2008 Lexus Is

TO WHOM IT MAY CONCERN. WITHIN THE IS-F(2008-2014). MEMBERS ARE EXPERIENCING CRACKED HEADERS MANIFOLD. MEMBERS REPORT SMELLING BAD EGGY PRE-CAT FUMES ODOR. THIS SEEMS TO BE AN ISSUE FOR PEOPLE WITH MID TO HIGH MILEAGE. THE OTHER ISSUE EVERY MEMBER IS EXPERIENCING ARE LEAKING VALLEY PLATE SEAL. PINK COOLANT CAN BE OBSERVED DRIPPING IN MINOR CASES AND LEAKING IN MAJOR CASES. CASES OF A POOL OF COOLANT ON OWNERS DRIVEWAY/GARAGES. THIS CAN EASILY CAUSE A FIRE.

LEXUS ISF, YEAR MODELS 2008-2014, ARE AFFECTED BY A VALLEY PLATE LEAK DUE TO THE FACT THAT TOYOTA/LEXUS UTILIZED THE IMPROPER SEALANT AND USED THE IMPROPER AMOUNT, LEADING TO THE HEAT EXCHANGER LEAKING COOLANT ONCE THE ORIGINAL, INADEQUATE SEALANT BEGINS TO DISINTEGRATE. THIS COULD CAUSE A CONDITION WHERE THE ENGINE COULD FAIL AND SOMEONE COULD GET HURT. THIS ISSUE IS VERY PROMINENT IN THE COMMUNITY (EVERY LEXUS FACEBOOK GROUP AND FORUM HAS DOCUMENTED THIS INFORMATION) - MOST ISFS DEVELOP THIS UNDER 100K MILES. FURTHERMORE, ALL ISFS WILL EVENTUALLY HAVE A CRACKED RH MANIFOLD ON THE #8 RUNNER. THIS CAN CAUSE A FIRE HAZARD IN ADDITION TO CARBON MONOXIDE POISONING. MY 2008 ISF HAS BEEN LEAKING COOLANT FOR ABOUT 15K MILES, PROGRESSIVELY GETTING WORSE (INSPECTED EVERY OIL CHANGE). IN ADDITION, I HAVE TO START TOPPING OF THE COOLANT EVERY WEEK. LEXUS DEALER QUOTED THIS REPAIR AT ALMOST $2000. *TR

MY LEXUS ISF HAS A CRACKED PASSENGER SIDE MANIFOLD WHICH IS VERY AUDIBLE ON STARTUP AND BEGINNING SIGNS OF A VALLEY PLATE COOLANT LEAK, WHICH WILL EVENTUALLYLEAD TO ENGINE FAILURE. THESE CARS WERE MADE IN VERY LOW NUMBERS, HOWEVER OUR CAR ENTHUSIAST COMMUNITY IS EXPERIENCING THESE FAILURES IN A HIGHER THAN ACCEPTABLE NUMBERS OF THIS RARE VEHICLE. EACH REPAIR IS MANY THOUSANDS OF DOLLARS AND (VALLEY PLATE 2K-5K) (MANIFOLD QUOTED AT 22 HOURS LABOR AND 1400 FOR THE PART FROM LEXUS) TAKEN INTO ACCOUNT THE LOW PRODUCTION NUMBER AND HIGH RATE OF FAILURE, THIS MUST BE ADDRESSED. LEXUS HAS FAILED TO WORK WITH ME SHARING THE BILL.
