2020 Ram 1500 Electrical System Problems

ABS light keeps coming on and off. The 4WD keeps going on and off and the cruise control and traction keeps working then not working. There is a recall for other year models for the ABS system that basically is exactly what’s happening with my truck. I am worried that it will go out and my truck will stop and cause and accident which almost happened today. This should be a recall alongside those other year models.

In april of 2024 the MGU on the etourqe system needed replacement. The vehicle went into the shop on April 26 2024 and was released to me on may 16 2024. On march 18 2026 the same vehicle was taken to the shop for the same issue. Today is april 8 2026 and the vehicle is still at the dealer with no time frame of repair. No loaner vehicles for me either time, backordered parts all the while I am forced to pay for a rental vehicle. How can there be a known issue but no resources to handle the demand for parts.

When vehicle is subject to hot climates, the media hub will cease to work removing access to phone navigation programs. This can happen mid-drive and cause un-needed distraction. This issue has been ongoing and has been reported to the dealership. The media hub has been replaced also, but the issue continues to happen.

While entering highway- at highway speeds- truck completely lost power luckily we were able to get the burm. Only hazards worked. Truck was not able to be locked or restarted or anything. Truck was towed to dealer and diagnosis is Radio Frequency Hub.

A crack developed in the plastic frame of the rear sliding backlite window, allowing water to enter the vehicle cabin from the rear glass area. Water intrusion has been observed on the rear seating surfaces and interior trim during rain and snow events. The condition has been reproduced multiple times during precipitation and car washes. A dealership inspected the vehicle and performed a sealant repair following manufacturer guidance; however, the water leak persists and the crack remains visible. Water entering the passenger compartment presents potential safety risks, including moisture exposure near electrical components, mold growth, and occupant health concerns. Water has entered the rear seating area where child passengers ride. No warning lights or electronic alerts appeared prior to the condition. The issue appears related to a structural failure of the rear backlite frame seal. The condition remains unresolved and may worsen over time if not properly repaired. The component is available for inspection upon request.

While driving the power plant generator for my engine failed without warning, causing my truck to stop working. There has to be a major issue with the part due to the fact that there is 6000 part back order that has been in going for over 2 years. Someone is going to get seriously injured if this part isn’t recalled and corrected. Having your car shut off at highway speeds is unacceptable. Part number 68623194AC. Ram knows there is a serious issue with this etorque power generator and is not doing anything to resolve the issues, nor making parts available to correct the issue.

While driving my Ram Rebel 2020, the eTorque alternator failed, causing the vehicle to lose electrical power and forcing me to be towed. This posed a serious safety risk, including potential loss of power assist for steering and braking. The issue was addressed only by purchasing a replacement eTorque alternator part through eBay at approximately four times the normal price, because Ram is currently not producing the part. Ram Certified Dealer could not help. Stellantis / Ram customer service has been unhelpful and refused to provide a goodwill reimbursement or solution. I believe this represents a safety defect, as sudden alternator failure can cause stalling and reduce essential safety functions while driving. I am reporting this so that NHTSA can investigate the reliability of the eTorque alternator system and prevent future incidents.

While driving, the engine light turned on and the battery light. Truck started shaking and shut off. Lost complete power. Was right next to my driveway thankfully. Very unsafe situation as I have my wife, [XXX] and [XXX]. Had it towed via my insurance progressive. Mechanic confirmed it was the alternator which is a common problem for the etorque alternator ram rebel 2020. Order is back ordered by over 5,000 customers with no eta of getting the part. Very unsafe situation and now unfixable at this time. There should be accountability with Ram. No recalls have been issued, guidance, or reimbursement via Ram. Help would be greatly appreciated.

My 2020 Ram 1500 Laramie was parked in my garage. I started it to let it warm up before driving. The garage started filling with smoke and the smell of fire. I backed the truck out of the garage and noticed flames on my backup camera. The 7 way plug was on fire. I quickly shut the truck off as soon as I got it out of the garage. I put water on the fire to get it out before it took over the back end of the truck. I had drove the truck the day before and filled it up with gas so my life and my son's life was as risk knowing there is a electrical issue. It also was parked in our garage when it started smoking and it could of burnt the whole garage and house down if I didn't get it out of there as fast as I did and noticed it burning. I had contacted 3 dealer ships and they all said sorry we can't help you. I decided to contact Ram directly to file a claim. Ram told me specifically not to take it to any dealer and they would look into it. 3 weeks later they sent out an investigator to my house. They took pictures of the truck and the damage. They plugged in a code reader and it didn't throw any codes. I asked the guy for the report and he said he couldn't give me one. I have since heard back from Stellantis and their email said things like this happen and they have declined any further assistance associated with this fire. They than said to contact the insurance. A fire is a safety issue and there is major concerns of safety. I don't feel safe when they said it was safe to drive after they did the investigation. I took it to a dealer ship to have it repaired and it started to smoke twice driving it to the dealership.

