2002 Chevrolet Suburban 2WD

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2002 Suburban 2WD.

Transmission Automatic 4-spd

The 2002 Chevrolet Suburban 2WD is a full-size SUV equipped with a 4-speed automatic transmission and an engine requiring 6 quarts of 5W-30 API oil, achieving EPA fuel economy ratings of 15 city, 20 highway, and 17 combined mpg. With 456 total owner complaints on record, this model year falls below the model's highest complaint year of 1994 (1,004 complaints) but above the lowest year of 2024 (37 complaints), placing it in the middle range of the model's reliability history. The top complaint area—service brakes, hydraulic—highlights a specific concern, meaning the 2002 Suburban is not among the most problematic years but still carries a moderate complaint volume that researchers should note when evaluating its long-term dependability.

Fitment & sizes

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

From the factory this vehicle uses a BCI 78 · 600 CCA battery, OE oil filter 12731172. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 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.

Owner complaints about the 2002 Chevrolet Suburban 2WD lead in one area — the service brakes, hydraulic, 82 of 456 reports (18%), well ahead of the next concern. None of this vehicle's 4 recall campaigns target the service brakes, hydraulic, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 30 of the reports describe a crash and 6 a fire — a small share of the total, but worth weighing against the service brakes, hydraulic pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
