THE TRANSMISSION ON MY CAR HAS ISSUES JERKING WHEN IN GEAR AND STOPPING WHEN IN USE. I TOOK MY CAR TO A CERTIFIED LEXUS DEALER AND THEY COULD NOT REPAIR IT. I'M SURE BECAUSE IT WAS NO LONGER UNDER WARRANTY. I TOOK IT TO A TRANSMISSION MACHANIC AND I BOUGHT A 2006 IS250 USED TRANSMISSION FROM A CAR THAT WAS TOTALED THAT HAD LESS MILES AND WAS TOTALED BECAUSE THE FRAME WAS BENT BECAUSE IT WAS REAR ENDED. IN LESS THAN A YEAR SAME PROBLEM TRANSMISSION AGAIN! I SPENT $4500 THE FIRST GO AROUND I COULDN'T AFFORD THAT AGAIN. I HAD TO BUY ANOTHER CAR FOR WHAT I PAID TO REPAIR THE LEXUS. I'VE CHECKED FOR RECALLS YEAH MY DASH HAS MELTED AND ALL OF THE OTHER RECALLS! I CAN'T GET THOSE CORRECTED!! I'M STARTING A CLASS ACTION LAWSUIT!!! I'VE SPENT TO MUCH MONEY ON A HIGH CLASS TOYOTA THAT HAS MORE PROBLEMS THAN ITS WORTH!!!!

AUTOMATIC TRANSMISSION. WHEN SLOWING TO A STOP OR ANYTIME (EVERYTIME) THE CAR NEEDS TO AUTO DOWNSHIFT FROM 2ND TO 1ST THE CAR HARD SHIFTS AND THE ENTIRE CAR JERKS REALLY HARD CAUSING ALMOST WHIPLASH. THIS IS A WIDELY DISCUSSED ISSUE WITH IS AND GS MODELS ON MANY FORUMS. NEW ECU UNITS NEEDED EACH TIME COSTING THOUSANDS.

THE CAR WAS SHAKING AND WOULD NOT EXCELERATE OVER 40MPH. IT WAS BROUGHT IN TO LEXUS OF POHANKA IN DECEMBER OF 2016. THEY PERFORMED A TOP ENGINE CLEAN. THE CAR STARTED HAVING THE SAME ISSUES IN THE BEGINNING OF 2017. I CALLED LEXUS CUSTOMER SERVICE AND OPENED A CASE AS I WAS TOLD THERE WAS A RECALL ON A MANUFACTURING DEFECT OF THE PISTONS. I HAD PAID $1500.00 FOR THE WORK PERFORMED. I WAS TOLD A SHOULD HAVE RECEIVED A LETTER IN REGARD TO THIS PROBLEM. LEXUS WAS CALLING IT A CUSTOMER SUPPORT PROGRAM. I NEVER RECEIVED THE LETTER BUT REPEATEDLY ASK LE US TO REIMBURSE ME AND SOLVE THE PISTON MISFIRE. I HAVE ALL OF MY EMAILS TO SUPPORT MY CASE. LEXUS STOPPED REPLYING TO THEM. THE CAR AT THIS POINT IS STILL SHAKING AND THE ENGINE LIGHT IS FLASHING. WE HAVE BEEN INSTRUCTED BY LEXUS IN THE PAST NOT TO DRIVE WHEN LIGHT IS FLASHING. AT THIS TIME I DO NOT KNOW WHERE TO TURN. ANY HELP WOULD BE GREATLY APPRECIATED. I AM AWARE THAT MANY OF THESE MODELS AND OTHERS HAVE HAD THE WORK PERFORMED OR NEW ENGINES.

I HAVE A UNSAFE VEHICLE THAT IS DANGEROUS FOR MYSELF AND THE PUBLIC. THE DEALERSHIP HAS FAIL TO TAKE RESPONSIBILITY FOR THE PROBLEM. THERE IS A RECALL FOR THE PROBLEM AND IT WAS EXTENDED AS WELL. ( CARBON BUILDUP) . THE REGISTRATION HISTORY ON THE VEHICLE IS VERY STRANGE, IT DOES NOT SEEM TO BE ACCURATE, I BELIEVE THIS VEHICLE WAS A DEFECT AND THE DEALERSHIP HAS TAMPERED THE VEHICLE TO COVER THE HISTORY. THE VEHICLE SERVICE HISTORY HAS BEEN PURGE AND DELETED FOR UNKNOWN REASON. I AM GETTING DIFFERENT ANSWERS AND NO HELP WITH THE PROBLEM. IT HAS CAUSE ME A LOT OF DISTRESS AND CONCERN, I HAVE SPENT THOUSANDS OF DOLLARS TRYING TO MAKE IT SAFE BUT FROM RESEARCH THIS IS A COMMON DEFECT FOR THIS PARTICULAR VEHICLE AND IT CAN NOT BE REPAIRED.

