2001 Buick Park Avenue

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 Park Avenue.

Body PASSENGER CARTransmission Automatic 4-spd

The 2001 Buick Park Avenue arrived as a passenger car paired exclusively with a four-speed automatic transmission and an engine requiring 4.5 quarts of 10W-30 API oil, returning EPA fuel economy of 17 city, 27 highway, and 20 combined mpg. Across the model's 1994-to-2005 owner-reported record, this year logged 65 complaints — a modest figure that places it well below the troubling 1997 peak of 301 issues and roughly eight times the eight complaints recorded for the 2005 model year, signaling that the Park Avenue was settling into a more dependable phase by 2001. Steering emerged as the leading complaint area for the generation, while two recalls completed the official record.

Fitment & sizes

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

From the factory this vehicle uses a BCI 78 · 690 CCA battery, OE oil filter 12731175. Note the factory fuel filter and cabin air filter are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 every 7,500 mi; spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 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.

Every 7,500 mi	Engine Oil (drain & refill) · Engine Oil Filter (replace) · Tire & Wheel Assembly (rotate)
Every 15,000 mi	Cabin Air Filter (replace)

Reliability & federal safety record

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

In the Park Avenue lineage, 2001 marks the low point of consumer complaints, dropping to 65 after a peak of 301 in 1997 and a gradual decline through the early 2000s. Recall activity also eases, with only two recalls in 2001 compared with three in the surrounding years (2000 and 2002) and a higher recall count earlier in the generation. Technical Service Bulletins, however, surge sharply to 368 in 2001, continuing an upward trend that peaks at 506 by 2005, indicating manufacturers were addressing many issues through service advisories rather than formal recalls. The most frequent complaint categories for 2001 are steering and visibility (each 9 reports) followed by electrical system (8), while crash‑related complaints are minimal (3) and fire complaints remain low (6). **Takeaway:** 2001 shows fewer owner complaints and recalls than most surrounding years, but the high volume of service bulletins suggests underlying issues that required dealer attention; it is a relatively safe year to buy, provided the vehicle’s service history confirms those bulletins were completed.
