The 2015 BMW Z4 is a two-seater roadster that continued BMW's legacy of sporty, rear-wheel-drive convertibles. Produced from 2002 to 2016, the Z4 offered a refined driving experience with a retractable hardtop. Key trims included the sDrive28i, sDrive35i, and the range-topping sDrive35is. Its popularity stems from its engaging performance, luxurious interior, and the distinctive long-hood, short-deck styling. This generation, the E89, particularly stood out for its sleek design and the convenience of its folding hardtop.
The Good
The 2015 BMW Z4 excels with exhilarating performance, a sophisticated design that turns heads, and a comfortable, driver-focused cockpit. It offers a rewarding driving experience for enthusiasts, while its retractable hardtop provides versatility for all weather. Reliability is generally good, appealing to both the heart and the head.
The Bad
Owners should be aware of potential issues with the convertible hardtop mechanism, particularly the hydraulic system, and occasional electrical gremlins. Some find the ride can be firm for daily driving, and cargo space is limited, especially with the top down.

What Problems Does the 2015 BMW Z4 Have?
The 2015 BMW Z4, while generally considered a reliable vehicle, does have some reported issues and areas to watch for, particularly as it ages. One of the more common concerns across the E89 generation (which includes 2015) revolves around the retractable hardtop mechanism. The hydraulic pump and lines that operate the roof can develop leaks or fail over time, leading to the top not functioning correctly. This can be an expensive repair. Another area where owners have reported problems is with the electronic power steering system, sometimes experiencing issues that require costly replacement.
The N54 twin-turbo inline-six engine found in the sDrive35i and sDrive35is models, while a powerhouse, is known to be more complex and can sometimes be prone to issues such as failing fuel injectors, ignition coil problems, and turbocharger issues if not meticulously maintained. Early models of the N54 had some common turbocharger wastegate rattle issues, though by 2015, many of these potential problems may have been addressed through updates or previous repairs.
The 2.0L turbocharged inline-four in the sDrive28i is generally more robust and less prone to the more severe issues of the twin-turbo six, though it is not immune to potential problems like oil leaks or turbocharger wear over high mileage. Electrical gremlins are not uncommon in modern BMWs, and the Z4 can experience issues with various sensors, control modules, or infotainment system glitches.
While there are no widespread, model-year-specific recalls that particularly plague the 2015 Z4, it is always advisable to check the National Highway Traffic Safety Administration (NHTSA) website for any open recalls that may apply to a specific VIN. Long-term reliability can be significantly influenced by how well the car was maintained. Due to its performance-oriented nature and often being driven enthusiastically, regular and thorough maintenance, especially on the engine, transmission, and suspension, is crucial for ensuring longevity and avoiding premature wear and tear. Owners who adhere to BMW's recommended maintenance schedule and address minor issues promptly tend to have fewer major problems.

How long will the 2015 BMW Z4 last?
Based on owner data, a well-maintained 2015 BMW Z4 can reasonably be expected to last between 150,000 to 200,000 miles or more. Many owners report enjoying their Z4s for 10 to 15 years. The long-term durability hinges heavily on diligent maintenance. Weaknesses that tend to emerge over time include the aforementioned retractable hardtop mechanism, potential issues with the power steering system, and wear on suspension components due to its sporty nature. The turbocharged engines, while potent, require consistent oil changes and attention to cooling systems to avoid overheating and premature wear. With proactive care, addressing minor leaks or electronic quirks promptly, the Z4 can offer many years of enjoyable ownership, showcasing BMW's commitment to engineering, albeit with an awareness of the potential for higher repair costs on more complex systems.
What Technology & Safety Features are Included?
The 2015 BMW Z4 came equipped with a respectable suite of technology and safety features for its era, with a focus on the driving experience. Standard technology typically included BMW's iDrive infotainment system, controlled via a rotary dial and buttons on the center console. This system managed audio, climate control, and navigation if optioned. A 6-speaker sound system was standard, with options for a premium HiFi system or a Harman Kardon surround sound system. Bluetooth connectivity for hands-free calling and audio streaming was also standard.
Driver-assistance features were more limited compared to modern vehicles. While advanced systems were not common, the Z4 did offer options such as rear parking sensors, a rearview camera, and adaptive xenon headlights for improved nighttime visibility. Cruise control was standard.
Safety features included standard anti-lock disc brakes, stability and traction control, front and side airbags, and a rollover protection system (pop-up bars behind the seats) that deploys in case of a potential rollover.
Optional features that enhanced the Z4's appeal included a hard-drive-based navigation system with real-time traffic information, voice command functionality, heated seats, keyless entry and ignition, and premium leather upholstery. The sDrive35is often came with a more comprehensive list of standard features.
Crash-test ratings for the 2015 BMW Z4 are not as readily available or as comprehensive as for mass-market sedans and SUVs from the same period. However, BMW vehicles generally perform well in safety tests. The Z4's sturdy construction, along with its standard safety equipment and the deployable rollover protection, contributes to its overall safety profile. While specific NHTSA or IIHS ratings might be scarce for this niche sports car, its engineering reflects a commitment to occupant protection.

When new, the 2015 BMW Z4 had a starting MSRP that ranged from approximately $49,000 for the sDrive28i to over $68,000 for the sDrive35is. The current used market prices for a 2015 Z4 typically fall between $20,000 and $35,000, depending heavily on mileage, condition, trim level, and optional features.

Lower mileage examples and the more powerful sDrive35is models tend to hold their value better.
2015 BMW Z4 Cost of Ownership
Owning a 2015 BMW Z4 is generally considered costly. Insurance premiums can be higher due to its sports car classification and the cost of replacement parts. Fuel economy, while not terrible for the sDrive28i, is modest for the more powerful engines, especially when driven spiritedly. Maintenance costs are typically above average, requiring premium fuel and often specialized servicing. Repair costs can be significant, particularly for issues with the complex retractable hardtop, engine components, or electronics.

Final Verdict: Is the 2015 BMW Z4 a Good Convertible?
The 2015 BMW Z4 is ideal for individuals or couples seeking a stylish, sporty convertible that offers both engaging driving dynamics and a luxurious experience. It appeals to those who appreciate the brand's engineering and a refined open-top driving pleasure. It's worth buying, especially on the used market, as it offers a more attainable entry into the premium roadster segment than many competitors. Buying used is highly recommended due to significant depreciation.
When purchasing, prioritize lower mileage examples and thoroughly inspect the retractable hardtop mechanism. The sDrive35i and sDrive35is trims offer more exhilarating performance for enthusiasts, while the sDrive28i provides a more fuel-efficient and potentially less maintenance-intensive entry point. It's best suited as a second car for spirited weekend drives rather than a primary daily driver, particularly in areas with harsh weather, due to its specialized nature and potential maintenance costs.