I NOTICED A BLACK SPOT IN MY REAR VIEW MIRROR ONE DAY AND DID NOT THINK ANYTHING OF IT, HOWEVER THE ONE SPOT TURNED INTO MULTIPLE STREAKS. IT'S GETTING HARDER TO SEE OUT OF THE MIRROR WHICH TO ME IS A SAFETY ISSUE. I NOTICED THAT THERE ARE MANY COMPLAINTS ON THIS ISSUE AND THERE SHOULD BE A RECALL ON THIS DEFECT AS WELL. I HAVE TO MAKE AN APPOINTMENT FOR THE RECALLS ON THE MELTING DASHBOARD AND DOORS AND ENGINE. LEXUS SHOULD REALLY TAKE CARE OF THIS PROBLEM. I HAVE PURCHASED SEVERAL NEW VEHICLES HOWEVER I HAVE HAD MORE PROBLEMS WITH THIS CAR THAN I DID WITH MY OTHER CARS.

THE CHECK ENGINE, CHECK VSC LIGHT WOULD INTERMITTENTLY COME ON WHEN I TURNED ON MY CAR AND SOMETIMES WHILE DRIVING. THIS HAS HAPPENED SINCE I PURCHASED MY CAR IN 2006. I BROUGHT MY CAR IN FOR THE RECALL BUT THEY COULDN'T MAKE THE LIGHT COME ON WHEN THEY HOOKED UP THEIR COMPUTERS TO THE COMPUTERS IN MY CAR. I RECENTLY BROUGHT MY CAR TO ANOTHER DEALERSHIP TO PERFORM THE RECALL OF THE DASHBOARD AND SIDE PANELS AND THE PROBLEM FINALLY HAPPENED WHILE THEY HAD THE CAR IN THEIR POSSESSION. THEY TESTED IT AND SAID THIS PROBLEM WOULD HAVE BEEN COVERED BY A RECALL HAD IT NOT EXPIRED. THEY SAID THE REASON IS THAT CARBON BUILDUP IN THE FIRST, THIRD, AND FIFTH CYLINDERS ARE CAUSING THIS PROBLEM. WHY DIDN'T THEY DISCOVER THIS WHEN I TOOK MY CAR IN FOR THAT RECALL THE FIRST TIME? BECAUSE IT DIDN'T EXHIBIT THE PROBLEM AT THE TIME DOESN'T MEAN IT DIDN'T HAVE THE ISSUE. NOW THEY SAID THEY CANNOT FIX IT BECAUSE THE RECALL EXPIRED?! HOW IS THAT FAIR OR SAFE?!?!?!?

BARELY 1 YEAR LATER I EXPERIENCED THE SAME PROBLEM, I BROUGHT IT BACK TO THE DEALER AND WAS TOLD THEY COULD NOT REPLICATE THE ISSUE. 2 WEEKS AGO THE PROBLEM HAPPENED AGAIN SO I BROUGHT IT BACK TO THE DEALER, NOW THEY INFORM ME THE CAR NEEDS A NEW ENGINE AND IS GOING TO COST OVER 4000 DOLLARS FOR A FIX THEY DID NOT PERFORM CORRECTLY THE FIRST TIME.

I TOOK MY VEHICLE IN TO A LEXUS DEALERSHIP ON MARCH 15, 2013 BECAUSE THE ENGINE HAS POWERED DOWN WHILE DRIVING & THE CHECK ENGINE AND VSC INDICATORS CAME ON SIMULTANEOUSLY, THE CAR IS ALSO IDLING HARD. I HAD THE VEHICLE INSPECTED AND IT WAS FOUND TO MISFIRE BY THE TECHNICIANS AT THE DEALERSHIP. I WAS TOLD THAT THIS IS A MASSIVE RECALL AND THAT MY PARTS WILL NOT COME IN FOR EIGHT MONTHS. I AM AFRAID TO DRIVE MY VEHICLE WHICH IS WHY I BROUGHT IT TO THE DEALERSHIP AND DO NOT UNDERSTAND WHY THE COMPANY WILL NOT LOAN ME A VEHICLE WHILE THIS MANUFACTURING DEFECT IS CORRECTED.

