2002 Buick LeSabre

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2002 LeSabre.

Body PASSENGER CARTransmission Automatic 4-spd

The 2002 Buick LeSabre is a full-size passenger car paired with a four-speed automatic transmission and an engine calling for 4.5 quarts of 10W-30 API oil, returning EPA figures of 17 mpg city, 27 mpg highway, and 21 mpg combined. With 321 owner complaints on record and two recalls, its most frequently cited problem area is visibility, which stands out as the dominant concern among the reported issues. Across the LeSabre's documented complaint history from 1990 through 2006, the 2000 model year represents the peak at 698 complaints while 2006 bottoms out at just three, placing the 2002 model in the declining phase of that curve and suggesting it benefits from the post-2000 corrective trend even as visibility-related grievances persist.

From the factory this vehicle uses a BCI 100 · 770 CCA battery, 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 Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 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.

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 2002 Buick LeSabre sits on the declining side of this generation's federal complaint arc, which spiked dramatically in 2000 with 698 complaints and 5 recalls. For the 2002 model year specifically, complaints decreased slightly to 321 from 340 in 2001, though recalls ticked back up to 2 and technical service bulletins continued their steady climb to 422. While this represents a vast improvement over the 2000 peak, the 2002 model still carries a relatively high complaint volume compared to the steep drop-off seen in 2003 and beyond, suggesting some manufacturing issues were still being ironed out. The primary concerns for 2002 are heavily concentrated in Visibility (104 complaints), followed by Structure (31) and Air Bags (19), alongside 15 crash and 12 fire complaints, though the data does not specify the root causes for these failures. Given its mid-arc position and the significantly cleaner federal records of subsequent years, the 2002 LeSabre is a passable but less-than-ideal purchase, and buyers would be better served by seeking a 2003 or newer model.
