My vehicle is subject to open safety Recall 67C involving the cooling fan module and related fuse protection in the engine compartment. The recall has been open since October 2025. The manufacturer and dealer have confirmed that the remedy/parts are still not available and that there is no ETA for repair. At this time, I have not experienced an obvious operating failure with the vehicle itself. However, the open safety recall remains unresolved, and because no remedy exists yet, the recall cannot be completed. This is my sole work vehicle, and the unresolved recall is preventing lawful completion of the import/registration process in Canada and preventing me from using the vehicle for work. The problem has been confirmed by the manufacturer and an authorized dealer as an open recall with no available remedy at this time. I am reporting that the manufacturer has failed to provide a timely remedy for this safety recall.

My power steering locked up and almost caused an accident. The dealer said they are having trouble with this component (corrosion in plug). I have a fleet of trucks, and I just had the same issue with a 2023 model which I also almost lost control of the vehicle. This is a defect or poor design that needs to be recalled before someone get seriously hurt.

The contact owns a 2018 Ram Promaster 2500. The contact received notification of NHTSA Campaign Number: 25V720000 (ENGINE AND ENGINE COOLING). The vehicle was started, and there was smoke coming from the exhaust pipe. The contact was unsure if any warning lights were illuminated. The contact took the vehicle to an AAA location and was informed to tow the vehicle to a dealer for assistance. The vehicle was towed to the dealer, where it was diagnosed that the low-speed radiator cooling fan failed to engage as designed, causing the engine to overheat. Due to the overheating, the engine became warped, causing a coolant leak into the cylinder, and causing escaped gases to enter the cooling system. The contact was informed that the engine and radiator cooling fan assembly needs to be replaced. The vehicle was not repaired due to the cost. The vehicle was towed to an independent mechanic, who replaced the engine and radiator cooling fan assembly. The manufacturer was made aware of the failure. The failure mileage was approximately 32,584.

The rear parking brake pivot point gets stuck in the on position. After some research, this is VERY common on these vans and is going to cause wrecks or deaths. The pivot point where the parking brake connects to the rear parking brake linkage rusts and gets stuck VERY easily. My van only has 60,000 miles on it. There is no sensor in this pivot point, so when you release the parking brake, it seems like it is off—but it is not. No indication no warning.. Tire spun and van drove fine until the breaks failed. 100 miles down the road, my rear calipers were glowing red, which caused my rear parking brake to catastrophically fail, causing the rear tire to seize and almost leading to a wreck. Luckily, I had plenty of water on board to put out the rotor fire.

Hello, my 2018 Ram Promaster is exhibiting the same symptoms as recall 44A: metal debris in the transmission, which could possibly impact the parking pawl I believe. I have experienced transmission issues for the past 12 months and the Ram dealer in Carson city has identified the same metal debris as seen in recall 44A for 2019-2021 vehicles. I respectfully request that the Office of Defects Investigation consider reviewing this complaint and evaluating whether the scope of the recall should be expanded to include my vehicle. Thank you for your attention to this matter. Please let me know if any additional information or documentation would be helpful.

I was Driving down the highway at 45-50 mph when the truck suddenly the engine started to rev very high approximately 5000-5500 rpm and the truck lost all Drive gears. I immediately put it in neutral and tried again to put it in drive and nothing happened. I immediately pulled over to the shoulder and shut the truck off. I waited and restarted the truck but the truck did not have any movement in any gear. I had to get it Towed to a local shop.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
