Beginning about two month ago, I have been going back to the dealer for drive train related issues. The initial issue was a failed rear hub at around 25,000 miles which was found during an oil change. Next, the main drive shaft (propeller shaft) began making grinding noises as well as a wobble/thumping sound at highway speeds. The grinding sound was resolved but the wobble/thumping continued. The followup for that sound found failed half-shafts (both sides), failed rear differential, and failed transfer case/module. The car was returned to me without all repairs being completed due to lack of parts and "warranty not authorizing additional days of rental" the car then began to give failed parking brake service codes and check air bag system codes which supposedly are related now to a failed on board control module. When the most recent codes (today) were given the car would not shift into gear initially.
