Hi guys, a few days ago I started hearing sounds which seem to be coming from under the car. It's a knock sound whenever the car is not smooth, for example when up shifting or down shifting, getting the car rolling in first or turning. I also get this knock sound if I keep the car in first gear and just hit the gas and let off to make the car jerk. To me it sounds like it's coming from the back drivers side but I am not too sure. I have booked an appointment to go into the dealer Wednesday morning. Does anyone have any ideas what this might be? I did not hit anything or go over any bumps/potholes at a high speed. Does Hyundai cover suspension under it's warranty? I've only had the car since the end of August and only have 8200 km's on it.
