In June 2016, towing a 14 foot light trailer up sonora pass on hwy 108 in California, the truck bucked, studdered and shook in first gear, stalled and slipped backward towards a 1000 foot cliff, it then lunged into gear and it was smoking the tires. I let it do that to gain traction and then slowly made my way back up. I cannot tow anything out of first gear without the bucking and studders, and losing forward momentum, anywhere. Almost lost it all that day including my life and nothing has been done to fix the issue. 2 dealerships in 2 states acknowledge the problem, state they have other customers that have the same problem but Dodge cannot seem to understand a fix or the seriousness of this defect. The truck is not safe to tow anything anywhere and that is obsurd for a Ram 3500. This truck is advertised as the number one truck for towing, but it just can't do the job safely. Please view letter sent to dealership dated July 9th. 2016.

The tuck has a horrible lag in the throttle response. When trying to pull out into heavy traffic the truck lags more than it should. This has been happening since the day I bought it new with 16 miles on it. If you press the pedal more than half down from a stop you can count to 30 before it actually starts moving. There have been multiple times where this has almost caused an accident. I have been reading forums about this issues and have come up with 2 causes. 1 the throttle control programing is set extremely conservative which will cause this. 2 the one that almost everyone is reporting is that the dpf regen system is causing too much back pressure. People are reporting that when they delete the exhaust and egr off the truck it gets its power back. These systems never seem to completely clean out and all wise has high back pressure.

2015 Ram 3500 laramie dually 4X4, 6.7 I6 cummins, aisin transmission. Truck experiences "dead pedal" under hard acceleration or when depressing pedal 3/4 to full throttle suddenly. This happens under all conditions: Stopped, rolling, under acceleration. Advancing the pedal suddenly or completely down in emergency situations results in a 3-4 second delay where the truck will not respond, then slowly adds power. This is extremely dangerous as the truck will not respond to the drivers inputs. Possibly resulting in a crash or death. In several cases the truck has responded in the above described manor resulting in emergency action by the driver to avoid a crash or wreck. Problem has been occurring for the past 10 - 15K miles and still continues. As per the dealer servicing the vehicle. We were told nothing is wrong, this was normal and they refused to do anything about it. As per Ram technical assistance "if the customer steps in the throttle, the vehicle will go into derate to keep the driveshaft off the ground. If you stay around 60 to 70% throttle then there is no derate. Sounds like the vehicle is operating as designed." A copy of the report has been provided with this report

While pulling out into traffic the vehicle went into limp mode and would not speed up. A pop up in the center instrument panel showed service throttle position, took it to dealer said I was driving 2 foot. They said this happens when one foot is on brake and other on fuel pedal. To me this is a big safety concern. I was never told about this and from reading owners manual this was not cover in it. This should not of happen for I almost got rear ended for something that should not be in the system. This is a safety concern that should be taken out of the system completely. I am concern now of what might happen if this does it again while pulling out in traffic even while traffic is pretty clear. But if in a emergency this could be dangerous not only for me but for other drivers. Every one does not drive the same so this should be fix.

Truck has a bad hesitation when running slow and letting off the gas pedal and back in the gas. For example coming to a yield sign slowing down and then pressing the gas petal.....2-3 second delay before truck starts going.

Dead accelerator pedal. When applying accelerator there is a period of time when nothing happens. This is particularly concerning as it leaves the vehicle occupants and the vehicle essentially dead and in harms way while trying to maneuver in traffic, merging, turning, emergency avoidance, etc.
