What 1998 BMW Z3 owners say
Seats
March 2007 driving at 40 MPH and upon stopping at red light seat jolts forward causing foot to slip off of brake and nearly causing accident. This happens constantly now on both driver and passenger seat of 1998 BMW z-3. Upon taking car to shop after shop and dealer I was told it would cost $470.00 a seat to fix. I was also told that this part was determined defective by BMW and changed in the next model after it was discovered. This is a very dangerous situation and these parts should be recalled and replaced to save the public from useless and avoidable accidents.

The vehicle air bag light illuminated. The consumer was informed by the dealer that the problem was due to electrical interference in the wiring harness.

Power to the vehicle ultimatley failed as well as the brakes. Wife able to stop the vehicle using the emergency brakes. Within minutes the motor and accouterments were charred to a crisp. The vehicle was totaled.
Suspension
The BMW E36 Z3 1996-2002 (I have the 1998 1.9) are prone to having a separation of the Rear subframe from the differential causing the drivetrain to hang off the vehicle and/or rip out of the trunk's weak aluminum sheet subframe. BMW Germany has acknowledged the problem for a few individuals over the past decade and a half and kept it on the low for them to not spread it further. BMW North America fails to acknowledge the design flaw during their manufacturing process in the North American Plant during the late 90s. The Spot Welds' quality is subpar and worrisome as this catastrophic failure of the subframe to driveline structure has various ways of presenting it self which chiefly includes popped spot welds in the truck which comes hand in hand with a cracked differential ear bracket. …
I have a 1998 Z3 m roadster and the trunk welds holding the subframe is failing. This is a commonly documented issues. BMW dealers acknowledge the issue but BMW north America will not fix it. This is a welding/manufacturing defect that can lead to the differential and suspension components in the rear to completely separate.
