As we were traveling home from Florida to Oklahoma our truck completely lost power on a very busy two lane highway in Titus County, Texas. We were pulling our travel trailer which is 40.6 feet in length. We had no warning and had a hard time finding a place to pull over. The dash light then flashed “ exhaust system service required see dealer”. Our truck only has 11000 miles and is well taken care of. As a result , we had to wait for over 2 hours in the Texas heat (91 degrees) on the side of a dangerous highway. Nothing would work in the truck. It took this long for the warranty service to approve the tow. They did not provide any information for rental car or lodging. Our 5th wheel RV is in a tow yard and we are stranded in Tx.They cannot look at our truck until Monday June 27th.

0N 4/4/2022 while traveling on interstate 64 E in WV ,towing an R V camper , no warning signals on the dash screen, my truck started losing power and went completely dead,just missed by a tractor trailer rear ending me, as I rolled off to the side of the road. Iwas towed to the nearest Dodge dealership. When I arrived at the dealership a mechanic came and open the hood, he found diesel leaking and a metal rod of the camshaft sitting on top of the engine, which he stated shot through the engine block. Warranty company doesn't want to tear down engine after I gave approval to investigate issue. This is my work truck and source of income. Four weeks later, I am not getting help from dealership that sold me the truck and warranty. Warranty company is trying to use loop hole to get out of paying. I found similar complaints, reported to the federal safety agency, engines falling apart while driving down the road. I had to pay for my truck to tow from WV to Charlotte NC to my driveway. I have a case# with the Dodge Customer Care Department and they are just informing me that the truck has recalls, but parts are not avaible at this time.

I was driving my truck towing a fifth wheel trailer weighing over 10,000 pounds on a rural state highway in Missouri with many hills, curves, and little to no shoulders. As I was traveling on a downhill slope at approximately 60mph my engine abruptly died with no warning, causing an immediate loss of power steering, power brakes, and engine brake. I began applying heavy pressure to the brakes slowing the vehicle and began looking for a side road to pull into. I came upon a driveway with an open gate into a field. With much manual force to the steering wheel and brakes I was able to guide the truck and trailer off of the highway into the field to a stop. I was fortunate to not have anyone stopping in front of me as I am certain I would not have been able to avoid a crash with the heavy load and no power. The vehicle was towed to a local Ram dealer and metal shavings were discovered in my fuel system. Repairs were made under warranty and after 6 weeks my truck was returned to me with a new fuel system including a new Cp4 fuel pump that had failed. This happened on 08/28/2020 and the truck had 8900 miles at the time. On 09/15/2021 I discovered metal shavings in my rear fuel filter while doing routine maintenance The truck was running appropriately with no codes or warning lights, it had 72000 miles at the time. I telephoned a local Ram dealer shop and was told it would have to be diagnosed at their shop. Unwilling to take the chance with another Cp4 pump failing I contacted a local diesel shop and was advised to replace the Cp4 with a Cp3 pump. I purchased a new Bosch Cp3 fuel pump specifically modified for replacement of Cp4 pumps in Ram trucks and paid the local shop myself to do the work. I still have my second Cp4 pump in my possession.

We were driving our 2020 ram 3500 diesel with a 2000-pound truck camper in the bed on a city street attempting to make a right turn through a yield sign when the engine suddenly stopped completely without the ability to restart it. This resulted in sudden loss of acceleration, power steering, and power breaks, leading to a near collision with a large pole and possibly other vehicles in the in the intersection. Although we missed the pole and other vehicles, it was extremely difficult to avoid due to loss of power steering and braking. Had our speed been slightly higher, a collision would have been unavoidable. After having our truck inspected by the dealership, it was determined that the cause of the engine breakdown was the bosch cp4.2 injection pump catastrophically failing (or "grenade-ing" or "imploding" as the dealership put it) resulting in the complete destruction of the entire fuel system, stopping all fuel flow to the engine. After this happened to us, we did some research and found that the bosch cp4.2 injection pump has been determined to be incompatible with diesel fuel found in the USA due to lack of lubricity, and has other fundamental design defects that together make catastrophic failure almost inevitable in vehicles driven in the USA. Most previous ram 3500's used a reliable bosch cp3 injection pump, but starting in 2019 model years switched to the less expensive cp4.2 even though this issue has been known to ram and cummins due to the countless incidents of catastrophic failure in other vehicles using the same pump for many years. Had we known this prior to purchasing our truck, we would not have purchased it. We were surprised and disappointed to find out that vehicles using this dangerous injection pump have not been recalled.
