Common Problems With Ram 1500 Ecodiesel
Engine Failure
The EcoDiesel engine is known for main bearing failures and connecting rod problems. Owners of earlier models report engines stopping suddenly, especially around 100,000 miles. Repairs can cost $7,000–$12,000.
Emissions Issues
Many years faced recalls for emissions cheating and excessive NOx emissions. This led to expensive repairs and lawsuits. Some models have EGR valve and DPF filter failures, costing $2,000–$4,000.
Oil Leaks
EcoDiesel engines often suffer from oil cooler leaks and rear main seal leaks. These problems can cause low oil pressure and engine damage if not fixed quickly.
Turbocharger Problems
Turbo failure is common, especially in models before 2017. A broken turbo can mean slow acceleration and poor towing. Replacement costs are usually $3,000–$5,000.
Electrical Issues
Some years have issues with wire harness corrosion, faulty sensors, and random warning lights. These problems can be hard to diagnose and fix.
Comparing Ram 1500 Ecodiesel Reliability By Year
To help you see which years are most problematic, here is a quick comparison.
| Model Year | Main Problem | Repair Cost | Owner Complaints |
|---|---|---|---|
| 2014 | Engine Failure | $7,000+ | High |
| 2015 | Emissions & Oil Leaks | $4,000+ | High |
| 2016 | Turbo Failure | $5,000+ | Medium |
| 2017 | Electrical Issues | $2,000+ | Medium |
Insight: Later years (2018+) improved, but early models still set the tone for reliability concerns.

How To Spot A Problem Ecodiesel
If you’re shopping for a used Ram 1500 EcoDiesel, watch for these signs:
- Check engine light that stays on
- Oil stains under the truck
- Strange noises from the engine or turbo
- Rough idling or trouble starting
- Excessive smoke from the exhaust
Ask for maintenance records. A well-serviced EcoDiesel is less likely to have major problems.
Maintenance Costs Compared To Other Trucks
EcoDiesel repairs are usually more expensive than gas trucks. Here’s a quick comparison:
| Truck Model | Average Annual Maintenance | Major Repair Cost |
|---|---|---|
| Ram 1500 EcoDiesel | $1,000 | $7,000–$12,000 |
| Ram 1500 Gas | $800 | $4,000–$7,000 |
| Ford F-150 Diesel | $950 | $6,000–$10,000 |
Tip: Diesel parts and labor cost more. Budget for higher expenses if you buy an EcoDiesel.
Non-obvious Insights For Buyers
- Warranty history matters more than mileage. Many EcoDiesel problems appear after the factory warranty expires. Trucks with extended warranties or full dealer service records are safer bets.
- Short trips are hard on diesels. EcoDiesel engines need to warm up and run at highway speeds to keep emissions systems clean. Trucks used for short drives often develop more problems.
Alternatives To Ram 1500 Ecodiesel
If you want reliability and lower costs, consider these options:
- Ram 1500 Gas models: Fewer engine problems, cheaper repairs.
- Ford F-150 Power Stroke: Better reliability, but higher purchase price.
- Chevrolet Silverado Diesel: Good fuel economy, fewer emissions recalls.
What To Do If You Already Own A Problematic Ecodiesel
Stay on top of maintenance. Use high-quality oil and change it often. Fix leaks and issues quickly. Consider joining online forums for support and advice.
