Engine Problems:
* Engine overheating: This was a recurring issue, often attributed to failing water pumps, radiator problems (leaks, clogs), thermostat issues, or low coolant levels. Regular maintenance is crucial to prevent this.
* Transmission problems: Automatic transmissions were known to be problematic in some model years, experiencing slipping, rough shifting, or complete failure. This is often an expensive repair.
* Leaks: Various leaks were common, from oil leaks (often around the valve cover gaskets or rear main seal) to coolant leaks.
* Mass Airflow Sensor (MAF) issues: Problems with the MAF sensor can lead to poor engine performance, rough idling, and trouble starting.
Electrical Problems:
* Electrical gremlins: Buick Centuries, like many older cars, are susceptible to various electrical issues. These can range from intermittent problems with lights and gauges to more serious electrical malfunctions.
* Window regulator problems: Power window regulators were prone to failure, leading to inoperable windows.
Other Common Problems:
* Suspension issues: Ball joints, tie rod ends, and control arm bushings were known wear items that often needed replacement.
* Brakes: Brake problems could include wear and tear on brake pads and rotors, as well as issues with the brake lines or master cylinder.
* Rust: Depending on the climate where the vehicle was driven, rust could be a significant problem, particularly on body panels and undercarriage components.
* Interior Issues: Common issues included worn interior fabrics, cracked dashboards (especially in sun-exposed areas), and malfunctioning power seats.
Important Note: Not every Buick Century will experience all of these problems, and the frequency and severity can vary greatly. Regular maintenance, including timely oil changes, coolant flushes, and inspections, can help to prevent many of these issues. Thorough pre-purchase inspections are highly recommended before buying a used Buick Century. Checking repair records from previous owners is also a smart move.
