Hi everyone! I bought a new 2016 V6 last month. After about 400 miles I started to notice this clunking/knocking sound coming from the front whenever I go over small bumps or uneven road. It's hard to describe but it sounds/feels like something knocking under the car (link to video of it). The weird thing is that it ONLY does it after a cold start and will go away after a few minutes of driving. I'm worried it will get worse once he weather starts to get cooler. I took it to Ford (showed them this video) and they kept it overnight but said they couldn't hear anything and that everything underneath looked good. Any ideas?

***Noise at 0:15, 0:19, 0:31, 0:51 and 1:02***

 

I dunno man, but you will get much better quantity and quality of responses by posting this issue in the 2015+ Mustang section.

For your dealer to hold your car hostage and then give it back later saying they couldn't find anything is just lazy and otherwise unacceptable for a customer who just spent over $30grand on a brand new car. The noise is there, they need to find it and fix it. There is also a Ford customer service rep who is active here, by making your issue visible in the 2015+ section you might be able to get her attention and involvement on this.

 

Thanks! I'll be sure post in that section!

 

Take it to dealer and have them fix it.

 

Kinda sounds like a shock or bushing. If it's a shock, that would explain the sound going away after warm-up. After the fluid warms up it would move with-in the dampers of the shock easier. Not positive on that, but that's where I would start. I had a bad strut on my wife's new Expedition that started with a little kinda clunky sound and 2 weeks later was a full on blown shock. Covered under warranty, but sure was a bit scary the first time I hit a dip after it blew out, the tire went up quick and then just slammed down and you felt through the whole truck. Don't give up on them fixing it. I love Fords, but sometimes you gotta be "that guy" to get service you deserve.
