I am currently going through this with my wife’s Bronco. Lit up like a tree, parking light is flashing, engine start/stop button flashing. I disconnected battery and waited and still not wanting to start. Got someone to jump me and nothing happened…….waiting for a tow ugh

Hi there. Can you send us a DM with your VIN and dealership info? I can look into this for you.

I eventually pushed and held the start button after a while. That seemed to reboot the system and the Bronco started. The dealer reprogrammed, believe it or not, the entertainment system. That has worked

My Dealer is: Family Ford

the dealer was very helpful and accommodating. Provided a loaner car from the time I took the Bronco in 03/12
until I picked it up on 03/14.
You need to highlight the Ford Motor Company avatar (post #5) and select "start conversation" to give them this information.

Update: I had the car towed to dealer. The car miraculously started for them and they found no error codes and everything was fine. I drove the car home and then the next day it died again and I had all sort of glitching lights and weird chimes. Could not get it jumped and now it got towed again to a different dealer to see if they can find anything. I’m thinking there’s a short somewhere

That's horribly frustrating.

This is usually a sign of a weak/discharged/bad battery. Charge the battery and see if that fixes it.

You'd think the battery would be just fine if it's able to flash lights and turn on/off the dash!

I'm assuming you are going to show the service advisor this video.

The electronics that run the car are pretty sensitive to lower voltage. While everything lights up, that does not mean that all other systems have the power they need to function properly. Several people here who drive infrequently or drive very short distances have had issues with the battery getting "weak". Sometimes, once they start a routine of charging the battery when it is parked, the issues they have go away. To me, the primary symptom seems to be that all of a sudden there are a lot of error codes/lights that don't seem to be connected for any reason.

Still amazes me that a weak battery can flash headlights on and off, along with dash indicators. Seems silly that this would be allowed to take place on a vehicle that determines the battery is weak/low.

Kind of like describing to the doctor that my arm hurts when I twist it. The response is that you should not twist it. If the battery is weak/under charged, then don't provide actions that will weaken it more.

ChatBS is being rolled out in 2028 that will allow the vehicle to think better about what it is doing and avoid these situations.:blush: Not long after that, all vehicles will begin culling their drivers and passengers. :frown:
