2010 Lexus RX Complaint Log

TL* THE CONTACT OWNS A 2010 LEXUS RX350. THE CONTACT STATED THAT WHILE STOPPED WITH THE BRAKES APPLIED, THE VEHICLE SURGED FORWARD APPROXIMATELY TWO TO THREE FEET. HEAVY PRESSURE WAS APPLIED TO THE BRAKES TO STOP THE VEHICLE. THE VEHICLE WAS LATER TAKEN TO AN AUTHORIZED DEALER, BUT THEY COULD NOT DIAGNOSE A FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND THE VEHICLE WAS SOLD BACK TO THE DEALER. THE FAILURE MILEAGE WAS 28,500.

LEXUS RX 450H. 2010. WAS PURCHASED BRAND NEW FROM THE DEALERSHIP. ALL MAINTENANCE WAS PERFORMED AT THE SAME DEALERSHIP THE CAR WAS PURCHASED. SINGLE OWNER. TWENTY MONTHS LATER (AT 34,000 MILES) ALL 4 TIRES ARE NO LONGER GOOD AT THE INNER EDGE. TWO POSSIBILITIES: 1) THE TIRES WERE BAD QUALITY; 2) THE DEALERSHIP FAILED TO BALANCE AND ROTATE THE TIRES. FOR SAFETY, I HAD NO OTHER CHOICE TO CHANGE THEM. I AM VERY DISSATISFIED. *TR

THIS VEHICLE STARTED ACCELERATING ON ITS OWN. WHEN I TRIED TO GET THE VEHICLE TO STOP, THE BRAKES WOULD NOT WORK. NEUTRAL WOULD NOT WORK. DOWN SHIFTING WOULD NOT WORK. THE VEHICLE WOULD ONLY INCREASE IN SPEED. I HAD 3 KIDS IN THE CAR. THE DASH BOARD INDICATOR LIGHTS LIT UP. ALL OF THEM!! WHEN I FINALLY LOOKED DOWN THE ACCELERATOR PEDAL WAS STUCK. I GRABBED IT WITH BOTH HANDS WHILE DOING OVER 100 MPH AND HEARD A POP! THEN THE VEHICLE SLOWED BUT STILL NOT NEARLY SAFE ENOUGH. I FINALLY MANAGED TO DOWN SHIFT THE CAR AT THAT POINT. AND THEN JAMMED HER INTO PARK FROM ABOUT 30 MPH. THERE WAS SOMETHING SERIOUSLY WRONG WITH THIS CAR. IT WAS NOT FLOOR MATS THAT GOT THAT PEDAL STUCK! I SAW THAT PEDAL! YOU NEED TO LOOK INTO THIS FURTHER. SOMEONE IS GOING TO GET KILLED! I WILL BET THEY ALREADY HAVE. I HAD TO TRADE MY CAR IN BECAUSE LEXUS WOULD NOT EVEN CHECK THE COMPUTER FOR FEAR THEY WOULD BE VALIDATING MY COMPLAINT. NOW I GET A LETTER STATING THEY ARE CHANGING THE ACCELERATOR PEDAL? THERE IS SOMETHING MORE TO THIS AND I THINK YOU SHOULD BE LOOKING FURTHER. THAT IS WHY I AM FILING MY COMPLAINT NOW. THEY SAID I WAS THE ONLY ONE. OBVIOUSLY NOT. I SPENT A LOT OF MONEY TO GET OUT OF THAT CAR. PEOPLE SHOULD NOT HAVE TO. PLEASE LOOK INTO THIS. I BEG YOU. *TR

ON 7/1/2011 AT 10.45PM. I WAS DRIVING MY LEXUS 2010 RX350 EASTBOUND ON THE LIE SERVICE ROAD IN GLEN COVE NY. I WAS TRAVELLING AT 35 TO 45 MPH,WHEN SUDDENLY MY "BRAKE MALFUNCTION LIGHT" STARTED FLASHING ON MY DASHBOARD. I INSTINCTIVELY TAPPED THE BRAKE, AND THE BRAKES DID NOT RESPOND. THEN THE CAR HAD UNINTENDED ACCELERATION,I THEN PRESSED ON THE BRAKES WITH ALL MY MIGHT, TO STOP THIS VEHICLE CAREERING OFF THE ROAD.WITH GODS GRACE I WAS ABLE TO STOP THE CAR BY DOWNSHIFTING GEARS. THIS IS THE FIRST TIME I HAVE EXPERIENCED THIS LIFE THREATENING PROBLEM. SO FAR LEXUS HAVE DISCREDITED THIS EXPERIENCE, BY CLAIMING THE MAT WAS STUCK UNDER THE ACCELERATOR AND OR BRAKE. I STRONGLY AND VEHEMENTLY DISAGREE WITH THEIR EVALUATION AND ANALYSIS. I INTEND TO TAKE THIS MATTER FURTHER WITH LEXUS. *TR

2010 LEXUS RX450H. CONSUMER STATES PROBLEM WITH BRAKING SYSTEM *TGW THE CONSUMER NOTICED AFTER DRIVING THE VEHICLE FOR A FEW MONTHS, THAT IT SOMETIMES SURGED FORWARD A FEW FEET WHILE BRAKING OR WHEN LETTING OFF THE BRAKE. THE DEALER INFORMED THE CONSUMER THE BRAKING SYSTEM WAS TYPICAL OF A HYBRID VEHICLE. THE CONSUMER STATED A COUPLE OF WEEKS LATER, THE VEHICLE SURGED FORWARD AGAIN AS SHE WAS BRAKING. *JB

I WAS DRIVING APPROXIMATELY 30 - 40 MPH ON THE FREEWAY. I WENT TO MAKE A LANE CHANGE, LOOKED OVER MY SHOULDER TO MAKE SURE LANE WAS CLEAR, AS I TURNED BACK, THE CAR IN FRONT OF ME STOPPED. I PUT ON MY BRAKES, THERE WAS NO RESPONSE FROM MY BRAKES, THEY DISENGAGED. MY CAR SURGED FORWARD AND HIT THE CAR IN FRONT OF ME. MY SEATBELT DID NOT HAVE ANY TENSION, THEREFORE, MY BODY HIT THE STEERING WHEEL. NOTHING HAS BEEN DONE. THE ACCIDENT JUST HAPPENED. *TR

THE VEHICLE WAS TOWED TO THE DEALER WHERE THEY INSPECTED THE VEHICLE AND INFORMED THE CONTACT THAT THE ACCELERATOR PEDAL WAS STUCK TO THE FLOOR MAT.

