4 Ram EcoDiesel Years To Avoid

2014, 2015, 2016, and 2017 are the most problematic years for this impressive Ram engine. Issues related to engine functioning, emission systems, and EGR coolers were common across all the worst years, with each of them having some other issues limited to them.

1. 2014 Ram EcoDiesel

2014 was the debut year for the brilliant Ram engine and came with its fair share of teething problems. This was understandable, as most of the vehicle components, when they debut, contain some issues. Minor problems can be ignored, but the 2014 EcoDiesel was suffering from some major ones.

Owners reported numerous issues, including:

• Engine Problems: Early buyers faced issues with engine reliability. There were several complaints, ranging from loss of power to complete engine failure.
• Transmission Problems: Many buyers were outraged with the transmission acting up. Sometimes the transmission would abnormally shift out of drive while in motion, noisy cold starts, RPM without acceleration, transmission bumping when acceleration or releasing the brake, and noisy low speeds.
• Exhaust System Issues: The Diesel Particulate Filter (DPF) system was another common issue for the 2014 model year. It usually led to frequent regeneration cycles and, in some cases, DPF failure. 
• Recalls: This model year had 14 recalls, and most of them were related to engine control module (ECM) software updates and other emissions-related components.

2. 2015 Ram EcoDiesel

The model year 2015 saw some improvements over the last one, but the engine continued to suffer from several issues. This time the engine had 17 recalls, and most of them were related to engine, fuel system, gearbox, and electrical issues.

Owners were crippled by prominent issues:

• Emission Control Problems: This issue was carried on from 2014 to 2015. This ongoing problem with the emissions control system led to additional software updates and recalls.
• Oil Cooler Failures: There were a huge number of buyers reporting oil cooler failures, leading to potential engine damage if not addressed immediately.
• Turbocharger Issues: Not many, but some models from this year experienced turbocharger failures. This was a concern as it was leading to costly repairs that not everyone could afford.
• Technology Failures: This model year also suffered from GPS and Uconnect systems failing, the radio not working, and various warning lights turning on the dashboard without any reason.

3. 2016 Ram EcoDiesel

The next one on this list of which ram 1500 eco diesel years to avoid is the model year 2016. Ram had addressed some of the earlier issues for this year, but the EcoDiesel still wasn’t trouble-free.

This year too, it had about 11 recalls and was suffering from issues like SCR catalyst system failure, airbag malfunctions, shifter linkage problems, cruise control issues, and troubles with power door locks and rear tailgates.

The prominent issues with the 2016 EcoDiesel were:

• EGR Cooler Failure: The exhaust gas recirculation (EGR) cooler in this year’s models was prone to cracking, leading to coolant leaks and potential engine overheating. If left unchecked, it could lead to engine failure.
• Continuing Emission System Woes: The emission-related problems persisted this year as well. Many owners had complained about experiencing issues with the Selective Catalytic Reduction (SCR) system.

4. 2017 Ram EcoDiesel

As the EcoDiesel entered its fourth year of production, it showed further improvement from its introduction year. However, some issues still lingered. Complaints related to coolant leaks due to cracked EGR, DPF/SCR issues, and transmission shifting problems were highly common.

• EGR Cooler and Turbocharger Issues: The problems related to EGR cooler and turbocharger issues slipped into the 2017 model year. Many owners had complained about the problems. However, the frequency of reports related to these issues was lower compared to previous years.
• Transmission Problems: Another old problem that made its way this far was related to transmission. Many buyers of the 2017 Ram EcoDiesels experienced transmission issues, mainly with rough shifting and occasional transmission failure.

2018 Model Year and Beyond

From 2018 onwards, the models featuring the Ram EcoDiesel showed good improvements in reliability. The automaker was able to address many of the recurring issues, and the builds of these later model years have received fewer complaints and recalls compared to the worst years for the engine. Not only this, but the introduction of the third-generation EcoDiesel engine in 2020 brought some significant enhancements in performance and durability.

Most Common Problems With Ram EcoDiesel

The Ram EcoDiesel has become a popular choice among pickup lovers since its introduction. It was like a breath of fresh air that offered more power at the cost of less fuel and better handling, making it the perfect partner for a vehicle. Ram produced EcoDiesel for almost ten years, and in these years, there were some troublesome model years that were infested with problems that cannot be ignored.

The Ram EcoDiesel has suffered from about five major problems and a few minor problems. The occurrence of these issues was generally triggered when the engine was used beyond its limits.

Fuel Injection System Problems

The oldest and most common problem with Ram EcoDiesel engines is related to the fuel injection system. This issue generally arises after 100,000 miles of usage and has affected the worst years the most. The pumping motors and fuel injectors in this engine are inferior to what Ram stated in the model descriptions. Regular maintenance, fixing the fuel line, and replacing the fuel filter on time are the only ways to avoid this issue.

Turbo Failure

The occurrence of minor issues like oil seal leaks, compressor damage, worn-out bearings, malfunctioning turbine wheels, and sticky VGT was common for Ram EcoDiesel, which eventually led to a major turbo failure and an expensive repair. Fixing a turbocharger issue costs around $400 to $4000, making it a matter of concern for buyers.

Cracked EGR Cooler

The cracked exhaust gas recirculation (EGR) cooling systems and diesel particulate filter (DPF) failure problems were another common yet big issue with the new Ram engine. The inappropriate hot and cold engine cycle, heat exhaustion, and body warming lead to deeper cracks and severe damage to EGR valves in EGR coolers.

This problem plagued the older model years the most. Ram did try to handle it for new model years, but the buyers were still dissatisfied with the new engines’ subpar cooling and hose quality.

