This car always makes a doink noise when you get to about 10 MPH after starting it. You won't hear it again until you turn off the car, and then restart it and put it into drive again. Very very annoying, sounds like someone is rapping on the exhaust pipe with a hammer. It happen all the time. I took it back to the place I bought it, and they had no idea what was wrong, so they sent it to a Volvo dealer and they also did not know what it was all about. It's pretty frustrating that a volvo dealer couldn't figure out what is going on with there own vehicle. If anyone out there has experienced the same noise, please let me know. Thanks
