The contact owns a 2014 Ram 3500. The contact stated while driving 65 MPH, the "no turbo signal" warning light illuminated, and the vehicle shifted into LIMP Mode. The contact stated that the vehicle slowed to approximately 20 MPH on the highway. The contact pulled over and turned the vehicle off and detached the positive and negative battery terminals. The contact stated that he touched the ends of the cables and reconnected the terminals to the battery and was able to return to normal vehicle functionality. The contact stated that the failure was intermittent but occurred at various speeds. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the turbo actuators needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 116,000.
Turbocharger actuator failure. Recognized as known issue for vehicles manufactured one year later (2015). All replacement cost covered by manufacturer and warranty extended. The replacement part for the 2014 RAM 3500 turbocharger actuator is MOPAR part 68481772AA and the replacement part for the 2015 RAM 3500 turbocharger actuator is MOPAR part 68481772AA (identical part numbers). Similarly, the turbocharger installation kits for both model years are identical. Multiple online complaints noted about failures in 2014 model years. I incurred $3000 expense to replace. Two detailed letters sent to manufacturer with no response or acknowledgement of receipt.
The Turbo Actuator failed while driving on a two-lane highway without a shoulder to safely pull over. The truck lost power down to a maximum speed of 10mph until I could safely pull off of the highway. The problem has been diagnosed with a OBD2 scanner. No other inspections by police or insurance. The MIL did not turn on until the vehicle was pulled off of the highway and at a stop.
I experienced a lack of power and I noticed that the engine temperature jumped by 40F immediately. The EVIC coolant temperature jump rapidly, but I never received a low coolant warning. I pulled the truck off of I-25 Northbound just south of the WY border. I waited for the vehicle to cool and added all of the coolant I had on hand, about 1.5 gallons. I carefully limped into Cheyenne, WY, towing my 40' 5th wheel to a spot where we could stay. I contacted Cowboy Dodge to identify the problem and repair it. The technician looked at my vehicle and he indicated the EGR valve was bad and needed replaced. The repair invoice is attached for reference. We departed Cheyenne after the fix, and we only got 44 miles out of town on I-80 when the engine coolant light illuminated, and the temp started to spike again. …

Vehicle is a 2014 Ram 3500 turbo diesel. The computer systems have required numerous updates and have failed 3 times when travelling. The brakes failed when new and a computer update fixed that after I had an accident. The PCM engine controller failed at 20,000 and shut us down while towing a large 5th wheel. In July 2016 the PCM failed and the def would not feed; again broken down with a large 5th wheel attached to the truck. On October 8, 2016 at 41,700 miles the def system has failed again leaving us stranded again while on the road. It is extremely dangerous to be stuck beside the highway with a broken down truck due to repeated computer failures. This problem is also limiting our travel plans because of the fear and danger associated with an unreliable truck. I think that this truck should be returned to the dealer and we should be given a new truck.
Tl* the contact owns a 2014 Ram 3500. While the vehicle was parked, it caught on fire. Prior to the fire, there was no smoke or abnormal odor in the vehicle.

Low engine RPM throttle response from dead stop or rolling pace (5-35 MPH) experiences 3-5 second lag before engine responds and accelerates. This has caused numerous close calls when turning in front of oncoming traffic on clear road conditions. To compensate, my driving habits have resorted to "power brake" the vehicle to increase engine RPM's in order to accelerate and clear oncoming traffic. I have owned/driven 3/4 & 1 ton cummins diesel vehicles prior to my 2014 model with no similar issues. When towing, the issue is much less noticeable. At this point I am ready to sell and buy another brand due to safety concerns. My wife does not feel safe driving or riding in the vehicle and is concerned that I transport our kids to and from school daily in the vehicle. Online research indicates this is a common issue with this model/year group and has coined the condition as "dead pedal". …

Takata recall after we replaced the fuel pump the truck still didn't perform like it should have for a 2 year old dually with less than 100,000 miles on it. Around 1 year ago, we were driving and suddenly were able to smell an extremely foul smell coming from under the dashboard, upon further examination we discovered that the anti freeze was leaking from somewhere and entering the passenger floor board. After this occurred it seemed as if the truck itself just started to fall apart. Both batteries have had to be replaced countless times as well. The radio and A/C do not work and the heater doesn't come close to getting hot.
