Loud noise/clunking while going over minor to moderate bumps and passenger side front brake 'grabs" when applying brake and "jumps when releasing. Have had passenger side wheel bearing replaced under warranty as well as power assisted steering motor under recall. Vehicle is driven very little due to out of state work. I have not had it to the dealer for inspection but plan to do so soon.
