Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 Z4.
The 2014 BMW Z4 is a passenger car equipped with an eight-speed automatic transmission (S8) and rated at 22 mpg city, 32 mpg highway, and 26 mpg combined, with its engine calling for 6.9 quarts of 0W-30, 0W-40, or 5W-30 viscosity oil. Within the model's complaint history spanning 2002 through 2023—where 2003 peaked at 414 owner complaints and 2022 dropped to a single complaint—the 2014 records seven total complaints and three recalls, with the top complaint areas being the engine, engine cooling, and electrical system. That places this model year well into the Z4's quieter, more mature reliability phase, far removed from the early-generation spike but not entirely free of cooling and electrical concerns worth monitoring.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The federal record for this generation shows a dramatic stabilization over time, with complaints dropping from a peak of 414 in 2003 to just 10 by 2010, and remaining in the single digits for later years like 2016 (4) and 2019 (5). Although the continuous year-by-year dataset skips the 2014 model, the provided target year metrics indicate just 5 total complaints, positioning it firmly within the generation's mature, low-complaint arc rather than its troubled early years. For the 2014 Z4, these few complaints are scattered across the Engine & Engine Cooling/Electrical System (2), Electrical System/Air Bags (1), Tires (1), and Fuel/Propulsion System (1), with zero fire complaints and only 1 crash complaint reported. The data does not specify a root cause for these isolated issues, but the low volume suggests an absence of systemic, generation-defining failures. Given its placement in the generation's highly reliable later arc and minimal federal complaints, the 2014 BMW Z4 is a strong, low-risk year to buy on the used market.
All 7 complaints on record, top 6 components.
