“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.”

“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. …”

“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. …”

“Purchased a new Ram 2500 diesel. After 1200 miles, the diesel emission fluid (def) gauge became erratic and gave me a message that after 200 miles the truck's maximum speed would be 5 miles/hour. The am dealer in olympia, wa traced the problem to a computer module. This module is on national backorder with no delivery date in sight. I am on my way to alaska, and am stuck in olympia, wa for who knows how long. The truck is in perfect working order, except that it is programmed to stop (or go 5mph) after 200 miles unless the def problem is fixed.”

“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.”
