TOYOTA issued a recall on the LX 470 model

On certain vehicles, a snap ring on the steering shaft may disengage when the vehicle experiences an unusually severe impact to the front wheels, such as striking a deep pothole. If the snap ring becomes disengaged and the steering wheel is then repeatedly turned to the locked position, over time the steering shaft may become disconnected, resulting in a sudden loss of steering control. Correction: Dealers will replace the steering shaft snap ring with an updated version.