UNINTENDED ACCELERATION WITHOUT ABILITY TO BRAKE WITH MY LEXUS RX 350, AT 2 PM ON SATURDAY MARCH 12TH 2011 WITH 5 PASSENGERS. I WAS DRIVING AT AROUND 30 MPH. THE CHOICE WAS TO CRASH IN THE CAR AHEAD STOPPED AT A RED LIGHT OR GO ON THE SIDE WALK, UP A STEEP MOUNT AND CRASH IN A BRICK WALL. THIS IS WHAT I DID. NOBODY WAS HURT. POLICE WAS CALLED AND THE CAR WAS TOWED. CAR WAS INSPECTED BY TOYOTA, NO CAUSE WAS FOUND, CAR WAS REPAIRED AT A GEICO APPROVED REPAIRED SHOP, AND I AM NOW ASKING THE LEXUS DEALER POHANKA TO ALLOW ME TO RETURN THE CAR AND BREAK MY LEASE. IN GOOD CONSCIENCE ALTHOUGH NO ONE WAS HURT, I AM NOT WILLING TO RISK A MORE SERIOUS ACCIDENT AFTER MY EXPERIENCE. WE WOULD HAVE GOTTEN HURT AT A HIGHER SPEED. THIS WAS MY FIRST EVER CRASH DRIVING 20,000 MILES PER YEAR, DRIVING FOR MORE THAN 35 YEARS. THERE IS NO DOUBT SOMETHING OUTSIDE OF MY CONTROL HAPPENED. *TR

I STARTED THE CAR, BACKED IT UP, PULLED FORWARD TURNING TO THE LEFT TO GO DOWN A DRIVEWAY WHEN THE CAR UNEXPECTEDLY ACCELERATED. I STOMPED ON THE BRAKE BUT THE CAR DID NOT STOP. I FLEW OUT OF THE DRIVEWAY, ACROSS THE STREET AND HIT 3 TREES AND A ROCK BEFORE THE CAR STOPPED. *TR

TL* THE CONTACT OWNS A 2010 LEXUS RX450H. WHILE DRIVING APPROXIMATELY 55 MPH, THE VEHICLE BEGAN TO UNINTENTIONALLY DECELERATE.

SERVICE BRAKES, MARCH 13, 2011 - MANSFIELD MA I PURCHASED MY 2010 LEXUS RX 450H IN DECEMBER 2010. EVER SINCE I BOUGHT IT, I HAVE NOTICED THAT FROM TIME TO TIME, WHEN I PRESS THE BRAKE PEDAL, THE CAR SEEMS TO SURGE FORWARD(!) MOMENTARILY BEFORE IT SLOWS DOWN. THIS HAPPENS MOST FREQUENTLY. IT WILL HAPPEN EVEN IF I AM ONLY COASTING AND NOT TOUCHING THE GAS PEDAL WHEN PRESSING THE BRAKE INITIALLY. IT HAPPENS TO ME AT LEAST ONCE OR TWICE A WEEK. IT IS SOMEWHAT DISTURBING. I HAVE MENTIONED THIS TO MY LEXUS DEALER, BUT THEY HAVE DISMISSED MY CONCERNS BOTH TIMES I BROUGHT IT UP. HAS ANYONE ELSE NOTICED THIS ISSUE? VIEW DETAILS

IN A 2010 LEXUS RX 350 MY GRANDMOTHER WAS A PASSENGER IN WHICH THE VEHICLE WAS AT A STOP WAITING FOR AN APARTMENT COMPLEX SECURITY GATE TO OPEN. THE CAR SUDDENLY ACCELERATED TO SPEEDS ABOVE 60 MPH. THE VEHICLE CRASHED THROUGH TWO APARTMENT COMPLEX SECURITY GATES, WENT AIRBORNE OVER A BUSY STREET AND CAME TO REST AGAINST THE SIDE OF A BUILDING. TO OUR HORROR, MY GRANDMOTHER PERISHED IN THE ACCIDENT. WE ARE AWAITING THE INFORMATION FROM THE BLACK BOX. I HESITATE SO SAY TOO MUCH BECAUSE WE ARE STILL IN THE DECISION MAKING PROCESS OF HOW/IF TO PROCEED REGARDING LITIGATION. DO NOT PURCHASE, DRIVE OR RIDE IN ONE OF THESE VEHICLES. *TR

TL*THE CONTACT OWNS A 2010 LEXUS RX350. WHILE STOPPED, THE VEHICLE SURGED FORWARD AND STOPPED ON ITS OWN. DURING THE FAILURE, THE SLIPPING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER BUT THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE 26,000.

TL*THE CONTACT OWNS A 2010 LEXUS RX350. AFTER CRASHING INTO A SNOW EMBANKMENT THE FRONT BUMPER WAS CRACKED AND LOOSE. NO ONE WAS INJURED. THE VEHICLE WAS DRIVABLE AND WAS NOT TAKEN TO THE DEALER; HOWEVER, WHEN THE DEALER WAS CALLED, THEY INFORMED HER TO BRING THE VEHICLE IN FOR INSPECTION. THE BUMPER COST $900 TO REPAIR. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 29,000.

