2014 Acura MDX AWD Long-Term Road Test


There's an odd noise coming from underneath the hood of our MDX, but it's almost too rare and undetectable to do anything about it.

Here is one of the dozens of threads from MDX owners: http://www.mdxers.org/forums/94-new-2014-acura-mdx/66322-direct-injection-engine-unacceptable-noise-level.html
Check the large plastic cowling ( the large plastic piece that covers the front of the compartment ) on the side where the air intake is to see if it's loose. What happens is that air will occasionally enter in between the loose cowling and the grill causing it to vibrate. I've noticed this at all speeds. It would seem that the air intake contributes to the issue as it aspirates. The oscillations will even modulate the incoming air and cause the engine to bog down.
The simple fix is to place felt tape over the 'pins' (for lack of a better term) of the cowling so that they fit more tightly into the holes of the grill. After doing so, I haven't had any problems since...
Hope this was helpful and Good luck!
