this just started to make this ping noise. took it to Hyundai & they told me it was normal that all these veloster's make it. no I don't think so, my friend has one same year & hers does not. there is a problem and it sounds like something is loose like the fan or near there. I'm taking it back again have them fix this problem. the car runs like sh*t, no get up and go, it hesitates when u step on the gas. need to fix it. I bought this car brand new, not happy with Hyundai who keeps telling me nothing is wrong with it. it's under warranty but they wont fix the problem
