I recently purchased a used 2013 Outback with a little over 120000 miles on it. So far I'm loving every part of being a Subaru owner although I have noticed something since driving it off the lot. Whenever I am losing acceleration there is a whining noise that comes from what seems to be the passenger side. I don't notice the noise when my foot is on the gas and I'm up to speed, but when I'm trying to accelerate or let off the gas to slow down the car seems to let out a whine or moaning noise. Any ideas on what could be causing this issue? Thanks so much!