I AM WRITING TO YOU TO DESCRIBE A VERY DANGEROUS CHARACTERISTIC OF THE LEXUS RX 450H. I AM LUCKY THAT A GUARDRAIL PREVENTED ME FROM GOING OFF A CLIFF AND I AM VERY CONCERNED THAT OTHER DRIVERS WILL NOT BE SO FORTUNATE. WHILE DRIVING DOWN A SLIGHT INCLINE ON AN INCH OF SO OF FRESH SNOW IN INCLINE VILLAGE, NEVADA AT 25 MPH, I FOUND MYSELF OUT OF CONTROL EVEN THOUGH I HAD AT LEAST 200 FEET TO SLOW DOWN FOR A TURN; I HIT A GUARDRAIL AT 15 MPH, CAUSING $20,000 WORTH OF DAMAGE TO MY LEXUS RX 450H. NEEDLESS TO SAY, I TRADED IT THE NEXT DAY FOR AN RX 350H TO AVOID ANOTHER SIMILAR EXPERIENCE. SO HOW DID THE SITUATION I DESCRIBE HAPPEN? WHEN I BRAKED, I QUICKLY NOTICED THAT THE WHEELS WERE LOCKED AND THAT THE STEERING NO LONGER WORKED (I HAVE FORTY YEARS OF EXPERIENCE DRIVING IN SNOW, HAVING BEEN IN SNOW SINCE MY YOUTH IN CANADA) AND I REMOVED MY FOOT FROM THE BRAKE TO REGAIN STEERING CONTROL. UNFORTUNATELY, THE WHEELS REMAINED LOCKED AND I RAN OUT OF TIME. MY LEXUS RX 450H HAD LESS THAN 2,300 MILES AT THE TIME. I ACQUIRED IT WHEN MY LEASE ON MY RX 400H RAN OUT. WHILE I WAS AWARE THAT THE RX 400H LOCKED ITS WHEELS IN SLIPPERY ROAD CONDITIONS (A KNOWN ATTRIBUTE DOCUMENTED IN THE USER MANUAL), I KNEW HOW TO REACT AND NEVER PANICKED WHEN THE WHEELS LOCKED; I SIMPLY REMOVED MY FOOT FROM THE BRAKE AND REGAINED STEERING CONTROL. SO WHAT MAKES THE RX 450H DIFFERENT THAN THE RX 400? A LOOK AT THE POWER GAUGE WHILE DRIVING IDENTIFIES THE DIFFERENCE QUICKLY; IN THE RX 400, THE CHARGING SYSTEM DOES NOT TRY TO CAPTURE ENERGY TO RECHARGE THE BATTERIES EXCEPT WHEN ONE IS TOUCHING THE BRAKE PEDAL, WHILE IN THE RX 450H, THE CHARGING SYSTEM TRIES TO CAPTURE ENERGY AS SOON AS ONE REMOVES HIS/HER FOOT FROM THE GAS PEDAL, NOT WHEN ONE TOUCHES THE BRAKE. FROM AN ENGINEERING PERSPECTIVE, IT MAKES SENSE TO LEVERAGE THE FACT THAT THE DRIVER IS INTENDING TO SLOW AS S/HE HAS REMOVED THEIR FOOT FROM THE GAS PEDAL BUT IT IS A DISASTER WHEN THE ROADWAY IS ICY. *TR

TIRE PRESSURE SENSORS APPEAR TO BE OVERLY SENSITIVE IN LEXUS VEHICLES. I OWN 2009 AND 2010 RX350S AND BOTH HAVE ISSUES WITH FALSE ALARMS, AND I WAS TOLD THAT THE DEALER SEES AT LEAST 20 CARS A DAY WITH FALSE ALARMS AND THEY ARE SELLING NITROGEN INFLATION GAS TO REDUCE THE RATE OF FALSE ALARMS. ALTHOUGH IT'S NOT VERY SERIOUS ISSUE AS FAR AS DIRECT SAFETY IS CONCERNED, IT CAN LEAD INTO THE SITUATION WHERE THE DRIVERS WILL START IGNORING THE WARNING LIGHT THAT CAN CAUSE DANGEROUS CONDITIONS. IF THE EQUIPMENT HAS HIGH FALSE POSITIVE RATES, THE MANUFACTURER SHOULD ADDRESS THE ISSUE, BUT THERE IS NO INDICATION THAT IT'S DOING ONE. *TR

2010 LEXUS 450H WON'T START. WE BOUGHT A NEW 2010 LEXUS 450H ABOUT 3 WEEKS AGO, IT ALREADY HAPPENED TWICE, THE CAR JUST WON'T START. BUT AFTER PUSH POWER ON/OFF FEW TIMES, THE CAR STARTS. FIRST TIME IT HAPPENED ON THE MORNING OF NOV 26, WE ARE READY TO GO FOR A WEEKEND TRIP AT 8AM, FOOT ON THE BRAKE AND PUSH THE POWER, ALL LIGHTS GOES ON(EVEN THE HEADLIGHTS), FAN IS ON TOO, BUT NO READY LIGHT, STOPPED IT AND TRIED FEW TIMES, SAME THING, CALLED LEXUS ROADSIDE SERVICE, SAID WILL SEND SOMEONE TO JUMP IN 60 TO 90 MINUTES, I OPENED THE HOOD AND TRY TO FIND BATTERY TO JUMP MYSELF, TAKE A WHILE TO GET THOSE BLACK PLASTIC COVER OFF, DID NOT FIND THE BATTERY, TRY TO START THE CAR AGAIN, AND IT WORKS, THAT IS ABOUT 30 MINUTES AFTER PROBLEM FIRST OCCUR. DROVE 4 HOURS TO A WEEKEND TRIP, SATURDAY, USED CAR FEW TIMES, EVERYTHING IS FINE, THEN SAME THING HAPPENED ON SUNDAY, START AND STOP FEW TIMES, AND IT WORKS. *TR

I WAS DRIVING MY NEW LEXUS 450H (2,000 MILES) IN A FRESH LIGHT SNOW (1.5 TO 2 INCHES) IN INCLINE VILLAGE NV AT 25 MILES PER HOUR ON A SLIGHT DECLINE WHEN I DEPRESSED THE BRAKE PEDAL TO SLOW DOWN FOR A CURVE A FEW HUNDRED FEET AWAY. IT LOCKED THE WHEELS IMMEDIATELY AND AS A RESULT I HAD NO STEERING CONTROL. GIVEN THAT I HAD ENOUGH TIME TO GET MY FOOT OFF THE BRAKE BEFORE HAVING TO MAKE TURN AHEAD, I REMOVED MY FOOT FROM THE BRAKE (I HAVE BEEN DRIVING IN SNOW MY WHOLE LIFE SINCE I WAS RAISED IN CANADA) AND IT HAD NO EFFECT -- THE WHEELS REMAINED LOCKED AS I GAINED NO CONTROL OF STEERING AND THE VEHICLE CONTINUED TO SLIDE UNTIL IT HIT THE GUARD RAIL ACROSS THE STREET AS I ENTERED THE TURN AT SOME 10 TO 15 MILES AN HOUR. I AM CONVINCED THAT THE PROBLEM LIES IN THE 450H TRYING TO GENERATE POWER WHENEVER THE GAS PEDAL IS NOT DEPRESSED -- THIS IS DIFFERENT THAN MY FORMER LEXUS 400H WHICH ONLY TRIED TO GENERATE POWER WHEN THE BRAKE PEDAL IS DEPRESSED (I KNOW ABOUT THE NEW LOGIC BECAUSE THE POWER GAUGE (THAT SHOWS WHETHER THE BATTERIES ARE CHARGING OR DISCHARGING) SHOWS CHARGING WHENEVER ONE'S FOOT IS TAKEN OFF THE GAS PEDAL ON THE 450H, NOT ON THE 400H). NEEDLESS TO SAY, I IMMEDIATELY WENT TO THE LOCAL LEXUS DEALER AND TRADED THE VEHICLE FOR AN RX350 THAT WILL DRIVE LIKE A NORMAL CAR. I AM ONLY INTERESTED IN HAVING PEOPLE THAT LIVE IN HILLY SNOW CONDITIONS AVOID BUYING THE RX450H AS THEY WILL NECESSARILY HAVE THE SAME EXPERIENCE. I DO NOT HAVE VIN AT THIS TIME AS I AM AT MY SECOND HOME IN CALIFORNIA AT THIS TIME. *TR

