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.

TL* THE CONTACT OWNS A 2008 LEXUS IS250/350. WHILE DRIVING 60 MPH THE VEHICLE SHUDDERED AND SHUT OFF WITH AN UNKNOWN WARNING LIGHT ILLUMINATED. THE CONTACT WAS ABLE TO RESTART THE VEHICLE AFTER SEVERAL ATTEMPTS. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC BUT WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 15,000.

2008 LEXUS IS 250 EXHIBITS A BRIEF RATTLE NOISE (APPROXIMATELY 1-3 SECONDS) AT START-UP. THE ISSUE WAS DIAGNOSED BY A LEXUS DEALERSHIP WHICH RECOMMENDED REPLACING THE CAM GEAR ASSEMBLY ASSOCIATED WITH THE VARIABLE VALVE TIMING (VVT) SYSTEM. THE VVT GEAR HOUSING AND SPROCKET COULD SEPARATE AND RESULT IN THE ENGINE STOPPING WHILE THE VEHICLE IS BEING DRIVEN, INCREASING THE RISK OF A CRASH. THE SAME SYMPTOMS, DIAGNOSIS, AND RECOMMENDED REPAIR WERE SUBJECT OF THE TOYOTA SAFETY RECALL 13V-395. THE RECALL EXCLUDED THE 2008 LEXUS IS 250, HOWEVER INCLUDED THE 2006-2011 LEXUS IS 350, 2010-2011 LEXUS IS 350C, AND THE 2006-2011 GS 350 MODELS. THE SAME DIAGNOSIS AND RECOMMENDED REPAIR WAS DETERMINED TO BE A SAFETY ISSUE IN THE MODELS ABOVE, BUT IS NOT IN THE 2008 LEXUS IS 250?

I TOOK MY CAR TO THE LOCAL DEALER FOR THE CARBON BUILDUP RECALL IN THE MOTOR. THEY REBUILT PARTS OF THE INTERNAL MOTOR. AFTER THEY REBUILT THE MOTOR FOR CARBON BUILD UP, MY ENGINE LIGHT STARTED TO LIGHT UP FOR BAD CATALYTIC CONVERTER. I TOLD THEM THAT THE LIGHT NEVER SHOWED UP BEFORE AND COULD'VE WENT BAD FROM ALL OF THE MILES OF CARBON BUILD UP THAT DAMAGED THE CATALYTIC CONVERTER. THEY COULDN'T REPAIR THE CATALYTIC CONVERTER BECAUSE I WAS OUT OF THE WARRANTY PERIOD.
