F150 alarm issues

[badluck]

So I’m running into an issue with this pos f150. This is the second time now. When I park it in front of my house with my dump trailer attached the freaking alarm goes off every few minutes. I’ve disconnected the trailer and wiring but it still does it. If I leave it unlocked it won’t go off but this is Ca. You’d better lick your shit up. When I park it in the driveway this doesn’t happen. I was working in SF this week and 3 times I noticed the truck was unlocked. I’m positive I locked it. Wtf? It’s a 2021 f150 pos. I miss my 07 250 base model 6.0 it was a beast even at 340k

Perhaps you should try attaching a boat trailer...

Went through something like this with my friends 2019 Raptor. Same deal with "ghosts" un locking doors, but the pisser was when it went into anti theft, and wouldn't start. Dealer had to do some kind of reflash on the pcm or bcm? Weird crap!

Rule 1 Never address RDP tow vehicle of the millennium as a POS…….

SSM 49601 - 2021 F-150 - False Activation Of The Anti-Theft Intrusion Alarm System

Some 2021 F-150 vehicles may experience the anti-theft intrusion alarm system activating when there is no evidence of an intrusion. This may be due to the intrusion alarm system sensing vibrations that are characteristic to other vehicle systems. To correct the condition, update the body control module (BCM) to the latest software level using the appropriate scan tool. After BCM reprogramming completes follow the on-screen prompts to relearn the TPMS sensors. For claiming, use causal part 15K609 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

APPLICABLE VEHICLES
2021 TRUCK: FD P702N F150

I’m going to bring it into Ford. Thanks for all the replies. Ive been locking the doors manually and that might be working

Possible trade-in alarm? J/K

Hope they can resolve the issue. Almost like the customer is beta testing new vehicles for them these days.
