The truck has done this four times since 01/22/2026. While still moving slowly the truck will do this while going down the highway. One other safety issue was when I merged into traffic on the highway (You have to merge into the fast lane at this location) the truck wouldn't go past 4th gear approximately 40 mph with cars coming up on me at 70. All of these problems correct when I can get the truck restarted.

The contact owns a 2023 Ram 1500. The contact stated that while driving on several occasions at various speeds, the seat belt, ABS, check engine, and other unknown warning lights illuminated. The contact stated that the messages “Service Transmission – Continue in D – Do Not Shift or Turn off Engine until You Reach a Desired Location”, "Service Power Steering", "Service Parking Brake", "Park Sense Temporary Unavailable", "Service Transmission – Continue in D”, and “Do Not Turn off Engine”, “No Buss” were displayed. Additionally, the windshield wipers activated inadvertently. The contact stated that on one occasion, while in the middle of traffic, the vehicle was pulled over to the side of the road and the contact attempted to turn off the vehicle by depressing the ON/OFF button, but the vehicle failed to turn off. After several attempts, the contact was able to turn off the vehicle. The contact turned off and restarted the vehicle several times to reboot the vehicle. When the vehicle was restarted, the vehicle failed to accelerate. The vehicle was towed to a dealer where it was diagnosed that there was an unknown issue with the wiring on the passenger’s side of the vehicle. The vehicle was repaired, but the failure reoccurred 1 year and 7 months later. The vehicle was taken to another dealer where it was diagnosed and determined that the CAN-C network was offline, the OCM was the module taking the bus down, circuit D13 was at 0.37 volts instead of 2.7 volts, and D14 had 0 volts, indicating a ground short. A connector was found in the wiring diagram closer to the OCM that should only have the OCM in it. D14 was rubbed through on the seat frame where it ran down from XY420A. While the technician was removing the wiring harness, the short to ground was no longer present. The rubbed section of the wire was cut out, and a new wire was installed, but the failure reoccurred within 24 hours. The vehicle was taken to the same dealer where it was diagnosed and determined that wiring needed to be resecured. The vehicle was

When slowing down in traffic or approaching a stop sign vehicle will stall then turn off. This will than cause the vehicle to abruptly stop. Emergency brake is then engaged. It takes 1-3 times to engage vehicle to restart using the push start button. This happens with in 2-4 blocks of a cold start or even after 15 minutes or more of driving. This vehicle has been in the Dodge dealer several times with them not able to duplicate problem. This happens several times a month. Have been told by dealer it does NOT show a "code" for them to locate problem. When vehicle stalls it puts emergency brake on and alternator light comes on. After vehicle is re started you must pull over and turn vehicle off for few minutes to get alternator light to turn off. Volume of gas in tank seems to have NO bearing on when this vehicle stalls. This vehicle stalling happens more frequently when outside temperature is 50° and above. Happens more frequently with warmer temperatures

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 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 the inability to properly use the various vehicle drive-modes as driving conditions dictate. 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.

ELECTRICAL SYSTEM

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

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

ELECTRICAL SYSTEM

I own a Ram 1500 Big Horn that has repeatedly shut off while driving and entered limp mode, causing sudden loss of power and engine shaking. This has occurred both while driving and while stopped at intersections, creating a serious safety hazard in traffic. The vehicle has been taken to the dealership more than nine times for the same issue, but they initially claimed they could not diagnose the problem because no codes were present. The vehicle recently broke down again and the dealership retrieved diagnostic codes P2172, C121C00, B151A100, and U100300, indicating airflow and CAN bus communication issues. Ram ordered an alternator to fix the truck, but the first part received was defective and had to be reordered, further delaying repairs. Despite being a loyal customer since 2019, I have repeatedly received substandard service and temporary fixes from Ram, and the truck remains unsafe and unreliable. The problem is unresolved, and I am concerned this defect could cause the vehicle to stall in traffic and potentially lead to an accident.

* 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.

The uconnect 4 system that controls everything on the vehicle will randomly reboot while being driven, disabling safety systems like reverse cameras during the reboot, and leaving the UI for uconnect incomplete after restart is completed so vehicle settings are not available until vehicle has been turned off for over 10 minutes. I believe that this is due to bugged wifi drivers since it seems to reboot when it tries to connect to android auto. I have video of a reboot showing my truck in reverse for exponentially longer than the required two seconds for the camera to come on but it is too large to upload here.

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.

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. The system becomes unpredictable and unstable despite the vehicle being in motion. 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.

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.
