Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses OE oil filter 12731175. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter at 7,500 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 1994 Buick Century sits at a notable inflection point in the model's history. Complaints jumped sharply to 147—nearly triple the 52 recorded in 1992—while recalls surged to 6, the highest count seen up to that year in the dataset. This spike coincides with a jump in TSBs from 8 in 1992 to 36 in 1994, suggesting the manufacturer was addressing emerging field issues. Notably, 1994 recorded zero NHTSA investigations, unlike 1991, 1992, 1997, and 1998, indicating the complaint surge was addressed through recalls rather than federal probes. The trend shows that post-1994, complaints remained elevated (117-252 range through 2000) before declining in later years, with 1998-1999 representing the peak complaint years. The top complaint areas for 1994—service brakes, air bags, and vehicle speed control—point to safety-critical systems. **Takeaway:** The 1994 model year experienced a clear quality decline relative to the early 1990s, with elevated complaints and recalls concentrated in safety systems. While not the worst year in the generation (that honor belongs to 1998-1999), it is not the most reliable entry either. A buyer should budget for thorough brake and air bag inspections and verify that all applicable recalls were completed.
