My 2017 Guilia TI with sport package started making a loud “thunk” on small road bumps. Sounded like a collapsed shock or a broken sway bar link. The sound got progressively worse, but the sound was always related to road irregularities. Took it to the dealer 10 days ago and they are replacing the rear differential under warranty. The car has always been easy to pitch sideways and break loose the rear. I hope with the “fix”, the driving character doesn’t change cause I’d hate to lose the fun of sliding through a corner.
