What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Rear subframe is beginning to separate from the body of the vehicle, possibly contributor to unsafe and unstable handling. First noticed after having service 2 interval done in 2009, but upon more research online many z3 owners are having this same issue regardless of model or how it's driven.
The 1999 bmw m coupe I own is suffering from a rear subframe failure. The differential mount and rear subframe are becoming disconnected from the frame. Visual inspections have shown the separation. This will lead to the rear differential becoming totally disconnected from the car, leading to a possible accident.
Could lead to unpredictable handling, especially during regular driving turns/highway speeds (instability, rough shaking, loose chassis knocking).
Rear differential mount cracks. Subframe separating from the floor of trunk, and trunk being teared out by subframe. Major issue!!!!
Seat shifts in direction of deceleration (brake) and acceleration (gas). Feels like seat will come off its rails.
When brakes are applied the front seats slide forward approximately one half inch, when brake pressure is released seats slide back into place. Vehicle traveling at 60 mph hit a bump in roadway and the driver's side, closed and locked door unlatched and open enough for the air to rush in and the road could be seen…
