Engine Performance
The M440i is powered by a robust 3.0-liter inline-six engine, equipped with BMW’s mild-hybrid technology. This engine delivers impressive power and torque, making it a joy to drive. However, while the engine is generally reliable, some owners have reported issues with the fuel injectors and turbochargers. Regular maintenance, including oil changes and inspections, can help mitigate these problems.

Regular inspections and addressing any unusual noises early on can prevent more significant issues down the line.
Other Key Components
When it comes to other components, the electrical system has been a mixed bag. While many owners have not experienced any issues, there are reports of minor electrical gremlins that can crop up, such as malfunctioning sensors or infotainment glitches. Keeping the battery in good condition and ensuring all connections are secure can help avoid these headaches.
In summary, the M440i is a well-engineered vehicle with a solid reputation for reliability, but like any performance car, it requires attentive maintenance.
