Hazard lights flashing

[Simplejack]

Anyone have this prob? My 2018 802a tech package with 2200 miles on it, I drove to work today parked at 6am and approx 12 hrs later 6pm I noticed my hazards just started flashing. not sure how long they were doing that. I did not have my keys on me they were 30 yards away in another room all day. Any way I grabbed my keys opened doors, closed em, locked truck with key fob and it started right up with key fob. Only thing I found on internet was low battery voltage on ford truck forum from 8yrs ago. This happen to anyone recently. thx in advance

Any chance a tow was attempted? I bought a new floor jack a few days ago and was testing it out on the truck, almost as soon as the rear tires lost contact with the ground the alarm started screaming.

no it was just sitting there not doing anything in a gated parking lot I dont have any mods on it, iam bone stock. drove it home this morning and didnt have any problems. maybe just a CPU glitch.

Any updates on this ?

 

[Simplejack]

nope, it was a 1 time thing. unless it has done it and stopped when I was not around. No resolution and no issues since.

Did the truck sit not driven for a week or longer before this short trip?

 

[zombiekiller]

did you notice that they started flashing with no sound?

Does your horn work?

Is it possible that your alarm had been going off? I ask this because if the alarm is triggered, the horn will stop honking after awhile, but the lights will continue to flash.

interesting, i was at work yesterday, truck had been parked for maybe a half hour and i got a call from someone that it seemed my hazards were on. I went outside and saw it but the hazards were not turned on but the truck was still blinking. Turned off once i unlocked the truck.

Mine just did the same thing at 4 in the morning.

Neighbor just knocked on the door.
My truck was flashing hazard lights and just about every other light on the truck. No alarm ever sounded.
Truck had been parked about 30 minutes before the lights started flashing.
Does anyone know why this happens?
The internet has many F150s experiencing the "flashing" but, no reasons for it.
