What 54 owners told NHTSA about the 2024 Ram Ram 2500 Regular Cab

At approximately 1750 miles the truck transmission began to shift in lower gears extremely violently. Every time that truck would shift in this manner, it would cause a startle effect and divert my attention away from driving to trying to determine what was going on. I immediately took the truck to my local Ram repair shop where they found metal shavings in the transmission oil pan. They told me I would need a completely new transmission. This is unacceptable with a truck with only 1750 miles on it. The dealership said they would need authorization to replace the transmission and not sure if one would be readily available. This is the fourth time this vehicle will have been at this repair facility. The first three times were for a fault code called Turbo under boost. Way too much downtime for a truck with only 1750 miles. We had to postpone our vacation since this is the only vehicle I own that’s capable of towing our boat and trailer. Because of all these issues, we have not been able to tow the trailer one time with our new truck!!!!!! When I asked the dealership what they thought the problem was they said quality control at the factory and a subpar designed for the product. If Ram doesn’t change the design of this transmission, even with a new transmission installed, I am scared this may happen again and then cause an accident.

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)

Dealer confimed roller lifter failure on 9/23/25, they replaced the roller lifters, push rods, cam shaft and rocker arms. Within 20 miles of picking up the truckl on 10/11/2025 the same noise the repair was suposed to remedy was back adn the same volume/ intensity as before. The warranty repair did not remedy the issue.

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

When truck is in drive and I press the brake to shift to reverse, when I take my foot off the brake truck will go forward before reversing. Dealership says there is no problem with it. I find it to be dangerous.

While driving, the truck began to violently shake when downshifting. As I was exiting the highway and braking, the shaking intensified, and the truck stalled while I was traveling around 30 MPH, causing a complete power loss. To avoid a collision, I veered off the ramp and ended up scraping a road sign, which caused damage to the bed above the right fender, the road sign was intact and there was no damage to the sign. When I attempted to restart the truck and placed it in drive, it accelerated on its own. Applying the brakes only made it accelerate further, causing the truck to lunge forward uncontrollably. I managed to slow it down by putting it in neutral, regaining full brake control. I was able to get the truck to my driveway, but as soon as I turned into the driveway, it stalled again. I had to repeat this process to make it home as I didn't have cell service and was unable to call for a tow. This issue is extremely concerning, a complete power loss while driving, especially one that forces you off the road to avoid an accident, poses a grave safety hazard. My life and safety were jeopardized due to this malfunction.

The transmission failed and is available for inspection. The vehicle lost power at 60 mph in an instant as transmission began to slip on a busy road truck would barely move. The problem was reproduced by the dealer and confirmed. Inspection upcoming. Check engine light went on.
