2020 Ram 1500 Electrical System

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

My MGU (special name for alternator on Ram E-Torque) went bad. Starts out as grinding noise (no check engine light yet) then shortly after - total failure. Mine has total MGU failure with check engine light on and voltage warning lights to. I have a an appointment on Feb 12 2025 to replace it. They said it’s going to take about 45-90 days for a replacement part. When failure of this part happens the bearings go first, with a possibility of fire risk, in my opinion. Metal grinding on metal creates friction then fire-in my opinion. I researched and talked to some parts managers at ram dealerships. The MGU is a joke. Everyone of them will fail prematurely. Look into this please. There are 5000 MGU units supposedly being produced and shipped out across the country. Those are being shipped out very slowly when available. Nothing fast about these replacements. And lastly, apparently Ram has decided to not make the etorque available on the V8 engines anymore. Only the V6 engines have them.

ETorque alternator failure. Driving down the freeway going 70MPH my truck went into complete shut down mode. Luckily I was in the right lane near an exit and was able to get out of a potential bad accident by breaking down on the freeway. Was told by the dealership and Mopar that this was not covered by any extended warranty and that this would be a $2000 fix with an unknown lead time as the part is on global backorder. I have been without a vehicle Since December 27th. was told 5000 of these parts were released on 2/17 but I would not be getting one of those. Still no line of sight to getting this part to fix my truck. Clearly based on this information and other posts this is a major issue with the ETorque Rams and a recall should be put in place and Mopar and Stellantis need to pay for this and fulfill these backorders ASAP. Being without a vehicle going on 2.5 months with no fix in sight is unacceptable.

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.

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

Suddenly engine light, tps and shifter turned on , I restarted the vehicle and disappeared but later my truck did not start and it is dead

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.

Motor Generator Unit is making a whining noise, confirmed by the dealership that it's a bearing within the unit going bad. Per the dealer the MGU is on national indefinite backorder and from my research have been since at least January. If the MGU goes bad it shuts the vehicle down. Can be very dangerous if driving on a busy interstate or highway to suddenly lose power or possibly strand you on a road in bad weather. The backorder for this item seems to be a reoccuring issue.

The E to alternator quit rear bearing bad was told that the part was on backorder. It’ll be 68 months for part to come in. We need to have a better description on what bearings they use for the alternator.

Vehicle has stalled twice while approaching stop signs, given me a “service start/stop system” light and makes a loud whining noise. These symptoms are caused by a faulty eTorque generator. The generator is on back order for nearly 5000 other customers experiencing issues with the eTorque system. It is extremely unreliable and will cause accidents if the generator breaks and stalls the truck while in motion. A recall should be issued ASAP and Stellantis should be pressured to fulfill the back orders for those experiencing faulty generators.

Truck won't start or move from park new battery was drained in one afternoon. Now vehicle won't start .

Additionally, the vehicle failed to shut off as needed. The failure had occurred on several occasions. There was no warning light illuminated. The vehicle was taken to an independent mechanic where it was discovered that there was an issue with the electrical system; however, the independent mechanic was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 110,000.

The vehicles, multimedia hub fails in hot weather, not allowing connections from the phone for Maps and CarPlay/androidauto. I have had the media hub replaced two times under warranty and the issue never resolves. Public forums show similar complaints from other drivers of the same make and model.

The contact owns a 2020 Ram 1500. The contact stated while driving 25 MPH, the message "Side Mirror Sensors Unavailable - Service Required" was displayed. The infotainment system screen display turned black; the defroster engaged to high temperature while the A/C system became inoperable. Additionally, the contact stated that the windows failed to roll down while engaging the power window switches, and the front driver's side seat was unmovable. The contact stated that the failure recurred intermittently and lasted approximately 5 minutes. The contact stated that she suffered from chronic obstructive pulmonary disease (COPD) and the failure was a significant safety risk. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 51,000.

Left turn signal does not self cancel at times. This is an intermittent problem.
