Summary

The 2007 Ford F-750, while a capable truck, can be prone to issues typical of medium-duty commercial vehicles. Engine problems, particularly those involving fuel injectors or the HEUI pump (Caterpillar C7), can be costly. Transmission issues related to shift solenoids or the torque converter are also common. Suspension and electrical gremlins can also appear. Rust can be a significant concern, especially in areas with road salt usage. While not all vehicles will experience these issues, potential buyers should be aware of these common complaints and factor in potential maintenance costs. The severity and cost of these repairs can range from a few hundred to several thousands of dollars, making a thorough pre-purchase inspection crucial.
