Official summary
15289 - special coverage. On some 2008-2009 model year pontiac g8 vehicles, the boots on the front-lower-control-arms can become rigid in cold weather, which can allow water to enter the joint and corrode the surface of the ball joint. If this condition occurs, a loud metallic rattle can be heard from the front suspension when driving on rough road surfaces. Dealers are to inspect the front lower control arm ball joints for free-play and replace the control arms as required.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
