Who has this buzz in their 15-17 GT?

gqneon · Jan 4, 2018

I've owned 2 2015 GT's (one manual PP and now this convertible auto) and they both had this sound from the factory. I'm wondering if it's normal and if it can be eliminated. I made a quick clip next to a fence - but if you've ever heard a buzzing or metallic rattling sitting in a drive through like this post up for me and especially let me know if you know what it is or how to address it.

I think it's causing me some false knock but I have never been able to track it down.

Happens at idle and low rpm low load, or at least that's when I notice it. You first hear it about 4 seconds in. It was easier to hear on my phone than my pc speakers for some reason.

If you still have the factory exhaust clamp underneath the driver's seat, make sure it's really tight.

I think I hear it, and it reminds me of this thread I started a while back about my noise: https://www.mustang6g.com/forums/showthread.php?t=85593

This is what my car sounds like from just behind the driver's side front wheel.

Drives me bonkers and I want to fix it so bad.

Ya maybe an exhaust leak.

I’ve been under the car and nothing is loose that I can tell. Are you referring to the clamp from the factory cat to midpipe, or the sleeve type clamp at the resonator ?

Yea that's what he's referring to. I don't think it's that though. I think it's a similar noise to what alot of us had. I don't think anyone ever got Ford to acknowledge the problem except for one guy who had his engine taken apart by the dealer who found engine damage from parts contacting each other.

That's one buzz my car doesn't have (yet). Shh! Don't give it any ideas!

gqneon · Jan 5, 2018

lol thanks guys, it’s still a mystery to me. Guess I better start saving for that forged longblock and 6R80 build with a converter, just in case...

After which the rattle will return :frusty:

I had something similar once, it was a small rock caught behind a heat shield and the harmonics at take off (mostly) and idle would make it vibrate.

You could try getting underneath and banging lightly in different places with a rubber mallet, sometimes the vibrations this sets up are enough to trigger it.

Worth a look. It's only apparent at idle, but it has that metallic scraping sound.

I have had the stupid rattling buzz on two 2015 GT’s in a row. I’ve tried like hell to find it, and today I stumbled on it by accident when I had it on a drive on lift. For some reason when it’s on jackstands or frame lift it doesn’t duplicate this sound. But when the vehicle is loaded on the tires it rattled his ass off. It is the passenger side flex joint between the stock manifolds/cat to the resonator ... headers next week and problem solved. Holy shit. So happy to finally find it and have been able to duplicate it for once !

Congrats! Its so awesome to finally find the source of weird noises coming from your car! I wish i found the source of mine but so far no luck. :cheers:

Now if the whole car wasn’t a rattletrap I’d be good... one thing at a time.

Hey man was it this sound?

I've had this sound from the right side behind the front tire for the longest time. You can hear it starting at 6 second mark. I took it to the dealer and they couldn't find anything.

That sounds like the BBQ tick.

Who has this buzz in their 15-17 GT?
