2018 RAM Promaster

Vehicle is experiencing misfires code P0300 and P0302. Performed the usual repairs listed: 1. Coil pack, 2. Spark Plug, 3. Injector. Inspected cam, rocker arms and lifters. All checked good. Codes still remain. After further inspection, the exhaust valve is cracked/broken on #2 cylinder. This appears to be an issue as many others are experiencing the same problem. This vehicle only has 86k miles, oil changed at scheduled intervals.

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.

-Vehicle shut off on highway, lost power steering Vehicle fan sounds like it's running full speed after turning off engine. Turning key off and pulling out did not shut off engine. Engine appeared to be overheating. Electric system was making lots of clicks and odd noises. Power steering pump went out in intersection. Police helped push van out of traffic.

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.
