Built from this model's own failure record, not general advice.
- Start with not working - it accounts for 39.8% of failed tests on this model.
- Then check has a serious fluid leak and tread depth is below minimum requirements of 1.0mm, the next two most common reasons.
- The most common advisory is tread depth is below minimum requirements of 1.0mm (7% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 38,941 miles, which is the number to compare any advert against.
