Engine
If the valve springs break, the engine could fail and stall while the vehicle is being driven, increasing the risk of a crash.
The engine in the vehicles being recalled may have been assembled with valve springs that can break over time. If a valve spring were to break the engine could fail and/or stall unexpectedly, increasing the risk of a crash. Dealers will replace the valve springs in the affected engines to correct this concern.
Toyota will notify owners beginning December 2013. If you 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.