TL* THE CONTACT OWNS A 2010 LEXUS RX450H. WHILE DRIVING APPROXIMATELY 25 MPH THE CONTACT DROVE OVER A BUMP IN THE ROAD WHILE DEPRESSING THE BRAKE PEDAL. THE VEHICLE STALLED AND SUDDENLY THE BRAKES DISENGAGED. THE CONTACT STATED THE FAILURE OCCURRED SEVERAL TIMES AND CAUSED A REAR END COLLISION WITH ANOTHER VEHICLE. THERE WERE NO INJURIES AND A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIANS WERE UNABLE TO DIAGNOSE THE FAILURE. THE TECHNICIANS STATED THE REGENERATIVE AND THE HYDRAULIC BRAKING SYSTEM BEGAN TO SWITCH FROM ONE TO THE OTHER AND CAUSED THE HESITATION. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 2,000.

TL*THE CONTACT OWNS A 2010 LEXUS RX350. THE CONTACT WAS DRIVING APPROXIMATELY 45 MPH, AND UNEXPECTEDLY AN INCREASE OF ACCELERATION OCCURRED. THE VEHICLE FAILED TO DECELERATE. THE BRAKE PEDAL WAS APPLIED AND THE VEHICLE BEGAN TO SLOW DOWN TO A COMPLETE STOP. THE VEHICLE WAS IN THE PROCESS OF BEING TOWED TO A DEALER FOR DIAGNOSTIC TESTING. THE FAILURE MILEAGE WAS APPROXIMATELY 3,800. THE VIN WAS UNAVAILABLE.

REAR LIFT GATE ON MY LEXUS RX 350 OPENS BY ITSELF WHILE THE CAR IS MOVING AND IS STATIONARY. THIS HAPPENED 5 SEPARATE TIMES OVER THE SPAN OF 4 MONTHS. DURING ONE OF THE TIMES THE LIFT GATE OPENED AND HIT MY GARAGE AND WAS DAMAGED. LEXUS DEALER EXAMINED THE CAR BUT COULD NOT DETERMINE THE CAUSE OF THE PROBLEM, THOUGH THEY OFFERED TO PAY 50% OF THE COST TO REPAIR DAMAGE TO LIFT GATE. SPOKE WITH LEXUS CORPORATE OFFICE AS TO NEXT STEPS TO RESOLVE THIS MALFUNCTION, THEY STONE WALLED ME AND EVEN WITHDREW THE OFFER TO PAY FOR 50% OF THE DAMAGE CAUSED BY THE MALFUNCTION OF THE LEXUS RX 350 REAR LIFT GATE.

TL*THE CONTACT OWNS A 2010 LEXUS RX350. WHILE DRIVING 5 MPH, THE VEHICLE SUDDENLY ACCELERATED AND CRASHED INTO TWO OTHER VEHICLE WHICH CAUSED A CHAIN REACTION. THERE WERE NO INJURIES. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER FOR BODY REPAIRS. THE CONTACT CALLED THE MANUFACTURER WHO STATED THAT THEY WOULD SEND AN INVESTIGATOR TO INSPECT THE VEHICLE. THE VEHICLE HAD NOT BEEN INSPECTED. THE FAILURE MILEAGE WAS APPROXIMATELY 7,000.

THE ENGINE MAKES A NOISE LIKE A SLOPPY PISTON OR A ROD KNOCKING. THE CAR IS A 2010 LEXUS RX350 WITH 69,000 MILES. WHAT IS INTERESTING HERE IA THE FACT THAT THE ISSUE WAS DISCUSSED WITH THE SERVICE GROUP ON A RECENT CONFRENCE CALL BUT THE STAFF WAS TOLD TO KEEP IT QUIET. IS TOYOTA PLAYING THE GAMES AGAIN? *TR

HEADS-UP DISPLAY SHOWS DIFFERENT SPEED THAN SPEEDOMETER OVER 70MPH. *TR

WE BOUGHT A LEXUS 450H 3 MONTH AGO. ON LAST SATURDAY, WHEN THE CAR HIT CURB AT STARTING SPEED, THE STEER WHEEL TURNS 90 DEGREE. THE LEFT FRONT TIRE HAS ONLY VERY SMALL IMPACT, SOME DUST MARK CAN BE EASILY WIPED OFF. THE CAR IS STILL DRIVABLE, BUT WE ARE AFRAID THAT THIS CAR MAY LOSS CONTROL VERY EASILY, ESPECIALLY WHEN IT IS OFF ROAD ON BUMPY ROAD. DEALER IS STILL TALKING WITH THE FACTORY TO CHECK WHETHER THE FACTORY WARRANTY WILL COVER THE DAMAGE. *TR

PART 23565 C-VEHICLE WOULD NOT MOVE. C-BROKEN RETAINING CLIP HOLDING RIGHT FRONT AXLE TO TRANSMISSION. ALSO FOUND A MISSING BOLT IN BEARING CARRIER. THIS IS A 2010 LEXUS RX 350 I PURCHASED IN FEB. 2010 FOR $44,000 WITH 15,000 MILES ON IT FROM THE FREMONT LEXUS DEALERSHIP IN FREMONT, CA. VERY SCARY! LUCKILY I WAS ONLY TRAVELING ABOUT 10 MILES AN HOUR AT THE TIME. THE TRANSMISSION WOULD NOT MOVE. WAS TOLD OLD PART COULD NOT BE GIVEN TO ME. LEXUS OF CONCORD, CA FIXED IT. FREMONT LEXUS ONLY OFFERED TO BUY BACK FOR $33,000. *TR

