I got a 2011 Versa, I've put 30000 miles on it already, believe it or not, it's only 2012, lol. Anyways, I was wondering if I have to bring it in for the 30000 miles service or can I just wait until I've had it for 2 years. I asking for warranty purposes. Most of the driving is highway miles, brakes sound fine and do not squeek at all, I've put nothing but Synthetic in the car since I got it. The intake is new, just wondering if I really needed to spend 400+ dollars at the dealership.
