2008 Chevrolet Blazer: what breaks, and at what mileage
What breaks on the 2008 Chevrolet Blazer
Only 5 defect reports have been filed with NHTSA about the 2008 Chevrolet Blazer, which is too few to compute mileage percentiles or a risk score. The reports reported exhaust leak or fumes in the cabin.
When each failure gets reported
Tick median reported mileage Solid middle half of reports Faint 10th to 90th percentile Colour how bad the failure is when it happens
How reports accumulate
Every report with an odometer reading, cumulative, from 0 to 200,000 miles. A curve that climbs early is a car with early problems, whatever its total.

Every reported failure mode
| Failure mode | System | Reports | With reading | 25th | Median | 75th | Per 1,000 | Typical repair | Severity |
|---|---|---|---|---|---|---|---|---|---|
| Exhaust leak or fumes in the cabin | emissions | 1 | 0 | — | — | — | 8.3 | $250–$2,000 | High |
| Tail light, brake light or signal failure | lighting | 1 | 1 | — | 82k | — | 8.3 | $100–$900 | Moderate |
| Other electrical problem | electrical | 1 | 1 | — | 115k | — | 8.3 | $250–$2,000 | Moderate |
| Other steering problem | steering | 1 | 1 | — | 78k | — | 8.3 | $350–$2,400 | High |
| Other body or interior problem | body | 1 | 1 | — | 54k | — | 8.3 | $200–$2,000 | Moderate |
This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The odometer reading is the one the owner gave.
Tail light, brake light or signal failure
Tl* the contact owns a 2008 chevrolet blazer. The vehicle failed the state inspection. The dealer diagnosed that the brake lights and hazard lights failed and needed to be repaired. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 82,400.
Other electrical problem
The electrical doesn't work in my truck any more. The dash doesn't light and every time I change the fuse it blows. There is no way I can afford to get this fix and is missing up my break lights also. I have read a lot of articles that this is a reoccurring issue with 2008 chevy blazers.
Every year of the Chevrolet Blazer
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2005-2008 generation, 2005 Chevrolet Blazer scores best at 64 and 2006 Chevrolet Blazer worst at 66.
What the reports on file say
The complaints recorded against the 2008 Chevrolet Blazer are exhaust leak or fumes in the cabin (1 report), tail light, brake light or signal failure (1 report, around 82k miles), other electrical problem (1 report, around 115k miles), other steering problem (1 report, around 78k miles) and other body or interior problem (1 report, around 54k miles). With a sample this size these are anecdotes rather than a pattern, and they are shown because somebody looking at this exact car would rather see them than nothing.
Why this page is short
A model year needs about 8 reports before percentiles mean anything, and this one does not have them. Complaint volume tracks how many cars were sold and how long they have been on the road, so a thin page usually means a rare car, a new car, or a car whose owners do not file.
Other years of the same model do have enough: 1996, 1997, 1998, 1999, 2000, 2001, 2002 and 2003. The mechanical parts are often shared across those years, so their pages are the better guide to what this one is likely to do, with the caveat that a shared part is not a shared production line.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
