2021 Ram 1500: multiple warning lights

Filed Nov 15, 2025 · Electrical · TX

All warning lights on dash came on including battery. Freedom Dodge assessed it on 11-10-2025 and said the vehicle generator has an internal short and is discharging the battery. If being operated could cause the vehicle to die while in motion. I am making $700 per month payments and Freedom indicated over 6000 of these units are on back order and cannot give me a date for replacement only saying "months"

Driving to work and my truck lost all electrical power. All display lights turned on and hazard light signal started blinking but the hazard lights were not actually on. I then lost all electrical power; power steering, hazard lights would not turn on, all dash lights and display lights, head lights at first and then the battery died a couple minutes after that started. I could not put the truck into neutral so I could push it to the shoulder of the highway. I had to put it in Neutral manually with the pull tab under the steering wheel. My Ram 1500 5.7L hemi etorque was towed to Andy Mohr Chrysler Jeep Ram. The service shop told me that the motor generator unit is on back order and it could take a month or 2 months for the part to come in.

My Ram has the ETorque Generator that failed. It has caused the vehicle to suddenly stop and lose power. It first lost all electrical components in the interior. Then driving function shut off which includes the power steering. I was then driving down the street and it suddenly stopped and grinded into the park position of the transmission. The engine bay was very hot and I was surprised a fire didn't start. I hooked up jumper cables to another vehicle to get it off the road way as you couldn't shift it into neutral when the battery was dead. Pretty much all of the warning lights came on as I was still moving and they are still on. I took it into the ram dealer locally and they said there is 4379 that are in the same boat. There is no outlook to get replacement parts. I then took the Etorque generator out and tried having it rebuilt as there was no answer from Ram when it could be fixed. The place I took it to specializes in rebuilding alternators and they were able to fix the bearing problem in the generator but were unable to fix the function of recharging the batteries in the vehicle. So I have to put my truck on a charger every night so its charged up enough to make it to and from work. The vehicle has been inspected by a member of the Fergus Falls Fire Department and he is concerned with constant charging of the battery and electrical issues.

On May 16 2025 I started my truck and all the lights started flashing on my cluster( I took pictures) I drove down the street in my vehicle and it put itself into park. I drove back to my shop and called the dealership to make an appointment along with enterprise Rent-A-Car. I had the rental vehicle from May 16 through May 22. After the ABS module recall was performed on May 21, 2025, my 2021 Ram Rebel began experiencing electrical and mechanical failures affecting multiple vehicle systems. While driving at approximately 7 mph, the vehicle unexpectedly shifted itself into Park. Just like the separate occasion, the parking brake engaged while the vehicle was in motion. These events pose a major safety hazard. Since the recall, the following issues have occurred: •SERVICE BRAKES: Parking brake engaging while driving; ABS-related instability. •POWER TRAIN: Vehicle attempting to shift into Park and 4WD High without input. •ELECTRICAL SYSTEM: Dash lights flicker; HVAC system changes temperature settings on its own (e.g., jumping to 72°F); ongoing parasitic battery draw. •ELECTRONIC STABILITY CONTROL: Loss of system coordination and erratic vehicle behavior. •FUEL/PROPULSION SYSTEM: Sudden drop in fuel range readings (e.g., from 180 miles to 23 miles instantly). •VEHICLE SPEED CONTROL: Unexpected shifting and control changes during low-speed driving. •UNKNOWN OR OTHER: General system instability, rough driving behavior, and degraded performance. I was by the dealership when it went into park so I pulled in. The dealership has acknowledged the update was performed but refuses to inspect the truck until July 8, despite the escalating safety concerns. I believe the ABS module or its software update is causing communication failures across the vehicle’s CAN network, affecting critical systems. This vehicle is not safe to drive in its current condition. I was told because I did not purchase the vehicle at Wilder that I was not eligible for a loaner vehicle.

I was driving and my vehicle make a dinging sound, all the lights on the dash came on and the truck started accelerating on its own. I did not have the cruise control nor was I pressing the accelerator and the truck was accelerating by itself. If i used the brakes the truck would slow down, but when I released the brakes the truck would self accelerate again. If I turned the truck completely off and back on it went away for a couple days but then happened again. This was a super dangerous situation as it was happening suddenly and without warning and I could have easily struck another vehicle or a pedestrian or lost control of my vehicle and wrecked. The issue happened out of no where on its own, was not triggered by anything and could easily cause serious harm to others if this happens to them. The issue has been confirmed and repair by Safford Dodge of Fredericksburg VA. (See attached service invoices) They deemed it a failed connection for acceleration pedal. They replaced it and there has not been an issue since. All of the warning lights and service lights on the dash became lit when this issue started happening.

I was making a right hand turn at about 5-10 mph and the truck stalled. All dash lights were still on. Truck was in Run position, engine just stalled, it put itself in park and emergency brake was engaged. Restarted truck with no warning lights or possible cause of fault. Thankfully there was no traffic or I could’ve been hit.

April 12, 2022 multiple warning lights ( check engine, electronic throttle, etc. ) appeared, screen warning to get to dealer to service. April 13, 2022 visited local dealer, earliest to service April 20, 2022. April 16, 2022 limp mode, restarted vehicle, restored normal operation with warning lights still showing. April 18, 2022, dealer serviced and stated fixed. April 19, 2022, warning lights and limp mode while driving on highway at 70 MPH. Managed to get to side of road in traffic, waited for break, turned around home. April 20, 2022 vehicle to dealer to repair. Still there as of April 28, 2022. "Star Case" opened. All diagnostics failed to locate problem, now trying various inspections / repairs per FCA technical. Dealer advises they have another similar vehicle ( 2021 Jeep Gladiator Eco Diesel ) with exact same situation so this is not one odd vehicle. Further extent of affected vehicles unknown. Safety issue due to vehicle going into limp mode with no warning, causing difficulty driving in traffic, especially at highway speeds, and risk of accident. Dealer and this owner note that all of this happened right after dealer completed recall for exhaust fluid software system. It appears likely that something done with this recall triggered these problems.

The truck just stalls randomly and all lights come on. Then it puts the emergency brake on. You have to put it in park release the the brake and restart it and hope no one hits you. I brought it to the dealer twice so far. I also called Chrysler customer care. I have a case# 82559049. They did nothing for me and I requested to speak to a esupervisor. I haven't heard back. Both times they say no fault codes, they never heard of the problem and cant duplicate. The second time they stated they updated the PCM software and said it happened in the morning with right turns... They now also put electrical and body systems and successfully flashed ECU from old part number to current part number. I never told them anything with right turns. I'm bringing it to the dealer today. They left a part hanging under the seat. The engine also sometimes tics when first started then goes away. I'm very concerned for my safety and if I have any passengers. First time under a 1k miles in May 2021 then randomly since then .Last time March 2022