I BOUGHT A NEW LEXUS RX 350 IN AUGUST 2010 AND HAD A COLLISION ON THE THIRD DAY DRIVING THE CAR. I WAS AT A PARKING LOT WAITING FOR A PARKING SPACE. THE ENGINE WOULD SHUT DOWN. WHEN I SAW A PARKING SPACE AVAILABLE, I STARTED THE ENGINE BY PRESSING THE ENGINE BUTTON WITHOUT PRESSING THE BRAKE PEDAL (YOU DON'T NEED TO PRESS THE BRAKE WHEN YOU USE A KEY TO START THE ENGINE). I DID NOT KNOW BY DOING THAT, I ONLY STARTED THE RADIO AND AIR CONDITIONING BUT NOT THE ENGINE ITSELF. I THEN PRESSED THE BRAKE PEDAL AND SHIFTED TO THE DRIVING GEAR. AT THAT TIME, ANOTHER CAR WAS PULLING INTO THE PARKING LOT. I WAS GOING TO STOP MY CAR TO WAIT FOR THE OTHER CAR TO PASS BY ME. I PRESSED THE BRAKE BUT THE CAR DID NOT STOP AND KEPT GOING FORWARD BECAUSE THE ROAD IS A LITTLE STEEP. I FELT THAT I HAD NO CONTROL OF THE CAR - BOTH THE BRAKE AND POWER STEERING. MY CAR FINALLY STOPPED AFTER HITTING AN EMBANKMENT IN THE PARKING LOT. THERE WAS DAMAGE TO THE FRONT BUMPER AND SCRATCHES ON THE SIDE. TOTAL DAMAGE IS MORE THAN $2,000. WENT TO THE DEALERSHIP AND WAS TOLD THE RX 350 WAS DESIGNED IN THAT WAY - IF YOU PRESS THE START BUTTON WITHOUT PRESSING THE BRAKE PEDAL, THE ENGINE WON'T START, BUT YOU ARE ABLE TO SHIFT THE GEAR TO DRIVING IF YOU PRESS THE BRAKE AT THIS TIME. IT CAN BE VERY DANGEROUS BECAUSE THE POWER STEERING AND BRAKE WILL NOT WORK PROPERLY IF THE ENGINE IS NOT STARTED. *TR

2010 LEXUS RX 350 - I WAS COMPLETELY BLINDED BY BACKLASH WATER, WHICH CAME DIRECTLY FROM THE FRONT WHEEL-WELL, WHILE DRIVING IN VERY HEAVY RAIN ON FOOTHILLS PARKWAY, BOULDER CO. I UNEXPECTEDLY DROVE THROUGH A FLOODED SECTION OF A HIGHWAY AT ABOUT 30 MPH DURING A VERY HEAVY RAIN STORM. IMMEDIATELY ENTERING THE FLOODED AREA, THE FRONT WINDSHIELD WAS COMPLETELY COVERED BY WATER, AND I WAS COMPLETELY BLINDED. IT LOOKED LIKE I WAS UNDERWATER! RATHER THAN WATER EXPELLING TO THE SIDES OF THE CAR, THE WHEEL-WELL REDIRECTED THE WATER BACK ONTO THE CAR IN A WAIVE LIKE MANNER. THE WINDSHIELD CLEARED AFTER THE VEHICLE SLOWED DOWN TO ABOUT 15/10MPH. I INITIALLY BELIEVED THAT THE WATER CAME FROM THE CAR TO THE RIGHT OF ME. I REALIZED THAT THE WATER CAME FROM MY OWN CAR WHEN I DROVE THE CAR THROUGH ANOTHER FLOODED SECTION OF A STREET AT A SLOWER SPEED. I COULD CLEARLY SEE THAT THE FRONT WHEEL-WELL WAS KICKING WATER BACK ON TO THE HOOD OF THE CAR IN A "WAIVE" LIKE FASHION. WITH A SLIGHT INCREASE IN SPEED, THE RATE OF WATER ON TO THE CAR INCREASED, AND WATER EVENTUALLY COVERED THE HOOD AND THEN THE WINDSHIELD. THE SECTION OF THE HIGHWAY WAS NOT CLOSED, AND OTHER VEHICLES WERE GOING THROUGH THE FLOODED AREA. NO CARS WERE STALLED. THIS WAS THE MOST HELPLESS SITUATION I HAVE EXPERIENCED IN MY 40+ YEARS OF DRIVING! THE CAR WAS A RENTAL LOANER FROM THE DEALER, STEVENSON LEXUS OF LAKEWOOD, COLORADO. *TR

TL* THE CONTACT OWNS A 2010 LEXUS RX450 HYBRID. THE CONTACT WAS DRIVING AT UNKNOWN SPEEDS IN A PARKING LOT WHEN THE VEHICLE ABNORMALLY ACCELERATED. THE BRAKES WOULD NOT ENGAGE DESPITE HER REPEATED ATTEMPTS TO STOP THE VEHICLE. THE VEHICLE PROCEEDED TO ACCELERATE AND THE FRONT PASSENGER TIRE EXPLODED. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER WHERE THE CONTACT WAS AWAITING A DIAGNOSIS OF THE FAILURE. THE MANUFACTURER WOULD NOT PROVIDE ANY ASSISTANCE. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 16,000.

ON 7/29/2010 MY 2010 LEXUS RX 350 EXPERIENCED UNINTENDED EXHILARATION CAUSING A COLLISION WITH A PARKING LOT COLLISION SAFETY POST (METAL PIPE FILLED WITH CONCRETE) CAUSING EXTENSIVE FRONTAL DAMAGE OF THE VEHICLE. THE INCIDENT OCCURRED AT APPROXIMATELY 1245 ON A CLEAR DAY DRY PAVEMENT WITH NO OTHER VEHICLES IN THE PARKING LOT NEAR THE SCENE OF THE COLLISION. THE INCIDENT OCCURRED WHEN I WAS PULLING INTO THE A PARKING SPOT MAKING RIGHT HAND TURN. AS I WAS ENTERING THE PARKING SPOT AT APPROXIMATELY 1/2 WAY I TAPPED THE ACCELERATOR PEDAL TO COMPLETE THE PARKING MANEUVER AND THAT IS WHEN THE CAR LUNGED FORWARD WITH A SPEED INDICATIVE OF HARD ACCELERATION COLLIDING WITH THE POST BEFORE I COULD TAKE ANY ACTION TO SLOW OR STOP THE VEHICLE. THE ACCELERATION DETAILED ABOVE HAS HAPPENED ONCE BEFORE WHEN MY HUSBAND WAS DRIVING THE VEHICLE AND EXPERIENCED SUDDEN ACCELERATION. WE WERE BOTH PUZZLED BY THE EVENT BUT DECIDED TO DISMISS IT SINCE IT OCCURRED DURING THE NATION WIDE MEDIA BLITZ ABOUT TOYOTA VEHICLES UNINTENDED ACCELERATION, AND REALLY DID NOT WANT TO BUY IN INTO MASS HYSTERIA. HIND SIGHT BEING 20/20 MAYBE WE SHOULD HAVE. *TR

