450 nx doesn't always beep when locking
 

Anyone have any issues with this? I notice that sometimes when I lock the car that there is NO beep. I have the mirrors set to auto fold when locked, so I always double check the mirrors to see if it locked. I asked the dealership and they said that it is a known problem but there is no fix yet (BUT my local dealership doesn't seem that familiar with the car so hasn't been much help). Has anyone out there had this problem and figured out a way to fix it? Tia!

Mine never beeps! Only when I press lock twice does it beep. I think I set it that way or maybe that's how it came...don't remember. Have the folding mirrors as well, that's usually a good way to tell. No beep beep beep chirp chirp chirp for me, are you sure you locked your car?...beep beep beep beep lol
