I have a 2016 f150 with the auto start stop. When is apply the brake , the truck shuts off as it should.The problem is after about 30 seconds my dashboard lights all start flashing, my navigation screen goes into "battery saver" shutdown mode, and the truck will not start back up when i release the brake. It does this about 8/10 times. I contacted my dealership and they told me it has to be doing this when i bring it in, problem is there always backed up a few days before i can get it, so they told me they won't even touch it if it's not doing it when i arrive. Now it did it again today, and i have to parking lines on my backup camera. Like i paid 50k for a truck that's driving me insane. Any ideas? The dealership won't put in any effort....

 

bad battery or short trips that are insufficient to charge the battery? alternator?

start the truck and turn off the auto start/stop. go for a nice drive without turning it off. i think it is 45min or 1hr to fully recharge the battery, if everything is working right. see if that solves the issue the next time u start the truck and leave the auto start/stop on.

 

Battery management system won't let the truck shut down if the voltage is below threshold.

 

Not much help here, but have your cell phone ready to record video of it happening?

 

lol that is why i had ? after. was just throwing out ideals.

 

take a video, contact the ford customer service people and/or try another dealership.

 

Usually it says "vehicle charging" on dash and the feature is disabled, if there isn't enough juice to run the feature...this is frustrating..

 

been driving two weeks straight with it off lol to work and back is an hour each way , highway no traffic

 

Finally found a dealership that will look at it, hopefully they can diagnose it! It's a step anyways! Lol

 

Bump on this. Took it to a different dealer, they took it for a road test, said no codes came up and everything worked as it should drive it home, put my foot on the brake, engine shuts off as it should, 30 seconds later, release the brake and it doesn't start up...about to drive this thing off a cliff
