Should the steering lock bar break, the steering wheel would lock and the driver would lose the ability to steer the vehicle, increasing the risk of a crash.

Due to improper casting of the steering lock bar, there is a possibility that a minute crack may develop on the surface of the lock bar. Such a crack may expand over a long period of repeated lock and unlock operations, and eventually the lock bar could break.

What to do: Book this in with a dealer now. It affects a safety system.
