Overview

2020 BMW M850i

The 2020 BMW M850i is a potent grand tourer that blends V8 power with sophisticated luxury. For the used car shopper, this model presents a compelling performance package, but it's not without its complexities. With a robust 4.4-liter V8 engine paired with an 8-speed automatic transmission and all-wheel drive, it delivers exhilarating acceleration. However, a significant number of recalls, particularly concerning safety-critical systems like brakes and airbags, warrant careful consideration. While consumer complaints are notably absent, the recall history suggests potential manufacturing or component issues that demand thorough pre-purchase inspection.

Critical Failure Risk

A critical recall addressed potential separation of the rotor and shaft in the integrated brake system, leading to loss of ABS and braking assistance. This is a safety-critical component requiring immediate attention if any anomalies are detected.

Early detection can help you avoid a $2,500-$4,000 repair.
