Service brakes, hydraulic: foundation components: master cylinderReported October 21, 2010 · 728,544 vehicles affected
What is wrong
Toyota is recalling certain model year 2005-2006 avalon, model year 2004-2006 highlander, model year 2004-2006 lexus rx, and model year 2006 lexus gs and is vehicles. Brake fluid containing polymers is used that acts as lubricants for certain brake system components. If replacement brake fluid is used that does not contain such polymers, or that contains only small amounts, a part of the rubber seal located at the rear of the brake master cylinder may become dry, and the seal may curl during movement of the piston. If this occurs, a small amount of brake fluid could slowly leak from the seal into the brake booster.
Risk
A leak of brake fluid could lead to a change in brake pedal feel and overtime a degradation in braking performance increasing the risk of a crash.
Remedy
Dealers will replace the seal with a newly designed one. This service will be performed free of charge. The safety recall began on november 15, 2010. Owners may contact toyota at 1‑800‑331‑4331 and lexus at 1‑800‑255‑3987.

Defect investigations

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.

My vehicle caught fire a few days after being repaired by a licensed repair shop in California.
The repair was performed by: Brodie's Tire & Automotive
Address: 1276 Petaluma Blvd N, Petaluma, CA 94952
Phone: [XXX] After the fire, the repair shop admitted in writing that: • The intake manifold melted after the fire
• The engine became “not repairable”
• The fire occurred shortly after their repair
• They offered to “fix it for free,” which indicates awareness of responsibility The fire caused severe heat damage to the engine compartment, electrical wiring, and surrounding components. The vehicle became unsafe to drive, and the engine can no longer operate. This incident presents a serious safety hazard because the fire happened shortly after a repair that involved components near the engine and fuel system. Improper or unsafe repair work may cause similar fires for other consumers. This incident is already under active investigation by: • California Department of Insurance (CDI) – Complaint #XXX• California Bureau of Automotive Repair (DCA/BAR) – Case No: XXX I am reporting this to the federal safety agency because the fire and melted engine components indicate a dangerous defect tied to improper repair work, which may pose a risk to other drivers.

An AutoZone, Durlast brand brake master cylinder failed in less than one year. The piston in the master cylinder dislodged, preventing proper braking in at least two of the four disc brake calipers. The Duralast master cylinder has been retained for inspection. The safety of the driver, passengers, other motorists and pedestrians were placed at risk due to the malfunction of the shoddily manufactured brake component. Braking distance and stopping efficiency were adversely affected. The problem was confirmed by the automobile repair center. The manufacturer has, so far, failed to contact me about the defective brake component. No warning lamps or messages were associated with the master cylinder failure.

Brake pedal goes soft while holding brakes on at a stop. The car will start to roll forward unless more brake pedal pressure is applied. Brake pedal goes almost to the floor. Pumping the brakes restores pressure. My shop bled the brakes twice and found no air in the system. Bleeding did not correct the issue. They said there is a problem with the master cylinder and it needs to be replaced...
