- Start with not working - it accounts for 25.4% of failed tests on this model.
- Then check missing and too high, the next two most common reasons.
- The most common advisory is has a serious fluid leak (5.5% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 19,976 miles, which is the number to compare any advert against.
