Hello. I want to know more first, does it only make noise in motion or all the time?

Hi,
What do you mean it wont start? Will the engine turn over or it wont? Will the engine not fire up when you try to start it.
Let me know and I can give you more information.
Thanks
Jason

Is there somehting wrong with it or did you recently have an oil change done or something?

It's likely the tires. The Bridgestone Turanza OEM tires were specially designed to reduce road noise, which can be an issue. If you're running a different brand of tire, then that may be the cause. Also, if one of the rear tires has an issue (e.g. uneven wear), that may also be the cause. Possible causes of uneven wear include worn rear struts, infrequent rotation, bent wheel, or wheel/tire out of balance. Wheels/tires need to be rebalanced occasionally - at least every 20k miles.

Carefully place a piece of wood (sawed off broom handle) onto the area the noise is coming from, then place your ear onto the other end of wood handle - you'll be able to hear everything that's happening within your engine or component; similar to a stethoscope.
