When I start up my engine I hear a noise at the end after fully started. It's like a "rrannt" sound at the end.

Also- I have noticed a slight vibration in the gas pedal and when I take certain right handed curves, the vibration is stronger. What's going on with this car? My local volvo dealership is no good IMO. I went back with them to garage to show them the engine noise and wouldn't you know it, my car wouldn't make the sound! They also took it for a test drive and felt nothing unusual. IMO, I am female and they prob think I'm clueless. I also have trouble with the anti-skid device warning coming on. My car had a large vibration one morning when I pulled out from drive way and I thougth my right front tire was coming off. At that point my anti-skid device light came one. I came to a stop and then my car drove off fine. So scary.
