Engine won’t shut off

[Dan Larsen]

The engine on my 2018 F150 Raptor won’t shut off. When I press the start/stop button, everything goes through shut down mode, except the engine keeps running. Press the button again, everything boots up just fine and it drives fine. The error message on the dash screen says “Lane Keeping Sys Malfunction Service Required.” Disconnected the positive and negative battery cables, it still runs. Any ideas on how to turn it off?

Maybe fuel pump fuse.

Thanks. As I was getting ready to pull the fuel pump fuse, it just turned off by itself. Not starting it until I drive it to the dealership tomorrow. Gremlins?

Hope it’s an easy fix - good luck.

Dan...make sure to get back with whatever the fix is. Thanks.

That's a weird one, must be ignition related somehow. Can't wait to hear what this is. This is definitely a major safety issue. Wonder if it would shut off if you walked away from it.

The most common cause of this concern is aftermarket equipment, typically wired into the BCM, ignition circuits, or PCM. Do you have any aftermarket components?

This is going to be interesting, please keep us posted

And yet another reminder of why I always avoid “technology for technology’s sake” - in this instance we have an example of how push button start can cause headaches while not delivering any real improvement to the driving/vehicle ownership experience!

curious what it the issue ultimately proves to be.....but I’m guessing it has to do w/ that

Any update on this? What ended up being the problem.
