When I first bought my truck, the engine had a surging problem at low idle when it was cold. Once it heated up, the problem went away, so I didnât pay too much attention to it. Then at about 4,000 miles, my truck began running very erratically. Then soon after, my check engine light came on. I took it to a dealership for warranty repair. Their code scanner revealed several misfire codes along with other related codes. This issue seems to be very common for the 2025 RAM with the new twin turbo 6-cylinder engine as noted by many people in online vehicle groups for this truck that have same experience. RAM has acknowledged the issue but dsnât have a fix in almost 6 months later. My truck has been in service at the dealership for over 40 days and I have made several calls to check the status. Each time they say they cannot resolve. They say they have been in contact with the manufacturers âtech line❠and have followed all their recommendations, but nothing has worked and there are no other resolutions available. There is nothing they can do. Due to the misfire code and the check engine light is on, the truck cannot be used safely on the road due to erratic performance. Sometimes on the highway, maximum speed will drop to 40 mph. Misfire codes also present a problem with potential engine damage. Also, I am obviously worried about my state SAFETY inspection that is due in another 6 months that would certainly fail leaving me unable to legally operate the vehicle. Since this seems to be a mysterious issue that Stellantis/RAM is unable to understand, much less repair, I am worried about potential long-term issues with this truck. Stellantis will not publicly state how many occurrences there are for this situation, but if online groups are any indication, it is a large number.