FOR 3-YEARS WE HAVE COMPLAINED TO THE DEALERSHIP REGARDING THE MUSTY SMELL COMING FROM THE A/C VENTS. WE WERE ADVISED BY THE DEALERSHIP TO CUT OFF THE A/C BEFORE ARRIVING HOME TO ALLOW THE UNIT TO DRAIN. WE ALSO WERE ADVISED TO SPRAY LYSOL INTO THE OUTSIDE COWL VENTS WHICH DID IMPROVE THE ODOR BUT THIS A/C MUSTY SMELL HAS ALWAYS BEEN AN ISSUE AND IS ALL OVER THE INTERNET. ON 12/20/2011, WE NOTICED WATER WAS APPARENTLY ENTERING THE PASSENGER COMPARTMENT. THE CARPET WAS WET AND THERE WAS EXCESSIVE MOISTURE AND WATER UNDER CARPET. UPON NOTICING THIS PROBLEM WE SCHEDULED AN APPOINTMENT WITH THE DEALERSHIP. I WAS ADVISED THAT MOST LIKELY, THE A/C DRAIN FLAP WAS STUCK AND CORRECTION FOR THIS DEFECT REQUIRED REMOVAL OF THE DRAIN FLAP TO ALLOW THE DRAIN TO FLOW AND NOT BACK UP AND ENTER THE PASSENGER COMPARTMENT. THE DEALER STATED THIS DEFECT HAS OCCURRED BEFORE INVOLVING THE IS250. COST TO CORRECT THIS DEFECT WAS $240 BECAUSE THE TRANSMISSION HAD TO BE DROPPED TO ACCESS THE DRAIN LINE. REMOVING THE WATER/MOISTURE AND DRYING THE CARPET WAS ESTIMATED AT $2K. AGAIN, THIS OBVIOUS DEFECT IS ALL OVER THE NET AND APPARENTLY WELL KNOWN BY THE DEALERSHIP. ALL LEXUS OWNERS SHOULD BE NOTIFIED BY LEXUS SO ALL CAN AVOID THIS POTENTIAL HEALTH ISSUE INVOLVING MOLD AND THE HIGH COST OF REPAIR. IF THE WATER IS NOT NOTICED AND WATER CONTINUES TO BUILD UP IN THE A/C AND UNDER THE CARPETS SERIOUS MOLD RELATED HEALTH ISSUES COULD OCCUR. I DON'T KNOW HOW LONG OUR CAR LEAKED OR BACKED UP WATER BUT A MUSTY SMELL FOR THE PAST 3-YEARS HAS BEEN NOT ONLY OFFENSIVE BUT DANGEROUS CONSIDERING THE HEALTH HAZARDS ASSOCIATED WITH MOLD HERE IN FLORIDA.I RESPECTFULLY SUBMIT THAT THIS DEFECT SHOULD BE ADDRESSED IMMEDIATELY.

I HAVE A 2006 LEXUS IS250. I NOTICED "ROUGH" STARTS AND IDLE. THIS WAS AT OR AROUND 65K MILES. I ASSUMED IT WAS RELATED TO SUPER COLD WEATHER OR "BAD" GAS (AFTER THE CAR SAT UNUSED FOR 2-3 DAYS+) AT AROUND 84K MILES DURING WARM WEATHER - I EXPERIENCED BOTH A ROUGH START AND STALLING AT A STOP SIGN. I TOOK THE VEHICLE INTO MY LOCAL DEALERSHIP WHERE IT HAS BEEN METICULOUSLY MAINTAINED. THEY DID AN EXTENDED DIAGNOSTIC (KEPT THE CAR OVER A LONG WEEKEND) AND ADVISED MY CAR WAS NOT "FIRING" 65-85% OF THE TIME AND THAT IT WAS CAUSED BY THE VALVE SPRINGS. THIS IS A $5,000 REPAIR. LEXUS CLAIMED BECAUSE THE ISSUE WAS OUTSIDE THE 70K MIKE WARRANTY THEY WOULD PAY FOR THE "PARTS" OF ROUGHLY $4,000 AS "GOODWILL" BUT I WOULD BE RESPONSIBLE FOR THE LABOR AT $945. I DID A SEARCH FOR RECALLS AND LEARNED THAT THE EXACT ISSUE IS UNDER RECALL FOR OTHER MODELS INCLUSIVE OF THE IS350 V6 - WHICH THE COMPANY REGULARLY REFERS TO AS MY CAR'S "SIBLING" AND HAS SHARED PREVIOUS RECALLS WITH. I'VE CONTACTED LEXUS DIRECTLY AND THEY HAVE ADVISED THE OFFER IS FINAL. THEY HAVE REFUSED MY REQUEST TO SPEAK WITH THE MANUFACTURING REP. I BELIEVE THIS "STALL" ISSUE IS A SIGNIFICANT SAFETY CONCERN (PER THE RECALL NOTED) I'VE ASKED LEXUS WHETHER OR NOT THEY HAVE RESEARCHED THIS ISSUE ON THE V6 250 FOR WHICH I'VE NOT RECEIVED A RESPONSE. I BELIEVE THAT LEXUS WOULD HAVE USED THE EXACT SAME MANUFACTURER FOR THESE VALUE SPRINGS AND OR VERY SIMILAR DESIGN SPECIFICATIONS. IT IS INCOMPREHENSIBLE THAT GIVEN THIS SPECIFIC DIAGNOSIS THEY WOULD NOT RESOLVE THIS IMMEDIATELY. I BELIEVE ABSENT A NHTSA INVESTIGATION LEXUS WILL CONTINUE TO HOLD CUSTOMERS HOSTAGE TO PAY FOR THEIR SAFETY ALTHOUGH EVERY INDICATION IS THAT THIS IS A DESIGN/MANUFACTURING DEFECT FOR THIS MODEL AS WELL.

