Drove for about 17 miles and parked at a store. Within 5 minutes of parking the truck, white smoke could be seen coming from the hood on the passenger side. As I approached the truck flames came out from under the hood in the same area. Grabbed a fire extinguisher and returned within one minute to find entire engine compartment in flames. Unable to open the hood so the fire extinguisher was not much good. Fire department arrived within 5 minutes but it was too late. Insurance company took possession of the truck and totaled it. Unknown if it was ever determined what caused the fire. Updated 7/26/18

While towing a travel trailer, accelerator was applied to allow me to pass some slow semi's. There was no response from the accelerator as I held it down for about 10 seconds. Exhaust brake engaged!! It wasnt even on!! However, I had the cruise control on but not engaged. I quickly engaged the resume feature and used the accelerate function of the cruise control to speed up to avoid an accident. This has happened on multiple occasions but this by far the scariest. Also the exhaust brake engages when not even on at random coasting times when not hauling anything. It is very dangerous to not be able to control a big truck due to these glitches. Also two of these Firestone tires have worn bald at 18000 miles. Accelerator has no response when a quick stop and go transition is applied.

Accelerated onto highway entrance ramp and vehicle continued to accelerate on its own up to 80+ MPH. Required hard breaking to get vehicle under control since the electronic ignition will not allow it to be turned off unless the transmission is in park. Required such heavy braking that brakes smoked for several minutes once vehicle was shut down. This incident would have resulted in serious injury and damage if it occurred on city streets. Truck is a 2014 with 10650 miles on it. Vehicle was towed to dealer for repair. Searches on the internet revealed the occurrence of many incidents with Dodge and Ram electronic throttle controls and I'm surprised none have been reported to the national highway transportation safety administration.

After letting up on the accelerator for a moment, then attempting to accelerate, there is no throttle response for 1-2 seconds. In conditions such as changing lanes into faster traffic, or pulling out into traffic from a slow roll, the vehicle decelerates or fails to accelerate, causing a hazard to oncoming traffic. This issue is easily demonstrated while driving by momentarily removing your foot from the accelerator pedal, then immediately attempting rapid acceleration as if pulling into a faster moving lane of traffic. This "dead pedal" behavior has been well documented by numerous owners of late model Ram 2500/3500 with cummins diesel engines.

Tl contact owns a 2014 Dodge Ram 2500. The contact stated that while driving approximately 55 MPH, the diesel exhaust fluid warning light and a warning message advising the contact to see the dealer illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. Additionally, the contact stated that the temperature gauge on the driver's side mirror failed to operate in colder temperatures. The dealer diagnosed that the temperature sensor failed and made the necessary repairs. However, the failure recurred. The manufacturer was made aware of the failure. The approximate failure mileage was 8,000.

This vehicle has the worst acceleration and take off I have ever noticed. If I had to get out of the way of something, I would not be able too. If not fixed this will defiantly cause an accident. I can't even pull out onto the highway and get up to the same speed as other traffic. When I got in my wreck in June I was trying to pass someone who was driving slow and I could not get around them quick enough and they cut me off causing our vehicle to collide.

This truck has a very capable motor. However, the electronics governing the motor have made it unsafe. When you floor the gas pedal (and really need the truck to move for safety, to clear an intersection or merge) there is no response. Knowing trucks like I do, this vehicle should have more than enough power to move swiftly but instead it just crawls due to electronic regulation on the motor. This is a huge safety concern.

Tl* the contact owns a 2014 Dodge Ram 2500. The contact received a notice for NHTSA campaign number: 14V635000 (engine and engine cooling, fuel system, diesel); however, the parts needed for repair were unavailable. While waiting at a traffic light, fuel fumes emitted into the vehicle. The failure recurred intermittently. The manufacturer was notified of the failure. The approximate failure mileage was 3,000.

The vehicle has serious issues with it's emissions system. First the EGR was replaced at a dealership for $2,000 and they must not have reprogrammed the computer because after the installation the entire exhaust system failed and it went into limp mode at 10 MPH and now it is another $7,000 repair. Dodge should be recalling this truck for emissions system problems since it's apparently a known issue.
