2019 Chevrolet Blazer

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 Blazer.

Transmission Automatic 9-spd

The 2019 Chevrolet Blazer pairs a 5.0-quart oil capacity with 5W-20 or 0W-20 viscosity specs and a nine-speed automatic transmission to deliver EPA ratings of 18 city, 25 highway, and 21 combined mpg. Owner-reported complaints for this model year total 182, with the leading category logged as "Unknown Or Other" and two recalls issued, placing it well below the nameplate's peak complaint year of 1995 at 1,418 but above the 2026 low of just one. That positioning suggests the 2019 Blazer sits in the middle of the model's long-term reliability arc — neither a standout for trouble nor a benchmark for cleanliness — giving researchers a realistic baseline for assessing durability trends across the 1990-2026 span.

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 2019 Chevrolet Blazer recorded 182 complaints, 2 recalls, and 846 technical service bulletins (TSBs). Within its generation, complaints peaked in 2020 at 211 before trending steadily downward to 26 by 2025. As the introductory year, 2019 sits at the start of this arc, characterized by a high volume of TSBs compared to later years such as 2024, which had 409. The most frequent complaint areas for 2019 were "Unknown Or Other" (34) and "Power Train" (31), though the data does not specify the root causes for these issues. Because it avoids the 2020 peak in complaints and recalls, this is a good year to buy.
