I have a 2013 Elantra GT and I noticed the other days, couple of days, where we had really cold mornings when I started my car I could hear the valves or lifters tick ticking away. Now I know that when its cold it takes a few minutes for the thick oil to warm up but I was surprised at the noise. The car has about 200km and my wife's 2010 Elantra with about 40, 000 km doesn't make any. Anyone else have the same thing ? Should I be concerned ?
