2008 Toyota 4Runner Engine

EXHAUST MANIFOLD CRACKING ON TOYOTA V8 4.7 ENGINE ALLOWING EXHAUST FUMES INTO THE CABIN AND CAUSING DIZZINESS. WHEN DOING MY RESEARCH IVE SEEN PAGES AND PAGES OF THIS ISSUE KNOWN TO TOYOTA ABOUT THE 4.7 ENGINE THAT IS USED IN A NUMBER OF THERE MODELS FROM LEXUS TO THE TUNDRA PICK LINES AND ANYTHING THAT USES THE 4.7 ENGINE. THIS IS DEADLY BEING IN THE MIDWEST AND YOU HAVE YOUR WINDOWS UP AND HEAT ON IN THE WINTER OR SUMMER WITH AC ON. THANK YOU FOR YOUR TIME

MY TRUCK HAS HAD A SULPHUR SMELL FOR A LONG WHILE. I WAS ADVISED THAT THERE IS A SERVICE BULLETIN ON IT. T-SB-0346-09. I CONTACTED TOYOTA AND RECEIVED A CASE # FROM SUSAN ON AUGUST 28,2017. THAT # IS 1708280670. SHE ADVISED ME THAT I AM 3,000 MILES PAST THE MILAGE THAT TOYOTA ACCEPTS. THIS IS AN EMISSION ISSUE AND I FEEL THAT THEY SHOULD ASSIST IN THE REPLACEMENT COST. THE SERVICE BULLETIN HAS TOYOTA REPLACING A FRONT AND REAR PIPE ASSEMBLY WHICH INCLUDES CATALYTIC CONVERTERS. THE ISSUE HAS BEEN KNOWN FOR A WHILE AND THEY SHOULD HAVE RECALLED THIS SYSTEM NOT WAITED FOR PEOPLE TO COMPLAIN. BY NOT RECALLING IT THEY AVOID MAKING LEGITIMATE EMISSION/ENGINE REPAIRS. THE SULPHUR SMELL NOW HAPPENS MOST OF TIME THAT I DRIVE IT NOW. I DO NOT KNOW WHAT ELSE THAT I CAN DO. THE TOYOTA DEALER HAD ADVISED ME TO CONTACT TOYOTA.

MY TOYOTA 4RUNNER HAS A CONSISTENT AMMONIA SMELL THAT LEAKS INTO THE CABIN. THIS HAS GONE ON FOR A MONTH AND HATCH TOYOTA DENIES IT'S A PROBLEM. MY WIFE AND I FEAR FOR OUR HEALTH BECAUSE OF THIS ODOR. THE FORUMS REPORT THIS PROBLEM AS FAR BACK AS 2003, BUT TOYOTA SAYS THEY ARE UNAWARE OF ANY PROBLEM. *TR