I OWN A 2006 LEXUS IS250 AND THERE IS A PROBLEM THAT I CANNOT SEE TO HANDLE NOR THE DEALER CAN HANDLE. THE PROBLEM WITH THE CAR IS THAT WHEN I'M GOING OVER 60 TO 65 MPH THE CHECK ENGINE LIGHT BLINKS AND THE VSC LIGHT COMES ON. THE CAR DOES NOT ACCELERATE AND JUST THE RPM WOULD GO UP. I TOOK THE CAR IN TO THE DEALER WITH EXTENDED WARRANTY IN HAND ON 4 NOW 5 DIFFERENT OCCASIONS AND EVERYTIME I'M HEARING DIFFERENT STORIES. HERE IS THE LIST. * MAY 22, 2009: 60,000 MILE SERVICE DONE.* SEPT 6, 2009: TOOK THE CAR IN FOR "CHECK VSC & CHECK ENGINE". NEXT DAY THEY TOLD ME NOTHING WAS WRONG WITH THE CAR.* OCT 10, 2009: TOWED CAR TO DEALERSHIP. "CHECK VSC & CHECK ENGINE" LIGHT CAME ON AGAIN.PULLED OVER ON THE HIGHWAY 3 TIMES TO RESET BUT THE LIGHTS DID NOT GO AWAY. PULLED OVER TWICE EARLIER THAT DAY, TWICE THE DAY BEFORE ALSO.* OCT 14, 2009: (LEXUS TOLD YOU THAT THE ISSUES WERE RESOLVED BY SWAPPING THE ENGINE COILS THE DAY OR TWO BEFORE. NO CHARGES.) I REQUESTED AN EMISSIONS TEST BEFORE I CAME TO PICK IT UP. LEXUS CALLED BACK AND TOLD ME THAT THE ENGINE LIGHT CAME BACK ON AGAIN DURING THE EMISSIONS TEST. STILL LOOKING FOR THE PROBLEM.* OCT 18, 2009: LEXUS CALLED, TOLD ME THAT THE PROBLEM WITH THE ENGINE IS BECAUSE OF THE CARBON BUILDUP. THEY WERE GOING TO COVER THE VALVE SPRINGS BUT I WOULD HAVE TO PAY FOR THE CLEANUP WHICH IS $ 960. NOT COVERED BY EXT. WARRANTY. 2 OTHER DEALERS TOLD ME THAT THE CARBON BUILDUP CLEANUP WAS AN INJUNCTION SERVICE AND IT IS SUPPOSED TO ONLY COST 190 DOLLARS. THE FUNNY THING IS THAT THE DEALER WROTE THE PROBLEM IS CAUSED BY "CARBON BUILDUP CLEANUP?" WITH A QUESTION MARK. TOOK THE CAR AND HAD THE INJUNCTION SERVICE DONE. I TOOK THE CAR TO ANOTHER LEXUS DEALER AND THEY TOLD ME THAT WHILE THE OTHER DEALER WAS DOING THE COIL SWAP THEY CRACKED THE COVER FOR IT AND NOW GAS WAS LEAKING. HAD TO GET IT FIXED AND ALSO DID THE CARBON BUILDUP CLEANUP (INJUNCTION SERVICE). FEB 2010 SAME PROBLEM OCCURRED.

