    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.

    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.

    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.

Next morning truck started normally with an error message "Power Steering Unavailable". Truck then began to run through a series of "error messages" and windshield wipers turned on and truck would not shutdown, unless you disconnected the battery. Towed to dealership and after several weeks of diagnostics with the manufacturer's assistance (due to the number of errors) it was determined the failure was the Power Steering Module. Once the Power Steering Module was removed, all other modules came back online and functioned normally. Even though the dealership has seen multiple failures of this type, it was not on the recall for this truck. Had this failure happened with my family in the vehicle while driving, it could have had devastating effects...

    I am submitting this complaint regarding a critical issue with my 2021 Ram 1500 equipped with the eTorque mild hybrid system. The vehicle has become inoperable due to the failure of the etorque alternator in this system. Unfortunately, Mopar—the official parts supplier—has not made this part available, and it has been on indefinite backorder for months. This is a known issue and has broken just outside of warranty.

    2021 Ram 1500 Laramie. 2 Occasions of unexpected engine Revving. 1) Pulled up to a stop, waiting for cross traffic, when fully stopped, the Engine began to rev up by ~500 RPM, up then back down, about 3 times in a row. Each time the truck tried to creep forwards, forcing me to step on the brake harder to prevent movement. Each engine surge lasted 1-2 seconds. 2) At low speeds (<20mph), car had similar RPM surges, but just caused some jerking. Both occasions occurred within 2-3 minutes of a cold start (~70 Deg F Env. temp). Certainly a safety concern, needs to be addressed.

    The alternator with the etorque option. Truck is available upon request. Stellantis knows of the issues with the motor and doesn’t have a fix. The part to fix is on back order with no eta till available. I have been researching and some are without a vehicle up to a year. Dealers are aware of the situation. No warnings are shown prior to a total power loss failure. While driving home from work lights all over the dash lighted up and my truck was reading 9 volts. Luckily I was close to home and coasted into the driveway. My truck is now dead in the water sitting in driveway till when a part becomes available. I ended up leasing a car due to having no other option to get to and from work.

  24. Electrical system, Jul 6, 2025

    Component: Motor Generator Unit (MGU) — part of the eTorque system on 2021 Ram 1500. What happened: I own a 2021 Ram 1500 with eTorque. In the year I’ve owned the truck, it has broken down twice due to major electrical issues. Most recently, it has been in the dealership’s shop for over 3 weeks due to a faulty MGU (Motor Generator Unit). There is no estimated time for repair because the part is backordered nationwide. Safety risk: The MGU failure caused the vehicle to become completely inoperable, leaving me without reliable transportation. I am concerned this issue could lead to a loss of power or stalling while driving if it had occurred under different conditions. Reproduction/inspection: The issue has been confirmed by the dealership (Preston Chrysler Dodge Jeep Ram in New Castle, PA). They are unable to proceed with the repair due to lack of part availability. The truck is currently sitting on the lot. Warning lamps/symptoms: Prior to failure, warning lights appeared and the truck experienced erratic behavior. The vehicle would not start after being turned off for a short period of time, and the RF hub had previously failed as well.

  25. Electrical system, Jun 30, 2025

    The MGU of the 2021 Ram Laramie (e-torque) is not functioning properly and hampers the safety of the vehicle. The MGU, which controls the alternator, will not charge the battery beyond 13.0/13.2 volts during driving. As a result, when sitting for several days, the battery will not have sufficient voltage to start the vehicle since it is not charged fully during driving. Additionally, the MGU is now making a strange bearing noise so we will see if a failure is imminent. Considering this MGU controls the starting of the vehicle during stop/start, and the battery is not charging sufficiently to ensure the owner is not stranded, I consider this a significant safety issue (especially when I live in a place with winter of 8 months). I have not seen any warning lamps, but the charging indicator/screen shows 13.0 as below normal.
