2021 Chevrolet Trailblazer
Alright, here’s a breakdown of common issues reported for the 2021 Chevrolet Trailblazer, structured as requested.
The 2021 Chevrolet Trailblazer is a subcompact SUV designed to offer a blend of style, fuel efficiency, and technology. It’s available with two engine options: a 1.2-liter turbocharged three-cylinder engine producing 137 horsepower and 162 lb-ft of torque, and a 1.3-liter turbocharged three-cylinder engine producing 155 horsepower and 174 lb-ft of torque. The 1.2L engine is exclusively paired with a continuously variable transmission (CVT) and front-wheel drive, while the 1.3L engine comes standard with the CVT on front-wheel-drive models and an optional 9-speed automatic transmission when equipped with all-wheel drive. Owners generally appreciate the Trailblazer’s attractive styling, user-friendly infotainment system, and nimble handling. However, common criticisms include the small rear seat, somewhat underpowered base engine (especially the 1.2L), and occasionally unrefined CVT performance.
