I WAS DRIVING ON A COUNTRY ROAD AND NOTICED A/C WAS ACTING ODD, THEN TEMP GAUGE WENT TO BOTTOM OF DIAL. I COULDN'T STOP ON THIS ROAD. I WAS TRYING TO GET TO GRANDDAUGHTER'S HOUSE. I STOPPED AT LIGHT AND COULDN'T START IT. I CALLED AAA AND CAR WAS TRANSPORTED TO LEXUS DEALER WHO TESTED CAR AND SAID ENGINE FAILED. THERE WERE 122000 MILES WHEN TESTED AT DEALER. THE CAR HAS BEEN DEALER SERVICED THE ENTIRE TIME. IT WAS SERVICED AT 120,000 AND ALL SYSTEMS OK. I'VE HAD AN 80 DATSUN THAT LASTED 250,000 MILES. THE DEALER SAID THAT USED ENGINE $8500. I EXPECTED MUCH BETTER FROM LEXUS. READING SOME NHTSA REPORTS THERE SEEM TO BE A RASH OF OIL LINES FAILING. THERE WAS NO WATER HOSE PROBLEM ACCORDING TO DEALER CHECKING IT

1. WIFE BOUGHT CAR ON AUGUST 31, 2016 FROM DEALER IN TACOMA, WA (WITH 90,900 MILES ON IT) WITH A WARRANTY SERVICE CONTRACT WITH IT. 2. SHE TAKES IT TO A LEXUS SERVICE DEALER IN WASHINGTON AT 95,377 MILES ON JULY 13, 2017 TO HAVE THE OIL AND OIL FILTER CHANGE (NOTE: OIL COOLER HOSE IS RIGHT BY THE OIL FILTER). THEY CHANGE THE OIL AND OIL FILTER, AND MENTION OTHER THINGS ABOUT THE CAR, BUT NOTHING ABOUT OIL COOLER HOSE.) 3. BECAUSE WARRANTY SERVICE CONTRACT IS BEST FOR PEOPLE WHO PUT A LOT OF MILES ON A SHE DROP THE WARRANTY SERVICE CONTRACT IN SEPTEMBER 2017 ABOUT, APPLIED THE REFUND TO AMOUNT OWING ON CAR. 4. ON JUNE 23, 2018 (AT 99850 MILES) THE (ORIGINAL MANUFACTURER) OIL COOLER HOSE LEAK OIL A-LOT, IN ABOUT 1/2 A MILE ALL THE OIL (6 QTRS +) WAS OUT OF THE ENGINE MAYBE, SHE DID NOT NOTICE THE LEAK UNTIL 3 + MILES OF RUNNING THE CAR, (NO LIGHT CAME ON THE DASH). 5. SO READ THAT IN MARCH 2010 TOYOTA HAD THEIR CAR ENGINES WITH YEAR 2007 HAD THE DEALER REPLACE THE OIL COOL HOSE (PART OF THE HOSE WAS RUBBER-AND WAS KNOWN TO LEAK, THE OIL COOL HOSE NOW IS ALL METAL) AND THE CAR I'M REFERRING HERE (2007 LEXUS RX 350) WAS PART OF THE REPLACEMENT TO. ALSO NOTICE THAT THE OWNER OF THE VEHICLE AT THE TIME HAD UNTIL MARCH 2013 TO HAVE IT DONE. AND I GUESS THE OWNER AT THE TIME, NEVER HAD THE ORIGINAL OIL COOLER HOSE (PART RUBBER) REPLACED. 6. SO MY QUESTION HERE IS DOES THE LEXUS DEALER (ON 7/13/2017 WHO CHANGE THE OIL) HAVE ANY OBLIGATION TO INFORM HER THAT SHE HAS A OIL COOLER HOSE THAT IS KNOWN TO LEAK (ORIGINAL ONE ON CAR THAT WAS PART RUBBER)?? 7. I HAVE ATTACHED THE ORIGINAL OIL COOLER HOSE PICTURE (THAT WAS ON THE CAR) TO THIS COMPLAINT. THANKS, FOR YOUR TIME

ON FRIDAY SEPTEMBER 29 2017 MY WIFE WAS DRIVING HER 2007 RX 350 AND SHE NOTICED A LINE OF OIL LEADING TO HER VEHICLE AS IT WAS BACKED INTO A PARKING SPACE. AFTER CHECKING THE OIL SHE NOTICED THE VEHICLE HAD LOST 4 QUARTS OF OIL. UPON INVESTIGATING FURTHER IT WAS OBSERVED THAT THE ENGINE LOST THAT AMOUNT OF OIL IN JUST A FEW MILES. WHEN WE DELIVERED THE VEHICLE TO OUR REPAIR SHOP ON OCTOBER 4TH WE WERE TOLD THAT IT WAS THE RUBBER OIL LINE THAT SPRUNG A LEAK. THEY SAID THEY HAVE REPLACED MANY OF THESE AS THEY ARE A DESIGN FLAW FROM LEXUS DIRECTLY. THE NEW PART WAS IMMEDIATELY ORDERED FROM LEXUS AND IS TO BE INSTALLED WHEN IT COMES IN. AFTER ALL OF THIS I HAVE A QUESTION. IF THIS IS SUCH A PROBLEM PART WHICH HAS BEEN NOW ALTERED TO ELIMINATE THE RUBBER PORTION ON THE PART, WHY WOULD I BE CHARGED FOR THIS PART? THIS HAS BEEN A KNOWN PROBLEM FOR QUITE SOME TIME. AS AN OWNER PAST AND PRESENT OF 9 (NINE) TOYOTA/LEXUS VEHICLES I'M VERY CONCERNED ABOUT HOW SOMETHING LIKE THIS SEEMS TO BE ACCEPTED BY TOYOTA MOTOR CORP AS APPARENTLY NO BIG DEAL. HAD MY WIFE NOT NOTICED THE LEAK THE ENGINE WOULD'VE RUN DRY OF OIL AND I'D BE LOOKING AT A BILL FOR A NEW ENGINE. PROBABLY $8,000. DOES ANYONE THERE HAVE AN ANSWER OTHER THAN THE QUALITY OF PARTS AND ENGINEERING AT TMC HAS TAKEN A DOWNWARD TURN. THANK YOU FOR LISTENING.