10 MONTH OLD 2010 LEXUS RX 350 HAS LOOSE BUMPER ALL THROUGHOUT. POSSIBLE THE VERY BOTTOM GENTLY HIT SOMETHING AND NOW THE ENTIRE BUMPER IS FALLING OFF NOW. BROUGHT IT TO DEALER AND HE SAID IF IT'S HIT IN THE RIGHT SPOT THE PLASTIC BUMPER WILL BE LOOSE, BUT WON'T FALL OFF, HOWEVER IF IMPACT WAS ON ONE SIDE ONLY, WHY IS THE BUMPER COMPLETELY SEPARATED UNDER THE HEADLIGHT ON THE OTHER SIDE OF THE CAR AS WELL AND THE GAP IS INCREASING. I LOOKED ONLINE AND MANY PEOPLE HAVE THIS PROBLEM AND IT'S SPECULATED THAT THE BUMPER WAS PUT ON WITH TOO FEW CLIPS TO HOLD IT IN PLACE. BEWARE, THE 2010 LEXUS RX 350 IS POORLY MADE AS A BUMPER SHOULD NOT COME OFF FROM SOMEONE'S KNEE OR LITTLE SCRATCH. AREN'T CARS SUPPOSED TO BE MADE TO WITHSTAND A LITTLE DINGS WITHOUT COMPROMISING AN ENTIRE BUMPER?! *TR

MODEL YEAR 2010 LEXUS RX 350 HAD A SUDDEN ACCELERATION PROBLEM WHILE TRYING TO PARK IN A PARKING LOT PARKING PLACE IN EDMOND OKLAHOMA. THE CAR SURGED FORWARD RUNNING OVER THE CURB AND REQUIRED SWERVING TO THE RIGHT ONTO A GRASS MEDIAN BETWEEN THE PARKING LOT AND BUSY FAST MOVING STREET. THE CAR THEN TRAVELED APPROXIMATELY 100 FEET AT AN UNCONTROLLABLE SPEED BEFORE SWERVING BACK INTO THE PARKING LOT WHERE THE VEHICLE THEN STOPPED. THE CAR IS ONLY THREE MONTHS OLD AND HAS 2040 MILES. THE LEXUS DEALER SAYS THERE IS NO HISTORY OF SUDDEN ACCELERATION ISSUES WITH THIS YEAR AND MODEL CAR. THE CAR IS NOW AT THE DEALERSHIP AWAITING 7- 14 DAYS FOR A LEXUS FACTORY SPECIALIST TO EXAMINE THE CAR. THIS SUDDEN ACCELERATION ISSUE IS NOT MERE PARTS OR INCONVENIENCE ISSUE. THIS WAS A NEAR DEATH EXPERIENCE AND A POSSIBLE LIFE OR DEATH ISSUE FOR OTHER 2010 LEXUS RX 350 OWNERS. *TR

NAVIGATION SYSTEM DOES NOT IDENTIFY POI'S SUCH AS GAS STATIONS ALONG ROUTE. THIS IS DANGEROUS AS WHEN THE NAV SYSTEM IS USED AS A PRIMARY INFO SOURCE - LOOKING FOR A GAS STATION, ONE CANNOT BE FOUND. LEAVES USER IN A PANIC STATE - WHICH CAN LEAD TO DANGEROUS SITUATIONS. LEXUS - SOLD AN INTEGRATED NAV SYSTEM - WHICH IS SUPPOSED TO BE A REFERENCE WHEN TRAVELING. THIS REFERENCE IS UN-RELIABLE AND SHOULD BE RECALLED FOR A FIX AS A SAFETY ISSUE. DISCUSSED THIS WITH SALES PERSON AT DEALER, ACKNOWLEDGED VERBALLY THAT THE NAV SYSTEM HAS PROBLEMS - NO UPGRADES AVAILABLE. *TR

AS I REVERSE OUT OF MY DRIVEWAY, WHICH IS ON AN INCLINE, ONTO A FLAT MAIN ROADWAY, THE VEHICLE STALLS (WHILE STILL IN REVERSE). THIS HAS HAPPENED MULTIPLE TIMES ON MY 2010 LEXUS RX 350, AS WELL AS PREVIOUSLY ON MY 2008 LEXUS 350. *TR

TL* THE CONTACT OWNS A 2010 LEXUS RX350. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATE SPEEDS OF 55 MPH, THE VEHICLE ABNORMALLY ACCELERATED TO SPEEDS OF 90 MPH. THE CONTACT ALSO STATED THAT THERE WAS SMOKE COMING FROM THE TIRES WHEN HE TRIED TO APPLY THE BRAKES. HE WAS ABLE TO SHIFT THE VEHICLE TO NEUTRAL AND TURN THE IGNITION OFF TO GAIN CONTROL OF THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE DEALER COULD NOT DUPLICATE THE FAILURE. THE APPROXIMATE CURRENT AND FAILURE MILEAGES WERE 4,000.

TL*THE CONTACT OWNS A 2010 LEXUS RX 350. WHILE DRIVING THE VEHICLE AT APPROXIMATELY 50 MPH, THE CONTACT DEPRESSED THE BRAKE PEDAL BUT THE VEHICLE DID NOT SLOW DOWN. AS A RESULT, THE CONTACT CRASHED INTO ANOTHER VEHICLE. THERE WERE NO INJURIES BUT A POLICE REPORT WAS FILED. THE VEHICLE WAS TAKEN TO AN AUTOMOTIVE BODY SHOP BUT NO REPAIRS WERE MADE WHEN THE COMPLAINT WAS FILED. THE VIN WAS UNAVAILABLE. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 5,000.

