[1] The Trailblazer was launched on April 16, 2019, at the 18th Shanghai International Automobile Industry Exhibition alongside the Tracker, that replaced the outgoing Trax.

The Trailblazer made its North American debut at the Los Angeles Auto Show in November 2019, and sales began in early 2020 as a 2021 model year vehicle.

Imported from South Korea, it notably reused the nameplate from the previous GMT360 platform-based Trailblazer which was discontinued in the same year.

The L, LS, and LT are the "core" models of the Trailblazer lineup, and feature more traditional exterior styling.

Changes include a new front fascia of a curvier design, new front bumper, new running lights, new LED taillights, new exterior colors, new wheel designs, and the interior receives a larger 11-inch touchscreen infotainment system (available with wireless Apple CarPlay and Android Auto) and 8.8-inch digital instrument cluster.
