Quick summary

The 2015 Mercedes-Benz G-Class has an overall defect rate of 114 defects per 100 vehicles, which is significantly better than the yearly average of 170 defects per 100 vehicles, showing a reduction of 33%. Notably, the G-Class performs exceptionally well in areas like brakes and wheel suspensions, recording 59% and 61% lower defect rates compared to the average, respectively.

Overall, while the G-Class shows strengths in certain categories, it also faces challenges that may require consideration.
