I have a horrible squeaking noise from my seat every time i go over a speed bump or a bumpy road, I am a light guy so i know its not me buts so irritating. Would this be covered under warranty?

Also I have noticed quite loud noises from what i think is my front pipe when i am doing mid range cruising then it seems to disapear when i am in the higher gears, its really gettin on my nerves, this is on a 2.2 directn and it sounds like a humming noise. Thought it was just me but the mrs mentioned it too.

No problems on my deisel exclusiv though.