Glow Plug Problems

The starting issues with Ram EcoDiesel engines were reported by the NHTSA. According to the complainants, they had a hard time starting their rides. As soon as they put their keys into the ignition, they hear a brief clicking sound, but the engine does not start. This starting problem in Ram Truck’s primarily occurs due to the damaged or blown-out glow plugs. The white smoke coming out of the exhaust pipe is the major symptom of this issue.

Ram glow plugs typically last around 90,000 to 120,000 miles. However, an unstable power supply, damaged wiring, an uncontrolled voltage supply, and engine overheating can cause the glow plugs to fail prematurely. Thus, the ideal way to avoid the blown glow plugs would be to replace them as soon as you hit 100,000 miles.

Oil Cooler System Malfunction

Overheating is another common problem you can face with your Ram 1500 EcoDiesel purchase. Many EcoDiesel engines were suffering from this problem, which mainly arises due to ineffective coolers.

The poor design was the biggest factor in why this engine’s oil cooler started failing quickly. The cooler gets cracked, overheating the entire cooling system and causing oil pollution. This leads to the oil temperature rising too quickly, reducing the lifespan of the engine due to oil contamination and overheating.

Thus, proper maintenance is a necessity here. If the engine is not maintained well, this problem starts to arise as soon as you have 20,000 or 30,000 miles on your ride.

Timing Chain Problems

Some Ram EcoDiesels face timing chain failure issues. Ram tried to address this issue in mode year 2022 by replacing the piston and valve timing intervals. Despite this, there were still some complaints about the unusual sound coming from the engine, indicating a slipped timing chain. Although it is a minor issue, it is still something prospective buyers should be aware of as it comes with expensive repairs.

TPIM Issues

The issues related to the Totally Integrated Power Module (TIPM) are not widespread among Ram’s trucks. However, it is always wise to know what you might have to deal with with your purchase.

A faulty TPIM is still a headache because it leads to many electrical problems, like a faulty AC system, power windows that malfunction, coolant fans that stop working, and more.

Best Years To Buy Ram EcoDiesel

Despite the many issues haunting the buyers, EcoDiesel engines were a treat to Ram fanatics. While its older releases were somewhat nightmares, the later ones were better and more reliable.

2018, 2109, 2020, 2021, and 2022 are the best years for this Ram engine. In these model years, the engines faced the fewest issues, fewer owner complaints, decreased recalls, and increased reliability.

After the 2018 year, Ram continued the improvements in the EcoDiesel. The one released in 2021 is deemed one of the most reliable eco-diesel engines. As per many owners, the 2021 EcoDiesel is said to be more powerful, quiet, and efficient. It delivers 260 hp and 480 lb-ft of torque.

Not only this, but with it you get 12,570 pounds of towing capacity and 2040 pounds of payload capacity. Furthermore, the fuel economy for the best years is 22 mpg in the city and 31 mpg on the highway. This all concludes that the best years for EcoDiesel are superior in terms of power output and fuel efficiency.

Ram EcoDiesel Maintenance Schedule

Maintenance plays a crucial role in deciding how long you will be able to enjoy driving your EcoDiesel engine. Below, we have some key maintenance tips and schedules that can help you keep your ride in better shape for a long time.

• Engine Oil: Prefer to use the engine oil mentioned in your vehicle’s owner’s manual. And make a habit of changing your engine oil every 10,000 miles.
• Fuel Filter: The fuel filter ensures uncontaminated fuel reaches the engine. In this process, the filter itself gets covered with contamination over time. If left unattended, it can lead to severe engine problems. Thus, change the fuel filter every time you change the engine oil. Generally, it is advised to replace the fuel filter every 30,000 miles.
• Differentials: You must change the differentials of your ride after every 20,000 miles you hit on your vehicle.
• Transfer Case Fluid: It is ideal to change the transfer case fluid every 30,000 to 65,000 miles. To know for sure, refer to the owner’s manual.

Why Did Ram Discontinue The EcoDiesel Engine?

Ram discontinued the production of their EcoDiesel engine in January 2023. One of the biggest reasons for this decision is that, like most other automakers, Ram is also shifting its focus toward electric vehicles. Ram is all under work and has said that by 2025 they will introduce a battery-electric Ram 1500 Ramcharger.

While electric vehicles are taking the world by storm, gasoline and diesel vehicles are not obsolete. Ram’s shift to EVs and discontinuing the EcoDiesel so abruptly is the reason why the demand for this engine in the used car market has gone up in the last year.

EcoDiesel is nothing but a miracle baby of Ram that you should go for if you want to own a rare build. However, to ensure you are buying something worth your money, explore the ram ecodiesel years to avoid and the years to buy. This way, you will not end up with a busted model.

Tips For Buying a Used Ram EcoDiesel

Now that we have covered everything from the best and years of EcoDiesel along with the engine’s most common problems and must-know maintenance schedule, it is time to move ahead and check how you can successfully buy the right pickup engine. Follow the tips mentioned below, and you will be able to get the best ride available on the market.

Ask For Vehicle History

Whether you are buying your EcoDiesel vehicle from a private seller or a dealership, always ask for the vehicle’s history. This will tell you if the vehicle was in any accidents in the past, if there were any issues with it, and if there were any recalls. Never buy a vehicle without having a comprehensive vehicle history report in your hands.

Ask For Maintenance Records

Used vehicles are more susceptible to issues compared to brand-new ones. So, ask your seller to provide maintenance records. This will tell you whether the vehicle was maintained well through the years or not. This will keep you from investing in a ride that is poorly maintained.

Stay Firm On Pre-Purchase Inspection

Have a trusted mechanic inspect the car thoroughly before buying it. This way, you will be able to learn if there are any underlying serious issues and can steer clear if such a thing happens. If your seller refuses to fulfill any of these three demands, it is a clear indicator that something is wrong with their vehicle, and you should drop the idea of purchasing your EcoDiesel from them.
