2021 Ram 1500: screen or infotainment failure

Filed Nov 6, 2026 · Electrical, Lights · MN

There are issues where the dash display goes blank and the headlights do not operate properly. The headlights will not switch from dim to bright automatically or manually. At times one or more lights will not even illuminate. It is not a constant problem but intermittent instead. We are not comfortable driving the vehicle after dark because it may happen at any time.

Electrical system shutdown including loss of all safety features (blind spot, emergency braking, abs, traction control, towing), climate control options (AC, Heat, window operations) and user interfaces (U-Connect screen, center gauge cluster). Initial warnings (2) on center cluster on listed- 1. Blind Spot Detection Disabled 2. 115 Volt Cargo Power Outlet On All electronics, controls were then disabled- black screens, inoperable controls. Passenger rear windows, sliding back glass, panoramic sunroof and drivers side mirror are the only working electronics other than speedometer. Upon inspection of all fuses, relays, battery, alternator, and checking all accessible wiring related to blind spot and auxiliary power and finding no defective issues, web searches were performed. Based on numerous other RAM owners on multiple forums on RAM trucks 2020 and newer with blind spot avoidance, we found a likely culprit in the driver's side brake light. Upon inspection of the left rear brake light assembly, a small hairline crack was located with signs of internal moisture/ condensation. After observing the internal moisture the drivers side rear brake housing was removed and disconnected for closer inspection and potential repair. While the driver side brake light assembly was removed, an instance occurred when my wife needed the vehicle. Upon and during the entirety of operation over the next 1.5 hrs driving approximately 63 miles, all electrical options worked as intended minus the blind spot avoidance and a new warning on brake lamps (obvious as tail light had been removed). During this time, the proximity sensor housing was removed from the assembly, water accumulation dried, and allowed to remain open next to a dehumidifier for 4 hours. Epoxy was applied over the hairline Crack, and any area that looked as if could be affected. Unit was reinstalled, however all electronic failure returned. Unit removed again to attempt humidity removal- all electronics res

The uconnect radio system freezes. It will do this and then reset. Sometimes it resets multiple times before working. It will freeze when using the backup camera. The entire screen will be frozen until it resets itself it takes approximately 60 seconds for it to reset.

After idling for 30-45 minutes in a parking lot my radio suddenly turned off (black screen), the dash indicated that my 115V Outlet showed that it was on as the indication flickered continuously. A/C will not function, only hot air blows progressively worse while driving. Windows will not roll up or down anymore, clock on the dash no longer shows up, side mirrors will not close with the button, power steps will not deploy. The vehicle also states that the blind spot indicator is off. Doors will not lock either. I disconnected the battery for 15 minutes and made sure EVERY FUSE WAS SEATED PROPERLY (interior and engine bay) as they were almost ALL loose. Now I am attempting to let the truck sit disconnected for up to two hours with the doors open and will factory reset the radio after to get the 12” screen functioning if possible.

The rear camera occasionally shows a black screen. If I turn off/on the truck its still the same. If it stays off for more than an hour and then turned back on then sometimes the camera works but some times it still doesn't work. It's very scary backing up a truck without a camera. I feel very unsafe doing so. There is an active recall for this exact issue but my truck is not affected by this recall: the federal safety agency campaign number: 23V059. Ram’s own number for this recall is 14A. How can i get this safety problem fixed if my truck ks not affected by the recall. Thanks.

Driving through town on my way home from work, the instrument cluster display went black and gauges died. I have no access to fuel level, engine temps, speedometer, rpm's, warning indicators, etc. Have to take it in to dealer for a multi-day diagnosis and hopefully free repair. 2two year old vehicle with only 25k miles.

Cause of the incident is UNKNOWN at this time. The vehicle is currently with a Ram dealership for identification of the issue and repair. The incident occurred shortly after I exited an interstate with traveling speed at 70 mph or faster. If this issue had occurred on the interstate the potential for a serious accident would be extremely high. Incident: On March 16, 2022 while driving into work the vehicle seized and would not move. This occurred as I was pulling into the company parking lot at a speed of approximately 5 mph. The vehicle had just come off an interstate and had been traveling approximately 75 mph in congested traffic. Attempts to put the vehicle into Drive, Neutral, or Reverse were unsuccessful. The shifter would automatically move back into Park. I shut the engine off and then restarted. This did not resolve the issue and the truck would not go into any gear. The START/STOP Ignition also would not go to the OFF position when I shut the engine off. It would go to the ACC position only. I noted two different messages on the display when I restarted the engine. "Service Trans Press Brake When Stopped Key Off Engine to Engage Park" and "Service Trailer Brake System". I check the Error Code with an OBD device. The error code was U0402 "Invalid Data Received From TCM". To move the vehicle I disconnected the negative battery lead for 5 minutes and then reattached. This cleared the error and I was able to put the vehicle into drive. I took the vehicle to the dealership and will not drive it until repaired. The dealership had requested I take the vehicle and continue to drive as is to see if the issue would re-occur. I refused this as it could lead to a serious accident and potential loss of life.

On several occasions since purchase of a new 2021 RAM 1500 the backup camera has failed to work when in reverse. A black screen is displayed. Repeated efforts to turn the backup camera on by putting the vehicle in reverse or selecting the backup camera from the control panel resulted in a black screen. Repeated efforts to turn the vehicle off and on several times consecutively had the same result. I also tried opening and closing the tail gate with no positive result.

Backup camera sometimes has blank screen and guide lines sometimes are not there and zoom function does not work when no guidelines. Truck has been to the dealership 5-7 times, in January they replaced the camera itself but did not fix the issue. I was to they cannot do anything at this point unless it fails at the dealer. It does not have the trailer backup camera.
