Hi cx30 gang, I purchased a 2021 cx30 turbo after having a cx3 and thought it met my needs and was a good design. The cx30 is a good car but a week ago after having a service for oil and cabin air filter there was a problem with the rear differential. I contacted the dealership and they tested the car and discovered the rear differential was damaged to the point it needed to be completly replaced? There was a loud sound when making a left turn . a cracking noise. The service writer said he thought the right rear wheel was going to come off! As a car mechanic a long time ago i know mechanical things and to me it sounded like a binding CV joint or u joint. I have the car back and so far so good but i've never heard of a low milage new car having a failed rear differential. Any other cx30 owners have a similar problem? thanks.
