I have taken my vehicle to Ram dealer letting them know the Forward Collison Warning (i.e. 'BRAKE' to show in display and brake if I don't) is not working. Both time they said it was working and basically showed me the front sensors setting. I have tried to test this on the road and almost rear ended three cars: 1) speeding up when car in front is at a traffic light, 2) accelerating to 65 mph coming up on a slower car, 3) coming around a curve on a two lane highway with car coming in opposite direction. No warnings at all. My Honda Pilot shows the warnings in each of these cases. So I went back to the dearler and explained that on the Ram forum, https://www.ramforum.com/threads/anyone-else-with-a-fcw-forward-collision-warning-problem.142051/page-3#post-2623613, other drivers have noticed same thing. My RAM is a 2020. I saw where someone with a 2019 has same problem. …
Vehicle experiences intermittent but repeatable safety-related electrical failures affecting turn signals and blind spot monitoring. The left turn signal remains engaged after canceling and does not shut off unless the opposite turn signal is activated, causing incorrect signaling to other drivers. This occurs without driver input. At the same time, the Blind Spot Monitoring system intermittently displays a "Blind Spot System Unavailable" warning and disables the safety feature while driving, increasing the risk of unsafe lane changes. Vehicle was inspected and diagnosed by an authorized Ram/Stellantis dealer. Dealer verified the concern and documented fault code B2225-00 - Steering Column Module Internal Failure, confirming the steering column control module is malfunctioning internally and not posting correct left/right turn signal inputs. …
While I was driving my vehicle, the power steering warning came on and moments later the steering wheel locked - I could not steer my vehicle. I stopped the vehicle and it started firing all sorts of warnings. It was like all systems went haywire. Service shifter, service power steering, service electronic stability control, acc/fcw unavailable, service required, service airbag system, collision control, check engine, anti-lock breaks. The windshield wipers started without being tuned on, the engine revved up an got very loud like an airplane engine. I turned off the vehicle. When the tow truck arrived, the truck would not start so he walked away to grab the pulley and the truck started on it's own. My biggest concern is that I lost the ability to steer while I was in motion. I was informed of a VB8 recall for power steering but told my vehicle didn't qualify. This is a serious concern! …
The BSM service notice triggered a shut down of all controls associated with front windows and climate control. The UConnect system shuts down completely and the climate system defaults to defrost with fans going to max and the heat turned up to Maximum temp. With front windows control disabled you are unable to lower or raise windows and with Uconnect shut off there is no way to turn off the heat. This takes place while driving. You are literally cooking inside the vehicle The BSM service light came on to indicate service needed on a sensor located in the tail light assembly. That notification triggered the electrical malfunctions of the other systems. After sitting for 12 hours the truck systems would reset. As soon as I started driving the same sequence of events would take place again. …
ABS module/hcu failure Jan 13, 2025. No indication of problem prior to failure. When failure occurred, vehicle was traveling around curve in road at 50 mph when all warning lights on dash lit, loss of power steering, engine shutdown, loss of power brakes. Vehicle had to be towed home then to dealer (Davis Moore Ram Wichita Ks). Dealer diagnosed as ABS module with possible HCU failure. Told by dealer no parts available for repair, I confirmed with on-line search with other dealers. ABS Module Part # 68728132AA is not being made available to any dealers (backordered) for the repair.
