Overview

2018 BMW M5

The 2018 BMW M5, codenamed F90, represents a significant leap in performance and technology for the M5 lineage. It pairs a potent 4.4-liter twin-turbo V8 engine with an eight-speed M Steptronic automatic transmission and a sophisticated all-wheel-drive system, delivering supercar-like acceleration. While its performance credentials are undeniable, used buyers must be aware of its early-life technical bulletins and recalls, particularly those affecting the fuel system and engine control software. The absence of owner complaints in NHTSA data is a positive sign, but the concentration of recalls in critical areas warrants careful inspection.

Critical Failure Risk

Recalls indicate potential issues with the fuel tank assembly and fuel pump, including inaccurate fuel gauge readings and potential for engine stall due to software-controlled pump failure. These are critical early-life concerns.

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