Living with it
Reliability & ownership notes
- Inspect the individual car's Airmatic or optional Active Body Control system, electronics, corrosion condition, and documented service history; generation reputation is not proof of a fault on every car.
- Match filters, ignition parts, fluids, transmission service parts, and suspension components to the exact engine, drivetrain, chassis number, and build date before ordering.
