Sometimes while driving I experienced my powered steering cut out while taking a ramp on/off of the highway, and sometimes when i was trying to park and back up into a parking space while steering at the same time. When the power steering cut out I got lights for "Service Power Steering", "Service ESC", and "Service Hill Assist" all at the same time, and once i got a power steering light. I looked up the issue and found that there is an active preliminary investigation going on for the same issue on the same vehicle, the investigation coded PE26002. Once I handed the vehicle over to the dealer, they found that the power steering had an open circuit on the steering gear. Once they took the connector off they found that the connector was corroded and the wires were burned on the steering gear and main harness side. I had to have them replace both the steering rack, and the main harness.

Without any warning my steering wheel locked up and started jerking resulting in lack of steering and drivability. I was backing out of my driveway and started to turn onto the street when this happened. This could have been very dangerous if I had been driving on regular roads. The van is currently parked on the street and available for inspection as I was able to gently maneuver it to a safe spot. This has been looked at by a mobile mechanic who put an OBD2 scanner on it and couldn't bring up any codes. It has not been taken to a shop at this point. The dealer said over the phone that this is not a powertrain warranty because it is not engine or transmission. It has not been inspected by the manufacturer, police, insurance. There were warning lights on the panel when this happened but they didn't stay on. Checking the internet for answers I discovered that a power connection to the rack for power steering was getting corroded from not being sealed properly and water was entering the connection. Today I removed the black battery cable and checked on the connector to the rack myself and discovered the same issue many people are having. below is a photo from today January 9, 2026. The connector looks corroded and burnt. Why is this not a recall? This is not safe.

while turning a corner the power steering module shorted out the power steering rack gear assembly causing the vehicle to have control of the steering and unable to turn the wheel almost colliding with other vehicles. the power steering module light comes on along with the hill start assist, the forward collision warning, the ESM lights all come on. The steering wheel does not turn and had to tow to the dealership , the dealership informs me that there are two others in the shop for the exact same issue. The power steering module wiring harness gets moisture on the connections and causes the power steering rack gear to short out . this could lead to horrible accidents if the driver of the vehicle can not turn and control the vehicle

The FCW function does not engage if you put the vehicle in gear to soon. You must wait at least 5 seconds after starting the engine before shifting into gear or else the FCW will not turn on. The dealer said there is no fix. I believe this is a software issue. This has been functioning this way since the vehicle was new.

From purchase the UConnect system has faulted out and have effected items like Navigation, etc but wasn't a real problem. On 7/18 I had my dealer perform recall # 66B/the federal safety agency 24V‑436 On 7/20 the UConnect system began faulting out but this time it started Disabling the Automatic Emergency Braking while driving, Disabled the parking brake when it was set, Indicated that various lights were not working when they were. The dealership worked on it extensively with the Corp service system reflashing the system, etc and it worked Ok for about 100 miles when the above problems have all started again. I have reviewed several social media sites and notice the UConeect system is very problematic. I am concerned most about the UConnect system turning off what I consider very important safety functions and while this seems to be a long ongoing problem RAM CORP SERVICE doesn't seem to be able to correct it The local Dealership has been great to work with but can only do what CORP tells them to do
