At what mileage does the body typically fail?
Based on the 9 complaints filed, body issues most often appear around 3,285 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
