Quick summary
Total: 3,126 cars
The 2014 Nissan Leaf has an overall defect rate of 236 defects per 100 vehicles, which is 21% higher than the average for cars of the same year. Notably, the Leaf performs significantly better than average in categories such as Lights & Electrics and Body/Structure, with defects in these areas being much lower than typical. However, it struggles with brakes, steering, and wheels, showing a considerably higher defect rate compared to the average, particularly in the brakes category, where the rate is 140 defects per 100 vehicles. As mileage increases, the defect rates also rise sharply, especially in the 124,000+ miles segment, indicating potential reliability concerns as the vehicle ages. Overall, while the Leaf excels in certain areas, it exhibits weaknesses that could impact its long-term performance.
