Of the 3 Trailblazer model years with enough complaints to compare, owners filed the most about the 2022 (0.72) and the fewest about the 2023 (0.56), per 1,000 sold in the first three years.
Median across these years: 0.62 per 1,000 sold in the first three years. A model year well above its own nameplate’s median is the signal worth acting on.

Safety complaints owners filed with NHTSA in each model year’s first three years on the road, divided by how many were sold, so a year that sold twice as many cars is not penalised for it.
