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 Note the factory front wiper blades and serpentine belt are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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.

In 1993 the model recorded 243 federal complaints, 1 recall, 3 investigations and 24 technical service bulletins. That complaint count exceeds the 224 logged in 1992 but is lower than the 205 reported in 1994, placing 1993 near the peak of the early‑1990s complaint arc. The 1992 year had two recalls and four investigations, while 1994 saw none, indicating a slight de‑escalation of formal enforcement after 1993. The most frequently cited problem areas in 1993 were Service Brakes, Hydraulic (72 complaints), Power Train (31), Electrical System (26) and Engine & Engine Cooling (23), with 14 crash‑related and 27 fire‑related complaints noted. Because the year shows a relatively modest recall record and the complaint volume is comparable to surrounding years without a clear upward trend, the data does not flag a systemic defect, making the 1993 LeSabre a reasonable purchase option.
