I have an issue with my 2005 Vibe and it has been like this for awhile. When I hold the steering wheel centre of the vehicle while driving it will pull to the right. Now I have had two wheel alignments done to this vehicle for free. 1st time was at the dealership when the passenger airbag recall was going on and they had a free inspection for Pontiac's at the time. Second time was a month or two ago to get a new wheel stud and some door trim fixed. (i don't know how I got the second one for free but I was glad to have the steering wheel straight for a while)
One of my co-workers (he use to work at Kal-Tire) mentioned that it could be the steering column but I thought I ask you guys and gals for advice before going ahead with any repairs.
