What the reports in each category say, in the owners' own words
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
The contact owns a 2020 Ram Promaster 3500. The contact received notifications of NHTSA Campaign Numbers: 25V552000 (Back Over Prevention) and 25V720000 (Engine and Engine Cooling); however, the parts to do the recall repairs were unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repairs. The contact stated that while in reverse(R), the back over prevention camera failed to properly operate and failed to display an image of the rear of the vehicle. The failure was intermittent. The coolant level failed to remain at the proper levels and coolant needed to be added frequently. The contact stated that the battery suddenly lost power and need to be recharged more frequently. The dealer was contacted several times; however, the part to do the recall repair was not yet available. The dealer was recently contacted, and the contact was informed that an inspection was needed before ordering the parts. The dealer stated that it might take a day or two to complete the inspection and order the parts but could not provide a time for when the parts would be received or when the repair would be completed. The manufacturer was not made aware of the issue. The failure mileage was approximately 36,000.
The rear backup camera is intermediate and does NOT provide a visible image 90% of the time. When the vehicle is in reverse the display reports a message, "Camera System Unavailable". The van doesn't have rear or side windows and makes it nearly impossible to safely backup the vehicle.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
The contact owns a 2020 Ram Promaster 1500. The contact stated that while his wife was driving at an undisclosed speed, the vehicle jerked, and the transmission downshifted unexpectedly. The check engine warning light illuminated. In addition, while shifted in reverse(R), the vehicle failed to function as intended. The vehicle was taken to the dealer, where it was diagnosed with transmission failure. The contact was informed that parts were not available to repair the vehicle. The vehicle remained at the dealer for over a year and a half. The vehicle was repaired. The contact stated that on the day the contact was supposed to pick up the vehicle, the contact noticed oil stains on the ground. The contact stated that an abnormal sound was coming from the steering wheel when the gear lever was in reverse(R). The steering wheel failed to function as intended; when the steering wheel was moved, the steering wheel remained frozen in position, and force was used to turn the steering wheel. The maintenance record showed that service was performed. However, when the contact checked the oil, the oil was black, and there was a rotten odor coming from the oil and the vehicle remained at the dealer. The contact later received notifications of NHTSA Campaign Numbers: 25V552000 (BACK OVER PREVENTION) and 25V720000 (ENGINE AND ENGINE COOLING). The contact stated that when the heater was activated, heat was coming from the vents on the passenger side, and heat failed to come from the driver’s side. The contact was informed that the vehicle was repaired. The vehicle was retrieved, and days later the transmission failed to function as needed. The dealer was contacted; however, the contact was informed that the transmission had been repaired and no more repairs were needed. The manufacturer was made aware of the failure and the contact was informed that a field inspector would be sent to inspect the vehicle at the residence. The contact stated that days later the manufacturer sent a letter that the case was closed. The failure milea
formal complaint for gross negligence, warranty breach, and repeated mechanical failures involving my RAM 2020 ProMaster 1500 HR (VIN: [XXX] ). The vehicle remained out of service for 1 year, 4 months, and 18 days due to transmission damage. Five days after the final delivery, the transmission failed again. in addition, there is a persistent problem with the steering system. The dealership insist that this is the " Normal Operation ", but this is a defect according to the owner’s manual. The transmission is covered by the manufacturer’s warranty, and the supposedly replaced parts are covered by the GWC Warranty. November 14, 2025, the vehicle was transported to Miami Lakes Chrysler Jeep Dodge RAM to be inspected by Mr. Christopher Byrne (Bosch EAA, [XXX] ), the technical inspector assigned by Stellantis to conduct the evaluation. After returning home with the vehicle following this inspection, new oil leaks became evident, apparently originating from the engine. It has now been one month and ten days since my initial communication with Stellantis FCA, and I have not received a single official update regarding the status of my claim. Likewise, ten business days have passed since the inspection performed by Mr. Byrne, without any delivery of the diagnostic results, findings, or a corrective action plan. I appreciate your attention to this matter and expect it to be handled with the urgency and rigor required for a case involving mechanical safety risks and manufacturer responsibility. I look forward to your prompt response. Finally we have not received an effective response, and the vehicle remains inoperable at my residence.

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.

I, [XXX] , hereby declare under oath that I have been a victim of fraud, negligence, and unfair business practices by Ford of Kendall. On [XXX], I purchased a 2020 RAM ProMaster 1500 HR (VIN: [XXX] ) for $45,906, based on the seller’s claim that it was inspected, certified, with a clean title and under manufacturer warranty, and eligible for an extended warranty.” A CarMax report dated September 28, 2025, later revealed that the vehicle had been involved in a severe prior accident that was never disclosed, valuing it at only $5,500 and causing a loss of over $40,000. Since purchase, the vehicle has only been operational for about four months, spending the rest of the time in repair shops due to serious and recurring mechanical failures, including leaks, oil contamination, and defects in the steering, transmission systems and other problems. Check Google reviews by [XXX]. The alleged “repairs” were superficial, mechanical failures persisted, and invoices, service receipts, and technical reports were omitted, demonstrating a total lack of transparency. The vehicle represents a road safety risk and direct economic loss. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We were driving on I -75 near mm 224 when we felt the van kind of wobble then heard a noise like we dropped something. We pulled over, all four tires were inflated, so we looked under each tire, we noticed the tread was missing. We drove slowly about 5 miles, to the nearest tire shop, which was Devito’s Auto Repair 2420 US Hwy 301 in Ellenton, FL, who switched out our tire and recommended we change out the remaining three when we get home, as these tire are known to separate tread.
