ABS module needs replaced. It was recalled in all trucks except for this year model. It is currently on back order and I have been waiting for the part for almost a year! All emergency lights in the dash are on all the time and now when I am driving, the accelerator goes completely dead. It happens randomly and has happened multiple times now. The dealership has accessed this and stated that the ABS module will fix the problem. This is very dangerous and needs to be looked into. Why can’t they fix my truck?

The tensioner pulley seized up causing the serpentine belt to break and taking the MGU E Torque Alternator out. We have learned that there are no MGU parts available and we are one of 4000 waiting with no ETA available. You can’t buy a used one as they can not be reprogrammed to a different truck.

I purchased a brand new 2020 Ram 1500 with 5.7-liter hemi ETORQUE engine in 2020. The vehicle had been making a squealing noise since before 40k miles. Dealership was unable to identify issue on numerous occasions. On 4/8/2024, with vehicle mileage at 74k miles, the noise worsened to a point where the vehicle was not drivable. They identified the "Alternator" (MGU) to the etorque needed to be replaced. The part was on back order and did not arrive until 6/24/2025. At which the dealership replaced the part and expedited the return of the vehicle without proper assurance that the replaced part, fixed the vehicles problem. Less than 375 miles later, a system battery saver came up on the dash. Turning off all electronics in the vehicle including but not limited to A/C and radio. Temps were more than 100 at this time. Within less than 550 miles, the vehicle lost all power and shut off while in the middle of an interstate. I lost my power steering and luckily was able to move onto a narrow shoulder but was left in a very dangerous situation with my family on the side of a high-speed interstate, awaiting a tow truck for hours, without rear end protection. There were a lot of close calls and no urgency from RamCare Stellantis. I was told that the vehicle can only be seen by a certified ram technician. The only certified Ram Dealership that was willing to help was more than 30 minutes away, where the vehicle still sits today. Now the vehicle has been at a dealership since that break down on 7/3/2025. Awaiting another back ordered part, with no estimated eta. This time it is awaiting a 48V Power Pack, related to 8yr/80k mile warranty. I am having to pay out of pocket for a rental, while still paying on a car loan and insurance on a vehicle I have not been able to use since April. Customer service has been horrific handling my case. Leaving myself with no certainty that I will ever see my vehicle again or if the long awaited back ordered part will in fact fix the issue.

There is an issue with the turn signal and apparently all models 2021-beyond have this recall. The right turn signal will not turn on at all, and the left is always on when in neutral. This issue has come and gone but it’s been the case for the last few weeks again.

My 2020 Ram 1500 etorque had a major breakdown. My husband was driving down the highway in a construction zone when he lost power steering, power brakes and then the vehicle totally shut down. He had to steer it to the side of the highway, barely making it. We had the vehicle towed to the dealership who ran diagnostics on it and told us the Mechanical Generator Unit (MGU) needed to be replaced. The major issue: the MGU could not be found anywhere in the US. They wasn't able to order / backorder from anywhere. They said it could take months or longer to get the part. We couldn't go indefinitely without our truck so the dealer recommended we trade it in. That was our only option so that was what we were forced to do. We did not want another vehicle!! Ours was paid off.

Turn signal does not shut off regardless of the position of the turn signal switch. Appears to be an issue with the SSCM. The malfunction makes safe turning/lane-changing impossible. It has been confirmed by the dealership but has not been inspected. There was no forewarning prior to the malfunction and no indication besides the malfunction itself.

The Emission Device 'Active Grill Shutters' have failed for a 2nd time, with a MIL on my perfectly maintained, once at 38K, then again on 9/10/25 @45K mile truck. A Google search leads to likely 100's of other Ram 1500 Owners reporting the same issue and resultant MIL. The prominent cause of the issue appears to be the Electrical Connector. Some reports indicate seriously melted wires, and I assume a fire risk if not corrected. The dealer says it's a $525 repair. Please help me and 100's of others with this serious issue. Also I noticed a Similar Recall Action on Nissan for Active Shutters.

The Engine Generator Kit - Mopar part# (68623194AB) failed which drained the battery and when I stopped at a red light it put me in park and I couldn’t get into gear to move the truck, a tractor trailer almost hit me while sitting in the roadway. If I order this part which is on back order for over a month I will be the 4,601 person this has happened to. I feel this is a recall safety concern. Thank you.

On June 26, 2025 there was heavy thunderstorms throughout our area. I was driving to my office to pick up an item and all of a sudden my dashboard lit up with numerous error messages. I turned the truck off and could not get it to start again. I had to have it towed to the dealership and they cleaned some electrical connectors and returned it to me. My wife picked it up and on the drive home the windshield wipers went off and she also had numerous error messages on the dashboard so we returned it to the dealership. They replaced some modules as they found rust and returned the truck to me. When I went to the dealership to pick it up the truck would not start. They then said there was some corrosion in the star connectors and some moisture behind the radio. They replaced parts and returned it back to me. Since then I have had the truck back and had three more electrical issues with the vehicle. The service technician does not know what the error is and is having trouble pinpointing the problem. Its an electrical issue that they can't figure out. Tomorrow I am returning my truck for the sixth time for the same issue. I do not trust the truck to drive around and have not been able to use it for over 60 days.

Generator/altenator. MGU system. Vehicle was hard to crank at store. After it cranked it seemed fine until I went to pull into traffic. Then it completely died In the middle of the road where I was nearly t boned by a garbage truck. All power was gone. No lights, no radio not a thing worked. After 10 minutes waiting in my wife, it cranked. I was driving home and it started smelling something burning like rubber in the cab. Apparently it was the battery in the back seat over heating. It never crunk again and is now in the shop after being towed. MGU failure and burnt batteries. On back order for months is what I am hearing.

