Maintenance Schedule and Warranty

I have a 2007 Sentra 2.0S. The car has about 30k and 1 year old. Recently I noticed movement against the pedal and the foot rest (left foot). I can feel the pedal shift slightly when I straighted the wheels out from a 90 degree left or right turn. Any idea what that could be? Also does the car maintenance need to be done at the Nissan dealership, or is proof of the check from another mechanic sufficient? I was doing my own maintenance till now, but now I need to take the car in for a checkup to ensure nothing is wrong with the suspension. Any suggestions?

Cheers,

well if you want anything done through warranty it needs to be checked at a nissan dealership and the work is also done by them. That’s if it falls under warranty

I’m assuming you only have basic warranty being 3 year /60k since you’ve been doing your own work the extended warranty plan includes a certain number of ASP (free) oilchanges
