Defect
Toyota is recalling certain model year 2007-2011 Lexus GS350 vehicles manufactured June 19, 2006, through July 12, 2011; and model year 2006-2011 Lexus IS350 vehicles manufactured May 27, 2005, through July 13, 2011; and model year 2010-2011 Lexus IS350c vehicles manufactured November 25, 2009, through July 19, 2011. These vehicles, equipped with the 2GR-FSE engine, use bolts to secure the housing and sprocket of the Variable-Valve Timing (VVT) system gear assembly. These bolts could become loose due to abnormal impacts generated within the gear assembly immediately after a cold start-up.
Safety Risk
The loose bolts could cause the VVT gear housing and sprocket to separate and result in the engine stopping while the vehicle is being driven, increasing the risk of a crash.
Remedy
Toyota will notify owners, and Lexus dealers will replace the VVT unit free of charge. Owners may contact Toyota at 1-800-331-4331.