2020 RAM 1500 with a bad MGU (Motor-Generator Unit). Dealer says they have 2 trucks already waiting on the same part since January. There is a massive backlog and Chrysler is not offering anything on when this will be available. It's on an "engineering hold". It will eventually fail in these trucks and render them inoperable. Waiting 8-9 months for a part should never be an option in any scenario. This is also covered under the Federal Emissions Warranty.

RAM has a bad design on MGU's, new ones and old ones are failing, whining, causing engine spudder and no movement at times. Can't purchase one because RAM has them on "Engineering HOLD". Therefore they no they have an issue, not offer a replacement. I have been advised if they become available I'm looking at $2,000 for an alternator. That is insane.

My control knob is not responding to my truck and I cannot open doors or turn it on and it’s asking me for anti theft code all of a sudden. I took it to the dealer and they say alote of trucks are having the same problem. They say It could be the module reader. Now my truck is not reacting to nothing at all.

I am writing to report a serious and dangerous issue with my 2020 Ram 1500. The vehicle has been randomly shutting off while I am driving, often accompanied by a strange acceleration or revving sound just before the engine dies. This has occurred multiple times without warning, creating an extremely unsafe driving situation. The issue happens at random and cannot be easily reproduced on demand, which I understand may make it difficult to diagnose. However, it is important to emphasize that this is a major safety risk that could easily result in a crash or injury.

Parts number 68623194AB, generator kit for alternator. This part went out on my Ram, Ram is backed up for months on this part. There are more than 10,000 vehicles with this problem. Im also being told that the product is not being produced at the moment, which puts my vehicle out of commission until the part arrives.

Replaced the RFH Hub twice in this vehicle do to water damage. 1st time under warranty, the 2nd out of pocket.

Both repair receipts enclosed and a picture of another vehicle they were replacing the seal while picking up my repaired vehicle. Investigation revealed, they use to fix the back siding window seal which cost $1300, but they replaced the Backlit at $25, now I'm on the hook for $1081.71 and change. $936.71, for the repair, $144.00 for the tow, the same spot it was towed from the first time it happen.

There was a griding under the hood and may lights went out. The dealer said my ETORQUE/alternator needed to be replace. That was done approximately 4/10/25 under an extended MO PAR warranty. Since getting the truck back, it has stalled on me 3 separate times, all at red lights. Twice when the 'auto stop' was engaged and then the car lurched forward after the stall had occurred for about 2 seconds, the third time the 'auto stop' was off, and the stall occurred for about 4 seconds, the car rolled backwards even though it was in drive and then it lurched forward and went. Dealership can't replicate the issue so they are telling me can't fix anything. I am very worried that the car will stall on me at another light or on the highway and something very terrible will happen.

So I am driving on the freeway 70mph and I get a message on my dash that says service shifter then every single light on the dash came on and started to make a beeping noise. I pulled over on the side of the freeway and then all the lights dissappear except check engine. I continued to drive to next exit and this time all lights came on again and truck appeared to be shutting off and turning back on while driving, steering wheel got hard to move all while all lights turning on, on dash. I have taken to shop 3 times first time they told me it was battery so I purchased battery and diagnostic fee for 600. Still continued to have issues even after replacing battery. Then they tell me they don't know what's causing this issue and the truck hasn't been fixed. I'll let the truck sit a few days and check engine light is gone and it will drive normal until the issues pops up again. I just don't know what to do about issue and have lost hope nobody seems to know what's causing thr issue. I have videos of this happening multiple times and I show to shops and they are just im awe and can't figure out what is happening. This happened to me yesterday 4/25/25 and while driving the truck started to show all lights on dash and immediately put itself into park while I was driving about 20 mph. Turned the truck off and started it back on again and got the service shifter message and drove home slowly and truck sat in driveway. I've taken in the truck multiple times and nobody seems to know what is causing the issue and I'm tired of spending money things they believe it to be. Any help would be greatly appreciated as we are starting to lose hope on this vehicle and are thinking about letting get repossessed as it's not useful to us if it can't be fixed

MGU failure leading to car battery being completely drained and unable to run until replaced. Started with bearing noise coming from MGU alternator. Then check engine light came on. Before long a low voltage alarm appeared and was able to safely pull over before truck died. Truck is now unable to be driven until replacement of MGU. Dealer has been unable to source part for over a month and could be at least another month before part is ready to come in. Issue appears to be pretty common on 5.7 L Hemi E-torque Ram 1500's as was told part on back order at this time for over 3,000 other customers

They don’t know when they’re gonna be able to get it the part. I called junkyards call other auto parts stores. No one has got it’ I also went in the Mopar website and they also don’t have it

Steering became sluggish, jerky and erratic. Started sounding like the power steering pump was struggling/straining. I put it in the shop and they claim it’s the eps and rack and pinion gone bad. It is being replaced. How unsafe is this at low or highway speed? How many other complaints are there on this same subject and part? 2019 eps was recalled. How do I find out if I have 2019 parts in my 2020. I know sometimes they are interchangeable. I look forward to hearing from you.

Driving down the road, my auto start stop failure light appeared on dash, followed by a check engine light and a battery light. Tried to pull over on the side of the road when I lost all electrical components including power steering, ac, radio etc. the truck slammed itself into park abruptly and turned itself off. I was stranded on the side of the road and nearly got hit by passing cars several times as I was in a curve in the road. After further investigation it has been determined that the bearings inside of the generator (part number: 68623194AB) went out. The part needed to fix the truck is not being made by the supplier and I have been nearly 2 months and counting paying for a truck to sit and look pretty as the truck is completely unusable. One dealership told me this part was on back order for over Five thousand customers.
