2006 Hummer H3 mileage at failure

282 of the 361 complaints on file for the 2006 Hummer H3 give the vehicle's mileage when the problem happened.

Mileage at failure by component, from owners' complaints to NHTSA
Component	Median	Middle half	Based on
Electrical System	Median 90,000 miles	Middle half 55,000–115,000 miles	Based on 81 complaints
Engine	Median 70,000 miles	Middle half 50,000–100,000 miles	Based on 74 complaints
Visibility/Wiper	Median 85,000 miles	Middle half 70,000–115,000 miles	Based on 38 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.
