Question about Brake Noise

[uwmcsguy]

Hi All,

I just got a Red 2011 Nissan 370z (auto transmission, brand new with 70 miles), and am pretty happy with it. The only thing I've noticed though is that when I bring the car to a complete halt, and then take my foot off of the brake pedal and let it creep forward, that there is a slight noise that comes from the car brakes at the time when my foot is coming off the pedal.

Kinda like a very small, short groan (if you would even call it that - The term makes it sound worse than what it really is).

It's not a squeeling noise, grinding noise, thumping noise, vibration or anything like that. There are no noises while the vehicle is running, and no noises during normal braking/release while the car is moving. For all intents and purposes, the brakes seem to be working fine as does the rest of the car.

Using Google and researching to see if anyone else has noticed similar behavior, I found a couple of helpful articles. For example:

Groan noise –. It is perfectly normal for some ABS systems to make a groaning noise when
the ABS is activated. On some vehicles equipped with automatic transmissions, a slight groan
may be heard from the brakes just as the vehicle comes to a complete stop or when allowing
the vehicle to creep forward slowly from a stop

Nissan also directly published a technical bulletin on brake systems for all of their cars back in 2004, covering procedures that dealerships should apply in troubleshooting brake problems. It's of course 6-7 years old, but was still very helpful (NTB00-033b)

Groan noise when slightly releasing the brakes after coming to a stop:
• This is sometimes called “creep groan”
• It is a normal condition. No repair or service is necessary

But for anyone else that owns a 370z with an automatic transmission, is this something that's just normal to the vehicle when you take your foot off the pedal?

Guess I'd feel a little better if I knew this was pretty common. Otherwise, I'll likely take it to the dealership at minimum to ask.
