When purchased CPO, the dealership replaced one tire out of four, causing vibrations to develop after first 1500 miles of driving (front right). Exacerbated by fact that CPO review missed that same wheel was not circular (probably a pothole impact given Boston roads). During the first few long trips, out of balance front tires (and out of true front right) caused strain on camber bolts on the wheel resulting in vibrations between 20-30mph. Rather than make same mistake, camber bolts all around were replaced, wheel trued, tires balanced, and realigned Not really a hardware issue as much as corner cutting. Repaired free of charge, loaner included, and car is marvelous.
