NHTSA Complaint #11510907 — 2016 FORD F-350

My wife and I were pulling a 40’ fifth wheel from AZ to Idaho. On the Montana side of 4th of July pass I suddenly get a trouble code. The exhaust filter is full. My wife and I are both handicapped so in the mountains pulling our rv scared us both. I pulled over when I could and called Ford. The guy tells me to just drive it at a constant speed over 45 and it should clean itself. My question was I’ve been traveling over 45 for miles so why is it full? No explanation, however, he tells me if it doesn’t clean out then the trk will go into limp mode and that’s not good. But also says we should be ok for the 200 remaining miles until we get to Idaho. Well here’s the problem. My understanding is that this component is part of the emission system and is not something that is life nor death if it isn’t working. Well we get part way up the mountain not fifty miles in the middle of no where and the trk suddenly starts loosing power on a two lane mountain pass with two handicapped people, one 70 and one 62. This trk slows to 5 mph in first gear and that’s it…. That as far as I’m concerned put our lives in danger! We could have died over a stupid part of the emissions system that Ford decided was important enough to put a vehicle into a not even a limp mode but actually create a dangerous situation. Why so they can charge me $200 to clean it. Which is done by hooking a code machine to the trk and telling it to clean the exhaust filter and it all automatic. I understand this limp mode and other computer controlled systems Ford and other manufacturers built into their vehicles allows them a way to get you into their shop but taking my wife and my life into their hands is not only dangerous but should not be allowed on such a level. If we would have been hit or injured because of this there would have been a law suit for sure. So now what????
