Hi all.

New here, just purchased a 2013 coupe 2.0, absolutely love it, although I've noticed a slight rattle coming from somewhere underneath the car under heavy acceleration. It's hard to pin point, it sounds like metal on metal vibration.

It's booked into the dealership in a few days for them to have a look at it, but was wondering if anyone else has problem or has heard of it.

Thanks.

I assume the car is stock? I would just avoid boost until you have it checked out

Put your boxing gloves on and go to the dealership. Good luck.

I have the same problem.. I heard it when I'm in reverse.. and only hear it when i'm slowly pulling out... Was still driving the car aggressively today and car drives fine, but I hear the rattle once in a while.

Please let me know what they say this way I know if it's worth mentioning to dealership.

Primary cat hitting against heat shield? Do you feel like its coming from under the center console?

Heard it from around the center console or up by the hood? If you can get under your car I would check to see if one of flanges came loose...I don't even have a gencoupe but I had this problem after I installed a race header, idk why it would rattle more in reverse but it did for me too

What the dealership said......

They said it is a rattle coming from wastegate... And was normal, I asked to try one of the other ones on the lot, and it had the same rattle.

I guess it's just something to live with.... Love the car so it's not a big deal.... It is my first turbo, always had an v6, so I may just not have been used to it.

Anyway now on to some mods... :)

So after "living" with this rattle for a little over a month I have decided I can not longer live with it.

Back to the dealer tomorrow!

I've found myself leaving the car at home, it actually sounds embarrassing to drive.

The dealership have continued to claim it is normal, but to be honest when you pay $30k for a new car a rattle that belongs on a 87 Civic with a loose exhaust is not normal.

Unless this is sorted this will be the last Hyundai this bloke buys.

If anyone has had any luck let everyone know.

I haven't heard anything like this on mine... I would try another dealer... How many miles is on the car?
