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. Broken spot weld underneath the vehicle. Trying to catch it early on before it gets worse.

What 1999 BMW M Coupe owners say
Most recent owner complaints, unedited.
Subframe tear, separating of trunk floor from rails.
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. This issue is currently unresolved as the fix will be thousands of dollars. There are numerous documented cases of subframe failures on bmw z3, m roadster and m coupe models. This is obviously a manufacturer defect that has no been addresses by the manufacturer. This presents a serious safety issue.
There is a crash risk as the car's subframe is rapidly tearing and this design flaw could eventually lead to a loss of control leading towards a crash. The car involved is a bmw m coupe 1999.
Rear subframe welds are failing. As a result, the floor is tearing from the subframe. The following website contains descriptions and photos of many examples of this very issue. Http://www.thelargeglass.com/bmw/subframe/.
Differential bracket and subfloor are cracking and tearing apart at the weld seams and spot welds. Could lead to unpredictable handling, especially during regular driving turns/highway speeds (instability, rough shaking, loose chassis knocking).
Separation of floor pan welds appears to be a common problem in an uncommon vehicle. I'm unable to provide a cause, since I am the third owner, and have never driven the car at it's intended limits. To my knowledge, it has never been raced. So far, I have not repaired the problem.
Serious cracking along multiple body seams in the engine compartment in strut tower area and in the rear in the lower subframe area.
Rear differential mount cracks. Subframe separating from the floor of trunk, and trunk being teared out by subframe. Major issue!!!!
Recurring airbag light.
