2009 Toyota RAV4 electrical problems

On October 10, 2012, Toyota initiated a safety recall of approximately 2.5 million U.S. vehicles involving the following models and model years:2007-2009 Camry and Camry Hybrid, 2009 Corolla and Corolla Matrix, 2008 Highlander and Highlander Hybrid, 2007-2009 RAV4, 2008-2009 Scion xB and xD, 2008-2009 Sequoia, 2007-2008 Tundra, 2007-2008 Yaris, and 2009 Pontiac Vibe.See the federal safety agency recall number 12V‑491 for more details, including the affected vehicle manufacture dates for each vehicle model.Note that only early-production 2009 model year vehicles are included in the recall.Toyota and GM dealers will inspect the power window master switch (PWMS) assemblies and apply a specialized grease that inhibits heat build-up.The circuit board in the PWMS may be replaced with a new one if notchy or sticking feeling is observed during the inspection.The failure report summary above shows counts for the vehicles identified at the start of this Engineering Analysis, specifically the approximately 1.4 million vehicles that share an identical PWMS assembly design including, model year 2007-2009 Camry, Camry Hybrid, RAV4, and Yaris built from September 2006 through August 2008, as well as all 2008 Highlander Hybrid.Toyota subsequently identified approximately one million additional vehicles that have a slightly different PWMS design but contain the same defect condition.Note that the totals for complaints and fires shown above may include duplicative reports (between ODI and manufacturer reports).This Engineering Analysis is closed.See attached report for additional information.The ODI reports cited above can be viewed at www-odi.the federal safety agency.dot.gov/owners/Searchreference under the following identification numbers: 10323848, 10360414, 10392622, 10394453, 10411328, 10429983, 10436663, 10446699, 10447416, 10447417, 10447419, 10447444, 10447515, 10447845, 10447947, 10449270, 10450133, 10450568, 10450606, 10450641, 10451821, 10455540, 10455614, 10456353, 10456438, 10457854, 10457955, 10459730, 10460166, 10460691, 10461220, 10462140, 10462200, 10462247, 10462404, 10462705, 10462761, 10464451, 10464769, 10465421, 10466279, 10466667, 10468126, 10468265, 10475230, 10470313, 10470684, 10471551, 10471824, 10472336, 10472910, 10473753, 10473967, 10473969, 10476921, 10477469, 10478563 and 10478657.

ODI has identified certain Toyota vehicles experiencing a higher rate of fire and thermal event incidents among all Toyota vehicles that use the same power window master switch design.They include a total of approximately 1.4 million model year (MY) 2007 through 2009 Camry, Camry Hybrid, RAV4 and Yaris vehicles built from approximately September 2006 through August 2008, as well as all MY 2008 Highlander Hybrid vehicles.This Preliminary Evaluation has been upgraded to an Engineering Analysis (EA12-006) to further study the alleged defect and its consequences.The ODI reports cited above can be viewed at www-odi.the federal safety agency.dot.gov/owners/Searchreference under the following identification numbers: 10461220, 10460691, 10460166, 10459730, 10457955, 10457854, 10456438, 10456353, 10455614, 10455540, 10451821, 10450641, 10450606, 10450568, 10450133, 10449270, 10447947, 10447845, 10447515, 10447444, 10447419, 10447417, 10447416, 10446699, 10436663, 10429983, 10411328, 10407290, 10394453, 10392622, 10360414, 10323848.

On February 16, 2010, the federal safety agency'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.the federal safety agency 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, the federal safety agency 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 the federal safety agency 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 the federal safety agency opened RQ10-003, the federal safety agency launched a ten-month study of potential electronic causes of unintended acceleration in Toyota vehicles.the federal safety agency launched the study in the spring of 2010 in light of concerns aired in Congressional hearings.the federal safety agency 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 the federal safety agency's website.NASA's report is entitled Technical Support to the federal safety agency on the Reported Toyota Motor Corporation (TMC) Unintended Acceleration (UA) Investigation, NESC Assessment No. TI-10-00618 (Jan. 18, 2011).the federal safety agency'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. the federal safety agency 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.
