Known issues on the 2002 Century. Owners have lodged 154 complaints with NHTSA about the 2002 Century. The engine and engine cooling draw 25 of them, the electrical system and exterior lighting 24 apiece, and visibility 21, with hydraulic service brakes behind at 14. Among those complaints, 9 reported a crash, 7 an injury and 4 a fire. That spread points to the cooling system, the lighting and electrical system, and the brakes, and the manual meets it with procedures, specifications, torque values, wiring diagrams and diagnostics for those systems.
