New Double Boing alert

[rgedad]

We have started to get a soft double Boing sound periodically while driving around. We are at or under the speed (typically suburb driving). This is relatively new sound. Not as nearly as frantic an alert as the 5 tone "Do You SEE that CAR" alert…

We are running with recently installed 2020.12.5. We have a 2018 MX 100D with a recent HW3 upgrade.

Seatbelts are attached, no warnings on any screen. Car seats in the back, but no kids, seats are latched, and doors show as all closed.

Any idea where to start to look??

Mine does this for false positives from the sonar (parking sensors). Why they trigger at anything over 5 MPH is beyond me, but they do.

Watch your display to see if the arcs around the car change colors in lockstep with the chimes.
