The MGU (motor generator Unit) is failing. Appears to be a known issue with Chrysler. Problem is that this part is not available. Was told that there are over 3,000 backordered parts with no eta. The dealer said that they had several on backorder from May. This is a 2019 product and there is no reason that this part should not be available.

The contact owns a 2019 Ram 1500. The contact stated that while driving at 35 MPH, the vehicle jerked violently and downshifted unintendedly. Several unknown warning lights were illuminated, and the gear shift indicator and speedometer were malfunctioning. The contact was able to pull over to the side of the road. The contact stated that the failure had recurred while driving at various speeds, and the vehicle stalled on several occasions. The contact was able to pull over to the side of the road. The vehicle was able to be restarted after 5-15 minutes. The vehicle was taken to the dealer, where it was diagnosed with loose wires. The vehicle was repaired; however, the failure recurred. The contact stated that while his son was driving 65 MPH, the failure recurred, and the vehicle shut off. The contact's son was able to pull over to the side of the road. The contact’s son was unable to remove the ignition key when the vehicle shut off. The vehicle was taken to the dealer several times, but the cause of the failure could not be determined. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the dealer for assistance. The failure mileage was approximately 16,000.
After coming to a rolling stop and making a right, I would attempt to accelerate. The vehicle would then throw itself out of gear and I could not accelerate. A message would appear on the dash "Shift to P then Desired Gear." The problem would not be fixed until the vehicle was put in park, then back into drive. I took the vehicle to RAM and they could not replicate the issue, but it would happen to me regularly (1-2 times a month at random). I told this to RAM Dealership and RAM Cares, but nobody seemed bothered that it could get people killed. The problem did not seem to get fixed until I took apart the throttle body and cleaned it out by hand. Since then, I had not had an issue.
The contact owns a 2019 Ram 1500. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated on the instrument panel. The contact pulled over to the shoulder of the roadway and turned off the vehicle. While attempting to restart the vehicle, the vehicle failed to immediately restart, and several attempts were needed to start the vehicle. The vehicle then returned to normal functionality, but the failure became a regular occurrence. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The contact was informed that the failure had been referred to an engineer with the manufacturer. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 45,000.
Mopar Part # 68623194AB Generator on a national backorder. There is a problem with this part and MOPAR cannot fix the issue - ETA is non existent - Truck has been parked since July 4. Making payments on a truck that is not functioning. The vehicle shut down completely on I-95. Had to have it towed to my home.
At about 77k miles, I started hearing a humming noise from the engine when I would accelerate and then decelerate. Upon inspection and confirmation from Ram dealership, the Engine Generator Kit (alternator) appeared to have a bad bearing and needed to be replaced. I initially agreed to the replacement until I was told that the part needed is on backorder and that there were roughly 4k orders placed ahead of mine nationally. This means I have no way of fixing this issue using an original MOPAR part. I was told I can agree to pay for the item to get the order placed and then wait until it comes in with no timeframe given other than it could be weeks or months. I am now having to drive around in a vehicle that could potentially breakdown at any time and thus leaving me with no vehicle. I do not have any warning lights on the dash but it seems like I am driving a ticking timebomb.
The alternator part has been out of stock since the beginning of 2025 my trucks alternator went out in March and have not been able to find the part available for purchase, it has been 5 months.
The truck lost power steering due to the soldering on the star connecting being messed up. The truck also had 4x4 not available,as well as no brake assist in reverse due to the communication issue. The dealership had to replace the star connector due to soldering issue.
The contact owns a 2019 Ram 1500. The contact stated that while his wife was driving at an undisclosed speed, the left turn signal failed to engage as intended. Additionally, the contact stated that the instrument panel displayed that the right turn signal had engaged independently while driving. The vehicle was taken to an independent mechanic, where it was diagnosed that the steering wheel module had failed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.
The "Generator Kit" which houses the vehicles alternator went bad. I have been waiting for more than 4 weeks for the repair to be done and the shop has no idea when the part will arrive. It is Generator Kit #68623194AB. I reached directly out to 12 dealers and none of them give me any idea of when they can get the part and have a waiting list themselves. The web is lighting up with thousands of complaints about this single issue. One dealer said they have no idea when the part will show up and they've already been waiting for "6" MONTHS. They said it could honestly be another 6 months. For an alternator??? RAM Trucks has a major issue here and they have known about it for a while.
When using reverse, the image stays on the screen in reverse for sometime. also, screen stays a solid color in black or blue at times not allowing any controls on the screen when attempting. Screen will sometimes freeze and reset sometime after driving. radio and or screen stays on for an extended period of time after turning vehicle off leaving vehicle and locking doors still allowing radio/screen to continue in operation.
