Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2014 Ram 2500 owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2014 Ram 2500. The contact stated that after parking the vehicle, there was diesel fuel leaking from the vehicle. Upon inspection, the contact discovered that there was diesel fuel leaking from the fuel filter connected to the diesel fuel heater. The vehicle was not yet repaired. The local dealer and manufacturer were contacted but no assistance was offered. The contact was informed that the VIN was not included in the NHTSA Campaign Number: 14V635000 (ENGINE AND ENGINE COOLING, FUEL SYSTEM, DIESEL). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 165,000.
The contact owns a 2014 Ram 2500. The contact stated while driving 45 MPH, the vehicle started to jerk, slipped into neutral, with the RPM being raised abnormally. The check engine warning light was illuminated. The contact pulled over to the side of the road and continued driving the vehicle very slowly. The vehicle was taken to a local AutoZone to be diagnosed. The contact was informed that 5th and 6th gears were in incorrect gear ratio. The local dealer was not contacted. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 177,038.
The heater in my pickup was not working correctly on the driver's side, so I took it into a shop to have the engine coolant flushed ($150). Within a few weeks, I had a check engine light appear and discovered the thermostat had failed ($350). I had this replaced. Still no heat. It was discovered that my heater core was plugged, could not be flushed, and the sediment from the coolant breaking down caused the failure in the thermostat, the heater core, and had plugged the EGR cooler ($3459 repair). Eide Chrysler informed me they had had a number of these issues occur this winter alone on Ram trucks from this vintage and mentioned Chrysler had changed coolant beginning with Ram model year 2013, and that said coolant was routinely failing between 60-100K miles. Chrysler stated they would not stand behind the repairs since the original warranty had expired. …
Upon starting the trucks engine, putting the transmission in gear (either Reverse or Drive), at idle engine speed (approx 700-800 rpm) or very low (near idle speed) the trucks engine starts to surge from idle then drops down to 500 rpms with a voltage drop (5V) too. It will do this a couple of times and then the trucks engine dies (engine stops) while in gear and no codes are shown on the CEL or saved in the vehicle control module. When I put the transmission in Park, the trucks engine restarts without a problem. But when I go to Drive or Reverse gear it then will do it again. The truck sounds like the engine brake is being applied causing the engine to lug/bog down. The torque converter has been inspected and replaced. The fuel pump/lifter has been replaced. The batteries have been replaced. The fuel filters have been serviced; the crank case breather has been serviced. …
on the 6.7L cummins diesel engines, as part of the cold start system, there is a bolt in the intake plenum that can come loose and eventually break off getting sucked into the #6 cylinder. when this happens, there will be catastrophic failure of the engine. This boltis barely visible looking from the top driver side of engine, a sure sign of this problem is the preheater wire connected to the intake plenum will seem loose and you can wiggle it. This is not repairable from the exterior of plenum and must be torn down for repair or replacement. If this problem is not noticed, eventual total failure of the diesel engine will happen, not maybe, but will potentially destroy the engine. numerous reports in the repair field have identified this problem and it needs to be addressed ASAP .... …
While towing a moderately loaded trailer, the cooling fan on the engine turned on. It appears the fan shroud got sucked into the fan causing pieces of the shroud to get thrown into the radiator, which in turn destroyed the radiator and leaked all the coolant onto the ground. A quick google search shows this seems to be an extremely common issue with these trucks. It seems that the design of the shroud is poor and should be remedied by the manufacturer. With such a sudden failure this left me stranded just over the top of a hill in the middle of the road with no safe place to pull over, creating a serious hazard.
I recently received a letter in the mail from FCA US LLC, about an emissions recall (Emissions Recall VB6 or 67A) on this 2014 ram. The recall covered many emissions components including the diesel exhaust fluid components. The recall letter also said that if I had replaced or repaired any of these components in the past, I may be eligible for a reimbursement. I had previously had to replace my Diesel Exhaust Fluid Pump back in 2021 and turned in the receipt for the work, but the claim has been denied. I just wanted to reach out to see if there was anything that done to help possibly get the reimbursement.
I was contacted to complete a recall on my truck, (67A), which I had performed by the local dealer. The recall notice also said "If you have already experienced this condition and previously paid for a repair, you may be eligible to receive a reimbursement." I spoke to an individual and followed the instructions to submit a claim. With no response, I tried to get a status; to confirm proper items were received electronically. I was told, they were received and the claim was denied? No reason or justification. I tried many times and was disconnected after asking to speak with a manager/supervisor.
Check engine light came on end of November 2025 and stayed on. Immediately I took the truck to two different independent mechanics. They both said it was a problem with the turbocharger but I never received a recall regarding this. They both said I could still drive it and that it would not leave me stranded. The last recall done was the 67A a year ago. There are currently no recalls for my particular vehicle through the NHTSA. The truck is currently having the very expensive turbocharger replaced by one of the independent mechanics. Why wasn't I alerted to this problem?
RAM has Turbocharger/actuator high failure rate. I have had 2 turbo failures in under 80,000 miles. When I lost the turbo I loose the exhaust brakes. This is very dangerous when towing and coming down a mountain road. This could lead to vehicle damage and loss of life. IN FACT: RAM on the 2015 model year only, issued a warranty extension for Turbo failures. This is serious safety concern due to NO exhaust brakes or no acceleration when needed to avoid a collision.
