Servicing follows the Condition Based Service system. It monitors oil quality, brake wear and other factors then signals when work is due, often around every 10 000 miles or 12 months for oil and filter. Fixed checks cover brake fluid every two years and filters at longer intervals. Optional Service Inclusive plans cover routine items for several years.
Safety scores are strong across the generation. Euro NCAP awarded five stars with high adult and child protection. NHTSA gives five stars overall and IIHS rates Good in key crash tests. Standard kit includes front collision warning with brake intervention, lane departure warning, Parking Assistant with sensors and camera, multiple airbags and stability control. Higher packages add adaptive cruise and lane keeping.
Keeping the car is straightforward with the CBS display and My BMW app for service alerts. A three-year unlimited-mileage warranty is standard. Run-flat tyres and electronic systems mean dealer or specialist care is preferred for complex items, but basic fluid and filter work is routine.