2019 1500 5.7 e-torque w/58,000. Bearing noise started a few hundred miles ago, waiting for replacement
[XXX] Known issue in 5th Gen Ram 1500s. Defective Mopar Connector Cam Buss. Causes the truck shifting problems and can cause going into park while driving. Issue below is on the forum causing a wreck. My 2019 Dodge Ram Limited started malfunctioning, causing me to wreck when the shifter unexpectedly went into park while I was driving. The brakes locked up, making the truck slide, and by the time it switched back, I was already sliding off the road. Parksense unavailable warning & service Shifter lights do come on. I called the Murfreesboro Ram dealer and they confirmed the issue that is was known to dealers. Majority of the dealers are sold out of the part due to this issue. Charging $200 in labor for a simple 10 min swap out of electrical part. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Rear window seal has allowed water in to the cab of the truck and the electronic components under the back seat have already had to be replaced causing the vehicle to not operate properly. The rear window is still leaking and has leaked since 2021, when it was replaced under warranty. If water enters into the electronic components under the back seat or the air bags located in the head liner, while driving, this could cause severe damage to property and could be harmful to life.
E torque alternator generator failure, loss of power while driving to all vehicle electrical systems. Part is on national backorder. Reading forums this has been an issue with ram on failure and backorder issues for over a year.
The alternator failed suddenly and without warning, leaving me stranded on a road with no shoulder during 91°F heat. The vehicle lost electrical power and required a tow. This is not just a standard alternator,it’s a component of the eTorque mild hybrid system and requires both a specific part and a dealer reprogramming (flash) to function. After the incident, I learned that the part is on national backorder with more than 4,000 vehicles waiting, according to multiple dealers and service centers I’ve contacted. Ram has provided no reliable ETA, loaner, or support option. This is a critical failure that completely disables the vehicle and creates a dangerous safety situation, especially in high temperatures or in areas where pulling over safely is not an option. I was without air conditioning or any form of engine power while exposed to traffic and heat, and had to wait a prolonged time for a tow. This appears to be a widespread issue with Ram eTorque vehicles, particularly the alternator/starter-generator assembly. The required flash must be performed by a dealer, so no aftermarket or independent fix is currently viable. Ram has not issued a recall or taken accountability for this dangerous and increasingly common failure. I am filing this report to request investigation into the failure rate of these eTorque alternators, the supply chain delays that make timely repairs impossible, and the complete lack of contingency support or guidance for affected customers.
I was at a stop light and I got a warning light and a check engine light that said service shifter. After that, it wouldn’t shift gears and I was stuck in 1st gear. I pulled over and got a service tire pressure light, 4WD temporary unavailable light, service airbag light, ESC light, parking light. The vehicle was also sputtering and the cooling fan came on full force.
Our screen turns black, the heat is activated and the windows lock. Dash notifications for ABS flash along with others including blind spot notifications. This occurs while driving. This is a major distraction and concern.
The PCM has completely shut down, the truck has 50k miles, has been serviced regularly, and is in excellent condition. 2021 and newer models have been recalled due to the same issue but not 2019.
The MGU has failed. The truck is undriveable. It was diagnosed by Ram dealership.
Truck was stopped. Then as I started pressing on the gas pedal, there was a warning sound. The gear selector knob rotated on its own from D to P and the message on the screen said to start / stop the vehicle to put it back in gear D. This put myself and my family at risk of a car accident as we were merging onto an expressway. This happened while the truck was starting to accelerate. This is the second time this happens.
What component or system failed or malfunctioned, and is it available for inspection upon request? -The issue involved the truck’s parking and collision avoidance systems, which suddenly shut off. A warning message appeared on the dashboard stating "Service Shifter." This issue may be related to the electronic shifter module or associated control systems. The vehicle is currently available for inspection upon request. How was your safety or the safety of others put at risk? -The sudden deactivation of both the parking and collision systems while the vehicle was in motion created a serious safety hazard. Without collision avoidance functionality and the ability to securely park the vehicle, there was increased risk of unintentional vehicle movement or inability to avoid obstacles, which could have led to a crash or injury. Has the problem been reproduced or confirmed by a dealer or independent service center? -Yes, the truck was taken to an authorized dealer for assessment, and the issue was confirmed. Diagnostic tests found trouble codes starting with "U", which typically indicate a communication or control module fault within the vehicle’s network. The codes provided from the dealer are U0159, U0140, U0100, U0137, U0102, U10121, and U0101. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -The issue has been inspected and documented by the dealership. There is no indication that police or insurance representatives have inspected it at this time, but the incident and diagnostics are recorded in the dealer’s service records. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -Yes, a warning message "Service Shifter" appeared on the dashboard. This message coincided with the shutdown of the parking and collision systems. These symptoms appeared suddenly and without prior warning during regular vehicle operation.
