The star connector on the CAN C BUS will start to have communication problems with the all the systems on that star connector approximately after about 15 to 20 min after driving. Systems that were constantly going in and out were the front and rear parking sense, ABS and traction would go out. Service shifter message, caused the transmission to up shift while driving at a constant speed. After getting a check engine light, I hooked up my code reader and had a code for the park sense control module. I proceeded to replace that module and was unable to get the code to go away. Upon further investigation, I found a history code for the CAN C BUS PERFORMANCE code and researched on this topic in the forums with other owners of the same truck and looked for any maintenance for this topic as well. These owners would have the same problem that my truck was having and the dealerships were unable to pin point the malfunction of all these systems. I did find video of an owner that had the same problem as my truck and he was able to pin point the problem down to the star connectors. The star connector would slowly over time while the vehicle was on would slowly take on more power then it was supposed to and overload the star connector. Upon learning about the star connectors, I learned how to replace them and after I replaced the star connectors for the exterior and interior components of the vehicle, everything went back to normal. I do still have the star connectors that were taken out incase I wanted to get them tested for the same issue the other guy found out

While driving the freeway at 70 mph, the truck flashed a message to service shifter. Windshield wipers starting going on their own, all messages popped up on dashboard, and the vehicle started gradually slowing down posing a safety issue. Speedometer was going from 0-50 mph back and forth and steering wheel was hard to maneuver. I was able to get off the freeway and into the frontage safely. However, turning the vehicle was a hassle and even more so when I tried to drive in to a parking lot to get to a safer area since the truck wouldn-??t respond to the gas pedal nor would the steering wheel cooperate. If I wanted to turn it left it jerked on its own to the right. Vehicle shut off on its own and wouldn-??t power back on after that. Tow truck had to be called and was told this was a cause of rfh by rear window(shortage caused by leak on third brake light) this happened after it being repaired. Truck was in shop for over two weeks. Today I-??m being told it is the rack and pinion system causing this shortage and issue. Awaiting repair quote for that

The -??alternator-?? is failing on these pickups. The Dodge Mopar says it-??s back ordered by 5,000 units of these! 5,000! And have no date to tell you when it will be available. As I scour the internet, 1000-??s of people are stranded with almost new pickups, with no way to fix them. We are one of them. I don-??t understand how Dodge can be trusted.

My 2019 Ram 1500 Laramie truck started throwing a check engine light recently while also occasionally being put into "battery saver mode". I went to the dealership to have it checked. The issue is a malfunctioning alternator / generator unit (Mobile Generator Unit) which is a key component of the eTorque system. The dealer said the repair protocol is to replace the MGU. The problem is that there are literally no parts available in the US with no known ETA. The best approximation is 6 months or more. The waitlist is literally more than 3,000 customers. There is clearly a problem with the part and it seems like they aren't currently producing any more which is growing the problem. So, I'm now left with a very bad option - continue driving the truck and risk the MGU failing at any point and causing a serious accident. I have been in a vehicle on the highway when the alternator fails and all electrical systems shut down. It was terrifying for me and my family and we were very fortunate to avoid injury. My other options are to either not drive the truck and wait (not a viable option) or be forced to sell the truck which I would rather not do since it's fully paid off and should go many more miles.

04.22.25- back to back stalls on left hand turns within a 1 mile trip First stall landed me in a ditch less than foot from an oak tree. Coasted a bit before a sudden stop. Second stall allowed me to make it to side street before it abruptly stopped. Prior drive previous day had no issues and no warning lights.

This is the second random stall event for this vehicle. 2019 Ram 1500 with 33,300 miles. Yesterday, 4 /18/25, while taking a left turn from a parking lot at low speed, the vehicle lost all power. I was able to coast to the side of the street. Put the vehicle in park, waited approximately 1 minute, vehicle restarted and seemed to run fine. The first time it stalled it was towed to the dealer and since they could find no stored faults, there was nothing they could do.

While driving down a curving mountain highway above 70 mph, the gauge cluster displayed -??shift to park-?? or -??shift to drive-?? I don-??t recall exactly. The transmission then downshifted dramatically, perhaps into 3rd gear, then the motor shut off.Thankfully, I successfully merged through heavy traffic to the narrow shoulder but the truck would not restart. After over 30 minutes of attempts (fuel tank above half)I called a tow truck. My family climbed up the hill to get a safe distance from the road. It was cold and dark and things could have gone much worse. Ram owners on internet forums have described this exact problem many times and it-??s clear that this is a wide spread safety issue. This is the second time the truck had lost power while driving in the same manner. The first time the dealer could not replicate the issue while it was under warranty and returned it to service. No I-??m out of warranty, need a new transmission at largely my own expense and there are zero available in the country. The dealer has my truck for an -??indefinite-?? time period.

My alternator went out driving down the interstate. No indication that it was bad up until it died. Has been sitting at a dealership for about a month due to this particular part having almost 3000 on back order.

While taking a right turn into a busy intersection, vehicle lost all power and dash lights lit up indicating to put the vehicle in park. I put the vehicle in park and attempted to restart it. The vehicle starter cranked but did not start. I was able to roll the truck back by using the manual transmission release to get out of traffic. I disconnected the battery and waited approximately 5 minutes, reconnected battery, vehicle would start momentarily then stall. Had vehicle towed to dealership where they were able to start it and found no issue.

The truck has stuttered since I bought it when downshifting when cold. Sometimes when it sputters during a downshift it will display the message -??ship to p and select gear-??. Meaning the vehicle has shifted from drive on its own. The only way to engage drive is to stop and select drive. This has happened on the freeway a couple of times and the dealer says they cannot isolate the issue.

