2013, Veloster.( not turbo ). Rattling from engine compartment cant tell if its internal. oil is changed regularly, oil pressure is good. seems to quieten a little when A/C is turned off but doesn't quit. Car has 65,000 miles on it. Any ideas what the rattling is?

 

The way to find out is to listen carefully. The tool you want is a mechanic's stethoscope. At this point it could be literally anything.

Other people have had the same complaint and it turned out to be a heat shield or a fuel line loose https://www.velosterturbo.org/forum/...-anyone-2.html

Some people are saying they had transmissions replaced for a rattling noise https://www.hyundaiaftermarket.org/f...-rattle-83879/
