I have a 2009 MDX with about 85k miles. For a while now when I drive locally around 25-30mph and slightly accelerate I hear a rattle/vibration that goes away as soon as I move a little faster. I assume with the 85k miles something has started to come loose. Anyone else experience this?

Try and look to make sure your heat shields are not loose or broken. Also, check your pulleys. I had the same rattle and first it was a heat shield but, it's back and it may be another heat shield but, I am having them check the pulleys as well. Idler, tensioner pulleys.

Put a band clamp on the heat shield. I would bet money that fixes your problem. I had same problem and it fixed mine.

I have a similar problem that sounds like a heat shield rattle. It comes and goes at different speeds / loads. Could it be related to motor mounts being worn out? Where is the heat shield that you put the clamp ?
