“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.”
NHTSA complaint #10075125, filed 2004-06, 71,100 miles“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).”
NHTSA complaint #10091272, filed 2004-09, 26,456 miles“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.”
NHTSA complaint #10166970, filed 2006-08, 76,000 miles“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. …”
