2019 RAM 1500 driver assist problems

LANE DEPARTURE: BLIND SPOT DETECTION

My 2019 Ram 1500 Rebel has recurring electrical/communication failures that occur every day. The truck repeatedly displays “ParkSense Temporarily Unavailable,” “Service Shifter,” “Service Tire Pressure System,” and “Tire Pressure Unavailable.” The ParkSense sensors often do not activate at all, leaving me without parking assistance while backing up. The system also repeatedly pings with warnings throughout the day. When “Service Shifter” appears, the truck shifts roughly and the transmission does not feel like it is shifting correctly. I am concerned this could indicate an electrical or communication problem affecting the electronic shifter, transmission operation, gear selection, or vehicle control. The truck also has an ongoing water leak around the rear window, including the upper portion and near the sliding window. The electrical problems appear worse during high humidity, although they have also occurred during winter. I am concerned that water intrusion could cause corrosion, electrical shorts, module damage, or other safety hazards. A reputable independent repair shop inspected the vehicle and identified a U-code communication fault. The problems continue to occur daily. I am concerned about the risk of a collision from losing ParkSense, potential transmission/gear-selection problems, and water-related electrical damage. I am requesting that NHTSA investigate whether these recurring failures represent a safety defect affecting 2019 Ram 1500 vehicles. The vehicle is available for inspection.

LANE DEPARTURE: ASSIST

When driving the truck the power steering would go out and make the truck almost impossible to turn. This is dangerous when driving as you cannot turn, avoid a collision, etc. I've had vehicles without power steering, and this was like the truck is actively pulling against you when trying to turn. The dealership did a diagnostic and said the power steering rack (electronic) needs to be replaced completely as it's going out. I'm not sure if it's related, but I've had other issues before this where my lane assist and cruise control would flash while in use and all turn off while driving down the road as well. There was no obvious check engine light or codes for this, just the occasional shutting off of my systems and power steering while operating the vehicle.

BACK OVER PREVENTION: WARNINGS

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.

The star connector on the CAN C BUS will start to have communication problems with the all the systems on that star connector approximately after about 15 to 20 min after driving. Systems that were constantly going in and out were the front and rear parking sense, ABS and traction would go out. Service shifter message, caused the transmission to up shift while driving at a constant speed. After getting a check engine light, I hooked up my code reader and had a code for the park sense control module. I proceeded to replace that module and was unable to get the code to go away. Upon further investigation, I found a history code for the CAN C BUS PERFORMANCE code and researched on this topic in the forums with other owners of the same truck and looked for any maintenance for this topic as well. These owners would have the same problem that my truck was having and the dealerships were unable to pin point the malfunction of all these systems. I did find video of an owner that had the same problem as my truck and he was able to pin point the problem down to the star connectors. The star connector would slowly over time while the vehicle was on would slowly take on more power then it was supposed to and overload the star connector. Upon learning about the star connectors, I learned how to replace them and after I replaced the star connectors for the exterior and interior components of the vehicle, everything went back to normal. I do still have the star connectors that were taken out incase I wanted to get them tested for the same issue the other guy found out

The issues started with the sunroof not closing. And the uconnect touch screen inoperable ( it went black and no options available ) It seemed to be a fluke and resolved itself. But within a few weeks the icons for the driver and passenger seat heaters were no longer on the screen. Now that the season has changed and temps have dropped, the drivers side heater will automatically come on when the truck is started and it’s below a certain degree outside. It gets crazy hot and will only shut off when the truck is turned off. This was followed by the icons for the radio options resorting themselves and the one for USB disappearing as well. The usb connection still works, but it has to automatically switch over when plugged in, it cannot be manually selected. Lastly the ParkAssist seems to have a mind of its own. Sometimes it will function as intended. Other times when I start the truck it flashes a warning that the park assist is unavailable and the lights on the switches are on showing it’s been disengaged. When pushed they will flash and then turn solid again. Other times it will happen while I’m driving. There will be a ding and the unavailable warning will flash on the screen. When the icons first disappeared I called mopar/uconnect customer service. They tried to walk me through some diagnostics but none of it worked. They suggested maybe getting a software update. But couldn’t tell me if that would fix it or not. When I asked if it didn’t they just said I’d have to replace the whole uconnect system.

BACK OVER PREVENTION: WARNINGS

To whom it may concern, I am making a safety complaint on a component that failed while operating the vehicle. My vehicle is a 2019 Ram 1500 Bighorn DT. The component that failed and almost cost me to crash my truck while in reverse and parking is called The Park Sense and The Rear Parking Assist . I started to have this problem back in the Summer around August 2024. I have brought the vehicle in to my dealer ( CHRYSLER, JEEP, DODGE OF PARAMUS N. J.) several times already, the first time they replaced the Park Sense Sensor Module and reset the computer. No sooner then I got home from the dealership and was reversing in my driveway the error messages came on and the truck did not sense the garage door and continued to back up thankfully I was able to brake hard and stop 6 inches from the door. Not only did the Park Sense warning come on but also The Rear Brake Assist did not stop the vehicle like it has in the past. I brought the vehicle back to the same dealership and they worked on it for about 6 hours gave it back to me and said they rerouted the wiring harness for the park sense module and it was working fine. As I get into my truck to leave the error messages came on the dashboard so I walked inside and showed the service manager and the tech that just finished working on my truck. They said to bring it back, they had no regards for my safety or the safety of others letting me leave the dealership with the truck acting up cause from time to time the brakes would suddenly come on causing the vehicle to stop abruptly. Nevertheless I strongly believe that there is a safety issue with the truck's Park sense sensor and Rear Brake Assist too. I do not know what to do can someone please help me? Thank you.
