I had NHTSA recall for this generator done (23E-030) which was to solve the same problem I just had. Apparently, they just moved to a smaller diameter fuel line to fit the fuel pump better. However, this hose also came off my Cummins generator fuel pump and was spewing gas all over the generator and the ground when we ran it. This is a very unsafe condition and I'm surprised, after the recall was performed by a certified Cummins dealer (verified by Cummins) that this "new" fuel line has also come off the fuel pump.

While driving Highway 95 in Bullhead City, AZ the awning deployed. I heard a very large noise and the BMPro making a noise as if the awning button was being pressed. I was in the middle lane of the 3 lane hwy and immediately pulled over to the right. My friend removed it on scene and put it in the van. 1. 12 Jan drove it to California. Turned in my van and awning to [XXX], Santa Fe Springs, CA on 13 January. I haven’t heard from the dealership but have a lot of email correspondence from the manufacturer, Thor. I don’t know what they did with the part. Mileage was 7,740 miles. I opened the awning once at my house right after I bought it. It’s never been opened since. 2. I could have been injured or died if it would have hit something or someone else and I would have been traveling at a higher rate of speed. Others driving could have been injured or died and at the very least a great deal of property damage. 3. I have no idea what Mike Thompson Dealership did when I dropped it off. My service advisor said they were going to have the local Thor Rep look at it to determine if it was under warranty. After service Rep told me this, I contacted Thor and described what happened and the lady said it was absolutely covered under warranty. I have been in email contact with Thor and have all the emails between us but can’t figure out how to get them in this report. 4. I don’t know when and if the local Thor Rep reviewed the damage. Dealership has not communicated with me. 5. Absolutely no warning this would happen. Like I said, as it was happening and when I pulled over, the sound of the awning deploying was coming from the BMPro. As a side note… this incident has given me PTSD feeling like I cannot trust that this will not happen again and that I might not be so lucky next time. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

While driving my winnebago Travato, we heard a sudden loud noise from the passenger side. We immediately stopped the van in the middle of the street, looked out the side and noticed that our awning was hanging off the side of the RV We turned on the hazard lights and went outside. Once outside, we realized the awning had completely broken down, unfurled, and was dragging on the street. One of the arms even broke in half and fell off. There was absolutely no warning whatsoever and we were in shock when it happened, especially since we were in the middle of a busy street and there were many cars around us.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Ram Promaster (passenger Single Seat) verdict →
