2023 Ram 1500 Electrical System Problems

Starting March 30 2026- My Dodge Ram 1500 with the digital dashboard statred registering the wrong speed- Which was always higher than the speed I was going, by a lot! It is still happening to today, we will see tomorrow.

2023 Ram 1500 V6 eTorque, 40,000 miles. Two stalling incidents have occurred under different conditions. Incident 1: While towing approximately 4,000 lbs, the 12V battery began slowly draining while the vehicle was in motion. Battery voltage gradually dropped below 10 volts until the engine shut off completely while driving. No warning lights appeared prior to shutdown. Jump start restored normal operation. Stored fault codes retrieved afterward showed 16 simultaneous voltage fault codes across every major module including ECU, ABS, EPS, DDM, PDM, CSWM, IFC, PTS and SCCM — all logging system voltage below allowable range simultaneously, consistent with a complete charging system failure. PCM also logged a U0401 code indicating implausible data received, consistent with the PCM losing stable voltage. Incident 2: After approximately 45 minutes of low-speed driving (5-10 mph) in a Walmart parking lot, the vehicle stalled without warning on a busy road in [XXX] . My wife and two young children were in car seats in the vehicle at the time. The engine cut off completely in live moving traffic with no warning. I was forced to exit the vehicle and jump start it in the middle of traffic while my children remained strapped in their car seats, creating a serious and dangerous situation. Jump start restored normal operation. On the subsequent highway drive home, battery voltage was observed declining from 14V to 13.2V over the course of the drive, suggesting the charging system is unable to maintain adequate voltage output. This is a known recurring issue with the Ram eTorque mild hybrid system. NHTSA has an open preliminary investigation into eTorque stalling on 2022 Ram 1500 models. The MGU, BPCM and PCM are all covered under the 8-year/80,000-mile Federal Emissions Warranty verified via VIN. PCM software updates have never been performed on this vehicle. Vehicle is being brought to an authorized Ram dealership for diagnosis and warranty repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U

* Sudden shutdown while driving * Dash failure * “Vehicle not in park” message * RF hub failure * Recall references While driving at highway speeds and without warning the entire dashboard shut off and the vehicle lost power. The message “Vehicle Not in Park” appeared. My son was forced to coast off the highway to safety. Once the vehicle stopped, it shifted itself into park. The truck restarted briefly but failed again shortly after. Luckily this time he was able to drift into a nearby gas station. At that point the vehicle had no dashboard lights, no ignition response, and no electrical power to the drivetrain, though interior lights still worked. Vehicle would not start and needed to be towed to the dealership where is sat for 12 days before they replaced a water damaged RF hub. There was no cracks or leaks located but there was water damage. Weather conditions: Sunny and dry, temperatures in the mid-50s. This failure created a dangerous situation. While driving at highway speed. This incident placed my sons life and the lives of others on the road in danger. Since this frightening event, we have conducted extensive research and discovered that this appears to be a well-documented issue affecting Dodge Ram trucks, specifically involving moisture entering the cab and damaging the RF hub, which can cause electrical failures and loss of drive power. The dash shutting off and truck losing power while driving — is a major safety issue. Situations like this are known to fall under sudden loss of power / drive power investigations by the National Highway Traffic Safety Administration (NHTSA). I' am requesting a formal investigation into the moisture intrusion issue affecting Ram trucks, consideration for a recall or technical service bulletin addressing this defect and invoice reimbursement.

Etorque and battery failure. Etorque was failing and coldbrook Mitsubishi said it was fine. 2 months later brought to Lee dodge/ram and told etorque bearing gone. By now 80k manufacturer warranty over 80k and not warranted despite me telling them before this mileage. This etorque should be recalled and paid for. This truck has been nothing but problems. I won’t buy anything from stelantis in the future!

The contact owns a 2023 Ram 1500. The contact stated that while driving approximately 6 MPH, the vehicle lost motive power, and the parking brake unexpectedly engaged. The contact manually disengaged the parking brake. The contact was able to restart the vehicle; however, a message to “Shift to Park” was displayed, and the low-battery and low-voltage warning lights were illuminated. The contact stated that the failure persisted after restarting the vehicle. The vehicle was taken to an independent mechanic, but was not diagnosed. The mechanic informed the contact that the battery had not failed but that the vehicle was experiencing voltage errors. The contact was informed that the battery did not need to be replaced, and no repairs were performed. The vehicle was then taken to a dealer, but was not diagnosed; however, the dealer retrieved DTC: P032F. The dealer informed the contact that the failure could not be duplicated, but advised the contact that the battery was failing. The exact cause of the battery failure could not be determined. The dealer replaced the battery. The vehicle was later taken to another dealer, but was not diagnosed or repaired. The contact was informed that the failure could not be duplicated and that the cause of the battery failure could not be identified. The manufacturer was not made aware of the failure. The approximate failure mileage was 7,000.

