Summary

The 2003 Dodge H100, being a work truck, is prone to issues related to wear and tear, particularly in the suspension and drivetrain. The 2.5L diesel engine tends to suffer from fuel injector and turbocharger problems, while the 2.4L gasoline engine is known for catalytic converter failures. Common transmission issues involve the clutch in the manual version, and harsh shifting with the automatic. Electrical problems due to wiring harness damage are also prevalent. Exterior rust and interior dashboard cracking are common cosmetic concerns. While some repairs can be relatively inexpensive, major issues such as turbocharger or catalytic converter replacement can become costly. Overall, potential buyers should carefully inspect the vehicle for signs of wear, corrosion, and previous repairs, and budget accordingly for potential maintenance costs.
