Bought my car with 40k miles on it from a Mazda dealership in aurora colorado in 2017. I'm at 106k now and I thought I needed wheel bearings on the front driver side tire. Turns out it's the drive train and a transmission failing. My vehicle hums on the front driver side when I accelerate. This issue began just over 100k miles.
