Trims
NHTSA's VIN data lists these trims for the 2025 Z4. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Problems owners report
Owners have filed 1 complaint with NHTSA about the 2025 Z4. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.
| Part | Complaints | Crashes | Fires | Injuries |
|---|---|---|---|---|
| Engine | 1 | 0 | 0 | 0 |
Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
Recalls
NHTSA lists no recalls for the 2025 Z4. NHTSA's recall lookup checks a specific VIN.
