NHTSA Complaint #11633031 — 2019 FORD F-250

transfer case is shifting from 2 wheel high to 4 wheel high while driving down the highway. it does not engage the the 4wheel drive front hubs when doing this so no indication this is happening. eventually the shift fork breaks and transfer case is then either locked in 4 wheel high without knowing or the transfer case goes to a neutral position and loss of all power. in the my incident i was driving on the interstate and transfer case went to neutral without warning. i was in the middle of 4 lanes of traffic and total loss of movement. i was able to navigate the truck to the side of the interstate safely. however had this been in the middle of rush hour traffic this would most likely been a fatality report with multiple cars involved. After discussions with ford techs i was advised this is an ongoing issue that has not been addressed by ford and they are seeing more and more of these issues, so much so that their transmission techs are backed up for 3-5 weeks with these repairs. seems to me this kind of failure nhtsa would be very aware of and demanding a recall be issued to fix this issue. rather the owners are eating the cost of repair for a blatant safety issue being over looked.
