   Gas tank connection from fill tube to gas tank has a bust on plastic gasket. Leaks gas near the muffler. No replacement part, only option is a new $1,300 gas tank that is back ordered probably due to this issue. I have two vehicles of the same year that are doing the same thing.

   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.

    As of approximately around the 15th of April 2023, we realized suddenly that our lithium battery in our 2019 Winnebago Travato was not being replaced with charging from our Volta alternator from driving or from our solar as it has always done. The KISAE DC to DC charger and the Volta system show an error message that they were/are ‘overheated’. Testing of the DC to DC charger shows that it’s receiving far over the correct voltage. Upon diagnostics at a RV dealership they found the alternator is being overcharged. The alternator must be replaced before it can be determined why the alternator is overcharging (since obviously safeguards are meant to be in place to prevent this). We discovered through online research of the NHTSA Recall ID Number 21V793 on Boldt 2021-22 and Travato 2019-22 with Volta Power Systems; Manufacturer; Winnebago Industries, Inc. Subject; Wire Harness Built Incorrectly; loss of over-current protection can cause the wires to overheat, increasing the risk of a fire. There was also another subsequent recall for Winnebago Travato 2021, Winnebago Boldt 2021, and Storyteller Overland Vans 2021 of the seemingly same exact issue again, “In the case that power connections are not properly seated severe voltage spike by intermittent connections could damage the filtering diode in the the alternator control harness (10001447) resulting in the possibility of a shorted wire, on the same circuit the order of the fuse and diode were reversed. In the case that the diode is broken in a closed condition, the sense wire could be shorted to ground resulting in an overheated wire or broken wire. The identified cause of the diode failure was excessive overvoltage spikes. When the diode failed, it failed closed and with the diode and fuse being reversed the wire continued to heat up instead of breaking the fuse. With evidence from our van I believe in a strong probability the scope of the recall should be widened to include more units, such as ours. We are proof

    Driver's side exterior mirror design flaw/failure. Safety of self and others at risk due to lack of visibility in checking for clear rear and lateral traffic. Mirror shakes uncontrollably and or is unable to be adjusted for proper viewing of rear and lateral traffic. Many warranty claims have been submitted through dealerships as well as various online complaints having been issued. No in-dash warning lamps or messages would appear for this type issue. This issue appears to be affecting driver's side mirror only and not passenger side. Symptoms of driver's side mirror failure do exist in various stages prior to overall failure. Considerable mirror shake and inability to keep mirror adjusted due to such shake. Problem has been ongoing with some reports having detailed up to 3 changes of driver's side mirrors by dealership for single vehicle.

    LT225/75R16 We started experiencing very noticeable vibrations when driving at highway speeds. We brought the van to our dealer for service and they responded "Please replace at least both rear tires. Right rear seems to have ruptured internally?" "Please replace that right rear tire asap." We had the tire removed and you can see the attached photo of the inside of the tire where something has obviously failed. These tires only had about 17,000 miles of use. I still have the bad tire.

    During some cases of downhill driving, the Brake system warning light will come on. I believe this issue is tied to a combination of longer and steeper downhill drives when the angle indicated in road side sinage is no less than 6%. Minimal braking ton control the decent is used. Each time this occurs, I take the nearest off ramp to pull over to a stop and turn off the engine. My visual and hand-test of each wheel/tire temperature finds in my opinion, the temps to be quite nominal. On the last trip, a digital laser thermometer also indicated a good balance across the four wheels/tires, with no issues to be concerned with. Under the hood, the Master cylinder, ABS controller, Power Brake unit, brake fluid vessel and brake lines were all cool to the touch. Brake fluid in the vessel is clear and full. Each time the engine is restarted, the warning light is off and the drive can be continued with no further incident unless a similar long and relatively steep downhill is encountered. Time of day and outside temperature seem to not matter. Safety is compromised when I cannot trust that the warning light is, or is not indicating a real problem Reference RAM PROMASTER 3500, VIN [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

    Vehicle Electronic throttle control had a malfunction and system went into limp mode on a highway at highway speeds of 70mph. The engine destroyed itself instead of limping. Lost power and almost got hit by a semi truck and other vehicles when this happened. Ended up getting a used engine due to current remanufacture costs etc. Total cost out of pocket because the dealership lied about my warranty and what was covered and for how long was around $7,000 parts lanor etc. Limp mode is dangerous and the way it happened on a highway could have gotten me or others seriously hurt or killed. Also now there is an electrical error code P0482 which is electronic coller fan issue other rams are having. All vehices in this series that have the recalled fan should be included the 2018 has issues but no recalls but has the same components of other recalls.. doesn't make sense.

    The 2018 Ram Promaster 1500 appears to have a manufacture defect with the Engine Coolant Reservoir bottle. Based on my research and due to the lack of national shortage of the OEM coolant reservoir replacement (even after market are out of stock), the reservoir has a soft spot on the tank which allows coolant to leak. The leak appears to be in the same location/spot with my leak in conjunction with others who are experiencing this issue.
