NHTSA ODI 11691377

Initial Diagnosis: We had the vehicle towed to a dealership for repair after losing steering while driving. The dealer's service department informed us that the issue was caused by water and corrosion in the electric power steering rack. They also indicated that this is a known issue, suggesting that the wiring harness seals are failing and allowing water to damage the system. Video the dealership sent us of the issue can be seen at [XXX] Repair Timeline: On July 30, 2025 I was informed that the replacement part for the steering rack was on backorder for approximately 45 days. After waiting 56 days, I contacted the dealer again on September 25. They informed me that they were unable to get the part. The dealer stated they could not locate the part even after contacting other dealerships, suggesting a widespread shortage. The reason given was a high volume of similar repairs. Requested Action: I am reporting this to the NHTSA because the sudden loss of steering is a severe safety defect. The widespread parts shortage suggests this is a common failure. The manufacturer needs to address this issue and provide a remedy to prevent accidents. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My company issued 2023 Ram Promaster has an issue with the cab filling up with raw gas fumes during hot weather. They are very over bearing, make breathing difficult and of course they are flammable. I've taken it to the dealership 4 times now over the past year. The first 3 times they've said they can't replicate it and they don't smell anything. One dealership did try replacing the evap canister and fuel tank pressure sensor but this did not fix the issue. Eventually I determined the source of the fumes myself. They are back flowing from the leak detection pump filter and I even have this on video. The 4th time I took the van back, showed them the video and raised a fuss so they gave me a brand new 2025 to borrow while they try to fix my work van. Well sure enough I have caught the 2025 loaner doing the same thing and I also have it on video and have a witness. This leads to me to believe this is a factory design flaw with the Ram Promaster vans. They are supposedly submitting this to their engineering department but I do not want this getting swept under the rug. If you look up emissions recall UB4 it appears they have had this issue for years but never truly fixed it. The manufacturer is getting away with putting dangerous vehicles on the road and not properly resolving the issue.

The oil pan for the van was damaged due to debris picked up on the road resulting in a hole, which in turn drained the engine oil and jammed the engine preventing from operation. The lack of protection to the oil pan which is exposed, caused the debris to damage the oil pan. Ford Transit vans have a protection under the oil pan which prevents such incidents to occur. The vehicle was repaired for $10,172 by budget as this was a rental van. Attached are the documents pertaining to this repair. Installing some sort of protection beneath the oil pan would have saved several thousands of dollars. This is the third occurance in our fleet and other two VINs have been reported already to NHTSA.

Followup of Case # 11612576 filed 10/04/24. The issue of our UConnect system faulting out has never been resolved after much troubleshooting by the dealership. The system continues to fault out which disables the Automatic Emergency Braking system and the Emergency SOS systems also. This system faults out continually while driving. The safety features are disabled more than enabled according to the indicator lights on the display. My concern is that it disables the safety feature but question if it can also activate the braking when it shouldn't which could cause very erratic and unsafe event.

The vehicle was rented for delivery services and the oil panel underneath was damaged on the road and as a result a big hole where the metal was broken off. This has caused all the oil to drain and in turn the engine was jammed. There was no indication to the driver until the engine lights came on after the engine stoped and couldn't be driven. The oil pan material has been so fragile nor there were any protection below the pan to prevent any debris picked on the road. The vehichle was inspected by Budget and a Repair Shop and have determined the cause of engine failure is due to the Oil Panel.

while turning a corner the power steering module shorted out the power steering rack gear assembly causing the vehicle to have control of the steering and unable to turn the wheel almost colliding with other vehicles. the power steering module light comes on along with the hill start assist, the forward collision warning, the ESM lights all come on. The steering wheel does not turn and had to tow to the dealership , the dealership informs me that there are two others in the shop for the exact same issue. The power steering module wiring harness gets moisture on the connections and causes the power steering rack gear to short out . this could lead to horrible accidents if the driver of the vehicle can not turn and control the vehicle

The FCW function does not engage if you put the vehicle in gear to soon. You must wait at least 5 seconds after starting the engine before shifting into gear or else the FCW will not turn on. The dealer said there is no fix. I believe this is a software issue. This has been functioning this way since the vehicle was new.

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

I finally found a place to report issues with my 2023 Ram ProMaster 3500. I have experienced different issues with this vehicle. The turn indicator failure first started around 8000 miles. The door ajar light for the sliding door started around 35000 miles. What I believe is the traction control, has been an ongoing issue unsure of when it started, but is the most common issue. 1) Multiple times, the left turn signal randomly fails, the bulb indicator light turns on. The front left and mirror signal don't work. While the rear one does. Then out of nowhere, it starts to work again. Has happened multiple times. 2) multiple times right side sliding door sensor fails. Can be up to 2 hours after driving, the door ajar symbol comes on. Making the user interface unusable. Stop the van, open and close the door, it clears it. Then shortly later, the door ajar indicator comes on. And with the door ajar light illuminated, it does not allow the doors to be locked. 3) the traction control (i believe), on one side or the other, will grab, making a grinding noise, slow the vehicle down slightly and pull it slightly in that direction. It happens on any surface type, dry, wet, or icy. And happens at highway speeds, 50-80 mph. I've notice it happen a quite a few times when passing another vehicle. Which ever side the vehicle is on that you are passing, that side will grind (activate)
