Fitment & sizes

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

From the factory this vehicle uses OE oil filter 12737090. Note the factory engine air filter and fuel filter are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 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 federal record provided covers 1991–1993 rather than the 1989 model year itself, so the 1989 Skyhawk must be assessed primarily on its own profile of three complaints — one each in Structure, Latches/Locks/Linkages, and Power Train — with zero crash and zero fire incidents. Across the visible 1991–1993 arc, complaint volume remained low (one, then two, then two), recalls were absent, no investigations were opened, and exactly one TSB was filed each year, indicating a stable, low-severity pattern through the latter portion of this generation. The 1989 model fits comfortably within that mild envelope, with its complaints spread across three distinct, non-safety-critical areas rather than concentrating in a single failure mode, and the data does not specify any particular root cause for them. The principal caveat is that 1989 is absent from the year-by-year comparison and the absolute complaint counts are small, which limits how much weight can be placed on any trend inference. On balance, the 1989 Buick Skyhawk looks like a defensible used-vehicle purchase, though a pre-purchase inspection focused on the structure, door latches/lock linkages, and powertrain would be prudent given the documented complaint areas.
