The 2018 Tesla Model X has an overall defect rate of 129.16 per 100 vehicles, which is 7.6% higher than the average car of the same year, recorded at 120.02 per 100 vehicles. Issues related to tyre condition are prevalent, notably with significant counts of dangerous defects like worn tyres and tread depth non-compliance. In terms of reliability, the Model X demonstrates superior performance in several categories, particularly in steering, lights and electrics, and equipment, where defect rates are considerably lower than the average. However, it shows notable weakness in wheels, suspensions, and axles, with a defect rate of 174.57, significantly exceeding the average of 124.53. Overall, while the Model X excels in certain areas, particularly with electrical systems, it struggles more than average regarding suspension-related defects.
