Microsoft said on Thursday it was giving customers free retrofits to a wireless racing wheel with its Xbox 360 video game system after hearing of malfunctions in a wheel component.

The company said it was informed of about 50 incidents worldwide of a malfunction in the Xbox 360 Wireless Racing Wheel, in which a component in the wheel chassis may overheat and release smoke when the AC/DC power supply is used.

More than 230,000 of the wheels are in the field, a spokeswoman for Microsoft said.

There have been no reported incidences of fire, injury or damage resulting from the component failure, Microsoft said. adding that customers should stop using the AC/DC power supply for the wheel until they get their retrofits.

The company said it was notifying relevant regulatory agencies such as the U.S. Consumer Product Safety Commission.
