What owners report

  • Owners report sudden unintended acceleration at low speeds, including while parking or entering parking spaces, sometimes tied to floor mat interference.
  • Some describe the throttle sticking on startup, causing the car to lurch unexpectedly out of a garage or driveway.
  • Brake failure required pumping the pedal repeatedly before the car would stop, in one case leading to a crash at an intersection.
  • Side and knee airbags reportedly failed to deploy in a frontal animal-strike crash, while in another incident a knee airbag deployed and caused injury.
  • A strong gasoline and burning-wire odor with excessive heat buildup was reported after parking, consistent with an electrical fire risk.
  • Several engine-related surge or sudden-acceleration events occurred on curves or roads, leading to loss of control.

  3. NHTSA 10V499000Oct 21, 2010Brakes728,544 vehicles

    Service brakes, hydraulic:foundation components:master cylinder

    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.

    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.
