Hi all. I just purchased a new-to-me 2010 CX-9 GT AWD with 25k miles. After scouring the forums, I'm starting to freak myself out that there might be a transfer case issue, but the symptoms don't really match up with what I'm reading on here. Anyway, when accelerating from a stop, and only in 1st gear, there is sort of a whining or winding-up noise that sounds like it's coming from the front of the car. The sound isn't present in gears above 1st. There is no smell, leaks, or grinding noises. It almost sounds like a turbo to give an idea of the sound, but not quite as high-pitched. Is this normal or is it something I should look further into? Thanks in advance.
