I think you will find brake squeak to be normal in a lot of new vehicles, has to do with compsition of pad material. Are several fixes, but normalily noise returns. Might not be hesitation if you have auto trans. Is trans looking for proper gear, remember it it has 9 to choose from. Have Trailhawk and sometimes it feels like a bump or hesitation at slow speeds, mechanic in family says, after driving, he feels it is trans finding proper gear. Anoying for sure, but I do like the ride and fuel economy.
