2009 max SV with 74k. Notice a low grumble when stopping. Best way to describe the issue is medium braking, when coming to stop under 20mph. It's not the brakes or tires, both are new. I have noticed as the tire/axle makes the rotation it's doing it in the same spot. Another weird thing is it will only do it when it's warmer out (50+) and is worse when humid out. I tried to get it to do it when taking tech out and couldn't get it. He said maybe bad bearing or hub assembly but I have to get it to repeat the issue. It's so annoying bc some days I can have the car do it and it's extremely loud, other times it doesn't do it. Thoughts?

 

Is there a chance your anti-lock brakes are engaging prematurely.... is it coming from all four wheels?

Or, perhaps are the new brakes not worn in and making a noise as they rub against the discs?

 

Negative. It's from only the front end and I had the front end brakes done over a year ago. This isn't a grinding noise more like a low hum/rotating noise. I know it's hard to explain but my guess was ball bearing. It's probably going to be one of those things I have to have the tech hear it, but it's driving me absolutely insane

 

I had the same problem with my brakes. I had new brakes put on and after about 6 months it had the same symptoms as yours. The noise was fixed by cleaning the brakes. Nissan stealership charged me about $120 for the brake service.

 

I replaced a bearing and hub on two different occasions. Sounds I was hearing were more grinding than anything else and it was loud!

 

That's what I think it is. If it was my brakes it would do it all the time; not only In certain conditions