While driving, the vehicle experienced a sudden loss of electrical voltage. Multiple warning messages appeared, and several vehicle systems disabled while the vehicle was in motion. Power and safety features malfunctioned, and the parking brake engaged unexpectedly. The vehicle became unsafe to operate while driving. The failure required towing and a battery replacement to restore drivability. The battery failure occurred as part of an active charging system malfunction, not a no-start condition. This event created a serious safety risk to the driver and others on the roadway due to loss of vehicle control and disabled safety systems

While driving at roadway speeds, the vehicle experienced a sudden loss of the instrument cluster and infotainment display, immediately followed by an engine shutdown. Steering and braking assistance were reduced during the event, requiring immediate driver intervention to safely maneuver the vehicle. The failure occurred without warning. No prior warning messages or indicators were visible before the loss of power and instrumentation. After the vehicle coasted and was restarted, all systems appeared to return to normal operation. This condition has occurred more than once and presents a serious safety risk, especially at highway speeds, due to loss of engine power and driver information. The vehicle was taken to an authorized dealership and remained there for over three weeks for inspection. The manufacturer was consulted, but the condition could not be duplicated during testing. No repairs were performed, and the vehicle is being released back to the owner with instructions to drive it until the condition occurs again. The issue has not been resolved, and the vehicle remains susceptible to an unexpected shutdown while driving, which could result in a crash or loss of vehicle control.

On approximately September 2024, after a few months of purchasing my vehicle new, the manufacturer installed battery died. This required me to jump it every time I needed to start it over the course of a week. A local dealership replaced it under warranty, though I noticed when I was driving the parasitic drain on the battery would continue. This repair was done through the Berlin City CDJR dealership located in Gorham, New Hampshire. I suspect if I drove long enough, critical systems would not function correctly while driving due to the battery dying. Today, I noticed the same issue arising. The battery died again, presumably from the same parasitic drain, and voltage was sitting around 10 amps. I would approximate that, over the past six months, the hybrid system has not been functioning as normal when I first purchased the vehicle. The trucks display notes why/when auto/start stop doesnt work. Over the past few months it displays that the battery is charging so auto/stop start is disabled, no matter how far/long I drive. It’s concerning to think what may happen if the hybrid system connected to the truck dies. The first time the regular battery died the display noted low voltage. For this most recent incident, it did not.

My 2025 Ram 1500 TRX has recurring safety-related failures of the infotainment system affecting both Uconnect 5 (12” screen) and earlier Uconnect 4 units. These issues are widespread in 2021–2024 Ram TRX and Ram 1500 models and began or worsened after forced over-the-air updates. The primary defect is black-screen failures while driving. When the screen goes black or freezes, the truck loses all functions controlled through the display, including HVAC/defrost, backup camera, vehicle settings, seat controls, and performance gauges. This creates an immediate safety hazard: I cannot adjust climate/defrost, cannot see the required rear-view camera when shifting to reverse, and cannot access key vehicle information. Owners across multiple years consistently report: • Black screens, freezes, and reboots • Loss of HVAC control and dual-zone functions • Backup camera not displaying • Vehicle/Apps tabs failing to open • Uconnect error messages • Smaller, harder-to-read gauges after updates • Wireless CarPlay/Android Auto failures • No option to decline or roll back OTA updates These failures distract the driver, remove access to federally required equipment (rear camera), and eliminate visibility and climate controls that directly affect safe operation. The system becomes unpredictable and unstable despite the vehicle being in motion. My vehicle experiences the same issues, including: [Insert brief personal symptoms: e.g., black screen while driving, loss of HVAC, camera not available, system rebooting, etc.] Because this affects essential safety-related controls and visibility, I believe this is a safety defect in Ram/Stellantis Uconnect 4 and Uconnect 5 systems. I request NHTSA open a defect investigation and require Ram to correct these failures.

As I was driving, my battery light ignited the voltage on my battery continuously went down. I stopped at a stop sign. The engine shut off car completely stopped. Lights were working on dashboard and display screen, but vehicle would not start jumped vehicle as soon as cables were taken off vehicle battery went dead again then all of a sudden it started up again but something is still not right.