I WAS OPERATING MY 2006 LEXUS IS250 AWD AT VERY LOW SPEED IN A PARKING LOT WHEN THE ENGINE BEGAN TO SURGE. I COULD NOT BRING THE CAR TO A STOP USING THE BRAKE PEDAL AND COULD BARELY KEEP IT FROM CREEPING FORWARD. I SHIFTED INTO NEUTRAL AND THE ENGINE REALLY BEGAN TO ROAR, REVVING VERY HIGH, BUT I WAS THEN ABLE TO STOP THE CAR AND TURN IT OFF USING THE STOP/START BUTTON. WHEN I RESTARTED THE CAR IT OPERATED NORMALLY AND THE PROBLEM DID NOT RE-OCCUR. THE FLOOR MAT HAD NOTHING TO DO WITH THE PROBLEM, AS IT WAS A FACTORY MAT HELD IN PLACE BY THE LITTLE HOOKS, AND WAS NOT THE ALL WEATHER MAT. THE MAT WAS IN PLACE AFTER THE INCIDENT. I REPORTED THE OCCURRENCE TO MY DEALER, WARNOCK LEXUS, IN LIVINGSTON, N.J. THEY CHECKED THE CAR OUT AND FOUND NOTHING WRONG AND NO EVIDENCE OF ANYTHING WRONG IN THE COMPUTER'S MEMORY. THE PROBLEM DID NOT RECUR AND THE CAR WAS RETURNED TO LEXUS AT THE END OF THE LEASE. I NOW HAVE A 2009 IS250 AWD AND AM CONCERNED ABOUT THE REPORTS OF THIS PROBLEM. I DON'T FEEL THE FLOOR MAT HAD ANYTHING TO DO WITH IT. THE DATE BELOW IS APPROXIMATE, BUT LEXUS SHOULD HAVE A RECORD OF THE INCIDENT FROM THE DEALER SERVICE DEPARTMENT.

CAR STARTED TO RUN ROUGH, SLOWED DOWN, CHECK ENGINE LIGHT AND SBS LIGHT CAME ON (ITHOUGHT IT WAS AN OXYGEN SENSOR). BOOK SAYS TO TAKE TO DEALER IMMEDIATELY. I TOOK IT IN, THEY DID A CHECK, TOLD ME IT WAS A 'LOOSE GAS CAP'. A MONTH LATER - SAME THING HAPPENED. I TOOK IT BACK, THEY KEPT THE CAR FOR TWO WEEKS - TOLD ME THE VALVE SPRINGS WERE NOT THE CORRECT LENGTH AND HAD TO BE REPLACED.

I PURCHASED A 2006 IS 250 IN OCTOBER, 2005. THE VEHICLE HAS BEEN DRIVEN FOR 2,500 MILES. AFTER THE ENGINE WARMS UP, SMOKE AND A BURNED SMELL COME FROM THE ENGINE COMPARTMENT. THE FIRST TIME I BROUGHT THE PROBLEM TO THE DEALERS ATTENTION I WAS TOLD THAT EVERYTHING WAS NORMAL. I BROUGHT THE VEHICLE IN A SECOND TIME AND IT WAS DISCOVERED THAT OIL WAS LEAKING FROM THE PASSENGER'S SIDE VALVE COVER ONTO THE HOT EXHAUST MANIFOLD CAUSING THE OIL TO SMOKE AND BURN. THE VEHICLE IS NOW AT THE DEALERS SERVICE DEPARTMENT AND I AM BEING TOLD THAT THEY DO NOT KNOW HOW TO FIX THE PROBLEM AND THAT THEY HAVE NO PARTS TO USE FOR REPLACEMENT SINCE THE DESIGN IS SO NEW. THE PROBLEM IS RELATED TO THE HIGH OIL PRESSURE MAINTAINED BY THE ENGINE ACCORDING TO THE DEALER. THE ENGINE IS COVERED WITH PLASTIC PANELS AND I HAVE ADVISED THE DEALER THAT CONTINUAL LEAKAGE OF OIL ONTO THE HOT EXHAUST MANIFOLD WITH A PLASTIC COVER ON TOP OF THE ENGINE COULD RESULT IN AN ENGINE FIRE. SMOKE IS VISIBLE FROM THE ENGINE COMPARTMENT WHEN THE ENGINE IS RUNNING.
