I sadly have a problem on my '06 Sonata that is proving very difficult
On cold starts, when the car has been sitting for at least 8 hrs or
so, I will hear a (sometimes faint sometimes louder) metallic grinding
noise coming from under the hood somewhere, possibly near my wheels,
though I'm not sure.
I took it into the Hyundai dealership here, who rather quickly deduced
it was the power-steering pump. Well...It was replaced 48 hrs ago and
I just cold-started it...and the noise is still there.
While I'm totally ignorant on any mechanic stuff not involving the
most basic of 70's era American cars...I suspect some sort of bearing
or belt or chain issue.
Hyundaitech-man...PLEASE HELP ! I have to drive this thing 800 miles
to my wedding in 10 days !
