The 2005 (1,734) and 2004 (1,368) drew the most owner complaints to NHTSA of the 2000–2009 Chevrolet Trailblazer model years on record and the 2021 (201) and 2022 (113) drew the most owner complaints to NHTSA of the 2021–2025 Chevrolet Trailblazer model years on record, as of November 10, 2026.
Close behind among 2000–2009: the 2006 (1,347) and 2002 (1,277).
NHTSA holds no Chevrolet Trailblazer records from 2010 to 2020: the years on either side are different vehicles sharing the name, so each is compared only with its own years.
2000, 2001, 2009, 2024 and 2025 have fewer than 40 complaints on file, too few to compare.
2008 drew under a quarter of the 1,024 complaints of the median 2000–2009 year, too few to name among the fewest.
NHTSA also holds fewer than 10 complaints and no recall for 2014; that stray filing is left out of the table.
Fewest complaints: not named. Fewer than three of the Chevrolet Trailblazer model years from 2000 to 2009 with at least 256 complaints on file, a quarter of the median year’s 1,024 remain once the years with the most are set aside.
Half of the 6,070 NHTSA owner complaints on the 2000–2009 Chevrolet Trailblazer that list mileage came after 69,000 miles (NHTSA complaints file of November 11, 2026). How many miles will a Chevrolet Trailblazer last? →
Chevrolet Trailblazer complaints and recalls by model year, 2000–2025
This table lists the 15 Chevrolet Trailblazer model years NHTSA holds records for between 2000 and 2025, collected from NHTSA’s complaints and recalls APIs on November 10, 2026. Each owner complaint is counted once, by its NHTSA number, and a complaint can name more than one component; recall campaigns are counted once per model year, by campaign number.

Chevrolet Trailblazer by model year: mileage, problems and recalls
Each page below covers one model year in NHTSA’s complaints file of November 11, 2026: the mileage when owners reported problems, the most-reported components and the recall campaigns NHTSA’s recall files list. That file is a separate collection from the table above and goes back to the 1981 model year, so its counts can differ and it holds years the table does not.
How to read these numbers
- A higher count is not proof of a worse vehicle. Complaint volume rises with sales volume and with years on the road, so older and best-selling years collect more.
- The comparison is between years of the Chevrolet Trailblazer only. It says nothing about how the Trailblazer compares with other models.
- NHTSA publishes owner reports without verifying them. A complaint is an allegation, not a defect finding.
- Recall campaigns cover production ranges. NHTSA’s VIN lookup checks open recalls within its coverage and excludes completed repairs. A zero result does not prove the vehicle’s complete recall or repair history; ask for dated repair documentation.
- NHTSA files some years under body or cab names (for example ACCESS CAB or CREW CAB). This collection asked for the names NHTSA lists, and a year far below its neighbours also under the common cab and body names. Such a year is marked as possibly filed under another name only when NHTSA’s records show it split across names or holding recalls and no complaint; otherwise its count is read as low.

Chevrolet Trailblazer year-by-year questions
Which Chevrolet Trailblazer years should I avoid?
Chevrolet Trailblazer years to avoid, by NHTSA owner complaints: the 2005 (1,734 complaints, led by the electrical system at 733 and the fuel system at 511) and the 2004 (1,368, led by the electrical system at 780 and the fuel system at 125) drew the most of the 2000–2009 model years and the 2021 (201, led by the powertrain at 42 and the electrical system at 41) and the 2022 (113, led by the powertrain at 35 and the electrical system at 31) drew the most of the 2021–2025 model years on record as of November 10, 2026; complaints are owner reports, not proven defects, and the counts also reflect each year’s age and sales. Close behind among 2000–2009: the 2006 (1,347) and 2002 (1,277). NHTSA holds no Chevrolet Trailblazer records from 2010 to 2020: the years on either side are different vehicles sharing the name, so each is compared only with its own years. 2000, 2001, 2009, 2024 and 2025 have fewer than 40 complaints on file, too few to compare. 2008 drew under a quarter of the 1,024 complaints of the median 2000–2009 year, too few to name among the fewest. NHTSA also holds fewer than 10 complaints and no recall for 2014; that stray filing is left out of the table.
What are the best Chevrolet Trailblazer years?
Complaint counts do not show which model year is best; the closest they come is which years drew the fewest complaints. This page names none: fewer than three of the Chevrolet Trailblazer model years from 2000 to 2009 with at least 256 complaints on file, a quarter of the median year’s 1,024 remain once the years with the most are set aside.
Do complaint counts mean the Trailblazer is unreliable?
No. NHTSA complaints are unverified owner reports, and the count rises with how many vehicles were sold and how long they have been on the road. They are useful for comparing years of the same model, which is what this page does, not for ranking one model against another.
How do I check a specific Trailblazer before buying?
Take the 17-character VIN from the windshield or driver-door label and run it through NHTSA's free recall lookup. It reports open recalls within its coverage and excludes completed repairs. A zero result is not a complete recall or repair history; ask the seller or manufacturer for dated repair documentation. For the vehicle's own past, the original ClearVIN PDF from VIN Lookup shows title brands, odometer readings, accident and auction records on file for that VIN.
