MDX engine knock sound
I put this into the ANSWERS section but it might be more appropriate here.
My 2010 Acura MDX occasionally has a light knocking sounds when apply light acceleration while going 25-40 mph. Quite often I hear a very light metallic sounds best described as a Christmas bell sound. Every now and then I hear a more pronounced knocking sound. It's not as loud as a diesel clack but can definitely can be heard with the radio off.
Wonder if it is indeed engine knock or something else. It sounds like the engine is lugging a bit.
Tried different premium gas but no difference.
Does anyone else hear the fairly consistent low volume Christmas bells metallic jingle?
Does anyone else hear the occasional engine knock?
Thank You

First the car must be fully warmed up.
What sounds like a metallic knocking noise at medium to light acceleration from 0 - 25 mph.
The noise is there in reverse.
Doesn't make the noise in neutral or park.
Doesn't make the noise if the engine has not reached full operating temperature.
I've also encountered several other 2010/2011 mdx owners with this same problem.
