What Years of Ram Cummins to Avoid?

When it comes to purchasing a used Ram Cummins truck, there are certain years of production that you should avoid. The 6.7L Cummins turbodiesel engine was introduced in 2007 and underwent several improvements over the following decade. However, some early model years have been known for having issues with their transmissions, fuel injectors and other components.

Specifically, models from 2007-2013 should be avoided as these engines are more prone to mechanical failure due to underdeveloped emissions systems which can cause additional wear on the engine over time. Additionally, many owners report excessive oil consumption from the 7th generation 6.7L Cummins motor while others have experienced premature turbocharger failure due to exhaust gas recirculation (EGR) problems and inadequate cooling capabilities within the system design.

While any model year of the 5.9 Cummins can be considered a great buy, there are certain years that stand out as being especially good choices due to their availability, performance potential and overall reliability.

For those looking for an old-school mechanical injection pump, 1998 and earlier models are ideal because they were built with mechanical fuel pumps before electronic pumps became standard beginning in 1999.
