I just mentioned this again to my wife this morning. She stayed in the truck with the A/C while I got out to go into the pharmacy and get a script. I forgot the fob on my belt and when I shut the door I got the 3 honks. I have been through every page in my Uconnect settings a bunch of times and there is no way to disable it so I'm stuck with either having it honk, leaving my key in the truck while it's running, or shutting off and restarting the truck - which gets old after a while and wears on your starter when you're getting in and out frequently to go through gates. Or leave the door open when it's raining.
