Buying Tips for the BMW 3 Series (G20)

  • ✓Verify that the starter motor fire risk and IBS (Integrated Braking System) recalls have been completed
  • ✓Check for inner shoulder wear on the rear tyres, as the G20 can be sensitive to rear alignment
  • ✓Listen for wind noise around the A-pillars at motorway speeds, which may require acoustic glass or seal adjustment
  • ✓On 330e PHEV models, verify the charging port door operates smoothly and the electric range is as expected
