2004 Toyota Highlander Engine

THERE IS A SULFUR SMELL WHEN I STOP OR BACK UP ON HILLS. THE DEALER SAID THAT THEY WOULD REPLACE THE CATALYTIC CONVERTER (PARTS ARE ON ORDER) AND THAT THIS WAS A DEFECT IN SOME VEHICLES. IF AN OWNER MENTIONS THE SMELL, THEY DO THE REPAIR UNDER WARRANTY. SHOULDN'T OWNERS BE MADE AWARE OF THE PROBLEM? *NM

WHILE RESEARCHING ANOTHER MATTER CONCERNING MY 2004 TOYOTA HIGHLANDER ON YOUR SITE, I READ COMPLAINT #10161055 CONCERNING A HESITATION PROBLEM THE OWNER WAS HAVING AND WANTED TO SAY THAT I HAVE EXPERIENCED THE SAME PROBLEM. IT IS NOT CONSTANT, HOWEVER IT DOES HAPPEN FREQUENTLY. *JB

MY 2004 TOYOTA HIGHLANDER HESITATES FOR A COUPLE OF SECONDS WHEN I ACCELERATE FROM ABOUT 40 TO 50 MPH SUCH AS GETTING ONTO A FREEWAY. I HAVE NEVER EXPERIENCED THIS IN ANY OTHER VEHICLE. I FIND THIS HESITATION TO BE VERY DISCONCERTING AND MAKES ME WORRY ABOUT MERGING INTO TRAFFIC. *JB

EXCESSIVE SULFUR DIOXIDE IN 2004 V6 TOYOTA HIGHLANDER, THERE IS ALREADY A TSB ON THE V4, BUT I OWN A V6 AND HAVE HAD THIS PROBLEM FOR ALMOST A YEAR NOW (STOP AND GO AND ACCELERATION, THERE IS A ROTTEN-EGG SMELL). I'VE BEEN TOLD BY 2 TOYOTA SERVICE STATIONS THAT IT IS THE GAS. THIS IS DEFINITELY NOT THE CASE. I'VE TRIED EVERY TYPE OF GAS AVAILABLE.

ENGINE HESITATION AND DELAYED ACCELERATION. *NM
