Vehicle: 2008 Lexus IS350 Issue: Excessive oil consumption and fuel/exhaust odor I am experiencing what I believe is excessive oil consumption with my 2008 Lexus IS350. I’ve had to regularly add oil between scheduled oil changes, and I’ve noticed that the oil level is frequently low with no external leaks visible. I’m concerned that this may indicate a known issue with piston rings or internal engine components. In addition to the oil issue, I have recently started smelling strong gas or exhaust fumes while the engine is running, especially at idle or when the car is warm. I am worried that this may be related to catalytic converter damage caused by prolonged oil burning. I believe this may pose both a safety risk and an environmental concern, especially if the catalytic converter is compromised. I have not yet received any recall notices or service bulletins related to this issue, but I am aware that similar Toyota and Lexus models have had oil consumption problems tied to engine design.

UPON STARTING VEHICLE, ENGINE LOUDLY RATTLES FOR APROX. ONE SECOND AS IF SOMETHING IS LOOSE. THIS INSTANCE IS DIRECTLY IN LINE WITH LEXUS TSB "L-SB-0155-08" (Engine - Brief Engine Knock/Rattle On Cold Start Up). FURTHER INVESTIGATION SHOWS THIS IS A MAJOR CONCERN AS THIS INVOLVES A FAULTY CAMSHAFT ASSEMBLY.

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?

TOYOTA IS RECALLING CERTAIN MODEL YEAR 2006-2009 LEXUS IS AND MODEL YEAR 2006-2007 LEXUS GS VEHICLES. DUE TO INSUFFICIENT TIGHTENING OF THE FUEL PRESSURE SENSOR CONNECTED TO AN ENGINE FUEL DELIVERY PIPE WITH NICKEL PHOSPHORUS PLATING, THERE IS A POSSIBILITY THAT, OVER TIME, THE PRESSURE SENSOR COULD LOOSEN. IF LOOSENING OCCURS, FUEL COULD LEAK PAST A GASKET USED IN THE CONNECTION BETWEEN THE SENSOR AND THE PIPE AND THROUGH THE THREADED PORTION OF THE SENSOR.
Consequence & remedy
Consequence: FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL INSPECT FOR FUEL LEAKAGE FROM THE THREADED PORTION OF THE FUEL PRESSURE SENSOR AND IF A FUEL LEAK IS NOT CONFIRMED, DEALERS WILL FURTHER TIGHTEN THE FUEL PRESSURE SENSOR WITH THE PROPER TORQUE. IF A FUEL LEAK IS CONFIRMED, THE GASKET BETWEEN THE SENSOR AND THE FUEL DELIVER PIPE WILL BE REPLACED WITH A NEW ONE, AND THE SENSOR WILL BE TIGHTENED WITH THE PROPER TORQUE. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 7, 2011. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.
TOYOTA IS RECALLING CERTAIN MODEL YEAR 2004-2010 PASSENGER VEHICLES. THE ACCELERATOR PEDAL CAN GET STUCK IN THE WIDE OPEN POSITION DUE TO ITS BEING TRAPPED BY AN UNSECURED OR INCOMPATIBLE DRIVER'S FLOOR MAT.
Consequence & remedy
Consequence: A STUCK OPEN ACCELERATOR PEDAL MAY RESULT IN VERY HIGH VEHICLE SPEEDS AND MAKE IT DIFFICULT TO STOP THE VEHICLE, WHICH COULD CAUSE A CRASH, SERIOUS INJURY OR DEATH.
Remedy: TOYOTA FILED AN AMENDED DEFECT REPORT ON NOVEMBER 25, 2009, STATING THAT DEALERS WILL MODIFY THE ACCELERATOR PEDAL AND, ON CERTAIN VEHICLES, ALTER THE SHAPE OF THE FLOOR SURFACE UNDER THE PEDAL. THESE CHANGES ADDRESS THE RISK OF PEDAL ENTRAPMENT DUE TO INTERFERENCE WITH THE FLOOR MAT. REDESIGNED ACCELERATOR PEDALS WILL BECOME AVAILABLE BEGINNING IN APRIL 2010 AND DEALERS WILL REPLACE ANY MODIFIED PEDAL WITH THE NEW PEDAL IF DESIRED. ALSO, DEALERS WILL REPLACE ANY GENUINE TOYOTA OR LEXUS ALL-WEATHER FLOOR MATS WITH REDESIGNED ALL-WEATHER MATS, OR REPURCHASE THE PREVIOUS MATS FROM OWNERS WHO DO NOT WANT THE NEW ONES. ADDITIONALLY, SOFTWARE MODIFICATIONS WILL BE INSTALLED ON CAMRY, AVALON AND LEXUS ES 350, IS 350 AND IS 250 MODELS THAT WILL ENSURE THAT THE BRAKE OVERRIDES THE ACCELERATOR IN THE EVENT BOTH BRAKE AND ACCELERATOR PEDALS ARE APPLIED. TOYOTA WILL BEGIN MAILING LETTERS TO OWNERS ON DECEMBER 31, 2009. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331, LEXUS AT 1-800-255-3987.
TOYOTA IS RECALLING 214,570 MY 2006-2008 LEXUS IS, MY 2006-2007 GS AND MY 2007-2008 LS PASSENGER VEHICLES EQUIPPED WITH ALUMINUM FUEL DELIVERY PIPES (FUEL RAILS). ETHANOL FUELS WITH A LOW MOISTURE CONTENT WILL CORRODE THE INTERNAL SURFACE OF THE FUEL RAILS. AS THIS CONDITION PROGRESSES, THE ENGINE MALFUNCTION INDICATOR LIGHT MAY ILLUMINATE.
Consequence & remedy
Consequence: OVER TIME, THE CORROSION MAY CREATE A PINHOLE RESULTING IN FUEL LEAKAGE. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL INSPECT AND REPLACE THE FUEL DELIVERY PIPES FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING FEBRUARY 2009. OWNERS MAY CONTACT TOYOTA/LEXUS AT 1-800-255-3987.
