Overview

2020 BMW 540i

The 2020 BMW 540i presents itself as a sophisticated luxury sedan, balancing potent performance with everyday usability. Under the hood, a 3.0-liter, 6-cylinder engine paired with an 8-speed automatic transmission delivers power to the rear wheels. While its EPA-estimated 25 MPG combined is respectable for its class, potential buyers should be aware of six NHTSA recalls issued for this model year. These recalls, though addressed by the manufacturer, point to areas requiring diligent inspection. The absence of owner complaints is a positive sign, but the recall history, especially concerning braking assist and backup camera systems, warrants a thorough pre-purchase examination.

Critical Failure Risk

Multiple recalls have addressed issues with the rearview camera system where the image could be obscured or settings prevent visibility. This can stem from software glitches or, less commonly, hardware failure.

Early detection can help you avoid a $800-$1,500 repair.
