| Dec 2025 | FUEL/PROPULSION SYSTEM | I was suddenly unable to fill the fuel tank of my truck on the way back from a 4 hour road trip in freezing conditions. I was able to get just enough fuel into my vehicle to make it back due to it occurring during a fuel up on the last hour of the drive. However, if this had happened earlier in the drive, I could have been stranded with my family in freezing conditions. There were no warnings and it hadn't been happening prior, other than a half dozen times randomly over the past 2 years where the fuel station nozzle clicked off a few times prematurely. But never to the extent of not being able to fill the tank. It was brought to a dealership and is currently having the fuel tank replaced due to a bad valve inside of it. | Crash: No Fire: No | Unknown |
| Nov 2025 | SERVICE BRAKES, HYDRAULIC,ELECTRICAL SYSTEM,ELECTRONIC STABILITY CONTROL (ESC) | The contact owns a 2021 Ram 1500. The contact received notification of NHTSA Campaign Number: 24V653000 (Service Brakes, Hydraulic, Electronic Stability Control (ESC); however, the part to do the recall repair was unavailable. The local dealer was contacted, and it was confirmed that the part was not available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact stated that while driving at an undisclosed speed, the message "Battery Low Voltage" was displayed and the vehicle experienced loss of power steering functionality and decelerated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the failure was related to the recall. Additionally, the contact was informed that the E-Torque generator also needed to be replaced but the part was on backorder. The vehicle was not repaired. The manufacturer was notified of the failures. The failure mileage was 110,000. | Crash: No Fire: No | 110,000 |
| Nov 2025 | VISIBILITY/WIPER | My driver sun visor support broke when I tried to pull down the sun visor. It is supported by a plastic piece. If it wasn’t supported on the left side it could have fell down completely blocking my visibility of the road. I looked up this issue online and there are many other videos with the same issue with these trucks. This issue is so persistent that some third party companies have already come out with plastic support pieces to screw in to fix this. I took the truck to the dealer but they said they won’t fix it since my truck is out of warranty. There was no warnings, messages, or symptoms of the problem prior to the failure. | Crash: No Fire: No | Unknown |
| Nov 2025 | ELECTRICAL SYSTEM | All warning lights on dash came on including battery. Freedom Dodge assessed it on 11-10-2025 and said the vehicle generator has an internal short and is discharging the battery. If being operated could cause the vehicle to die while in motion. I am making $700 per month payments and Freedom indicated over 6000 of these units are on back order and cannot give me a date for replacement only saying "months" | Crash: No Fire: No | Unknown |
| Nov 2025 | ELECTRICAL SYSTEM | Body Control Module failure. 2021 Ram 1500 Tradesman with 3.6L engine My first symptom was a message that appeared on the dash gauge cluster that said something like "problem with shift positioner". That message came up then went away. Next symptom was dash lights flashing for no reason. This was a few days after the other. These lights would flash one time for just a fraction of a second, and only when I hit a bump on the road. I thought that I had a loose wire so I checked wiring for loose connection but did not find any. I had no other problems for several days. Then I was on a trip far from home and that is when things got really bad. All of the gauges on my instrument cluster were going up and down for no reason. The windshield wipers came on by themselves. The dash lights started flashing, like before but this time that were on and off for longer periods of time and not caused by bumps on the road. The vehicle lost power while I was driving and I was forced to pull to the side of the road. The engine had died. I was not able to restart right away. While I was sitting there trying to figure out my next move (because I was in the middle of nowhere), the lights on the dash were still flashing even after I had turned the key off. I know that sometimes trouble codes can be cleared by disconnecting the battery, so that is what I did. After I put the battery cables back on, the controls seamed normal again. I was able to start the engine and drive into town. I went straight to an automotive repair shop that I had found by Google search. They put their code reader on and said that I had 59 fault codes. They had never seen that many on any vehicle before. They checked my battery to make sure it was fully charged. It was. They checked a few other things, but diagnosed the problem to a bad Body Control Module. After this incident, I did some research and found that this seems to be a come problem with the Ram Pickups. This should be a recall item. | Crash: No Fire: No | Unknown |

| Sep 2025 | ELECTRICAL SYSTEM,STRUCTURE | While driving the vehice on 9/23/25, it randomly turned off while driving down my street. Took a while to get it started again, then once it was started, it would not turn off. I brought the vehicle to a local shop. There were NO warning lights.The next day they let me know that the issue was from a faulty sliding backlite, there were cracks on the frame by the back windows that caused water to leak down around the window into a control module that was filled with water that caused the vehicle to randomly turn off while driving down the street then later caused it to not be able to turn off. If this issue caused the vehicle to turn off while on a highway or a curvy road it would have almost definitely ended with a severe accident. I got in touch with stellantis and they know about the issue but aren't willing to help in any way. | Crash: No Fire: No | Unknown |
| Sep 2025 | POWER TRAIN,VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM | I was driving on the highway going the speed limit and the car suddenly slowed to 35 and all sorts of lights (check engine light and others) came on and messages went across the screen about the throttle control and stability control. This is the 4th time this has happened to me. Each time I bring it to the dealer and am told "its a known computer glitch" or that there is a fix but it continues to happen again. Suddenly losing power and speed has caused other drivers to slam on breaks, swerve, etc. In order to reset the car I have to pull over on the highway to restart it. This is putting my safety and the safety of others at risk. | Crash: No Fire: No | Unknown |
| Sep 2025 | POWER TRAIN,ENGINE | While towing, my truck threw P00AF-00 Turbocharger Boost Control Module "A" Performance and ABS C121C-00 Torque Request Signal Denied codes and I lost power due to turbocharger not engaging.

The original code was cleared by my hometown dealer and vehicle ran well. 130 miles later it happened again, cleared by dealer in Parkersburg WV On the way home it happened a 3rd time. After parking for half an hour the alarm lights went off and I had full power. A day later the CEL also went off leaving no evidence of a problem on my dash. The vehicle is scheduled at the local dealer tomorrow (9/29/25) The trailer and truck combination was well within the towing limits of the vehicle.
