Owner-reported
2009 Audi A4 mileage at failure
71 of the 120 complaints on file for the 2009 Audi A4 give the vehicle's mileage when the problem happened.
| Component | Median | Middle half | Based on |
|---|---|---|---|
| Engine | Median 80,000 miles | Middle half 60,000–95,000 miles | Based on 40 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.
