Hi folks. I'm having a noise from my 2016 ecodiesel. I'm at 56000miles. Here's what I've figured out so far for when it happens:

-truck fully warmed up (oil around 200*)
-Engine RPMs at or over 2500rpm
-Throttle down (under load)

It does NOT seem to be speed related (IE, same noise at 3000rpm whether i'm going 10mph or 70mph).

and per my title, it sounds like this thing:
Which means I'm annoyed my truck is acting up, but also laughing....

anyway, I'm guessing it is a boost leak where some seal is expanding and no longer sealing at temperature. anyone else have a similar problem?

 

Still under the powertrain warranty?

 

Yeah. I just like to have an idea of the issue before I drop it off, so I know it will be covered.

Newer info:
it ONLY makes the sound in drive (I held the brake in the driveway, ramped up to 2700rpm, and heard the noise). Does not make it in park (same rpm). wastegate issue?

 

UPDATE: Dealership didn't re-create the noise, but they found a "broken exhaust stud on one of the exhaust flanges" (direct from the voicemail). Covered under powertrain warranty. I'll update if the noise is gone when I get it back.

 

I am having the same problem. It started a couple weeks ago, it will make that typw of noise at 2500 rpm when I am pulling the camper. Especially on slopes. I took it out again and now it starts making noise at about 2000 rpm. I thought it was the tensioner pully or the serpintine belt.
My waranties are over.
Any suggestions?

 

I got the truck back after my last post and it was fixed. So it was a broken bolt on one of the exhaust flanges.

 

Thank You for the update.

 

I am crossing my fingers that its something similar to a bolt. Its at the dealer right now.

 

Dealer just called and told me the exhaust gasket broke and needs replacement. Yes sir.
The exhaust manifold pipe where it connects to the catalitic.

 

My 2016 eco diesel with 103K miles suddenly developed a low RPM noise, sounds like a miss but no noticeable loss of power or vibration.
Very noticeable/ annoying when accelerating from a stop. It sounds like one cylinder is dead or an exhaust leak. Dealer had it for a week but couldn't find a problem " It's not throwing any codes". They checked for exhaust leaks, nothing. Noise increases with RPM, not road speed
EGR valve and cooler replaced several months ago. Any ideas?
