    While I was driving on the freeway, my check engine light came on and my battery voltage dropped rapidly (within 5 minutes I had a dead battery). My transmission, power train and electrical components all stopped working. Luckily I was pulling over before this happened so I didn’t get in a wreck on the freeway. I had a tow company take my vehicle to the dealer for inspection. After a few days they let me know it was the alternator inverter which was not functioning correctly and caused my battery to drain along with all my electrical components malfunctioning and engine stalling. The dealer has now had my truck for weeks and won’t let me drive it until they resolve the issue with a new inverter which is on back order with no updates on arrival.

    While slowing down to stop at a stop sign the engine shut off on its own. Dash showed message to shift into park once the vehicle stopped. Parking brake also engaged on its own. After shifting into park, restarting the truck, and disengaging the parking brake I shifted back into drive but the vehicle wouldn't move. I shifted into reverse and it would go backwards. Shifted back into drive and it worked properly. It's not safe to have the engine just shut off while you are driving. Also having to put vehicle into reverse before getting it to go into drive is unsafe on a crowded road with vehicles behind you.

    2x within the same week after leaving a stop light/stop sign after the vehicle turns back on and starts to move forward it shuts off completely in the intersection and I had to wait for it to reset before it could be turned back on. Cars had to swerve around me to avoid hitting me. Took to RAM service and they stated a leak behind 3rd brake light got water into a RHF module. Was told after that 2 more trucks with same equipment were brought in for the same thing.

    I was driving and the engine stalled just like I shut it off . I pulled off the road and restarted the engine to have it do the same thing several more times. No codes no warning lights.

    The tailgate has opened on its own twice in the last 6-8 months. This puts a risk for other vehicles if it were to open randomly. To my knowledge this was supposed to not happen after recall 22V904000. This vehicle has not been inspected since seeing this issue and no warning lights happened when this occurred, one specifically had been closed for around 24 hours then randomly opened after car had not been driven.

    The rear window (backlite) has a known manufacturing defect that allows water intrusion, potentially damaging the RF hub and creating conditions conducive to mold growth (see TSB 23-098-23). My vehicle has been affected by this defect, yet FCA has only extended the warranty to select vehicles, excluding others of the same year, make, and model that are clearly impacted by the same issue. This defect has led to saturated floor boards/carpet under the rear seats and has lead to the growth of mold.

    On 3/6/25 at 0520 hours, I 95 northbound in Stafford, VA. at mile marker 141 in left travel lane at approximately 75 mph the truck suddenly lost power slowing significantly. We pulled over onto the left shoulder as the truck slowed and stopped. The truck required shutting off the ignition and restarting the vehicle for it to operable. We had vehicles behind us slamming on brakes and quickly changing lanes in order to avoid hitting us. This truck has been checked by a dodge dealership for previous complaints of this occurring at lower speeds. Dodge dealership told us, there are no codes, no recalls ( only on V8) , we can note it in file but there is nothing else we can do. This is unacceptable and almost got us into a serious accident. There is something wrong with the etorque.
