Defect rate by model year
The BMW Z4, first introduced in 2003, is a compact luxury sports car that has garnered attention for its striking design and engaging driving dynamics. As a successor to the BMW Z3, the Z4 has been praised for its performance and handling capabilities, appealing to enthusiasts and everyday drivers alike. Over the years, it has undergone several updates, with improvements in technology and comfort, but how does it fare in terms of reliability as recorded through MOT inspections?
Examining the MOT data from 2003 to 2022, the Z4 generally demonstrates a strong reliability profile compared to the average vehicles of the same model years. Notably, from 2003 to 2009, the Z4 consistently recorded fewer defects per 100 tests than the average car, peaking in 2009 with just 125 defects, which represents a remarkable 60% improvement from the average. This trend of lower defects continues into the 2010s, with the model showing significant reliability, especially in the latter years.
However, some recurring issues are evident across multiple years. The most common problems reported include brake pipe corrosion, suspension component wear, and tyre tread depth violations. These issues have been persistent throughout the years, suggesting that while the Z4 excels in many areas, attention should be given to these specific components during regular maintenance.
The years 2007 and 2008 were particularly strong for the Z4, with defects per 100 tests declining to 214 and 213 respectively, both well below the average for those model years. Conversely, the earliest years, particularly 2003 and 2005, showed higher defect rates, which may reflect a period of early production teething issues. From 2010 onwards, the Z4 continued to improve, with defect rates dropping significantly, culminating in 2022 with only 40 defects per 100 tests.
