Alarm goes off for no reason, anyone else see this?

[mark Haasser]

On my 19 Limited max with 301A package the alarm will trigger for no apparent reason. I can't really make a correlation of any kind with temperature change, high wind, or change in atmospheric pressure. On one trip I could not get the indicator saying the hood was not closed to go away, but that was right after I checked the oil months ago and I have not seen it again. Has anyone else seen this? Is there a way to get the exact cause of what tripped the alarm? All I get from the Fordpass application is intrusion detected. If I could see what sensor was having an issue that would help narrow it down. Thanks for any help you may provide.

Most people attribute it to bugs inside the car.

I had this issue this summer for the first time since owning it, since June 2019, when staying with my parents at their cabin. Went off in the middle of the night about 3 times in 20 minutes. I didn't notice it but in the morning my dad asked what happened and I didn't know. I looked in the Fordpass app and sure enough it showed intrusions. I went outside where it was parked and didn't notice anything. I thought, huh, now I've experienced this phenomenon that others have posted about.

The next night, same thing. So in the morning I went and looked again more thoroughly and lifted my kids booster seat and found an acorn under it, which is not normal. I also popped the hood and on the engine cover were a bunch of broken acorns and crumbs. So a mouse must have been checking out the sweet Expy for a new hangout spot and got busted.

One item that will set an alarm on a microphone equipped vehicle is a plastic water bottle. A temperature change will cause them to crackle which is real close to the frequency of breaking glass.

Bunches of threads on here...here’s one:

Bug in the cabin, water bottle, squirrel, aliens...ya know, anything moving around or making noise in the cabin would cause this. Good luck!

Add rain from a vented sunroof to the list.

It's mentioned in the linked thread above, but have you tried changing the setting after turning your car off from motion to perimeter only to see if it still does it?

It happened to me many times due to a bug, moth flying around. I even disabled the all perimeter alarm but my XLT still went off at night

Have not had that particular gremlin. My gremlin randomly opens the rear lift gate.

Yes, the alarm goes off. I had a family of mice move in. That's what I found! Treating the problem with Decon. The green squares. They have been eating it up.
