Related recall: NHTSA 25V720000 / Chrysler 67C - "The electrical circuit for the radiator fan may overheat." Fire/injury: No fire / no injuries; component overheated and burned/melted. Complaint narrative (paste this into the form) The radiator cooling fan on my 2020 Ram ProMaster 3500 (3.6L gasoline V6) repeatedly became stuck running / would not shut off on multiple occasions. The cooling fan electrical circuit overheated, and the fuse and fuse box (power distribution center) burned and melted, which in turn...

damaged the adjacent wiring harness. The fuse did not protect the circuit before the overheating and thermal damage occurred. This is the identical failure mode described in NHTSA recall campaign 25V720000 (Chrysler recall 67C), which states that "the electrical circuit for the radiator fan may overheat" and that "electrical circuits that overheat increase the risk of a fire," with a remedy of replacing the cooling fan module and fuse. My vehicle is a 2020 ProMaster, within the 2018-2026 model years covered by that recall. However, when I contacted Ram/Chrysler, I was told my VIN is not included in the recall population. I am filing this complaint because my vehicle experienced the exact defect the recall was issued to address - a stuck-on radiator cooling fan causing the fan electrical circuit to overheat and burn the fuse box and wiring harness, creating a fire risk. I had to pay to repair this damage. I request that NHTSA review whether the recall population should be expanded to include my VIN and other affected vehicles exhibiting this same failure. Documentation available on request: photographs of the burned/melted fuse box and damaged wiring harness, and repair invoices showing replacement of the cooling fan/fan module, fuse box, and wiring.

The rear backup camera has been intermittently failing for over one year on this 2020 RAM ProMaster 2500. The failure has now become more frequent and extended. When the fault occurs, the infotainment screen displays a permanent "Camera System Unavailable" message that blocks access to all other functions including radio, phone, and navigation. The failure occurs in all gear positions and persists after engine restart. The only temporary resolution has been extended power-off periods. The dealer confirmed this...

vehicle is covered under Manufacturer Recall 59C / NHTSA Recall 25V-552 but stated no remedy parts are available. No written service record was created for this report. No interim remedy or timeline was provided. The recall was issued August 2025 and as of May 2026 remains unresolved. This constitutes a direct safety hazard during reversing maneuvers, consistent with NHTSA's own safety risk description for this recall.

Pertaining to the open recall: Manufacturer Recall Number59C NHTSA Recall Number25V-552 We had called last year when the back camera started acting up; was told there was a pending recall to release by the end of the year (Dec 2025). Called back January 2026 to see about a fix on the recall, was notified they have the recall, but there wasn't a part for the fix yet and to call back later. Called back March 2026 because the issue seems to be getting worse and the rear camera sometimes just doesn't turn on at all;...

and was told there was still no part yet. So was going to wait another two months before calling again. But today (April 2026) one of our drivers accidently backed into a truck, luckily all of our drivers have been hyper cautious so they weren't going very fast so there were no damages to the other vehicle. Not having a fix for the rear view camera system still, has made our drivers feel uneasy when they have to take this van out. It's definitely a huge safety issue, especially since there is no visibility to look out the rear windows. A fix for this would be greatly appreciated.

This van has been at a Dodge dealership shop for the same melted fuse box issues over 6 times and caught on fire last week while driving it back from the dealership to be used.

The vehicle is subject to two active safety recalls issued by the manufacturer, including a recall related to the rear backup camera system. The manufacturer has acknowledged the safety defects, but no remedy has been released for an extended period of time. The backup camera recall affects rear visibility while reversing, which poses a safety risk to the driver, passengers, pedestrians, and nearby vehicles. The backup camera intermittently fails or does not display an image as intended. The recall has been open...

for several months, and no estimated repair timeline has been provided by the manufacturer or dealer. I have contacted the dealer/manufacturer and was informed that no remedy is currently available. This vehicle is used regularly, increasing concern about continued operation with unresolved safety defects. The vehicle remains in service with known safety defects and no corrective action offered. This report is being submitted due to the prolonged delay in providing a remedy for acknowledged safety recalls.

Image on the backup camera is flipped. I checked online forums and it seems like this is a common problem without an adequate solution to make backing safe

Electrical system

So this is an Amazon delivery vehicle. The driver stuck his head out the drivers side window to get a better view when backing up, as his head was out the window he hit the window switch and instead of the window going down, it malfunctioned and went up instead, catching his neck and his entire head was stuck. Concerned citizens even tried getting inside the van and helping but when they tried to press the window button DOWN, it would only go up. (The wrong way) this resulted in almost having to break/smash the window

Radio system, navigation, backup camera and associated telematic system failure. The radio in the RAM Promaster functions as a control center for many safety functions. It intermittently fails while driving the RAM Promaster. It has been in multiple (4) times for service. Replaced on 6/24/2021. Problem reoccurred on 8/12/2021. No solution at this time from Fiat - Chrysler (FCA). This is a problem that may be internal and does not report buss data. Safety put at risk with no camera functions or communications.
