The service engine lamp came on. When the mechanic investigated, it was determined that the problem is identical to the Warranty Bulletin titled Cummins 6.7L Turbocharger Actuator - X99 Warranty Extension that pertains to the 2015 RAM 2500 pickup. My vehicle is a 2016 and there is no warranty extension, even though it is an identical problem. The vehicle was not drivable as is and I had to replace the Turbocharger Actuator. I am assuming that this is a known problem to Cummins and to RAM. There should be a Warranty Bulletin for the 2016 also.

My vehicle has was has been coined as "dead pedal" the truck will hesitate for a second while accelerating. This problem has been well documented by many other ram diesel truck owners. This will happen when merging into traffic or crossing a street and can be very dangerous.

Not sure if this is the right place for this but figured it was a start. I have a 2016 ram 2500 with the cummins diesel. Every so often the truck leaks fumes into the cab of the truck. I have read on many forums online it seems to be a common problem not only with the 1500 eco truck but with the bigger 2500,3500 trucks. Ram says there is no problems from what I have read but it seems to me that this is a serious safety issue!! One guy posted that ram just told him to use the recirculate button to stop the smell. That's fine and dandy but when you do that you can not use the defrost witch is a problem in the right weather conditions because the windows will fog up. So you have to roll the windows down to get fresh air. I would appreciate any info you have on this issue or could point me to the right agency that could help me force ram to fix this problem. Agian big safety problem! If someone has no sense of smell like one of my best friends hthey could pass out while driving and kill himself if someone else. Thanks again

Tl* the contact owns a 2016 ram 2500. While driving 75 MPH, the vehicle independently slowed and stalled without warning. The contact was able to restart the vehicle. The failure recurred ten more times. The vehicle was taken to a dealer where it was diagnosed that the vehicle was supposed to reset the regeneration system to clean the diesel particulate system while driving. However, the reset was failing and caused the vehicle to slow and stall. The vehicle was not repaired. The manufacturer was made aware of the failure and stated that the contact should take the vehicle to the dealer as many times as necessary. The approximate failure mileage was 15,000.

Driving on interstate 10 in traffic I went to accelerate to change lanes and my 2016 2500 the engine made a loud pop and lost all engine power. And didn't regain engine power for 3 seconds. It has done it several time since. It is a very scary feeling when your driving in heavy traffic. I do not get any codes or lights indicating a problem when this happens. Was told by dealer service manager that without any codes coming up that it would be impossible to find the problem.

Numerous times the diesel has stuttered and acted like it was going to die. This has happened several times. Was taken to sealer and was told there is nothing wrong with it. It is making weird noises while shifting and is now throwing a cel with the code p0421.

2016 ram 2500 crew cab 4x4 6.4 liter v8 - my truck is 5 months old with 4,500 miles on it. I have had this problem two times so far. I would be driving and the check engine and throttle positioning sensor warning lights come on. The truck would lose acceleration and sometimes the truck would accelerate on it's own and could drive itself on the road (sometimes surging). I have had it tot the dealership two times so far. The first time they replaced the throttle. The second time they said it was a bent clip on the throttle wiring harness for the throttle. The same thing happened two other times since it was last fixed on 8/30/2016, but if you let the truck sit overnight, the next morning everything would be fine. The punch line is that I have owned the truck for 169 days (as of today) and it has been in the shop 37 of those days (so far) with serious electrical issues. The last two issues are serious enough that the truck will accelerate on its own and is unsafe to drive. I have had it towed by ram the last two times to the dealership. Outside of the fact that the truck has been in the shop for 22% of the time I have owned it, I am more concerned about the serious safety concerns these issues cause and I have lost faith that this truck can be fixed. When this problem occurs, it could easily cause and accident to include injury or death. This is a 6,500+ pound vehicle! Please look into this problem with ram.
