What Problems Does the 2015 BMW 6 Series Have?

Frequently reported problems for the 2015 BMW 6 Series include issues with the electronic systems, such as the iDrive infotainment system freezing or malfunctioning. Oil leaks, particularly from valve cover gaskets and oil filter housing gaskets, are also reported, especially in vehicles with higher mileage. Some owners have experienced issues with the cooling system, including water pump failures.
While recalls specific to the 2015 model year may vary, it's crucial to check the NHTSA (National Highway Traffic Safety Administration) website for any active recalls related to safety or performance.
Long-term reliability concerns primarily revolve around the potential for expensive repairs. The complex nature of the BMW's systems, coupled with the high cost of parts, can make maintenance a significant expense. Preventative maintenance and addressing issues promptly are essential for minimizing long-term reliability risks. Furthermore, the turbochargers on both the inline-6 and V8 engines can be a point of concern at higher mileages. Routine inspections are important to identify potential problems early on.

How long will the 2015 BMW 6 Series last?

With proper maintenance, a 2015 BMW 6 Series can reasonably provide 150,000 to 200,000 miles or 10-15 years of service. Mileage greatly depends on driving habits and adherence to the recommended maintenance schedule. Long-term durability is generally good, but consistent neglect can lead to premature wear and tear on critical components.
Weaknesses over time include potential issues with the electronic systems, oil leaks, and turbocharger health. Regular oil changes, fluid flushes, and inspections are crucial for maximizing longevity and preventing costly repairs. Addressing issues promptly is important to avoid cascading problems.

What Technology & Safety Features are Included?

The 2015 BMW 6 Series comes equipped with a robust suite of built-in technology. The iDrive infotainment system features a high-resolution display, navigation, and integrated apps. Entertainment features include a Harman Kardon sound system, Bluetooth connectivity, and USB ports.
Driver-assistance features include a rearview camera, parking sensors, and adaptive headlights. Optional features include lane departure warning, blind-spot monitoring, adaptive cruise control, and a head-up display. These options significantly enhance safety and convenience.
Safety features include anti-lock brakes, stability control, and a comprehensive airbag system. While specific crash-test ratings for the 2015 BMW 6 Series may vary depending on the body style (coupe, convertible, Gran Coupe), BMW generally prioritizes safety in its vehicle design. The IIHS (Insurance Institute for Highway Safety) and NHTSA are good resources for checking specific ratings. The availability of advanced safety features like collision warning and automatic emergency braking depends on optional packages chosen at the time of purchase.

2015 BMW 6 Series Prices and Market Value

When new, the 2015 BMW 6 Series ranged from approximately $76,000 to over $120,000, depending on the trim level and options. As of late 2023, used market prices typically range from $25,000 to $45,000, depending on condition, mileage, and equipment.
The 6 Series experiences significant depreciation, typical for luxury vehicles. Factors affecting resale value include condition, mileage, maintenance history, and trim level. Models with lower mileage, comprehensive service records, and desirable options (like the M Sport package) command higher prices. Convertibles tend to hold their value slightly better than coupes.

2015 BMW 6 Series Cost of Ownership

The 2015 BMW 6 Series is considered costly to own. Insurance premiums are higher than average due to the vehicle's value and performance capabilities. Fuel costs can be substantial, particularly with the V8 engines. Maintenance and repair costs are also high, as BMW parts and labor are generally expensive. Long-term ownership requires a commitment to preventative maintenance to avoid potentially significant repair bills. While not economical, the driving experience and luxury features may justify the expense for some buyers.