- Riverside, CA, USA

The alternator bearing is failing. Stellantis no longer has a supplier to order new alternators from. There is no option to replace this part. The vehicle is 5 years old. I feel this is a safety concern because if and when I eventually lose all electrical power, my passengers and me will be in an uncontrollable vehicle or, best case, a broke down vehicle on the side of the road.

I Have only had this truck for 2 months. I was driving and making a turn and the electrical power steering stopped working and the steering wheel locked. I almost crashed and drove into a ditch with my whole family in the truck. Including a [XXX]. I had to slam on the breaks and barely able to keep the truck from crashing. Dashboard said " Power Steering unavailable Service Required". I turned off the truck and restarted it to see if it would fix the issue. It did not. I drove the rest of the way home going slow with the hazard lights on. Steering wheel needed to be muscled for it to make the smallest turn. I had to drive over curbs because it would have been impossible to make some of the turns needed to get home. I called Ram and reposted the incident. They did not care because my vin is not listed for the recall and that the recall is "VIN specific". I do not understand this. VIN specific means each truck would be custom made and all different. Why is my family's life being risked and not being taken seriously. Once home, I have not been back in the truck. I turned it on the next day and the alert is gone and the wheel moves again. A family of 5 is now at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

MY 2019 RAM 1500 CLASSIC SLT CREW CAB, has a serious safety DEFECT of a Remote Frequency (RF) hub, a critical component responsible for recognizing the key fob and enabling the vehicle to start which won't allow fob to work or remote start. This is caused by the rear light back window has a recurring leak that has resulted in water intrusion into the vehicle. This water damage led to the failure of the Remote Frequency (RF) hub, a critical component. The issue has also resulted in corrosion to wiring harnesses and electrical components. The vehicle is available for inspection upon request. This issue has put mine and my wife's safety at risk on multiple occasions. The vehicle has repeatedly failed to recognize the key fob, rendering it completely inoperable as well as the remote starter. I've been left stranded multiple times due to this defect causing keyfob to not work not allowing me to enter the vehicle either when needed especially when my wife is alone at night in this vehicle. Additionally, electrical failures pose a fire hazard and could potentially affect other critical systems while the vehicle is in operation. There are thousands of ram truck owners also complaining of the exact same issue. I have incurred expenses such as tow fee's and shop fee's when we can't enter the vehicle when posing only the fob on our person and diagnostics of this issue. THIS NEEDS TO BE RECALLED AS THIS IS A MAJOR SAFETY CONCERN

The backlite window on my 2019 RAM 1500 Laramie (VIN: KN655467) has a recurring leak that has resulted in water intrusion into the vehicle. This water damage led to the failure of the Remote Frequency (RF) hub, a critical component responsible for recognizing the key fob and enabling the vehicle to start. The issue has also resulted in corrosion to wiring harnesses and electrical components. The vehicle is available for inspection upon request. This issue has put my safety at risk on multiple occasions. The vehicle has repeatedly failed to recognize the key fob, rendering it completely inoperable. On two separate occasions, I was left stranded and had to have the vehicle towed. Additionally, electrical failures pose a fire hazard and could potentially affect other critical systems while the vehicle is in operation. The issue has been confirmed and reproduced by the authorized RAM dealership. The dealership determined that water intrusion from the backlite window caused the failure of the RF hub and other electrical components. Despite this, RAM/Stellantis has refused to replace the backlite window under warranty, only applying a temporary sealant fix that has repeatedly failed. The vehicle has been inspected by RAM dealership technicians multiple times. Each time, the dealership has confirmed water intrusion as the source of electrical failures. RAM/Stellantis has been made aware of the issue but refuses to properly address it. There were no warning lamps or messages before the initial failure. The first symptom appeared when the vehicle failed to recognize the key fob and would not start in November 2024. After the RF hub replacement, the issue reoccurred, requiring additional repairs.

When I get in my truck I have to wait for a long period of time before my steering wheel will unlock. After it unlocks it drives good. It-??s just take 30-45 mins for the steering to unlock before I can drive it.

I am experiencing an Antilock Braking System ('ABS') control module software malfunction that disables the Electronic Stability Control ('ESC') system. Last fall Sept 2024 was the first incident. I was driving back one night to my cabin construction project in Somerset, PA. It rained earlier in the day and everything was wet. I was almost back to the site, my dash lights started wildly flashing. The ESC SYSTEM OFF displayed, the (ABS) light illuminated along with SERVICE THE ANTILOCK BRAKE SYSTEM. The front passenger side tire started to shake, just as I was trying to avoid a large pothole around a bend. My truck slid straight across it and slammed my front end down in the ditch. I had NO CONTROL. It caused my side airbags to deploy and the seatbelts to lock up. I drove out of the ditch, the truck was ok. I was close so i drove to the cabin. The next morning I inspected everything, in addition: the front bumper was bent, fog light hanging, wheel well was bent, and there were a lot of scratches. I am a small business owner, I didn't want my insurance to go up, and was waiting until I could afford to fix it. The latest incidents were during the last two weeks. First, I was driving on a 70 MPH highway, suddenly service air pressure system displayed and passenger tire pressure went to -??0-??, the ABS and ESC warnings displayed, and that tire started shaking. I pulled over to check the tire thinking I had a flat, but it was fully inflated. I turned off the truck, waited 5 mins then started it back up, "fixed" then drove home. Since then, the truck is randomly locking that brake, while I'm driving. THREE separate times it has locked up. I thought I was dragging something one day as I was backing up. Next day I was backing out of my driveway quickly and it caused me to slide into the road. I test drove away slowly, seemed fine. I went through the three stop signs to get out of my plan. It locked up at the third stop sign, as i turned right almost threw me into the sign.
