I went to service center several times, but they couldn't fix these. when i am driving my car slowly under 10 mph, there is noise from front wheels everyday, it is loud. i can hear a continuing sound when i turn my car to left or right on road. when i am driving my car on local road, there is noise from gear-knob button(shift-knob button). i found my car doesn't have door-lock with key. when i lock the front door, other doors are not lock together. but the manual doesn't say like that. *tr
