- Keeping the 2010 hybrid off this page prevents model-year and high-voltage fitment from being backdated.
Living with it
Reliability & ownership notes
- Inspect Airmatic or Active Body Control operation, electronics, cooling-system condition, and documented service history on the individual car; a generation-level reputation is not evidence that every example has a fault.
- Match filters, fluids, ignition or diesel-service parts, brakes, and transmission service items to the exact engine, drivetrain, build date, and VIN before ordering.
Maintenance & service parts
Keep your 2009 S-Class on the road
