTANE AND STRONG ODOR CONTINUED. THESE FUMES ENTER CABIN WITH ALL WINDOWS CLOSED, AIR VENTILATION ON RECIRCULATION AND WITH AIR CONDITIONG/HEAT OFF. MAKES BREATHING VERY DIFFICULT AND BECOME LIGHT HEADED OR HEADACHE. THIS IS NOT JUST A "SMELL" BUT LITERAL GAGGING FUMES.

TERRIBLE SULFUR SMELL ON ACCELERATION OF 2003 4RUNNER 6 CYLINDER SPORT. MOST NOTICEABLE WHEN THE REAR WINDOW IS DOWN. COMPLAINED TO DEALER TWICE. TOLD IT WAS THE GAS I WAS USING TWICE. TRIED NUMEROUS DIFFERENT BRANDS OF GAS WITH NO IMPROVEMENT. I DON'T BELIEVE ANY OF THIS. THERE MUST BE SOMETHING WRONG WITH THE CATALYTIC CONVERTER OR ANOTHER EXHAUST COMPONENT. WONDERING IF THE EXHAUST SMELL COULD CONTAIN CARBON MONOXIDE! *NLM
