Chevrolet Trailblazer: Owner Complaints and Recalls by Model Year
This is the Chevrolet Trailblazer complaint and recall record by model year (2002–2022). 6,852 owner reports are on file across 9 years. 2005 has the highest count (1,450) — often because that year has had longer to collect reports, not because this page ranked it. Open a year to see what owners named, the recall list, and the filings themselves.
Chevrolet Trailblazer filings that NHTSA splits across body-style names are combined here. Related weight classes stay separate.
Across these years, owners named Fuel system more often than any other part of the truck. Unclassified leftovers from NHTSA are not a diagnosis.
In plain English
Across 9 years of the Chevrolet Trailblazer, owners named Fuel system more often than any other system. That is a pattern in the file, not a diagnosis of the vehicle in the driveway.
2005 has the most reports (1,450). Older years collect more filings just by being around longer. Open the year you are actually buying — not the peak year unless that is the one in the listing.
Each row is a model year. The system column is what owners named most that year. Click the year for the inspect list, the recall campaigns, and the owner text.

Do these counts mean the Chevrolet Trailblazer is unreliable?
