2022 Ram Promaster driver assistance problems

Filed Aug 17, 2026 · Driver assistance, Steering · CO

Intermittent 'Service Power Steering' and LaneSense warnings first appeared in May 2026. Repair shop found Diagnostic trouble code C1593-49 - Steering torque sensor circuit/internal electronic failure. The repair shop found water intrusion and corrosion at steering electrical connector(s). Cleaning did not resolve the fault. Diagnosis: Internal steering torque sensor failure. Sensor is integral to the electric steering rack; complete rack replacement required. Photos are available for inspection. Safety of the driver and all others on the road was at risk, as the 2022 Promaster 3500 is a heavy vehicle that could become unmanageable without power steering. Problem was confirmed by EAS Tire and Auto in Lafayette, Colorado. The component was returned to Mopar when the new component was ordered. This issue is an additional example/complaint to the federal safety agency Investigation PE26-002 for intermittent or complete loss of electric power steering, including reports involving water intrusion and corrosion affecting the power steering system. My vehicle exhibits substantially similar symptoms and diagnostic findings. I have a finalized repair invoice, diagnostic report showing DTC C1593-49, and photographs of corrosion/connectors.

The forward collision light has been on but has not been affecting driving. Since I saw that here I figured it was worth mentioning. I have mentioned this to the dealership that is handling the current recalls as well. The more pressing issue is the steering. It happened once before where I was backing up and the steering wheel became difficult to rotate and violently jerking back against the direction of rotation. After shutting down the van and restarting it the issue had seemingly gone away. I emailed RAM about this initial occurrence but have yet to hear back. Last night, July 26, 2026, the issue occurred again as I was attempting to back out of my driveway. As I tried to turn the steering wheel it seemed to "fight" me, becoming difficult to rotate and violently jerking the other way against the direction I was attempting to rotate it. I switched from reverse to drive and was able to re-park the van where it was parked prior. My safety was not compromised in any considerable manner as this occurred at low, "driveway" speed. It was just me in the vehicle with no one else around. The problem has not been reproduced by a dealer yet nor has it been inspected by a dealer or service center. The warning lamps for the ESC and EPS came on once the problem began occurring but seemed to turn off after restarting. The problem appears to be currently intermittent in nature but, based on other accounts, the fact that this is occurring is seemingly indicative of a more serious issue in how this vehicle was manufactured. My concern is this happening at highway speeds where my safety and the safety of others will be jeopardized. ***I have a video I can send you but the link below does not allow mp4 files***

Promaster 3500 Forward Collision Warning turning itself off in Uconnect. Uconnect is where you can turn off FCW or set it to warning only, or warning and braking. I want it ON all the time but it keeps setting itself OFF. I turn on the vehicle and I see the warning light indicating it is turned OFF. I have to go into setting and set it manually. I will travel to get gas and when I re start the vehicle it is set OFF again. If I don't happen to notice it, I'm traveling down the road without this safety feature, which to me is dangerous and just not right. My Promaster is a Roadtrek van and the service manager at the dealer where I purchased the van says he sees this light on all the time on other Promaster vehicles and just ignores it. I see many posts on Roadtrek and Promaster forums that reference people having the same issue. Ram dealer finally acknowledged the issue but is unable to get any acknowledgement from the manufacturer that they are working on a fix. I've had this issue from day one and have taken it to the dealer several times with no resolution. This is one thread that documents what I have experienced as well: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The fcw/acc started as intermittent but now doesn't function at all seems to be common issue from research. There were warning lights indicating an issue. Van was at a dodge dealer for fuel and other electrical issues

While cruising at highway speed with adaptive cruise control enabled, the vehicle will incorrectly detect traffic/speed signs and will rapidly decelerate on a highway in traffic. I believe that the message that displays after detecting the new speed limit (improperly based on a sign other than a highway speed limit sign) without giving the option to reject using the "resume" button before. There is an option to disable traffic/speed sign detection, but that must be manually disabled in software every time the vehicle is re-started. Adjustment of the speed during adaptive cruise control based on traffic/speed signs should be disabled for safety. It's fine to have the speed limit displayed on the dash, but dangerous to have the vehicle adjust speed on its own without sufficient warning, or at all. I would like to request that RAM be directed to disable the software connection between traffic/speed sign detection and the adaptive cruise control so that, just like regular cruise control, the operator chooses the vehicle's speed. Note that this issue has happened many times since I've owned the vehicle, which was purchased as new, but I am now complaining to the federal safety agency because I experienced multiple incidents on my most recent trip that might have risked a rear-end collision from a vehicle following me when deceleration occurred.

Van brakes unexpectedly causing loss of control of vehicle for up to 5 seconds. Cannot accelerate when this occurs. While entering a major highway and accelerating, the van braked on its own and would not accelerate causing a semi to almost run into the back end of the van. The braking happens frequently and without warning. There is no rhyme or reason as to when it will occur as in road conditions, speed, curves, weather, etc. Took to Lithia dealership in Billings, MT four times and the problem still has not been resolved. 10 Aug 2022: Lithia could not verify the forward collision error. 1 May 2023: Lithia pulled code C14A5 sensor blinded and ordered new camera. 7 July 2023: Lithia pulled code B1006-49 internal electronic failure, removed and replaced the FFCM and calibrated the camera. 25 Sep 2023: Lithia pulled code C14A5-92 sensor blinded and the FFCM was recalibrated Turned Forward Collision off but the unexpected braking still occurs. This issue has been ongoing ever since I purchased the van in July 2022. This is an extreme safety issue as I have absolutely NO CONTROL over the van when the forward collision takes over.

When driving on a freeway or highway, without cruise control on, & the pavement surface changes color &/or texture (eg: going onto a bridge/overpass) the vehicle will decelerate quickly & without us pressing the brakes. All the systems were checked by Dodge Ram & were showing no errors with software etc, as we thought this was traction control not working properly due to a software problem etc.

Forward Collision Warning ("FCW") shuts down during vehicle operation, FCW Off dash warning light comes on, dash message system indicates FCW system restarting a couple of times, and then messages FCW unable to start, take unit to the dealer for servicing. This happens about every other time vehicle is started. Vehicle taken into local dealer twice, the last being on May 22, 2023, where dealer confirmed it was able to reproduce problem. From repair invoice: " 2960 NEEDS FORWARD FACING CAMERA FOR HALF CAMERA FAULT Cl4A5-92. SENSOR BLINDED BUT CANNOT REPLACE DUE TO CHRYSLER CALIBRATION PROCEDURE CURRENTLY UNAVAILABLE AT THIS TIME." I purchased unit brand new, 59 miles on odometer. FCW turning off has happened intermittently since I purchased (February 2023). I reached out to the manufacturer, FCA LLC, last month via e-mail and they could not provide and expected date replacement/repair parts will be available. My assigned service advisor at the local dealer no longer returns my calls or e-mails on when part will be available. Please note other 2022-23 Promaster owners have the same forward collision warning problem too.
