Electric system went down, no lights,turn signals,horn wipers, etc. (radio kept working) engine started and drove home very carefully.
Truck experienced multiple sensor failures over several months that reset. Failures include car stalling in intersection, blind spot monitoring, back up sensors, car shutting off and turning back on on its own. Car had to be powered down and shut off for 30 seconds before being allowed to restart. Most recent failure resulted in truck horn going off as well as car turning off while going 35-40 mph then restarting on its own - car surged forward after it restarted itself. At the same time hazards coming on, doors unlocking and locking and rear tailgate opening. After bringing car to a complete stop, shut off car and it turned itself back on (horn went off, hazards went on, doors unlocked and locked, and rear tail gate released). Towed to dealership for repairs and they were unable to recreate the problem.
Horn not working. I purchased a brand new 2016 Ford F-150 in 2016. I am the first and only owner and I noticed 2 days ago my horn all of a sudden stopped working when I press on the horn but it will sound when I hit my alarm button on my key fob. The vehicle has not been in any accidents, I checked all the fuses and they are working and have a current running through them. After some research (within google and F-150 forums) a lot of people are having issues with this and having to replace their clock springs.
