2014 Ram 1500: engine overheating

Filed Jul 12, 2025 · Fuel system · CA

The fuel pump in the 2014 Dodge Ram 1500 Longhorn Lemaire overheats while driving with less than a quarter tank of petrol. Stalling during acceleration, prolonged cranking durations prior to ignition, and abrupt power loss at highway velocities causes significant warning signs. Engine surges at times and cause irregular idling. Whining and buzzing sounds emanating from the fuel tank region. Decreased fuel efficiency without justification. The check engine light is illuminated with fuel pressure-related codes (P0087, P0190). Research indicates that 4th generation Rams (2009-2018) frequently experience failures owing to inadequate factory pumps and issues with the TIPM (Totally Integrated Power Module) relay. The fifth-generation vehicles (2019 and beyond) exhibit a reduction in failures; nonetheless, they remain susceptible to contamination from degraded plastic tanks when ethanol-blended gasoline is utilized over extended periods, and pressure below requirements indicates pump failure.

When driving vehicle with my with the check engine light appeared. We were on interstate and truck would not accelerate above 45-50 mph with intermittent surges. I called dealership and they took in my vehicle and replaced the Module Powertrain Control stating that would fix issue. After replacing MPC they check engine light was still not repaired. Dealership told me that fuel pump, fuel lines, intake manifold, and coolant leak needed to be repaired, I asked dealership if that would fix issue and they stated that they did not know and were working with Chrysler/Dodge/Ram to resolve. After a total of 7 weeks the repairs are still not completed. Prior to picking up vehicle I called FCA USA LLC and asked what was being done to get recalls repaired and received responses that repair solution has not been sent to dealerships and another stated parts were not available. I picked up truck and was told that I would need to add coolant every 3 days and not let the fuel level get low to keep fuel pump from failing. I spoke with FCA - Dodge ram and they stated they still do not have parts or a repair for the two recalls mention. In addition the coolant leak would not be repaired under warranty since I had the EGR and intake replaced as a recall due to a failure in 2021. They stated warranties do not apply to recall work. My concern is that they cannot fix the two outstanding year old recalls and have no direction for dealerships. How do I get these issues fixed?

Drivers side rear airbag goes flat intermittently. This may happen while driving or while parked and not running. The dealership could not find any leaks or problems. When flat, even if compressor is running , it won't refill. It may stay flat for minutes or days, and through many driving cycles then all of a sudden it fills and operates normal. Normal operation may last from a few hours to weeks. Then it does it again. Dealership claims it is the airpump overheating but this doesn't make sense as only one shock goes flat and doesn't respond when the pump is running. Many people report this same problem on this year dodge ram truck and have said replacing the compressor and valve body did not fix the problem. One person reported that they had the control module re flashed and it fixed the issue.

Received a letter from fca, titled, approved emissions modification disclosure 3.0l diesel. Took letter and visited dodge dealer, they did not know anything about the letter and stated that they could not do anything without a recall number. I have since monitored motor for any signs of overheating or loss of cooling fluid. The truck continues to have low gas mileage, shifts hard and at high RPM. When first started is sluggish and I have to drive cautiously as it hesitated on take off.

1. Had to replace the exhaust sytem because the automatic exhaust stopped working after towing the truck to the dealer to create a forced regen 2. Replaced 2 turbos 3. After emission recall was completed, engine was loosing antifreeze and overheated. Added antifreeze several times and then the engine started blowing white smoke, engine knocking like a loose crank or rocker arm truck lost complete power. The truck was delivered to ram dealer in riverhead, after spending 1600 dollars for engine diagnosis, which was clear apparent to anyone , the said engine was no good.

Suspension system (air bags) go out. The system completely shuts down and truck will hit the road (even flat new road) really hard with any bump. Usually it starts with one side the driver back side and eventually both air bags go out. Is very dangerous because if a little bump can manage to move my steering, a big pot hole can make my whole truck changes lanes. The system detects the malfunction after 3 uses and says "suspension overheated" suspension cooling". This happen every day for the last 2 months . The more use in the day, the more pull, the more weight, it goes out. I can't use the truck for what is for and now is only a carpool truck. Dodge ram longhorn 2014

The vehicle had a bad egr cooler that caused the coolant to enter the combustion system causing excess overheating of the exhaust melting several exhaust components. It was hit enough to potential cause a fire.

My wife and I were on a long road trip with our infant during christmas. All aspects of my truck were operational and no warning signs. My truck is an ecodiesel. On the way home the temps were below freezing and it began to rain. We tried to turn the heat on in the truck to find there was no heat. The truck was running at normal operating temperature with no signs of overheating. We kept driving until I could safely exit the highway. We fueled up and I checked the truck over visually but found no reason for the truck to have no heat and still be operating under normal temperatures. We returned to driving and had heat for a brief moment before it stopped working again. Still the truck was operating at normal temperature. When I finally decided to check the antifreeze level, I learned that the truck was very low and did not have enough to fill the heater core, but just enough to keep the truck from overheating. I added antifreeze and continued to drive the truck for a couple of weeks and could not determine where the leak was. Finally, after reading several others having the same issue, I discovered a hidden leak in the egr cooler that was essentially leaking and burning off immediately leaving no trace behind of the leak. It eventually got bad enough that it would leave coolant puddles under the truck. Even with the pool of coolant under the truck, there is no visible evidence of the leak except for minor dampness around one port of the egr cooler.
