This 2018 Wrightbus Streetdeck 4DC has a first-time MOT pass rate of just 19.7%, catastrophically below the UK average of 80%, though the silver lining is that zero vehicles in this cohort have recorded dangerous defects. The diesel-only fleet (137 of 139 vehicles) passes at 18.5%, suggesting the issue is systematic to the model rather than fuel type.
These are buses with average mileage of 108,985 miles at six years old—relatively high usage, typical for commercial operation—yet the average of only 0.04 failures per vehicle suggests most don't fail on substantive safety grounds; instead, they're likely failing on minor or procedural compliance items endemic to the MOT testing of large vehicles. If you're considering purchasing one, inspect maintenance records meticulously and budget for pre-test remedial work, as the pass rate points to either poor upkeep across the fleet or recurring minor defects that require addressing before each test.
