I have been reporting this problem to each of the 3 Hyundai dealerships I have had since I purchased this vehicle. All were dumfounded until I produced videos and complaints from other 2012 Turbo owners. Now I am still waiting for Hyundai to determine if they are going to pay for the problem. I'm told it doesn't do any damage, but when you are in the heat of the summer and our car sounds like it is going to blow up and the only way to stop the noise is to turn off the A/C, place your car in park and then reengage everything, its not pleasant, convenient, or at times feasible.
