Basic warranty on this car is 4 years / 50,000 miles. Only 40.5% of reported failures happen inside it — the remaining 59.5% come out of the owner's pocket. Powertrain cover (4 years / 50,000 miles) reaches further, but it only covers the engine and transmission, which account for about 12% of the complaints here.
What actually fails — and at what age
On the BMW Z3, the early trouble is Seat Belts and Electrical System — reported at around 3.4 years, so a car still under warranty is the one to check for it. What waits further out is Air Bags at 5.1 years — past every basic warranty, and the bill lands on whoever owns the car then.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Air Bags | 5.1 yrs | 8 | 1 | |
| Seats | 5.6 yrs | — | 1 | |
