Quick summary
Total: 687 cars
The 2014 Tesla Model S shows a slightly higher overall defect rate compared to the average vehicle of the same year, with 194.52 defects per 100 vehicles against an average of 194.3. Notably, the Model S performs better in categories such as steering, lights and electrics, and body/structure, displaying significantly lower defect rates than average. However, it stands out negatively in wheels, suspensions, and axles, with a defect rate of 244.65—higher than the yearly average. The data also reveals a troubling trend with increasing defects reported in higher mileage segments, particularly in the 124,000+ mile category. While tyre wear is mentioned frequently, the underlying concern appears to be more extensive in the suspension and brake systems.
