Front parking sensor false alarm when stopped

I’m experiencing a recurring issue with my Purosangue’s front parking sensors and wanted to ask if anyone else has encountered something similar.

When the car is stopped—such as at a red light or in slow-moving traffic—one of the front sensors occasionally shows a red “closest object” alert, even though there’s clearly nothing in front of the vehicle.

My dealer has already replaced the affected sensor, but the issue still happens.

Has anyone else seen this behavior on their Purosangue?
Could this be a known issue or something related to software calibration?
Any insights or shared experiences would be greatly appreciated. Thanks in advance!
