2004 Chevrolet Trailblazer mileage at failure

885 of the 1,078 complaints on file for the 2004 Chevrolet Trailblazer give the vehicle's mileage when the problem happened.

Mileage at failure by component, from owners' complaints to NHTSA
Electrical SystemMedian 65,000 milesMiddle half 50,000–85,000 milesBased on 528 complaints
Fuel/Propulsion SystemMedian 85,000 milesMiddle half 55,000–115,000 milesBased on 120 complaints
Exterior LightingMedian 85,000 milesMiddle half 65,000–115,000 milesBased on 75 complaints
Power TrainMedian 60,000 milesMiddle half 30,000–100,000 milesBased on 52 complaints
EngineMedian 55,000 milesMiddle half 25,000–90,000 milesBased on 43 complaints
Air BagsMedian 55,000 milesMiddle half 30,000–105,000 milesBased on 33 complaints

A component's median is its 50th percentile, and its middle half runs from its 25th to its 75th percentile.

Owners give the mileage themselves, often as a round number, and NHTSA doesn't check it. A complaint that names several components counts under each one, and mileages that can't be right, such as 999,999, or 50 miles on a five-year-old car, are left out.

These figures describe the complaints owners filed. They don't predict when a particular vehicle will have a problem, and vehicles that never had one aren't counted.
