Also since you have a 2006 GP, I suggest you look at this in case you have any other issues, http://www.pontiacproblems.com/tsbs/Grand_Prix/2006/. My 06 hasn't given me crap for issues except for the P0053 code which was taken care of. I love my car lol.
Edit: the website I listed, Pontiacproblems.com, shows what has happened to some owners and some is for the GXP V8 model. The issues listed on that site do not reflect on every single 06 GP so don't get discouraged or in other words, it doesn't mean it's going to happen to you.