Driving 60mph in 8th gear while raining, 40 deg F, in Minnesota. The truck shut off (I did not press the Start/Stop button) and dash said "Vehicle Not in Park." Went to pull over, put on turn signals, but they didn't work (it acted like the vehicle was completely shut off but was still rolling at 50+ mph in 8th gear - there was no indication on the dash that showed green light indicating turn signal was working). I suspect brake lights also did not work at this time, but cannot confirm because I couldn't see them. I pulled over to shoulder, slowed to a stop, and put vehicle into Park manually. Pressed Stop/Start button and vehicle started. No codes were thrown. Drove another 2-3 miles and similar issue happened again. Display flashed on and off (then completely turned off) when coming to a stop this time. Vehicle stayed running but again said "Vehicle Not in Park" on dash. No other indication on dash (no warning lights). Drove vehicle back to dealership to get inspected. Similar issue occurred 4 more times on the 12 mile drive to dealership. When I got the vehicle into the service shop, I put it into Park, then pressed the Start/Stop button, but the truck would not shut off. I left the vehicle with the dealer and they are currently diagnosing the issue. 105,000 miles on vehicle. First time this issue has ever occurred on the Ram since I bought it used with 67,000 miles on it. Scared the heck out of me - I had cars swerve around me as I pulled off to the shoulder without any indication - no brake lights (I assume), no turn signals. Very scary. I am worried about driving my family (wife and 2 young children) in this vehicle. What has scared me even more is I looked up this issue online and I have found 100s of examples in the forums of similar (or exactly the same) issue happening to them! I have had all recalls completed on my truck and keep meticulous care of it. I am an engineer and understand technical details well - this electrical issue scares me. Not safe.
I took my truck into my mechanic for a loud whining noise coming from my engine bay. I was told my alternator is going out. I have a 2019 ram 1500 5.7L v8 with the e-torque system. Part number 68438054AB or 68623194AB. This part you can literally buy from no one. Not a dodge dealership, mopar or any other website. There is about 1 listing I saw for a used one which was $1000 over what a new one would cost. If this part goes out I’m fully unable to use my truck which has 56,000 miles and is my only means of transportation. I have absolutely no chance of buying this part from anyone or anywhere at this current time. I can barely afford to buy the part even if it was available and I surely can’t afford to pay for a rental car or another car in the time it would take for this part to become available (if it does). From reading online and hearing what the Dodge dealership told me there is about 4,000+ people waiting for this same part. I still am paying a loan for this truck and I am at a loss on what to do. Insurance won’t do anything, dealership won’t do anything, and my bank won’t do anything.
I am filing a formal complaint regarding a critical safety defect in my 2019 Ram eTorque, which posed a severe risk to my pregnant wife while she was driving. The vehicle’s battery unexpectedly failed, resulting in a complete loss of power steering and all safety functions, creating a hazardous situation in the middle of the roadway that could have led to a serious accident. This defect is not isolated. My truck has been at the repair shop for over two months, as the necessary replacement part is on backorder due to over 3,000 reported vehicles affected by the same issue. The widespread nature of this defect and the unavailability of parts amplify the risk of injury or fatality to drivers and passengers. I urge the Safety Advisory Board to investigate this defect urgently, focusing on the significant safety implications and the high number of affected vehicles. Immediate action is needed to prevent potential harm.
The contact owns a 2019 Ram 1500. The contact stated that upon starting the vehicle, there was an abnormal ticking sound coming from the engine, with a message that the "Fuel/Air Ration Imbalance" was displayed. The vehicle was taken to an independent mechanic, where the contact was informed that the rocker arm bearings and lifters needed to be replaced. In addition, the contact stated that while driving at various speeds, several warning lights were illuminated. The contact stated that the windshield wipers activated independently, the power steering assist had failed, and the vehicle failed to stop while depressing the brake pedal. The contact stated that the vehicle went into LIMP Mode, with the "Service Transmission, Continue to Drive, “Do not Shift or Turn off Engine,” and "No Buss" messages were displayed on the instrument panel. The contact initially inspected the vehicle and determined that the battery, relays, and fuses were all satisfactory. The vehicle was taken back to the independent mechanic, where the contact was informed that the vehicle had either a faulty ground wire or a computer. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 43,000.
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
