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.

Owner complaints about the 2001 Chevrolet Blazer 2WD top in one area — the exterior lighting, 57 of 339 reports (17%), well ahead of the next concern. That matters, because the exterior lighting are also the target of recall 08V-231 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 36 of the reports describe a crash and 5 a fire — a small share of the total, but worth weighing against the exterior lighting 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.