Official recalls

11V112000 · Vehicle Speed Control:accelerator Pedal

Feb 24, 2011

TOYOTA IS RECALLING CERTAIN MODEL YEAR 2004-2006 HIGHLANDER, HIGHLANDER HYBRID, AND MODEL YEAR 2004-2007 LEXUS RX330, RX350, AND RX400H VEHICLES. IF THE FORWARD RETENTION CLIP USED TO SECURE THE FLOOR CARPET COVER, WHICH IS LOCATED IN FRONT OF THE CENTER CONSOLE, IS NOT INSTALLED PROPERLY THE COVER MAY LEAN TOWARD THE ACCELERATOR PEDAL AND INTERFERE WITH THE ACCELERATOR PEDAL ARM.

Consequence & remedy

Consequence: IF THIS OCCURS, THE ACCELERATOR PEDAL MAY TEMPORARILY BECOME STUCK IN A PARTIALLY DEPRESSED POSITION RATHER THAN RETURN TO THE IDLE POSITION. A STUCK ACCELERATOR PEDAL MAY RESULT IN UNINTENDED AND SUSTAINED VEHICLE SPEEDS AND MAKE IT DIFFICULT TO STOP, INCREASING THE RISK OF A VEHICLE CRASH.

Remedy: DEALERS WILL REPLACE THE FLOOR CARPET COVER WITH A NEWLY DESIGNED ONE FREE OR CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING MARCH 2011. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.

NHTSA investigations

RQ10003 · Unintended And Uncontrolled Acceleration

Opened Feb 16, 2010 · Closed Mar 1, 2011

Status: closed (inferred from source dates) · Electrical System:software; Vehicle Speed Control:accelerator Pedal

On February 16, 2010, NHTSA's Office of Defects Investigation (ODI) opened RQ10-003 to determine whether the scope of prior Toyota recalls relating to potential unintended acceleration were sufficiently broad, including, among others, Toyota recalls 07E-082, 09V-388, 10V-017, and 10V-023.NHTSA also requested information regarding potential electronic causes of unintended acceleration in Toyota and Lexus vehicles.I. Pedal Interference from Floor mats, Carpet Covers and Plastic Pads in Carpets.During the RQ10-003 investigation, ODI reviewed a large volume of documents to assess whether additional vehicles should be recalled.Following the agency's analysis, NHTSA requested that Toyota recall additional vehicles.Toyota complied with the agency's request.The details of these recalls are set forth more fully in Toyota's reports to NHTSA pursuant to 49 CFR Part 573.These recalls are as follows:Recall 11V-112: (1) model year (MY) 2004-2006 Toyota Highlander and Highlander Hybrid; and, (2) MY 2004-2007 Lexus RX330,RX350, and RX400h (hybrid model). The total estimated population under this recall is 769,379 vehicles.This recall remedies potential accelerator pedal entrapment caused by a loose floor carpet cover (trim panel). Recall 11V-113: (1) MY 2003-2009 through 2009 Toyota 4Runner; (2) MY 2006-2010 Toyota RAV4; and, (3) MY 2008-2011 Lexus LX570.The total estimated population under this recall is 1,381,000 vehicles.This recall supplements recall 09V-388 and remedies potential accelerator pedal entrapment by an unsecured floor mat.Recall 11V-115: (1) MY 2006-2007 Lexus GS300 (all wheel drive vehicles); and, (2) MY 2006-2007 Lexus GS350 (all wheel drive vehicles). The total estimated population under this recall is 19,647 vehicles.This recall remedies potential accelerator pedal entrapment caused by inadequate clearance between the pedal linkage and a plastic pad embedded in the vehicle's carpet.II. Potential Electronic Causes of Unintended Acceleration.After NHTSA opened RQ10-003, NHTSA launched a ten-month study of potential electronic causes of unintended acceleration in Toyota vehicles.NHTSA launched the study in the spring of 2010 in light of concerns aired in Congressional hearings.NHTSA enlisted engineers at the National Aeronautics and Space Administration (NASA) with expertise in areas such as computer controlled electronic systems, electromagnetic interference and software integrity to assess whether electronic systems or electromagnetic interference played a role in incidents of unintended acceleration in Toyota vehicles.That study has concluded.Two reports are associated with the study and are available on NHTSA's website.NASA's report is entitled Technical Support to the National Highway Traffic Safety Administration (NHTSA) on the Reported Toyota Motor Corporation (TMC) Unintended Acceleration (UA) Investigation, NESC Assessment No. TI-10-00618 (Jan. 18, 2011).NHTSA's report is entitled Technical Assessment of Toyota Electronic Throttle Control (ETC) Systems (Feb. 2011).Both reports should be read in conjunction with each other. As stated in its report, NASA did not find an electronic cause of large throttle openings that can result in unintended acceleration incidents. NHTSA did not find a vehicle-based cause of unintended acceleration incidents other than the physical pedal interference causes that are being addressed by Toyota's recalls. This RQ is closed.
