    I have had 2 separate instances where I had my foot on the brake and the accelerator kicked in, the engine revved up and the truck tried to move forward all while I had my foot still pressed down as hard as I could on the brake. Once the engine was not revving any longer, I put the truck in park and sat for a second so I could gather my composure. After I sat for a second and put it back in Drive it didn't do it again. This happened in the same manner both times. It happened once in October 2024 and the 2nd time in January 2025.

    The truck has 58,xxx miles and on my way home from work today it just shut down in the middle of the highway. I could start it back up but as soon as I would shift into gear it would shut down again. Finally, after about 15-20 times of starting it and it shutting right back off, it stayed running and got me to within 5 miles of my home before doing it again. Now, I can’t get it to stay running so I’m going to have to have it towed in to be checked. I was able to get it off the road but it was extremely dangerous shutting down on a busy highway. I see that it has a recall that I hope will fix this issue when I’m able to get it taken in

    I was driving East bound at 8:00 am into the sun. I lowered my sun visor to block the sun. About 15 mins down the road the sun visor assembly completely separated from the ceiling mount. Looking this issue up online I found a YouTube video of another owner who had the same problem. Many comments from viewers describing that their drivers sun visor has separated from the mounting bracket. My truck only has 26k miles on it and it’s not even 4 yrs old yet, but out of warranty by 5 months. This is a serious driving hazard as someone might try to catch the falling visor while driving in sun glare.

    I am having a horrendous noise coming from the MGU untit on the vehicle. This is the part that sits on top of the alternator and is like a mini generator. This part is screeching and making a ton of noise. I have read through forums and it seems like many many people have had the same problem with this part. I think it is time that they re-engineer a new part as this part has been failing for some within the first 5K miles on the vehicle.

    The bolts that connect the two parts of the exhaust pipe, about midway on the truck, sheared off. The truck is a 2021 with only 47,000 miles on. These bolts should not be shearing off like this

    While driving the power steering cuts out and flashes on the dash power steering unavailable, service required. It happens intermittently, but when it happens the steering wheel locks up while driving. I have had it to the Ashland Chrysler dealership, they charged me to say that it happened because it was cold outside. It keeps happening even though it's not cold

    I am submitting this report to alert the NHTSA of potential safety violations and undisclosed structural damage, drivetrain modifications, and possible engine replacement regarding my 2021 RAM 1500, which was purchased from Courtesy Chevrolet after being previously owned by Enterprise Rent-A-Car. Unreported Frame Damage & Structural Repairs Multiple inconsistent and unseen frame welds were discovered, indicating prior accident damage and unreported frame repair. Frame welds do not match factory precision welding, suggesting post-factory reinforcement or structural fixes. Undisclosed Transmission Swap from 8-Speed to 6-Speed According to NHTSA records and the vehicle’s VIN, my RAM 1500 was manufactured with an 8-speed transmission. After purchase, I discovered that the 8-speed had been swapped for an older 6-speed transmission (6HP70), which was never disclosed. This creates potential drivability and safety concerns, as the truck’s ECU may not be calibrated for the correct transmission. Possible Undisclosed Engine Swap The engine in my truck has multiple ink and paint markings, which are commonly seen on replacement engines. RFID engine label does not provide a matching serial number, making it difficult to confirm if the engine is original. The casting number on the engine sticker is inconsistent with the vehicle’s model year and VIN (2021), raising concerns that it may be from an older model. Engine mount bolts and wiring appear disturbed, suggesting prior removal and reinstallation. If my truck has an older or higher-mileage engine, this impacts performance, emissions compliance, warranty status, and safety. Lack of Maintenance Records & Vehicle History Transparency

    The etorque MGU is failing at a high rate, worse in the winter months. Currently, 4500 people waiting for parts with no help from RAM. Trucks are completely out of service.

    Started hearing bearing noise from the eTorque MGU (motor generator Unit) at around 40,000 miles on odometer. Took the vehicle to dealer for problem determination and they confirmed it was a problem with the MGU. I was told a total failure can cause the main electrical fuse to fail without warning leaving the vehicle completely without power in traffic. There is also the possibility of the bearings seizing and the entire pulley shearing off while in operation. Through two different online owner forums, I have verified that this appears to be an increasingly common problem with 2019-2024 models. RAM appears to be aware of this problem as they issued a Technical Service Bulletin on 1/1/2022 (S2208000009) which talks about the bearing noise and underlying problem.