NAV SYSTEM DOES NOT DISTINGUISH HEIGHT ON HIGHWAYS. THIS IS VERY DANGEROUS ON ELEVATED HIGHWAYS - AS NAV SYSTEM ASKS DRIVER TO TAKE EXITS THAT DON'T EXIST. AS A RESULT WILL CAUSE A DRIVER TO PANIC - LEADING TO AN ACCIDENT SITUATION. NOWHERE IN THE ADVERTISING DOCUMENTATION DOES IT STATE THAT IT CANNOT DISTINGUISH ELEVATED HIGHWAYS AND SIDE ROADS. LEXUS CHARGES A PREMIUM FOR THIS DEVICE AND IT IS A SAFETY CONCERN TO DRIVERS UNAWARE OF ITS FAULTS. MOREOVER, THERE SHOULD BE A WAY FOR CAR COMPANIES TO BE ACCOUNTABLE ON THE QUALITY OF ELECTRONICS THEY DELIVER. A NOTICE TO ALL OWNERS WITH THE NAV SYSTEM SHOULD BE SENT OUT. CAR DEALER ACKNOWLEDGES NAV SYSTEM DEFICIENCY. NO FIX AVAILABLE. SUBSTANDARD PRODUCT FOR A LEXUS AUTOMOBILE. *TR

I WAS DRIVING A 2010 LEXUS RX450H ON A HIGHWAY AT @60 MPH WHEN IT ACCELERATED ON ITS OWN TO @80 MPH WITHIN A FEW SECONDS. IT RESPONDED TO THE BRAKE AND I EXITED THE HIGHWAY. I HAD THE VEHICLE PREVIOUSLY CHECKED BY THE DEALER, RALLYE LEXUS IN GLEN COVE NY, AND THEY SAID THEY WERE NO PROBLEMS. THE DEALER AND FACTORY REP. CHECKED THE VEHICLE AFTER THE INCIDENT AND THEY AGAIN SAID THERE WERE NO PROBLEMS WITH THE CAR. HOWEVER, THE EVENT DID OCCUR AND NOW I WILL NOT DRIVE THE VEHICLE. FORTUNATELY THERE WAS NO ACCIDENT AS A RESULT OF THE MALFUNCTION. *TR

LEXUS HYBRID SUV 2010 RX450H. CAR WAS IN SNOW SETTING AND WHEN I TRIED TO BRAKE ON A LIGHT SNOW SURFACE, THERE WAS NO RESPONSE FROM THE BRAKES AND I ALSO WAS UNABLE TO STEER. I CONTINUED FORWARD UNTIL I REACHED CLEAR PAVEMENT AND WAS THEN ABLE TO BRAKE. THIS HAPPENED 3 TIMES TODAY UNDER THE SAME CONDITIONS. LUCKILY NO CARS WERE COMING OR I WOULD HAVE BEEN HIT BROADSIDE ON A BUSY STREET. *CN

ON THE 2010 LEXUS RX350 THERE IS A DESIGN FLAW WITH THE WIPER/WASHER SYSTEM. WHEN TRAVELING WITH HIGH WINDS OR AT HIGH SPEEDS THE WASHERS DO NOT WORK ON THE UPPER PART OF THE WINDSHIELD, HENCE IT CAN BE DIFFICULT TO SEE. THIS CAN BE A SAFETY ISSUE, ESPECIALLY WHEN CONFRONTED WITH ROAD SPRAY IN COLD CLIMATES. THERE ARE NO ADJUSTMENT THAT CAN BE MADE. IT IS A FIXED NOZZLE. *TR

I LIVE IN ALDIE, VA AND HAVE A NEW LEXUS 2010 RX 450H HYBRID. I HAD AN ACCIDENT ON 01/30/2010 AROUND 11AM. WHAT HAPPENED WAS... I WAS DRIVING AROUND 5 TO 10 MILES SPEED AND TURNED THE VEHICLE TO 90 DEGREES SLOWLY TO GO TO THE SCHOOL. BUT THE VEHICLE WENT 45 DEGREES AND HIT A WOODEN STOP SIGN. I WAS REALLY DRIVING SLOW. I APPLIED THE BRAKE, BUT THE CAR SUDDENLY PICKED SOME SPEED AND HIT THE STOP SIGN. ITS UNUSUAL. THERE MAY BE SOME DEFECT IN THE BRAKES/GAS PEDALS OR WITH THE ABS SYSTEM OR THE ELECTRONICS AROUND IT. I CALLED LEXUS CUSTOMER SERVICE AND FILED A COMPLAINT ABOUT THE VEHICLE. THEY ARE SENDING IT TO THE LEGAL DEPARTMENT. THE ESTIMATED DAMAGE TO MY CAR WAS AROUND $5,550 AND THE CAR IS CURRENTLY AT THE AUTOBODY SHOP FOR REPAIR.

MY 2010 LEXUS RX 350 HAS HAD TWO INCIDENTS OF SUDDEN ACCELARATION IN THE 6 WEEKS I HAVE OWNED THE VEHICLE. ON BOTH OCCASIONS, THE VEHICLE SUDDENLY REVED UP PAST 4 TO 5,000 RPM FOR A FRACTION OF A SECOND AND THEN RETURNED TO NORMAL RPM (2000). REPORTED THE FIRST INCIDENT TO LEXUS. NO ACTION HAS BEEN TAKEN BY LEXUS. *TR

TL*THE CONTACT OWNS A 2010 LEXUS RX458. WHENEVER THE STEERING BASE WAS ADJUSTED AN ITEM COULD FALL BETWEEN THE STEERING BASE AND IT PREVENTED THE CONTACT FROM MAKE A LEFT OR RIGHT TURN. THE CONTACT IS CONCERNED ABOUT THE SAFETY RISK SINCE A PART OF HIS KEY CHAIN WAS CAUGHT IN THE STEERING WHEEL. THE CURRENT AND FAILURE MILEAGES WERE 40.

