my 08 Tiburon makes a loud vibrating sound like a Harley ( an exhaust type noise)
get under the car and look for something with a hole or something that is about to fall off ?!
The car also started having problem starting, I would turn if off run in some place and two min later it would not start, two minutes later it started up fine?
Perhaps you might check the crankshaft sensor.
