Engine

6.7L Power Stroke Turbo Diesel V8

• Turbocharger Failure
  • Description/Symptoms: Loss of power, excessive black smoke, unusual turbo noises (whining or screeching), check engine light.
  • Solution: Replace the turbocharger. Sometimes, the issue stems from oil leaks causing premature turbo failure. Regular oil changes and monitoring oil levels can help prevent this.
  • Estimated Cost to Fix: $2,000 - $4,000+ depending on the shop and whether a new or remanufactured turbo is used.
  • Recalls: None Found
• Glow Plug Issues
  • Description/Symptoms: Hard starting, especially in cold weather, excessive white smoke on startup, check engine light.
  • Solution: Replace faulty glow plugs and, if necessary, the glow plug control module.
  • Estimated Cost to Fix: $300 - $800+, depending on the number of glow plugs needing replacement and labor costs.
  • Recalls: None Found
• Fuel Injector Problems
  • Description/Symptoms: Rough idling, misfires, decreased fuel economy, excessive smoke, check engine light.
  • Solution: Replace faulty fuel injectors. It’s often recommended to replace all injectors on a bank to ensure even fuel delivery.
  • Estimated Cost to Fix: $800 - $3,000+, depending on the number of injectors replaced and labor.
  • Recalls: None Found

Summary

The 2015 Ford F-350 Super Duty is a capable truck, but owners should be aware of some potential issues. Diesel engine problems such as turbocharger and fuel injector failures can be costly, while the 6-speed transmission may experience shuddering or harsh shifting. Suspension wear is typical for a heavy-duty truck, and electrical issues such as alternator failure can also occur. Rust can be a concern, especially in areas with road salt. Overall, while some issues can be expensive, regular maintenance and prompt attention to problems can help keep the F-350 running reliably.
