2006 G35 Coupe pulls to the right -- aligned several times!

[RustyK]

I bought my G35 coupe about a year ago. Just after I drove it a couple of weeks, it started pulling to the right. I took it to the dealer, and they aligned it and said they had to order a special part for the alignment. It drove straight for about a month -- then started to the right again. I even took it to an alignment shop to make sure ... it drove straight for about a week, then started the same thing. I took it BACK to the dealer, they aligned it again, and you can guess the outcome after about a week.

What in the world is going on with this? I've owned a number of cars in my life, and I know a pull when it's occuring. They are trying to suggest that it might be a tire pull, but why wouldn't that happen all the time, even after alignment? Everytime I take it back, it's out of alignment -- and I am NOT driving on bumpy or poor roads. I basically drive to work and back most of the time.

Suggestions? I read the bulletin someone posted. I'm going to print that and take it to the dealer, but at this point, I'm baffled and frustrated. Otherwise, it's a Dream car!

bad shock maybe?low tire?

I've had this happen with a Mazda that I bought years ago, for me it ended up being mis matched tires. I didn't notice it until I did a tire rotation. Check to make sure all of your tires are the same, and check how much tread is left on each tire. The left and right front tires should be about the same and the rear should have about the same amount of tread left.

tire pressure, matching tires, bad suspension part...could be many things

Thanks, all. It's going back to the shop tomorrow. Tire pressure, etc. all have been checked many times. Something mechanical is wrong.
