2008 LEXUS IS Complaints

PER THE FORUMS AND USED FB GROUPS, ALL ISFS YEAR MODELS 2008-2014 ARE AFFECTED THE 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. 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. I PERSONALLY HAD THIS ISSUE ON MY 2008 AND KNOW AT LEAST 100 OWNERS WHO HAVE ALSO HAD THIS ISSUE FIXED. I AM SURE MANY MORE ARE OUT THERE. *TR

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.

IT IS KNOWN AS THE VALLEY PLATE LEAK. AND IT'S RADIATOR FLUID LEAKING OUT WHICH CAUSES DAMAGE TO THE COMPRESSION AND ALSO CAUSES THE VEHICLE TO OVER HEAT EASILY. IT HAPPENED WHEN I LET THE CAR SIT AND STARTED IT AND I NOTICED THE VALLEY PLATE STARTED LEAKING.

THE SRS/AIRBAG LIGHT ILLUMINATED UPON STARTUP OF MY CAR, CODE B1861 DRIVER SIDE KNEE AIRBAG SQUIB OPEN.

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.

SUNROOF GLASS EXPLODED FOR NO REASON, SENDING GLASS PARTICLES INSIDE THE CAR WHILE TRANSPORTING MY INFANT DAUGHTER AND DRIVING. IT IS A MIRACLE NOBODY GOT HURT. THERE IS DOCUMENTED CASES OF SUNROOF GLASS EXPLODING ON LEXUS CARS CLASS ACTION LAWSUITS. MY CAR HAS BEEN AT THE DEALER BY REQUEST OF LEXUS USA REPRESENTATIVE SCOTT MURPHY SINCE LAST FRIDAY 11/15 AND STILL NO RESOLUTION. THE SAFETY OF VEHICLE OWNERS SHOULD NOT BE BARGAINING CHIP. THESE EXPLOSION CAN CAUSE SERIOUS DAMAGE TO VEHICLE OPERATOR AND OCCUPANTS.

OVER TIME, THE REARVIEW MIRROR HAS DARKENED WITH BLACK SPOTS AND LINES MAKING IT DIFFICULT TO SEE DURING THE DAY. LEXUS IS AWARE OF THE PROBLEM, BUT WILL NOT REPLACE THE MIRROR WITHOUT A RECALL. THE DEFECT CAN BE SEEN ON REARVIEW MIRRORS FOR SALE ON EBAY. I WAS ADVISED BY LEXUS SERVICE THAT IF IT DOESN'T PASS SAFETY CHECK INSPECTION TO STICK ON A TEMPORARY MIRROR. THEY KNOW THERE IS A PROBLEM AND IT IS A SAFETY ISSUE. THERE MUST BE A RECALL BEFORE SOMEONE DIES. I FIND MYSELF LOOKING LONGER INTO THE MIRROR, TAKING MY EYES OFF THE ROAD, TO DISCERN THE TRAFFIC BEHIND. I TOOK PICTURES, BUT ON EBAY, IF YOU LOOK CLOSE, YOU CAN SEE THE SPOTTING AND LINES ON THE USED MIRRORS FOR SALE. IT'S NOT AN ISOLATED INCIDENT. ESPECIALLY BY THE COMPASS IN THE RIGHT HAND SIDE THERE ARE NOTICEABLE PARALLEL DIAGONAL LINES. THE REST OF THE MIRROR IS SPOTTY WITH LINES AND DARK.

AFTER DRIVING THROUGH A DEEPER PUDDLE ON THE ROAD MY ELECTRON POWER STEERING STARTED TO WORK INTERMITTENTLY AND AFTER STOPPING BRIEFLY TO BUY SOME SNACKS, MY ELECTRONIC POWER STEERING QUIT COMPLETELY. IT NOW NO LONGER WORKS AT ALL, AND THE ONLY WAY TO STEER IT IS WITH MANUAL (VERY HEAVY) STEERING. IT HAS BEEN SITTING IN THE DRIVEWAY FOR THE PAST 3 WEEKS.
