Every BMW Z4 model year side by side — owner complaints and safety recalls filed with NHTSA, crash-test ratings and EPA fuel economy. Pick a year for the full details.
Owners filed the most NHTSA complaints about the 2005, 2006 and 2007 Z4 — at least double the typical year (1). Check those years' problem areas and recall repairs carefully before buying.
Among model years at least two years old, the 2015, 2023 and 2024 Z4 drew the fewest owner complaints.