The contact owns a 2020 Ram 1500. The contact stated that while driving and attempting to stop, the brakes failed to operate as needed. Additionally, while hauling a trailer downhill, the trailer brakes became inoperable, and only the brakes on the vehicle were working as designed. The warning light "Trailer Brakes Disconnected" was displayed on the instrument panel. The vehicle was taken to the dealer, where it was diagnosed but no failure was found. The manufacturer was not notified of the failure. The approximate failure mileage was 105,000.

I own a 2020 Ram 1500 with approximately 61,000 miles. I started noticing a clicking/grinding around the motor area at around 59,000 miles. I brought the truck to a local mechanic, who diagnosed it as a possible alternator issue. He suggested bringing it to RAM service because it may be covered under warranty. I followed up by bringing it to RAM to diagnose the issue. After multiple visits, they could not pinpoint the issue, however recommended replacing the belts and adjusters. Over the course of the next month, the clicking/grinding got louder. I made another appointment with RAM, and while I was on my way over there the truck had catastrophic failure and seized all operations. Thankfully I wasn't going more then 20MPH or else something really bad could have happened. At that time, the truck was reading code U0594, which translates to "Invalid Data Received From Hybrid/EV Powertrain Control Module". I had to get the truck towed to RAM, where they have now had it for about one month. Originally they had said that I would need to buy a new alternator and associated belts/adjustors and battery because i was beyond any standard warranties on the truck, with estimates over what the vehicle is worth, however some personal research found that there is a federal emissions warranty that covers an issue like this. I was fortunate enough to get a loaner car from the dealer two weeks after my truck seized up. I have read online that this is becoming a more common issue with these trucks and feel the manufacturer should raise a warning to their consumers. Had I been on the highway when this happened, who knows where I could be.

RF hub has now failed 3 times in the last 10 months. The last time they replaced the third brake like and now I am having the same issue. Dealership is telling me it’s the back window and that they will not pay for the problem to be fixed. Safety at risk by vehicle breaking down with no transportation on the side of the road. Problem has been confirmed by dealership which led to first repair. No warning prior to failure.

This is a 2020 Ram 1500 3.6L Big Horn. Blinker is constantly on for right turn when blinker arm is in neutral position. The only way to turn it off is to put the blinker arm down as if you are signaling a left turn. As such, I have no left turn signal. This could be dangerous for changing lanes especially on the highway. I have not brought this to a dealer yet and no one has looked at it yet except me. There was/is no warning signal. I have seen recall A2B/NHTSA 24E-082 which identifies two part numbers and also states that similar parts (SCCM) may be affected. I think I have a defective SCCM but there is no recall on my vehicle.

The alternator failed on my vehicle leaving the vehicle without any power in the middle of the interstate roadway having to manually pushed to the side of a very busy highway then towed to a repair shop afterwards. Simply put, my truck just killed in the middle of a interstate very shortly after having a low battery light come on. Speaking with the repair people at the Ram dealership there is no way to repair the alternator and they currently have over 5,000 of these on backorder from them going out in other vehicles with the same alternator. Warning lamps came on the dashboard but only about 30 minutes before the vehicle lost power and was unable to move.

The vehicle had 2 leaks; 1 at the rear cabin window and 1 at the rear brake light. Both of these areas are part of a TSB/class action lawsuit. Water was getting in and caused the module to go bad. The module not working in turn caused the battery to die and because of all the failed attempts and overloading the starter, the starter ended up going out after they started fixing the module.

The etorque generator stopped working, I can’t find the part in any dealership since it’s back ordered with no release date on more than 10,000 parts according to all the dealerships

After hearing a grinding noise coming from the engine, I took the vehicle (2020 RAM 1500 w/5.7L eTorque) to the dealer. It's been waiting for a replacement MGU (Motor Generator Unit) for over 3 weeks but I'm told it might take months to get a replacement part. Fortunately, I discovered this before having a breakdown on a busy highway or up in the mountains. Had that occured, I most certainly would have lost the ability to steer the truck and braking would have been diminished. I'm hoping this manufacturing defect is elevated to safety recall status in the hope of preventing future loss of life.

While driving 55mph my vehicle suddenly lost power, causing traffic behind me to blow their horn, then pass me. Thank god the people behind me didnt crash into me. I drove straight to Mechanics. This happened in mid October 2025. I was told its the e torque generator that needed replaced. My mechanic has ordered it several times just for it to refund him due to being out of stock. I have been in contact with ram over this issue since October. One supervisor even said my part was being expedited to mechanic, just to be told by my mechanic no one has reached out to them. This is now February 2026 and I still have no eta on part. Supervisors are not taking my calls nor returning them. Ram needs held responsible. I am still making monthly payments on a vehicle that I can not drive. It almost seems like a fraud situation with over 3,000 people waiting on a single part with no etas.

The contact owns a 2020 Ram 1500. The contact stated while driving at 20 MPH, the message "Alternator Fault Detected" was displayed. The vehicle lost motive power and came to a complete stop in the middle of the roadway, where the vehicle was unable to restart. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed or repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 40,000.

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.
