I have had my Tucson in for service 3 times for the same problem in the last 13 months. It seems to be a propeller shaft hanger bearing problem. The parts are on order again, so must wait for another appointment. The service technician was very good listening to my concerns and assured me that some things in vehicles are a mystery as to why they don't work properly. Hopefully this next service with a new part will correct this issue. I really like my 2017 Tucson and want to keep it.
