Hey all - I'm new to the Mazda world and this forum. Just purchases a 2012 Mazda 5 with 61k miles. Got a really nice price on it and couldn't pass it up. It drives nice, transmission is smooth and ride is smooth. However, I have noticed a whiny noise coming from the passenger side. It's not real loud, but there. And I've noticed it changes pitch when I turn the steering wheel, especially when parked. I had the serpentine belt changed on it last night hoping that would help (the belt was bad). But the noise is still there. Anyone else have this? I'm assuming it's the pump, but not sure if it's serious or just part of the vehicle. Like I said, the noise isn't super loud, it's just there. Thanks for your help!
