Rust problems, especially on the sunroof area and the tailgate.
Electrical connections and wiring, mainly in the injection and ignition systems, and radiator fans, causing poor running. Inspecting and cleaning them is a real must!
ABS light comes on (check connections and relays before buying other parts for the system).
Hydraulic fluid leaks.
Parking brake needs regular adjustments.
Ultra-comfortable, elegant ride as a consequence of its interior silence, exclusive suspension and steering and regal leather interior.
