2020 BMW m8 common problems

The most-reported problem areas across all 5 owner complaints filed with NHTSA — and what to check before you buy.

Vehicle Speed Control
Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Engine
Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Forward Collision Avoidance
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
