The contact owns a 2025 Ram 1500. The contact received notification of the federal safety agency Campaign Number: 26V059000 (Exterior Lighting, Electrical System); however, the part to do the recall repair was not yet available. The local dealer was made aware of the recall and informed the contact that parts were limited. The contact was informed that new vehicles were the priority before the vehicles that were already sold. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while idling at an intersection, the vehicle shut off without warning. The vehicle was towed to the dealer, and the battery was replaced. Soon after the repair, while driving 75 MPH, the Forward Collision Avoidance system activated erroneously, and the transmission unexpectedly downshifted. The contact attempted to take the vehicle for service, but was unable to contact a dealer. The manufacturer was made aware of the issue. The vehicle was not repaired. The failure mileage was approximately 30,000.

I was only allowed 3 components to choose from, but I want to make certain that Im including the these additional components that has been failing:Forward Collision Warning, Engine,Fuel/Propulsion System,Engine,Lane assistance/ Departure, and Lighting. There could be more to include but heres the dangerous issue I encounter everyday I utilize my vehicle,that has yet to be fixed nor addressed appropriately when I articulate EXACTLY what I feel,& see occur.My safety & everyone esle has been put at risk everyday which caused my 1st accident which I predicted was potentially likely since May 1,2025. It occurs exactly the same everytime just like the 1st terrifying experience: Id be stopped at a red light,intersection waiting for green light. With foot on brake between 5 to 10 seconds later I can feel the brake disenaging with my foot fully and physically on the brake simultaneously my vehicle screens will light up indicators erractically,(ghost touch,touch screen digitizer failure), while LUNGING FORWARD 5-7 ft on it OWNS,simultaneously screen blackout,& vehicle screen system reset followed by vehicle putting itself in emergency brake.This puts everyone around at RISKS AS MY VEHICLE OPERATES ON ITS OWN, which caused an accident at a red light where my truck plowed into the vehicle in front of me.Ive waited for an independent service contractor to evalute on 4 different occasions which they failed to appear or make contact on THEIR desired scheduled dates.The dealership has failed to reproduce due to unsatisfactory failed service repair attempts, discrepancies in verbal & documention.Absolute lack of concern for my safety or interest in issue, as at least 2 comeback services were met with breach of contract by dealer.The DEALERSHIP has been the only ones servicing my vehicle & according to their top tier diagnosis components successfully checked out in contrast to my many reoccurring service request for same issue.Prior to failure no warning lamps or messages appeared.

All issues have been reported and duplicated by the dealer. 1. Upon hard acceleration, vehicle dash flashes service 4 wheel drive and all lights surrounding the shifting knob flash. In one instance, it locked into 4 wheel (high) and was difficult to steer. Cleared upon restart. 2. Backup camera went totally to blue screen, no camera. 3. Instrument panel went dark when driving, no speedometer or other information on panel. 4. Front and rear end collision warning lamp indicates off, but never manually disengaged. 5. Other warning lights on periodically for no reason. 6. Since most of these items clear upon restarting the vehicle, it's often difficult to get to the dealer for inspection. They have, however, witnessed most of these incidents and in some cases have reproduced them when leaving the vehicle with them. 7. Frequent warning light illumination unavailable, service required prompt appears

My 2022 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: Forward Collision warning randomly stops working until a restart. My TRX has multiple suspension modes, since the update I am stuck in Off Road mode, which means my suspension is very loose and not really meant for on road driving. 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 the federal safety agency open a defect investigation and require Ram to correct these failures.

I do not believe my truck's forward collision warning and emergency braking work. I have had a few very close calls with rearending a vehicle in front of me and the truck did not brake automatically or give any collision warning. Also, the adaptive cruise control is set on the furthest distance, but it follows very closely to the vehicle in front of me. Like a 1.5 second length at the most. When I change the setting to follow closer, it will follow a vehicle within inches. I believe this causes a safety issue with a potential crash.

All major braking and safety systems have failed, including the parking brake, 4-wheel drive, cruise and adaptive cruise control, lane departure warnings, blind spot monitoring, and parking collision alerts. These failures occurred at the same time, and we believe there may be additional issues not yet identified. Our local dealership (Barry Sanders Supercenter, Stillwater, OK) attempted multiple repairs before opening a service ticket with RAM/Stellantis. We were informed the part needed to fix the problem is backordered for approximately one year. This extended delay means we must continue driving a vehicle without critical safety systems or park it indefinitely, creating both a financial and safety burden. The loss of these features greatly increases the risk of collisions, especially in bad weather or on highways where adaptive cruise, lane departure warnings, and blind spot detection are essential. Online searches show this is not an isolated issue but a recurring problem in 2025 RAM 1500 models, suggesting a broader manufacturing or design defect.

Adaptive cruise control does not work, Forward collision warning does not work, pedestrian emergency braking does not work, auto emergency braking does not work among other non safety issues. Dealer is aware and has ordered a new infotainment system which controls all these safety features but is unable to get it from the manufacturer for the last 6 months. This system did not work from the day I picked up the vehicle

What component or system failed or malfunctioned, and is it available for inspection upon request? -The issue involved the truck’s parking and collision avoidance systems, which suddenly shut off. A warning message appeared on the dashboard stating "Service Shifter." This issue may be related to the electronic shifter module or associated control systems. The vehicle is currently available for inspection upon request. How was your safety or the safety of others put at risk? -The sudden deactivation of both the parking and collision systems while the vehicle was in motion created a serious safety hazard. Without collision avoidance functionality and the ability to securely park the vehicle, there was increased risk of unintentional vehicle movement or inability to avoid obstacles, which could have led to a crash or injury. Has the problem been reproduced or confirmed by a dealer or independent service center? -Yes, the truck was taken to an authorized dealer for assessment, and the issue was confirmed. Diagnostic tests found trouble codes starting with "U", which typically indicate a communication or control module fault within the vehicle’s network. The codes provided from the dealer are U0159, U0140, U0100, U0137, U0102, U10121, and U0101. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -The issue has been inspected and documented by the dealership. There is no indication that police or insurance representatives have inspected it at this time, but the incident and diagnostics are recorded in the dealer’s service records. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -Yes, a warning message "Service Shifter" appeared on the dashboard. This message coincided with the shutdown of the parking and collision systems. These symptoms appeared suddenly and without prior warning during regular vehicle operation.
