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 NHTSA 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.

2022 Ram PromasterSteeringDriver assistance

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 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: [[redacted]] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
