Drive Train, September 4, 2013
RepairPal Expert Overview
Our Quick Take:
The engine could stall while driving due to an internal engine failure.
What Should You Do?
As of this writing Toyota has not released a notification schedule for this recall. If don't receive notification and you feel you should, please contact your dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call.
Many modern engines use a computer controlled mechanical system known as Variable-Valve Timing (VVT) to adjust engine valve timing based on operating conditions. Vehicles equipped with a V-6 engine and VVT are being recalled because bolts securing components of the VVT system could become loose due to normal impacts generated immediately after starting the engine when cold. The loose bolts could cause the VVT gear housing and sprocket to separate. This would cause the engine to stop while the vehicle is being driven, increasing the risk of a crash. Lexus dealers will replace the VVT unit on affected engines to correct this concern.

Potential Number of Units Affected:
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.
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.
Toyota will notify owners, and Lexus dealers will replace the VVT unit free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Toyota at 1-800-331-4331.
