I have a 08 aspen and it has pulled to the right since we got it had it back to dealer said nothing wrong anybody have this before

 

what has the dealer checked?

i have pulling to one side in my rover and it can be a few things that can cause it

are the brakes binding? have they had new pads recently?

are the tyres evenly worn? a quick visual check will satisfy your curiousity! lol

being an 08 plate i would suspect that mechanically everything would be fine for a while, tracking etc...

other than that I would take it back to the dealer if its something you're not happy with. thats what the warranty is for right

hope this helps
