IN DECEMBER OF 2002, WE PURCHASED A 2003 TOYOTA 4RUNNER SPORT. ALMOST IMMEDIATELY WE NOTICED A STRONG SULPHUR SMELL LEAKING INTO THE CABIN WHEN THE VEHICLE WAS IN MOTION. WE TOOK IT TO BACK TO PEFORMANCE TOYOTA WHERE WE PURCHASED IT AND HAD IT CHECKED OUT. THE MAINTENANCE MANAGER SAID THAT THE VEHICLE CHECKED OUT FINE, HANDED US A COPY OF A SERVICE BULLETIN #EG003-03 AND SUGGESTED WE CHANGE GAS. WE TRIED EVERY GAS AT EVERY GAS STATION WE COULD FIND AND IT ONLY GOT WORSE. MY WIFE HAD BEEN USING THE VEHICLE TO CAR POOL OUR TWO DAUGHTERS, ALONG WITH OTHER CHILDREN, HOME FROM SCHOOL. ONE OF THE CHILDREN GOT PHYSICALLY ILL (WE LATER FOUND OUT THAT HE SUFFERS FROM MIGRAINS, AND THE ODOR WAS TRIGGERING HIS ATTACTS), SO WE HAD TO PULL OUR DAUGHTERS OUT OF THE CAR POOL. IN ORDER TO LIMIT MY DAUGHTERS' EXPOSURE TO SULPHUR DIOXIDE, I AGREED TO USE THE TOYOTA AND LET MY WIFE USE MY DAKOTA TO TAKE THE GIRLS TO/FROM SCHOOL (IT DOESN'T STINK). AFTER DRIVING THE TOYOTA TO WORK FOR CLOSE TO A YEAR NOW, I HAVE EXPERIENCED HEALTH PROBLEMS AND HAVE RECENTLY BEEN DIAGNOSED WITH ASTHMA BY MY PHYSICIAN (WHICH I'VE NEVER HAD BEFORE). MY ASTHMA MEDICATION COSTS ME $158 PER MONTH AND I HAVE RESEARCHED CAUSES OF ASTHMA, AND HAVE FOUND THAT THIS SULPHUR SMELL IS A POSSIBLE TRIGGER FOR IT. I HAVE SINCE PURCHASED A USED VEHICLE TO DRIVE BACK AND FORTH TO WORK, AND THE $37,000 TOYOTA SITS IN THE GARAGE BECAUSE NO ONE CAN STAND TO DRIVE IT. HELP!!!!! *AK

TERRIBLE SULPHUR SMELL IN THE CABIN. WINDOWS ARE ALWAYS UP DUE TO 3 OF 4 MEMBERS HAVING ASTHMA. MAKES ALL PASSENGERS SICK TO STOMACHS AND HEADACHES. WANT FULL PURCHASE PRICE BACK FOR THIS VEHICLE. CANNOT DRIVE ANYLONGER. VERY UPSETTING FROM A TOYOTA PRODUCT. HAVE BEEN TO DEALER 3 TIMES.
AFTER A FEW WEEKS OF OWNERSHIP THE CONSUMER NOTICED THAT THE CABIN WOULD FILL UP WITH SULFUR DIOXIDE FUMES. *PH THESE FUMES HAVE CAUSED RESPIRATORY ISSUES FOR THE CHILDREN THAT RIDE IN THE VEHICLE. *NM
VIBRATION IN STEERING, MOST PREVALENT AROUND 70 MPH. STARTED AT 15,000 MILES. REBALANCED TIRES 3 TIMES AND DEALER DETERMINED THAT OEM TIRES WERE BAD. TRIED NEW TIRES AND THE PROBLEM PERSISTS. BELIEVED TO BE SAME AS LEXUS GX 470 PROBLEM WITH TSB FIX ST004-04. NO TOYOTA TSB YET. *JB
ROTTEN EGG/SULFUR SMELL/EXHAUST ENTERING CABIN OF VEHICLE EVEN IF WINDOWS ARE UP.HAVE HAD PROBLEM SINCE PURCHASE OF VEHICLE IN AUG,2003. *AK
