Conversely, it performs better than average in the wheels, suspensions, and axles category, indicating fewer issues compared to similar models. Mileage trends reveal that as the vehicle ages and accumulates mileage, the defect rate increases, especially noticeable in higher mileage ranges. Overall, the Relay's reliability could be improved, especially regarding visibility and electrical systems.
