2017 Volkswagen Golf Alltrack

The vehicle had been making mild clunking noises for some time (at least 2.5 years) during some combinations of turns/bumps. When took to mechanic in January 2020, the sound would not reproduce during test drive, so problem was not diagnosed. Clunking sound became more pronounced over time, until on 8/27/21 while driving a neighborhood road, there was a loud clank, as if some metal part came loose. Then there was very loud clunking, as if a metal part was knocking around loose - more pronounced when turning or going over bumps. Upon inspection by a mechanic later in the day, the sway bar had come loose due to one of the bolts on the driver side sway bar bracket had come out. Both this mechanic and later, the Volkswagen dealer mechanic, said this was very odd, since they normally only see sway bar damage when a car has been in an accident. My car has never been in any kind of accident. Sway bars help ensure a vehicle doesn’t roll too much when handling turns. Aside from safety, sway bars help prevent lopsided wheel alignment and work to maintain an overall better grip on the road. A faulty sway bar puts the vehicle at risk for rolling during turns. My belief is that there was something faulty about the sway bar mounting bracket or bolt which explains the mild clunking I heard prior to deterioration (more frequent clunking) and ultimate failure (on 8/27/21). I have a write up of the inspection and repair from the dealer. I also have photos from the dealer prior to the repair.
