One problem related to body has been reported for the 2008 BMW 528. The most recently reported issues are listed below.
When driving last week, we heard heavy clunking sounds. We took the car to a mechanic to investigate the noise, and he identified the the frame sway bar mount had sheered off where the sway bar to frame mount is. The mechanic asked if the car had been in an accident. We bought it used in 2012, and there was no report of an accident. Since we have had it, we haven't had an accident either.
