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 97,500 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 2025 Chevrolet Blazer represents the continued maturation of this generation, with federal complaints declining to 26 from 38 in 2024 and 37 in 2023, preceding the single complaint recorded for 2026. This model year sits near the tail end of the arc that began in 2019 with 182 complaints and peaked at 211 in 2020, demonstrating a steady downward trend in reported issues as the platform aged. Technical Service Bulletins dropped sharply to 171 from 409 in 2024, indicating diminished service activity, though the federal data does not specify root causes for the remaining complaints. The top complaint categories include Electrical System with 5 instances and Unknown Or Other with 3 instances, alongside minimal safety concerns evidenced by only 1 crash-related complaint and zero fire complaints. Given the low complaint volume, stable recall activity, and significantly reduced TSB counts compared to 2019–2021, the 2025 Blazer presents as a favorable used purchase within this generation.
