Common Warning Signs That Need Attention

Recognizing the early warning signs of Cummins diesel problems can save you thousands in major repairs. Hard starting, especially in cold weather, often indicates issues with your grid heater or lift pump that need prompt attention. Excessive black or white smoke from your exhaust typically points to fuel system problems involving fuel injectors or injection pump timing. If you’re experiencing loss of power during acceleration or while towing, this could signal turbocharger issues or concerns with your DPF regeneration cycle. P-pump issues in older 5.9 Cummins engines create distinctive symptoms, including rough idling and fuel delivery problems that our technicians can diagnose quickly. DPF regeneration problems are widespread in 6.7 Cummins engines, especially if you primarily drive short distances or in stop-and-go traffic. Our diagnostic process at CDT Automotive includes comprehensive testing of your 68RFE or Aisin transmission, as these components work closely with your Cummins engine. You can reach us at (919) 698-7118 to schedule an inspection if you notice any concerning symptoms in your Ram diesel truck.
