I recently purchased a 2019 f150 lariat. Multiple times I have woken up to a message from ford pass stating my truck has disconnected to save energy. I go out to my truck and it’s dead. I have taken it back multiple time and they replaced the battery but say they are unable to reproduce the issue. It usually happens after I see this alarm when I’m getting out of my car. I don’t know what causes it. Anyone have a fix or idea as to what is happening. I love the truck other than that but I feel like I’m going to have to lemon it if they can’t figure it out.

 

It's known for some of these trucks to have problems with parasitic draw, but it seems like whatever place you're taking the truck to is giving you the run around.

Any aftermarket accessories?

 

I just posted a discussion where I ran into a parasitic draw and had to spend some time trying to figure it out. I eventually did and you can check it out to see if this is the cause of your draw. My post was just mine however but it could be yours too.
