The Electronic Power Steering (and EPS Module) failed, making it incredibly hard to steer especially at low speeds. Dealer confirmed that the power steering rack has failed. All power steering features and lights came on, rendering the vehicle inoperable while driving doen the road. This is a serious safety concern.
NHTSA complaint #11757934 — an unverified report by a vehicle owner.
Vehicle wheel would suddenly jerk when driving. Video of steering wheel doing this was taken while parked. The suddenness of this created immediate dangers to the driver and any around due to the unpredictability of the steering. Vehicle was brought to a dealer/service center where they diagnosed a corroded wire harness that required the entire steering rack to be replaced. There were no warnings or dash lights on. Vehicle is still at the service center four weeks later because the wire harness is unavailable and the vehicle cannot be safely driven.

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 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.

Power steering electrical connector(s) completely corroded from moisture intrusion, while driving ps shut down and warning light flashed. Had to suddenly correct in a corner without ps, almost had an accident. It is available for inspection, as I cannot afford to fix this yet. Dealer inspected problem, ps rack and harness need replacement at a cost of appr. CAD $4000-5000. Have not contacted manufacturer yet, but will now. Vehicle warranty just expired and has only 26 k km on it.

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.

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***

NHTSA complaint #11752569 — an unverified report by a vehicle owner.
The contact owns a 2023 Ram Promaster 2500. The contact stated that while driving approximately 65 MPH, the message “Power Steering Service” was displayed with a high-pitched whining sound coming from underneath the hood and the dashboard. The vehicle was taken to the dealer, who diagnosed that the steering gear EPS module and jumper harness needed to be replaced, and the vehicle needed an alignment. The vehicle was not repaired. The contact researched online and associated the failure with NHTSA Action Number: PE26002 (Steering, Electrical System). The manufacturer was not informed of the failure. The failure mileage was approximately 40,000.

Steering Rack and Pinion failure due to corroded electrical connection plug. This occurred in april, 2025, when the van had less than 15,000 miles on it. Took the van to Blue Ridge Chrysler Dodge dealership in Abingdon Va .for Warranty repair. Plug was taken off another vehicle to put on mine aaaand dielectric grease added to hopefully keep the replacement plug from corroding too. Location of plug makes it susceptible to water infiltration, a definite design flaw that is likely to cause trouble again in the future.
NHTSA complaint #11751417 — an unverified report by a vehicle owner.
While driving, a “Service ESC” warning message appeared and the vehicle suddenly lost power steering assist, causing the steering to become extremely difficult and creating a serious safety risk while the vehicle was in motion. The vehicle was taken to a service center, where technicians found multiple loss-of-communication codes involving the electronic power steering system. Further inspection found the main electronic power steering connector full of water and corroded. The technician documented that water intrusion caused excessive damage to the electronic power steering terminals at the rack-and-pinion assembly. The water intrusion appears consistent with a failure or inadequacy of the sealing intended to protect the electronic power steering connection from moisture. Due to the extent of the corrosion and damage, the affected wiring harnesses and rack-and-pinion assembly had to be replaced, followed by a wheel alignment. This failure resulted in a sudden loss of power steering assist while the vehicle was being driven.

I am reporting a severe, intermittent loss of Electronic Power Steering (EPS) assist on a 2022 Ram ProMaster cargo van at ~21,000 miles. The defect causes sudden drops in steering assistance and erratic wheel-jerking under heavy electrical loads during rapid, low-speed turns while parking.A professional dealer teardown and inspection at Dutch Miller Ram confirmed that environmental rainwater from the windshield cowl completely breached the factory weatherproofing seals. Standing liquid was found pooling inside the bottom floor of the connector housing, causing severe copper oxidation (galvanic corrosion) and visible electrical arcing on a constantly energized 12V male pin inside the EPS gear cylinder. This high-current bottleneck drops voltage under load, causing the internal ECU to cut assist as a safety fail-safe.Critically, this design defect created an immediate, progressive cascading failure dating back to the very first month of ownership. Because this 12V power line remains constantly "hot" while parked, the pooling water established an un-metered short-circuit bridge directly to the frame ground. This forced an aggressive parasitic electrical drain that repeatedly flattened the battery after sitting for short two-week intervals throughout its lifespan, destroying the original factory battery.The dealer's safety protocol requires a complete steering rack replacement. However, because Ram recognized this vulnerability, they completely superseded the part with a redesigned assembly that forces consumers to purchase new, non-faulty tie rod assemblies just to make it compatible, inflating costs to over $6,000. This data directly supports the active NHTSA investigation into 2022-2023 ProMaster steering modules. Furthermore I imagine that since some people may continue to drive the vehicle under this particular condition of "barely being affected" until there is sudden failure on the highway or zero signs prior to catastrophic failure.

NHTSA complaint #11749895 — an unverified report by a vehicle owner.
I started having issues with the power steering. It started when I was leaving work about a month ago. Pulling out of the parking lot,it starting pulling to the left, when I was turning right. I got home and started looking for the power steering fluid tank, and couldnt find it. It was fine for a few days after that. Then I was making a right hand turn, it felt like it starting resisting the turn and tried to straighten out halfway through the turn. Another time, I was going around a left hand curve, maybe 45 mph, it fought back and pulled to the right. I have had a couple other issues, along the same lines over the last month between 5 and 45 mph. I was looking up information on the power steering, finally found it in the owners manual, that I have electric power steering.

The power steering for my 2022 Ram Promaster failed on 3/7/24. The safety issue this caused was that steering the van was nearly impossible. Fortunately, the failure occurred while I was in a parking lot. The van had to be towed to the local dealer. The defective parts were on backorder (part number 6TB16JXWAC Module-steering control) and arrived on 5/21/24. This was covered under warranty and the repair work was done by the local dealer. There weren't any warning lamps that would indicate an issue. I used the van to drive to the jobsite, worked for a few hours, and the issue occurred as I was leaving for the day.

whenever I was driving on the highway at 80MPH it felt like someone stepped on the brake pedal abruptly for a split second and the car with squiggly lines behind it appeared on the instrument panel, then disappeared. Goin this fast and having that happen is a major safety issue. After this happened the steering felt all over the place like I was floating and if I turned the wheel just a tiny bit the vehicle thought I turned it a lot and over corrected, needless to say I was all over the highway. Then the backup camera stopped working, the screen was completely black. I reset the screen and it worked for a couple seconds but then the color and picture got very distorted and then again went to a black screen.
