RAM Ecodiesel Years to Avoid Before Buying

The RAM EcoDiesel is popular among truck fans looking for power and fuel efficiency. Unfortunately, not all model years have been trouble-free. Some RAM EcoDiesel trucks have experienced engine failures and pricey repairs. Knowing which years to avoid can help buyers avoid unneeded money and stress. 

In this article, we’ll look at the RAM EcoDiesel years with the greatest issues so potential buyers can make an informed decision before buying a used vehicle.

What Is the RAM Ecodiesel?

The RAM EcoDiesel is a diesel-powered version of the RAM 1500 pickup truck engineered for fuel efficiency and good towing capabilities. It was introduced in 2014 and is powered by a 3.0-liter V6 turbocharged diesel engine that provides superior fuel economy than standard gasoline engines. 

The EcoDiesel engine has a strong torque output that make it perfect for towing and off-road driving. However, some model years have experienced reliability concerns and expensive repairs. Despite these problems, the RAM EcoDiesel is still popular for truck buyers who want a blend of power and efficiency.

Common Problems in RAM Ecodiesel Trucks

Here are 7 most common problems that were reported in RAM Ecodiesel trucks:

Engine Failures

There have been many premature engine failures in the RAM EcoDiesel due to poor lubrication and excessive oil consumption. These failures usually come with a heavy price tag because they call for a whole engine replacement. Regular maintenance is helpful, but design flaws in some model years make engine breakdowns more likely.

Exhaust and Emissions Issues

The RAM EcoDiesel was subjected to many emissions-related recalls because it did not meet EPA standards. The EGR system was prone to clogging due to carbon buildup, which led to overheating or in the worst-case scenario, even engine fires. Secondly, software related to emission cheating warrants legal battles in courts which depreciates its resale value.

Turbocharger and Fuel System Issues

Turbocharger failures are a common problem that leads to reduced power and poor fuel efficiency. Fuel injectors in some models have also failed prematurely, causing misfires and rough idling. These issues require expensive replacements and can impact the truck’s reliability.

Transmission Issues

Some RAM EcoDiesel models have problems with the shift feeling rough and experiencing gear slippage, especially in earlier model years. The 8-speed automatic transmission also generates electronic failure, causing the driver’s irresponsible behavior. A faulty transmission can be costly, and some owners have replaced their transmission before reaching high mileage.

DEF System Failures

Many owners of RAM EcoDiesel experience headaches from the DEF system. The problems have clogged injectors, faulty sensors, and fluid crystallization. All of these create warning lights and decreased performance. Repairing DEF system failures is costly and requires a complete system overhaul.

4 RAM Ecodiesel Years to Avoid

RAM EcoDiesel is one of the most sought-after options among truck buyers who are looking for both power and efficiency. Still, not all years have proven to be reliable. Some years have been hit by major engine failures and expensive repairs. The following are some RAM EcoDiesel years to avoid due to severe problems.

2014 RAM EcoDiesel

The 2014 RAM EcoDiesel was the first model to carry the 3.0L V6 diesel engine. Though it had an improved fuel economy and towing capacity, it had many early production problems:

• Engine failure from poor lubrication and excessive oil consumption.
• EGR issues that caused overheating and some fires.
• Recalls for non-compliance with EPA standards for emissions.
• Turbocharger failure and cracked exhaust manifolds are costly repairs.

2015 RAM EcoDiesel

The 2015 model also had many of the same issues as the 2014 version. Minor improvements aside, some problems persisted:

• DEF (Diesel Exhaust Fluid) system failures led to warning lights and expensive repairs.
• Turbocharger failure which lowers the efficiency and power of the engine.
• Legal issues, as these are part of the emissions-related class-action lawsuits and recalls.
• Poor durability over time caused many trucks to need major repairs before achieving the same high mileage.

2016 RAM EcoDiesel

The 2016 model was not all that much improved, as it still had issues like the following:

• There were limp mode problems where the truck would sometimes cut out power and slow down.
• Transmissions, especially the 8-speed automatic transmission which started to fail too early in life.
• Continued emissions problems caused government investigations and recalls.
• The EGR system proved costly and a full replacement was needed.

2019 RAM EcoDiesel

After a short break in production, RAM brought the EcoDiesel back for 2019 and this one had the following issues:

• Fuel injector failures that caused rough idling and misfires.
• Oil dilution was an issue and caused premature engine wear.
• Fuel economy was lower than some expected, with some owners reporting worse mileage than they did.
• Software-related performance issues and multiple updates and recalibrations were needed.

How to Avoid Buying a Problematic RAM Ecodiesel?

Here is how you can avoid buying a RAM Ecodiesel that has faults:

Check Vehicle History Reports

Before buying a used RAM EcoDiesel, always review its vehicle history report from services like Carfax. These reports provide details about previous owners and any major repairs or recalls. Avoid trucks with multiple past owners or a history of major mechanical issues.

Get a Pre-Purchase Inspection

You should have a professional mechanic inspect the truck before finalizing the purchase. They will check for signs of engine wear, emission system failures, and transmission troubles. A detailed inspection will reveal potential costly repairs and ensure the truck is in good working order.

Check for Recalls and Technical Service Bulletins

Check the model year for any RAM recalls or Technical Service Bulletins (TSBs). They reveal important issues that are not complete recalls but require dealer action. If the truck has outstanding recalls or unresolved TSBs, it is preferable to have them addressed before purchasing.

Select a Well Maintained Model

A well-maintained EcoDiesel truck is less likely to experience serious difficulties. Look for a truck with a consistent service history and DEF system maintenance. Avoid vehicles with evidence of neglect, such as black smoke from the exhaust or dashboard warning light.

Avoid High-Mileage Trucks with Unknown Maintenance History

High-mileage trucks such as those over 150,000 miles equipped with the EcoDiesel can remain reliable if serviced well. However, make sure to be clear of the poor service history of trucks such as those that have had few oil changes or have not serviced the transmission. Always ask for copies of maintenance records to get good care.

Research the Best Model Years

Some model years of the RAM EcoDiesel are more reliable than others. Avoid the 2014, 2015, 2016, and 2019 models. Instead, consider later models like 2020 and newer which have improved reliability and fewer recalls.

Conclusion

The RAM EcoDiesel is an excellent choice for fuel economy and carrying power. However, some model years have important issues. If you’re looking to buy a used RAM EcoDiesel, look into its history and avoid trucks that have been poorly maintained. Choosing a trustworthy model year and researching before purchasing will help you avoid costly repairs and long-term concerns.