NAV SYSTEM MANUAL ENTRY IS DISABLED WHEN CAR IS IN MOTION. FORCES USER TO USE VOICE COMMANDS. VOICE RECOGNITION IS POOR - HAS DIFFICULTY IN RECOGNIZING WORDS SUCH AS MONTREAL, OTTAWA. STREET NAMES HAVE TO BE EXACTLY FOR EXAMPLE AVENUE MAIN, IF MAIN IS SAID IT WILL NEVER FIND IT. DOES NOT HAVE THE OPTION OF SELECTING INTERSECTION WHEN DRIVING. ALL THIS MAKE THE NAV SYSTEM A SAFETY HAZARD. DRIVER BECOMES DISTRACTED TRYING TO GET THE ENTRY INTO THE SYSTEM. SLOWS DOWN, DRIFTS IN LANE. THIS IS MORE DANGEROUS THAN ALLOWING THE DRIVER TO ENTER DATA MANUALLY. THERE IS AN AFTER MARKET OVER-RIDE AVAILABLE - WHICH THE SERVICE MANAGER SAYS, IF INSTALLED WILL NOT VOID WARRANTY. BUT FROM A SAFETY PERSPECTIVE, LEXUS SHOULD OFFER A USABLE SYSTEM OR REFUND USERS THEIR MONIES AND DISABLE A DANGEROUS FEATURE. *TR

I WANTED TO ALERT YOU THAT OTHER HYBRID MODELS THAT WERE MANUFACTURED WITH THE SAME BRAKING SYSTEM AS THE PRIUS SUFFER THE SAME ISSUE. I HAVE A 2010 LEXUS 450H RX AND ITS BRAKES DISENGAGE WHEN I AM DRIVING ON BUMPY ROADS AND OVER POT HOLES. I LIVE IN A NORTHEASTERN CITY WITH MANY BUMPS AND MY BRAKES STOP WORKING OFTEN AND AS A RESULT I HAVE TO SLAM THEM ON MUCH MORE QUICKLY. ALTHOUGH I HAVEN'T HAD A CRASH AT THIS POINT, I CAN EASILY SEE RUNNING INTO THE BACK OF A STOPPED CAR IN FRONT OF ME IF MY BRAKES DISENGAGE AT THE WRONG TIME. THIS IS A CONTINUAL ISSUE AND I DON'T HAVE A SPECIFIC DATE BUT GIVEN THE PRIUS RECALL, I AM CONFUSED WHY MY OWN BRAKES HAVE NOT HAD A SIMILAR SOFTWARE FIX AND THE ISSUE SOUND EXACTLY THE SAME. THE DATE BELOW IS NON SPECIFIC. I HAVE HAD THE CAR FROM DEC 2009 UNTIL NOW AND THE ISSUE HAS BEEN CONTINUOUS. THE BRAKES APPEAR TO WORK FINE ON SMOOTH ROADS. *TR

TL* THE CONTACT OWNS A 2010 LEXUS RX 350. WHILE ATTEMPTING TO PARK THE VEHICLE, THE CONTACT STATED THE VEHICLE ABNORMALLY LUNGED FORWARD AND STALLED. THIS WAS NOT THE FIRST OCCURRENCE OF THE FAILURE. THE MANUFACTURER WAS CONTACTED AND ADVISED THEY WERE AWARE OF THE FAILURE BUT HAD NOT DEEMED THE ISSUE AS A SAFETY CONCERN. THERE WERE NO RECALLS FOR THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN AND THE CURRENT MILEAGE WAS 2,450. UPDATED 07/06/10. *LJ THE CONSUMER STATED WHEN GOING FROM REVERSE TO DRIVE ON THE STREET, THE VEHICLE WOULD STALL. UPDATED 09/21/10

THE RX450H IS DOWNRIGHT DANGEROUS. THE 4 WHEEL DRIVE DOES NOT SWITCH "ON DEMAND" AS THE ADVERTISING SAYS. I LIVE IN SNOWY MASSACHUSETTS AND DO NOT NEED PERMANENT 4 WHEEL DRIVE, BUT IT IS ESSENTIAL WHEN THE ROADS ARE FULL OF SNOW OR ICE. I WAS PUZZLED AT FIRST THAT THE 4 WHEEL DRIVE ONLY ACTUATED UNDER 25 MPH. I TESTED IT ON SHARP CORNERS IN THE SNOW: THE BACK SLID OUT; AND ON FASTER, GRADUAL CORNERS: THE CAR SIDE SLIPPED. NEVER DID THE 4 WHEEL DRIVE SWITCH ON AND CORRECT THE SLIDE. I LOOKED IN THE MANUAL FOR THE METHOD TO MANUALLY ACTIVATE 4 WHEEL DRIVE BUT COULDN'T FIND IT. I CONTACTED LEXUS. THEY SAID THAT I SHOULD USE THE SNOW SWITCH. THIS IS A MENU ITEM WHICH ANNOYINGLY MUST BE SWITCHED ON EVERY TIME YOU DRIVE. IT DIDN'T WORK AS IT ONLY CHANGES THE GEAR AND ACCELERATION CHARACTERISTICS LIKE ANY OTHER WINTER/SUMMER SWITCH. THEY ALSO SAID THAT IT SHOULD WORK AT HIGH SPEEDS WHEN MORE POWER IS NEEDED. I TRIED THAT AND FOUND THAT AT 60 MPH IF I ABSOLUTELY FLOORED THE ACCELERATOR ON A STEEP HILL THE 4 WHEEL DRIVE WOULD SWITCH ON BRIEFLY. THAT'S HYBRID TECHNOLOGY BEING USED TO REDUCE CONSUMPTION?! I WENT BACK TO MY DEALER: WHAT WAS I DOING WRONG? AFTER TWO MONTHS OF PHONE TAG WITH THE DEALER AND LEXUS, THE DEALER PROMISED TO PICK UP THE CAR AND TEST IT. AFTER A WEEK OF TELEPHONE CALLS THEY SAID THERE WAS NO POINT IN TESTING THE CAR AS IT WAS WORKING "AS DESIGNED". HOWEVER IT WASN'T WORKING AS ADVERTISED WHICH IS THAT THE 4 WHEEL DRIVE WILL COME ON "AS NEEDED". I'D SAY THAT A BROAD SKID IN SNOW IS "AS NEEDED". LEXUS DOES NOT INTEND TO DO ANYTHING ABOUT THIS COMPLAINT. THEY PUT ME ONTO A "BUSINESS DEVELOPMENT" SPECIALIST WHO TRIED TO UPSELL ME ON A NON-HYBRID 4X4 WHICH HE SAID HAD "A NON SLIP DIFFERENTIAL" AND WOULD THEREFORE HAVE BETTER HANDLING. I CONSIDER IT VERY DANGEROUS THAT A DRIVER THINKS THEY WILL HAVE CONTROL BECAUSE OF LEXUS ADVERTISING AND SALESMAN CLAIMS BUT WILL LIKELY LOOSE CONTROL IN SNOW OR ICE AND CAUSE A SERIOUS ACCIDENT. *TR
