Overview

2025 BMW 840i

The 2025 BMW 840i offers a blend of performance and luxury, aiming for the discerning buyer seeking a sophisticated coupe. Its 3.0-liter, 6-cylinder engine paired with an 8-speed automatic transmission delivers a refined driving experience, while the rear-wheel-drive setup prioritizes engagement. Fuel economy is respectable for its class, achieving a combined 24 MPG. However, potential buyers should be aware of a single, but repeat, recall concerning the starter assembly, which introduces some uncertainty into its long-term dependability.

Critical Failure Risk

A recall addresses a potential starter motor overheat condition due to electrical overload, particularly after repeated attempts to start the engine. This issue can lead to vehicle disablement.

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