Overview

2024 BMW 840i

The 2024 BMW 840i presents a sophisticated grand tourer option for the discerning used car buyer. It pairs a potent turbocharged inline-six engine with BMW's renowned driving dynamics and a luxurious interior. While its EPA-estimated 24 MPG combined offers reasonable efficiency for its class, potential buyers should be aware of a significant recall concerning the starter assembly, which has seen previous iterations and expansions. This issue, though not reflected in owner complaints, points to a component that requires verification of proper repair.

Critical Failure Risk

A recall addresses a potential starter motor overheat condition due to electrical overload after repeated attempts. This can lead to smoke or fire. While a recall remedy exists, the repeated nature suggests vigilance is warranted.

Early detection can help you avoid a $500-$1,000 repair.
