Just today, the inner drivers side sensor is sometimes giving sporadic warnings (red indication, so = it thinks its very close). Nothing there. It's so loud I think it's a dangerous distraction when driving. Sensor is clean, the connector at the back seems well pushed on.

Sometimes it works fine like the rest of them ; detecting closer and closer obstacles with greens than finally a red warning/ sound. Any ideas/ experience about this ?

For an aid like this to make driving more dangerous when it malfunctions, it makes a mockery of Volvo's reputation for design for safety. Better surely that the default should be an error message, not an alarm.
