Had to stop urgently, and my truck shut off. I had to shift it into park to get it started again. Was in the middle of a 4 lane section of route one traveling with traffic at the time. I was a sitting duck until I could figure out what happened. (I’m a mechanic, if the average person was dealing with this I don’t know if they would have been able to get moving as quickly.) It acted like the torque converter stayed locked while I came to a complete stop stopping the engine at the same time. No shuddering or anything obvious. Engine wasn’t running when I came to a stop. i only noticed because it was abnormally quiet and didn’t move when I stepped on the throttle. I’ve owned this truck since the end of July 2025, it was a brand new left over 2024, currently has around 8,500 miles on it)
The truck is currently exhibiting a loud metal tapping/ slapping/ ticking noise when driving from the engine. It is loud enough it can be heard over road/ wind noise, it can also be heard in high idle situations. The truck has been to the dealer where it was purchased and they refused to research the issue because of a current RAM service bulletin that the noise is “under investigation”. It has 6,000 miles and the noise started immediately after the first oil change.
While driving my Ram 2500 completely shut off just like I had hit the engine stop button. Luckily, I was traveling at a low speed at the time, so I was able to coast to a complete stop, put the truck in park on the side of the road. I was then able to restart the vehicle and resume driving without any more issues.
Lifters are failing with 31,000 miles. There are thousands of these trucks with less than 30,000 miles on there second or third set of lifters. I took the truck to Allen Samuels Dodge in Aransas pass Texas for a loud rattling kept the truck several days couldn’t figure it out. I recorded a video of the banging inside the engine they kept the truck 5 days or so gave me a letter saying it’s under investigation and I should call Ram about the lifters. Called Ram they said call the dealer or take it to another dealer. Service guy was like yeah the lifters are failing left n right and locking up the engine. The grid heater bolt is burning off and falling into the number 6 piston on these trucks locking up the engine. I have numerous screen shots from several Ram 2500 groups where people are getting new engines just for it to fail in 3000 miles. I’ve got a 70k truck I’m afraid to drive worried it’s going to rattle apart and lock up the engine while driving down the highway. I can screen shot way more complaints. There’s even someone who started a data base in online forums to record complaints. The transmissions are failing in these 2018-2024 Ram 2500 6.7 Cummins and the gas version to. It’s ridiculous
