RIGHT PASSENGER FRONT ROW WINDOW MOTOR STOPPED WORKING FOR NO APPARENT REASON. THIS WINDOW WAS RARELY USED SO IT WAS VERY SURPRISING. NO LONGER UNDER WARRANTY.COST $345.36 TO FIX. WAS FIXED BECAUSE OF FEAR OF NOT BEING ABLE TO EXIT VEHICLE IN CASE OF A CRASH. TOYOTA SAYS 2004 IS NOT PART OF CURRENT RECALL FOR WINDOW MOTORS BUT DEFINITELY SEEMS LIKE THE RECALL SHOULD BE EXPANDED BECAUSE HAD SAME PROBLEM HAPPEN AGAIN ON THE 2ND ROW PASSENGER SIDE WINDOW MOTOR ON JULY 09. SUDDENLY STOPPED WORKING FOR NO APPARENT REASON AND AGAIN THIS WINDOW BARELY USED. COULD NOT AFFORD TO FIX SO IT IS STUCK IN UP POSITION. HAVE CONTACTED TOYOTA AND HOPING THEY WILL EXPAND RECALL TO 2004 HIGHLANDERS.

INTERMITTENT LOSS OF A/C AND/OR HEAT AND FINALLY TOTAL LOSS OF A/C ON MY 2004 TOYOTA HIGHLANDER. INITIAL FIX WAS TO TIGHTEN THE NUT ON THE TEMPERATURE CONTROL. I FOUND THAT THIS PROBLEM WAS INHERENT AFTER GOING TO THE WEB AND LEARNING OF THE MANY PROBLEMS WITH THE ASSEMBLY AND THE QUICK FIX. ESSENTIALLY THE A/C STOPPED WORKING ENTIRELY. I BROUGHT IT TO MY PRIVATE MECHANIC AND HE FOUND THAT THE CABLE FROM THE TEMPERATURE CONTROL TO THE MOTHER BOARD WAS BROKEN. I INQUIRED HOW THIS COULD HAPPEN AND WAS ADVISED THAT WHEN THE NUT ON THE TEMPERATURE CONTROL CAME LOOSE, THE WHOLE UNIT WAS TURNING WHEN I WAS ADJUSTING THE TEMPERATURE, WHICH CAUSED THE CABLE TO BREAK. THE LACK OF A LOCK WASHER OVER THE FLAT WASHER WAS THE CULPRIT THAT ALLOWED THE NUT TO COME LOOSE. BECAUSE THE CABLE FROM THE MOTHERBOARD TO THE TEMPERATURE CONTROL IS HARD WIRED, THE ENTIRE ASSEMBLY HAD TO BE REPLACED AT A COST OF APPROXITMATELY $950.00. NOTE: I HAVE THE ENTIRE FAULTY ASSEMBLY AT HOME, IN THE EVENT YOU REQUIRE TO SEE IT. *KB

A 2004 TOYOTA HIGHLANDER SIGNAL LIGHT (SAFETY ITEM) IS MALFUNCTIONING AND WHEN I TOOK IT TO TOYOTA DEALER (DARCARS), I WAS TOLD I HAVE TO CHANGE THE NAVIGATION SYSTEM (LUXURY ITEM) WHICH CURRENTLY IS WORKING. I HAVE NO IDEA WHY THEY HAD TO INTEGRATE THESE TWO FUNCTIONS WHEN ONE IS A SAFETY AND THE OTHER ONE IS LUXURY ITEMS. BESIDES, IT COSTS $6000 + LABOR + TAX TO CHANGE THE NAVIGATION SYSTEM. AFTER INTENSIVE SEARCH ON THE INTERNET I FOUND OUT THAT TOYOTA KNOWS ABOUT THE PROBLEM EXCEPT THEY ONLY COVER THE PROBLEM UNDER THE 36,000MILE/3 YEAR WARRANTY. IF THIS WAS A MILEAGE RELATED PROBLEM, I CAN UNDERSTAND EVEN IF TWO NONE RELATED FUNCTIONS ARE INTERLOCKED, BUT THIS HAS NOTHING TO DO WITH MILEAGE AND WE CANNOT DRIVE WITHOUT A SIGNAL LIGHT BUT WE CAN WITHOUT A NAVIGATION SYSTEM. THIS PROBLEM STARTED A MONTH AGO AND I HAVE TRIED TO GET A RESPONSE FROM TOYOTA AND THEY ARE NOT GIVING ME ANY RESPONSE REGARDING THIS MATER. *TR

1RQ10003 · 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.

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.

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.
