I have noticed when my '09 Max hits bumps (ie: manholes, potholes, speed bumps, road cracks, etc) I hear a quick "air sound". Hard to explain but sounds like a "Pfffft".. short a brief from each shock/strut or something.. maybe its the tight suspension and normal.. not sure.. anyone else have this? -Ron

 

I have noticed it also, it isn't all the time though. I never thought much about it until now. Twice I have heard a crunch sound, kind of like I am scraping something underneath but I know I am not......

 

The air noise is coming from the shocks compressing. Completely normal IMO.

 

This happened to my 2012 at 7k miles. It was a front sturt recall? dont know if its only for the 12' but just thought I would mention it

I have this as well.
It seems normal enough when you consider how shock absorbers work.
Crunch sound, I have not heard, so I am unsure if this is normal or not.

 

I had a noise coming from my passenger front strut. At first I thought it was the ABS self check, but the noise happened everytime i took off and hit any type of bump/dip/imperfection in the road.

Here is what fixed the issue.

I had the following TSB applied: NTB10-020
