From the factory this vehicle uses a BCI 78 · 600 CCA battery, OE oil filter 12731175. Note the factory front wiper blades and cabin air filter are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 10,000 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.

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 2001 Pontiac Montana sits at a transitional point in the first-generation federal record, with 169 complaints—well below the 1999 peak of 262 and the 2000 figure of 250, signaling that the most acute early-life reliability issues were already subsiding. However, 2001 also recorded the highest recall count of the entire dataset at 11 campaigns, and the 387 TSBs represent a steep escalation from the 26 logged in 1997, indicating that manufacturer-identified defects and service bulletins were still being addressed at an unusually heavy clip. The top complaint areas concentrate on engine and engine cooling (32), power train (14), electrical system (12), and fuel system (11)—a powertrain-heavy profile rather than scattered trim issues—and the 10 crash and 3 fire complaints add a safety dimension that warrants a pre-purchase inspection. Relative to its neighbors, 2001 is the most recall-burdened year of the generation, while 2002–2004 show progressively cleaner complaint and TSB-issuance profiles as the model matured. For a used-buyer, 2001 is workable but not the sweet spot of the run; verify that all 11 recalls have been completed and budget for a powertrain-focused mechanical inspection before purchase.
