So I started having a vibration issue on my 16 V. Thought it was due to the torque converter TSB. Then it started banging under acceleration. Took to the dealer. While on the diagnostic test drive the noise got worse. They pulled over to have a look. 3 bolts fell out from underneath. They flatbed it back to dealership and put it on the rack. Found one bolt left holding in the drive shaft. 4 bolts were sheared off. ????WTF??? No work has ever been performed on the car other then maintenance. Only 24k on the ODO. Anyone else hear of anything like this happening. Glad it didn’t come off on a high speed run.
