Hi all. My father has a 2012 Elantra Limited. He has a strange noise on start up. I told him I think its the Alternator Pulley. As my 13 GS Coupe does it. Usually after sitting for a few days. Its hard to describe the sound. Kind of a Ruring sound. Then goes away. Usually on start up. But today he said it lasted longer.

Thanks all.

My 2011 Elantra had the same ruring sound at start-up a long time ago. I haven't heard it in a while. It probably is the alternator pulley, there have been complaints of them being too tight and causing the sound that you hear. I don't understand how Hyundai missed this, but mine eventually stopped making the sound. (Or I've gotten use to it)

The Alternator has a Clutch in it. Like an AC Compressor. I think it has to do with increasing MPGs.
