I ran across this article today http://www.clickondetroit.com/news/21700042/detail.html after reading it I did some research to see if any G6's were affected. Could be possible that your 6 (especially older models) had it's steering column manufactured by JTEKT North America which runs it's automotive division in Wixom, MI. If you read the article I posted you'll notice this was an internal problem that GM is just now fessing up to.
