I bought my 2016 Willy's 2 door in October last year and it just clocked over 18,000 miles recently. Lately I have noticed that when i drive next to a wall or another car I can hear an offbeat ticking noise that sounds different than the injector noise, when I listen to it idle through the wheel wells I don't really hear anything that sounds off to me and when I open the hood all you hear is the injectors and everything sounds normal. I have tried listening to other wranglers start up when they are parked near mine at the store or something but I cannot tell. I mostly hear the ticking when the motor has been running for a while and the cooling fan has cycled quite a few times already. Before I take it in to the dealer and start to deal with all of that fun I was just seeing what anyone else might know about this.
