2023 Chevrolet Trailblazer

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Trailblazer.

Transmission Automatic 9-spd

The 2023 Chevrolet Trailblazer runs a 9-speed automatic and an engine requiring 4.2 quarts of 5W-30 or 0W-30 oil, carrying EPA fuel-economy figures of 26/30/28 mpg. Within the model’s 1999–2026 complaint history, the 2023 registers only 62 owner complaints—far below the 2005 peak of 1,733 and nearer the 2014 low of 1—with zero recalls and engine-related concerns ranking as the top complaint category. That low complaint count and clean recall record place the 2023 among the more statistically quiet entries in the Trailblazer’s tracked history, even though engine issues remain the primary owner-reported problem area.

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 60,000 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 2023 Chevrolet Trailblazer sits squarely in the middle of a clearly improving arc for the current generation, with complaints declining steadily from 182 in 2021 to 102 in 2022, 62 in 2023, and continuing downward to 32 in 2024 and just 19 in 2025. Recall activity mirrors this trend, dropping from four campaigns in the launch year (2021) to one in 2022 and zero in every subsequent year through 2026, meaning the 2023 model carries no outstanding federal recall obligations. The complaint profile itself is diffuse rather than concentrated — engine, service brakes, and power train each account for only 10, 10, and 6 filings respectively, with no single component dominating — and the four crash-related and one fire-related complaint are low relative to volume. Technical Service Bulletins have also tapered from 746 in 2021 to 472 on the 2023 model, consistent with early production wrinkles being addressed. Compared with the original 2002–2008 Trailblazer era, which saw complaint counts in the four figures alongside double-digit recalls, the 2023 model is a markedly better-behaved vehicle on the federal record. **Bottom line: 2023 is a strong year to consider on a used Trailblazer — it benefits from the early-generation teething issues having been resolved while avoiding the higher complaint and recall load of the 2021 launch year.**
