I have a 2016 f150 xlt 5.0 4x4 . Other day after driving for 60 kilometres (Canada) I came up to a stop sign . Went to make my left turn and nothing ... She had stalled . Put in park , shut it off and tried to start it again . Nothing . Wouldn't catch . Pushed it to the shoulder and called my salesman ... (Truck is only 2monthes old with 8000k) he tell me what I know ....roadside assistance blah blah bah . Get off the phone with him and try it once more and it goes . Perfect. No codes thrown at all through the whole process . Next morning back to work I go and make an appointment for that afternoon . On my way to the appointment check engine light comes on . I'm happy . Get there they check the code and its pointing to my interior fuse box . they called it a something something module and the service guy said interior fuse box . Great get one and put it on . He proceeds to tell me that they are on backorder and their is none in North america. Nothing I can really do but wait I guess and hope nothing else happens .... This all happened yesterday and today . So tonight I'm going to get gas and the horn starts blowing wide open ...... Can't get it to stop . Had to pull over disconnect the battery .. Stopes ... Wait 15-30 seconds , curse , touch the wire back to the pole and it's going off again . I had to get my arms through the grill to disconnect the harness on the horn to get it to stop ..... Just curiouse what anyone has to say on this ... If they can't get the part to fix it ... Do I ask for a new one. I'm gonna take a wild guess and say no one has heard of anything like this happening. What yas think
