NHTSA Complaint #11475611 — 2021 RAM 1500

While starting to drive forward or backward turning, there is a shutter vibration felt slightly heard. It also has grinding shutter vibration at turn in intersection during the turn. The dealer on the 3 complaint visit replaced a front passenger CV Joint and bearing, upon picking the truck up it did it immediately again. Could not return as it was the service department closing time. There is also vibration grinding around 50 mph and up. Dealer states they can not duplicate issue. This is abnormal and concerns me as in a turn or higher speed, something breaks will put my family's lives and other motorist in danger. Also when using AC defrost vent stays open and will cause dew on the windshield.
