Hi all, 2011 Saab 9-3 XWD, currently 9k miles. Just purchased a month ago. Was previously a dealer loaner vehicle.
I have this noise coming from both sides of the rear when the car is in motion. I am unsure if it is just loud enough to sound like it is coming from both sides or if it is really coming from both sides.
It doesn’t start immediately, only after the car has been driven a bit. The noise is most noticeable between 5 mph and 10 mph. It is definitely a rotational sound (I can notice fluctuations in the noise as the wheel spins). It appears to come from both sides. When the car is in the air and the wheels are spinning their is no noise (according to the shop I have been to, I have not been present when this has been done), so that would mean it only occurs when the wheels are touching the road. It does not change when the brakes are applied but goes away immediately when the car comes to a stop. It occurs no matter which gear the car is in (automatic). It even makes the sound when the car is off but rolling.
I have taken it to the dealership and several other repair shops. They all take apart the brakes and inspect the drive train, but no one can find anything out of the ordinary.