My 2023 Ram 1500 TRX has recurring safety-related failures of the infotainment system affecting both Uconnect 5 (12” screen) and earlier Uconnect 4 units. These issues are widespread in 2021–2024 Ram TRX and Ram 1500 models and began for my truck after forced over-the-air updates. The primary defect is black-screen failures while driving. When the screen goes black or freezes, the truck loses all functions controlled through the display, including HVAC/defrost, backup camera, vehicle settings, seat controls, and performance gauges. This creates an immediate safety hazard: I cannot adjust climate/defrost, cannot see the required rear-view camera when shifting to reverse, and cannot access key vehicle information. In my TRX I have experienced screen freezing, inability to access the rear view camera, audio skipping issues, and various pages missing that were previously available. This is not an isolated incident related to my truck as I have seen reports of many other owners sharing issues that started after OTA updates including: • Black screens, freezes, and reboots • Loss of HVAC control and dual-zone functions • Backup camera not displaying • Vehicle/Apps tabs failing to open • Uconnect error messages • Smaller, harder-to-read gauges after updates • Wireless CarPlay/Android Auto failures • No option to decline or roll back OTA updates These failures distract the driver, remove access to federally required equipment (rear camera), and eliminate visibility and climate controls that directly affect safe operation.

I have taken my truck in to the dealership twice already for the same issue and they are telling me they cannot find the issue. My truck would not start, so I replaced the battery. Noticed that the voltage would drop after driving it about 20 miles or so. Normal range is 13.5V. Starting the truck, it starts out at 13.5V but after about 20 miles or so, the voltage would drop to 12.5V. Dealership could not find out why. Engine light is not on but the voltage drops every single time I drive. I bought it with 11 miles on it in June of 2023 and didn't have this issue until September of 2025. The truck only had about 37,400 miles on it when it started messing up. I am scared/worried that the truck will just stop while driving. I have read many forums and stories about many others are having this issue too. The Motor Generator Unit (MGU) malfunctioning. There are recalls for 2019-2022 MGU but not for 2023 or later.

experienced the exact same failure mode as Ram Recall 24V-729 and my truck and model year fall into the affected vehicle models however my VIN # was not included in the recall. My blinkers do not work as exactly described in 24V-729 and Ram refuses to take financial responsibility of this known issue and make me pay for this safety concern especially when its a known safety recall this year and model truck.

Driving down the freeway, with no previous issues at 80MPH. Next thing the truck stalls and won't restart. Vehicle jumped and runs when connected stops immediately once unjumped. Replaced battery at 51,000 miles and vehicle runs fine. Concern is the alternator is not strong enough to power the vehicle if the battery dies for mysterious reasons.

My 2023 Ram 1500 TRX has recurring safety-related failures of the infotainment system affecting the Uconnect 5 (12” screen). These issues are widespread in 2021–2024 Ram TRX and Ram 1500 models and began or worsened after forced over-the-air updates. The primary defect is black-screen failures while driving and loud screeching noises coming from the radio. When the screen goes black or freezes, the truck loses all functions controlled through the display, including HVAC/defrost, backup camera, vehicle settings, seat controls, and performance gauges. This creates an immediate safety hazard: I cannot adjust climate/defrost, cannot see the required rear-view camera when shifting to reverse, and cannot access key vehicle information. The loud screeching noise causes you to immediately pull the vehicle over to turn off the truck or manually reset the radio. Owners across multiple years consistently report: • Black screens, freezes, and reboots • Loss of HVAC control and dual-zone functions • Backup camera not displaying • Vehicle/Apps tabs failing to open • Uconnect error messages • Smaller, harder-to-read gauges after updates • Wireless CarPlay/Android Auto failures • No option to decline or roll back OTA updates These failures distract the driver, remove access to federally required equipment (rear camera), and eliminate visibility and climate controls that directly affect safe operation.

I request NHTSA open a defect investigation and require Ram to correct these failures. Ram has known of these issues reported to RamCares for months and have yet to correct it.

The dash board showed the (A)auto start stop amd the (P) parking brake after hitting a puddle in rain. I brought the vehicle into the dealership for service on 4/18/2025 . They replaced the right rear caliper and EPB actuator and it temporarily fixed it. The lights still came on but would go off in rainy conditions. They came back on and didn’t go off so I brought it back to the dealership in again on 3/2/2026. First said they would fix the same part now after having my truck for 2 weeks claim it’s not the parking brake actuator but the main wiring harness and refuse to fix it under warranty of their work. I am now told by them they have to replace the entire wiring harness on my expense. Called customer support at ram truck and still haven’t heard back if they would do anything

Ram released a software update to the Uconnect system, and it has disabled navigation, drive mode, and rear camera. This has been nonfunctional now since April so about eight months and they are saying they’re not releasing any new software updates at this time to fix it. I’ve taken it to the dealer and they also cannot fix until there’s a software update from RAM.
