Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 Z4.
The 2025 BMW Z4 pairs an eight-speed automatic (S8) with EPA fuel-economy ratings of 23 mpg city, 29 mpg highway, and 25 mpg combined, giving the current model year a familiar efficiency profile. In reliability tracking, it has drawn six owner complaints so far, led by Service Brakes and Forward Collision Avoidance issues, and has been subject to two recalls. Set against a model-line complaint history that spans 2002 through 2023 and ranges from a peak of 414 complaints in 2003 to a single complaint in 2022, the 2025 figure sits near the lower end of that spectrum, pointing to a comparatively uneventful early record.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The federal record shows no complaint, recall, investigation, or TSB counts for the 2025 model year, so its reliability must be inferred from the limited 2025‑specific data supplied. In 2025 the vehicle logged one complaint each in the areas of service brakes/forward‑collision avoidance, suspension, steering/wheels/unknown or other, and steering/lane‑departure, along with three crash‑related complaints and zero fire complaints. By contrast, the immediately preceding years (2021‑2023) reported zero to one total complaints per year and no crash complaints, indicating a slight uptick in reported issues for 2025. Recall information for 2025 is absent from the provided year‑by‑year record, so any potential recall campaigns cannot be assessed from this data. Consequently, while the 2025 Z4 does not exhibit widespread problems, the modest increase in complaint areas and crash reports suggests buyers should verify any outstanding recalls or service bulletins before purchase.
