NHTSA's VIN data lists these trims for the 2024 Trailblazer. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 33 complaints with NHTSA about the 2024 Trailblazer. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2024 Trailblazer over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
General Motors, LLC is recalling certain 2024-2025 Buick Envista, 2024-2026 Buick Encore GX, Chevrolet Trailblazer, and 2025 Chevrolet Trax vehicles. The rearview camera screen may display a distorted or blank image.

Another letter will be mailed once the parts are available. Owners may contact Chevrolet customer service at 1-800-222-1020 or Buick customer service at 1-800-521-7300.
