I have a 2016 Ram ecodiesel fully loaded limited 1500 and I have had nothing but problems with it this past year. I have gone to three different dealerships and none of them can fix the vehicle it only has 40K miles on it and is in perfect condition other than now it is overheating and the fan is on constantly. I believe maybe there is a leak in the coolant line" I don't know, the service departments have been useless, I have been to the dealerships with the problem about 10 times. What do I do? it was a very expensive vehicle and I don't think I should have to be going through this. How do I get Ram to respond? who do I contact to file a complaint with them"

First they told me it was the way Dodge built my truck and that it was normal, then next time we took it in they told me that it was my toll tag, I questioned ok which is it Dodge made my truck this way or my toll tag, we got no response.

The truck was put into park with the key in the ignition and the engine running. It was parked in a restaurant parking lot. Then around five minutes later, it went into reverse and began rolling backwards. It seemed to accelerate. I had to jump in and slam on the brake to stop it. I do not know how this could occur, but have recently learned of recalls for similar situation with the truck in the parked position, but going into gear. Our VIN was not recalled. There were witnesses to this event.

I had a sudden loss of power and an abrupt deceleration while driving out of my development. The service electronic throttle control and check engine lights appeared on the dash. This happened on May 17, 2017 and some of the vehicles ecodiesel fuel injectors were replaced. 2000 miles later almost the same exact thing happened on July 14, 2017. Currently additional injectors are being replaced. I am thankful neither time was while driving at highway speeds on a busy road.

My son was driving South on I-15 towards san diego at 65mph in the travel lane (2nd left most lane) when his new truck suddenly and without warning completely shut itself off. The main screen on the dash prompted to shift into park (the truck was traveling at 65 mph at the time) to restart the truck. He was unable to pull over to the left due to the hov lane being very busy - he traversed three lanes of traffic to the right in a vehicle without power, or steering assist, and an inoperable electrical system. The blinker column switch did not activate the indicator lights. He was able to activate the emergency hazard flasher lights to show his emergent need to stop on the right shoulder. He stopped the truck near exit 31 on I-15 South. He was able to shift the truck into park and restart the truck. He was forced to continue driving the truck to nas North island san diego because he was on the flight schedule for a annual flight evaluation pre- deployment. The vehicle failure could easily have resulted in a fatality if another driver, less able to handle unforeseen dangerous mechanical failures, could have panicked in crowded California traffic. My son states that he has lost confidence in the vehicle, moreover that it is dangerous to the vehicle occupants and individuals who might be involved in a crashed caused by the sudden failure of the vehicle systems.

When removing foot from accelerator, vehicle stays at 1450 rpms, causing the vehicle to go 10-15 miles per hour. It is unsafe for my wife or daughter to drive. After two service visits, I am told that it is normal. It did not do this problem during first 1500 miles.

When the vehicle is warm, after about 1/2 hour of driving, the transmission starts to drive rough. When I come to a stop it feels like someone hits me from the rear. When I'm driving around 35 mph and slow down it down shifts hard (clunk). When I'm driving at speed on the highway and I go to pass, when it press on the gas pedal there is a long hesitation and then it bogs down then accelerates. It's scary my wife gets nervous when she's driving. The longer you drive it the worse it gets. I have 9,500 miles on it. After driving it on the highway and you exit to the streets the gas pedal has a lot of play in it-about 1.5 inches from when you press on the pedal to when it kicks in and then the response is a bit jerky. I brought to the dealership on 9/26/2016 and they said they couldn't replicate the issue. I explained that they needed to drive the truck for a while. When the truck is cold it's ok, no issues. Iv'E talked to my local mechanic who has 40 plus years working on cars and he told me that he's heard the same complaint from other Ram truck owners. He told me to register the complaint...thanks [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
