Anyone else have a problem with a bad NOx sensor on a new truck? My check engine light came on around 8000 miles. Called the dealer, told to dive it until I get somewhere I can take it in. Was driving across country pulling a gooseneck with an excavator. Took it to a dealer in Lubbock and they said bad NOx sensor and parts are a month out. Keep driving it. Around 13000 miles and calling 10 different dealers took it to a dealer in Redding California. They diagnosed it as the NOx sensor and have no idea when parts will be available. Another dealer told me the part is being redesigned and it's unavailable. So I'm almost 100% positive the truck hasn't regened since the light came on and I'm starting to notice a hesitation and slight lack of power. It's got 14500 miles on it now and been two months since the problem started. I'm actually sitting at the dealer in Redding while the look at. Very frustrated with ford at this point. This truck was purchased for and used solely for work and so that I wouldn't be in shop all the time! Any suggestions?
