Inspection checklist

M5 G90 / G99, 2025 to 2027

Printed October 29, 2026. Tick each item at the viewing, and write down what you find.

Before you go

  • Open recalls. Run the VIN through NHTSA or a BMW dealer and ask for proof every recall was done.
  • History report. Check the title, accidents, owners and mileage record.
  • Service records. Ask for them in advance, ideally from a BMW dealer or specialist.
  • Certified or not. BMW can still certify 2025 to 2027 cars. If this one is certified, ask for the paperwork showing when its cover ends.
  • Independent inspection. Book a pre-purchase inspection with a shop that knows this engine.

Known problems on this car

  • Hybrid drive faults and false warning lights

    Ask a BMW dealer to confirm the software level and scan for stored hybrid and charging faults, drive the car in electric and hybrid modes, and charge it on a Level 2 charger before you buy.

  • Carbon buildup on the intake valves about $1,000 to fix

    Listen for a rough idle and scan for misfire codes, and on higher-mileage cars ask whether the valves have been cleaned.

  • A VIN check for the air conditioning wiring recall.
  • The integrated brake unit recall on a few cars built in July 2024.
