Rapid beeping at ignition off (1 Viewer)

[SethGX]

Last week I drove home from work on a nice clear afternoon, nothing remarkable about my 25 minute drive at all. After backing into my garage, I put it in park and turned off the ignition. It turned off, but immediately starting a fairly rapid beeping coming from the center of the dash. There were no error, warning or any other messages on any of the screens. I turned it back on, started fine, still beeping. I drove back out of my garage, all normal except, still beeping. Back into the garage, park, back off, still beeping. Got out, locked it, still beeping. Unlocked, got back in, still beeping. Got my OBD2 reader out of my glove box and was getting ready to hook it up, the beeping stopped. I'm going to estimate that it beeped for about 3 or 4 minutes. I went ahead and hooked up the OBD2 reader and checked for errors, but it showed nothing was logged. I did video record most of it in case I needed to show my dealer, but I wanted to post here in case anyone else has had this happen. I've driven it many times since then and it has not happened again. Hopefully just a really weird fluke.

I just had a similar situation, driving back from LA to SD, 20 minutes into by drive, the beeping started, from the same center dash position you described. No warning or messages, it beeped for the entire drive back, 2 hours. I even pulled off the freeway, parked, shut the car off, locked it, walked around the car and checked the sensors front and rear, and underneath the car, I could hear the beeping if I put my ear to the glass of the door. Did this 3 times, didn't work, just decided to complete the drive home and take my chances. I, too, did a video to show the dealer, where it's been for 3 days, they have no clue yet. One item I did notice, my dash cam, the green light that's normally a solid green while driving, was blinking green when this was occurring. I did stop beeping 10 minutes after I got home.

Dealer said they have no clue why the beeping would be connected to the dash cam. I have a 2024 Luxury +, with 10,500 miles.......

I had a massive headache by the time I got home.

Did you ever figure anything out?

No, I never figured out what caused that and it didn't happen again.
