Overview

2018 BMW 440i

The 2018 BMW 440i presents a compelling blend of sporty design and potent performance, powered by a 3.0-liter turbocharged inline-six engine. This rear-wheel-drive (or optional all-wheel-drive) coupe or convertible aims for the luxury performance segment. While its driving dynamics are a strong suit, potential buyers should be aware of its reliability record, which leans towards 'Below Average'. A single recall concerning the front seat belts exists, and a high Technical Service Bulletin (TSB) count suggests underlying technical complexities that may not always escalate to formal complaints or recalls. Fuel economy is respectable for its class, achieving an EPA-estimated 23 MPG combined.

Critical Failure Risk

The B58 engine, while generally robust, can be susceptible to cooling system component failures, particularly the water pump and thermostat housing. Leaks can lead to overheating and potential engine damage.

Early detection can help you avoid a $400-$1,200 repair.
