How many miles will a 2007 Trailblazer last?
The 628 mileages owners gave run from 10 to 275,000 miles. A quarter are at or under 51,000 miles, half at or under 71,001, three quarters at or under 106,000 and nine in ten at or under 140,000; 179 (29%) came after 100,000 miles, 45 (7%) after 150,000 and 9 (1%) after 200,000.
These mileages say when owners reported a problem, not when a 2007 Trailblazer wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.

Common problems with the 2007 Trailblazer
NHTSA's file holds 732 owner complaints on the 2007 Chevrolet Trailblazer. Owners named the fuel system most often: 215 complaints, and half of the 193 that list a mileage came after 53,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Fuel System, Gasoline | 215 | 193 | 53,800 |
| Electrical System | 200 | 157 | 77,000 |
| Exterior Lighting | 151 | 129 | 113,936 |
| Visibility | 64 | 55 | 75,000 |
| Fuel/propulsion System | 58 | 51 | 82,660 |
Of the 732 complaints, 19 report a crash, 56 report a fire and 16 report an injury (23 people reported injured). These are owners' reports to NHTSA, not findings.
Is the 2007 Trailblazer a good year?
Complaint counts cannot say whether the 2007 is a good or a bad Trailblazer: they rise with how many were sold and how long they have been on the road. They show how the 2007 compares with the other model years in NHTSA's file.
With 732 complaints, the 2007 ranks 6th of the 9 Chevrolet Trailblazer model years from 2001 to 2009 with 10 or more complaints, counting from the most. The most: the 2005 (1,466). The fewest: the 2001 (20).
NHTSA files the Chevrolet Trailblazer name for 2000–2009 and 2021–2026. A gap of three or more model years means the name covers different vehicles, so the 2007 is compared only with the 2000–2009 model years.
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2001 Trailblazer | 20 | 11 | 76,531 |
| 2002 Trailblazer | 1,249 | 846 | 65,000 |
| 2003 Trailblazer | 1,214 | 960 | 73,000 |
| 2004 Trailblazer | 1,342 | 1,109 | 66,000 |
| 2005 Trailblazer | 1,466 | 1,215 | 70,000 |
| 2006 Trailblazer | 1,297 | 1,097 | 65,000 |

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2007 Trailblazer lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2007 Trailblazer.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 104 of the 732 complaints on the 2007 Chevrolet Trailblazer give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA names counted: TRAILBLAZER and TRAILBLAZER EXT. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file names matched: TRAILBLAZER and TRAILBLAZER EXT.
- NHTSA also holds 26 complaints filed as the 2000 Chevrolet Trailblazer. EPA's fuel-economy catalogue lists the Chevrolet Trailblazer for 2002–2026 only, so that model year has no page.
