So my car has been doing it for a while now it groans at low speeds like if your in traffic & its stop & go, it makes a groaning sound from the back of the car & its not the brakes... I come to realize my Aston Martin is very quirky..... Has anyone else noticed there car doing this?

 

Yes, I think it was the rear parking brake (the small calipers on the rear discs). Whenever it did that, I would just pull on the e-brake and released it. It usually fixed it.
