Unintended and Uncontrolled AccelerationOpened February 16, 2010, closed March 1, 2011

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.

Driving along the freeway in winter conditions I used the rear defroster for the back window, this caused the back glass to explode loudly, shattering glass onto belongings, animals and the road behind us. This caused drivers behind us to act evasively and myself as well making a winter driving condition more dangerous, not to mention the spray of glass that reached the back seats of my car with passengers. This has been well documented by other drivers and been acknowledged by Toyota in letters and technician bulletins for replacement of the windows, there are no warning lamps, it just goes from working correctly to exploding.

My rear window shattered after using the defroster. Once I got out of my car after parking it in my job's garage it busted on it's own. I found out that this has happened to many 4th generation 4runner owners but toyota won't recall or extend the warranty for this issue any longer. Now I have to either never use my rear defroster again while living in colorado or risk it shattering again and hurting passengers in my car. I would have never bought the vehicle if I had knowledge of such a dangerous issue.

The rear hatch door handle is deformed and turned into a tar-like mess that covers our fingers whenever we try to open the rear hatch. I have noted numerous other 4-runner owners having the same exact malfunction. Problem is the melted rubber cover which is part of the switch assembly, part #84840-35010. Totally unsat!

Vehicle was parked on shoulder of road, engine running, whilst adjusting the mobile GPS (hence the reason for stopping). At first smoke was coming up around/through center console (between driver's seat and passenger front seat) and then flames. The interior of passenger compartment was totally burned out in spite of prompt response by emergency crew. State farm insurance has naturally been notified although I hardly see why state farm should pay and not toyota. Surely there must have been something wrong with electrical wiring.
