Picked up vehicle, told the noise was gone all quiet...have to take it back because the rattling noise is still there. I hear it starting out most of the time, i.e., accelerate hear grinding rattling from the front. Maybe it stops at higher speeds & cant hear it?(The service place knew this but said noise was actually from the rear) Good reviews on the place but feel totally lied to right now...after $900. It's so loud I don't feel safe driving..any ideas??
