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.

Manufacturer has not timely completed the following recall in a manner that promotes safety or the urgency to protect lives. My particular vehicle is a class B recreational vehicle that cannot be used since this recall. I request NHTSA exert its authority to compel the manufacturer to expedite immediate recall safety repairs.
The vehicle experienced a thermal event that was caused by a defective fan motor. The vehicle has been inspected by stellantis and a third party investigator. Report attached
The vehicle's power steering does not work properly, especially at slow speeds and when attempting to back up. However, it has also failed while traveling on the interstate highway at high speeds. When you attempt to make a turn, the power steering feels like it is fighting you and wants to pull the vehicle back in the opposite direction. I took the vehicle in to be serviced, and they replaced the battery which removed previous warning messages. On two occasions, while traveling at slow speeds and making a turn into a shopping center parking lot, the vehicle resisted my attempt to make the turn such that had a car been coming out of the parking lot, rather than complete the turn, I would have run directly into the side of the other vehicle. While travelling on the interstate at 70 mph, I momentarily lost steering and had there been vehicles behind or beside me at the time, I believe it would have resulted in an accident. Fortunately, the cruise control simultaneously shut off.
The vehicle experienced a loss or severe reduction of power steering assist. The steering became very difficult to turn, creating a safety concern while operating or maneuvering the vehicle. The issue appears to involve the electric power steering system, steering rack/rack-and-pinion, and/or related electrical harness or connector. The problem occurred on or about 05/21/2026 at approximately 49000 miles.While driving. The vehicle was inspected by dealer, The diagnosis was harness/connector issue, corrosion/water intrusion, power steering module connector issue. The repair estimate/repair involved $4800. I am concerned this may be related to NHTSA investigation PE26002 involving 2022–2023 Ram ProMaster power steering assist failure and possible water intrusion into the power steering module connector.

On December 23, 2025, a 2023 RAM ProMaster 2500 Van used as a commercial fleet delivery vehicle in [XXX] suffered an engine compartment fire. The vehicle was declared a total loss by the insurance carrier. At the time of the fire, the vehicle was subject to open Safety Recall 25V-720 / Manufacturer Recall 67C, issued by FCA US LLC for a defective cooling fan module with premature bearing wear and inadequate fuse protection on the 400W fan circuit — the exact defect identified as a known fire risk. No remedy was available at the time of the incident. The interim recall notification letter had been received but the vehicle could not be repaired as FCA had not yet developed or made available a fix. The vehicle was inspected by insurance representatives and declared a total loss. No warning lamps or prior symptoms were observed before the fire occurred, consistent with NHTSA's own warning that affected vehicles may fail suddenly with no prior dashboard alert. The component believed to have failed is the cooling fan module. It is unknown whether the component remains available for inspection as the vehicle has been transferred to the insurance carrier as part of the total loss settlement.

EcoFlow unit wires crimped, may be inadequate on size of wire from alternator to EcoFlow unit . Leading to overheating and potential fire danger .
Emergency call system has never worked. Dealership and Chrysler have done nothing to resolve the issue
12v DC outlet caught fire
Moisture in the air has corroded the wiring harness and connections to the Rack and Pinion causing the power steering to freak out and jerk the sheen all over the place and then cut out while driving.
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.

R/F signal light not working properly upon delivery. Fast flashing on instrument panel. Same issues of recall on the 2021/22 Promaster. Vech/camper is at Lakeland Dodge, FL. Harness replaced still with problem. Now they are ordering a mirror part hoping this resolves. Vech purchased from RV General, Dover FL
Camping World, Freedom Roads LLC did not complete NHTSA Manufacturer Recall Number 66B NHTSA Recall Number 24V-436 prior to delivery on or about August 8th, 2024 and did not inform me of this recall. Unacceptable! I am scheduled to complete recall at a Ram dealership on 12/10/2024.
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/NHTSA 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
1:MPH randomly changes to KM/h on the instrument panel and Uconnect radio settings. 2: Automatic Parking brake keeps re-enabling on the Ucconect radio settings when it has been set to disabled. 3.SiriusXM radio starts back at station 1 XM Preview when van is started up. 4. Van will sometimes lock automatically by itself without permission with the vehicle off. 5. Other: No matter what settings I set the vehicle at overtime they keep reverting back to whatever they were originally at. 6. Soft reset and Hard reset were performed with no prevail and issues are still present. No software updates are available as well.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
