Front "Park Aid Sensor" pops on at Stop Sign/Stop light randomly

[rvlasek]

Anyone have had Ford Fusion Hybrid "Park Aid" Sensor come on randomly stopped at a Stop sign or stop lights with no cars or obstructions near. This has Just started in last few months, have had vehicle for now 3 years. Dealer at recent maintenance service, could find nothing wrong. I have switch off since sensor alarm is loud and annoying....

Mine occasionally comes on if there's dirt or snow blocking the sensor. The alarm only work under a certain speed, so that's why you'd only hear it at a stop sign or light. Make sure your front sensors are clean and see if the sound stops.

Like jsolan, we usually experience this in winter when road salt/spray causes additional build-up on the body of the car.

Same here, when the car is very dirty (typically during winter) the front sensors can go off for no reason at low speeds or at stop lights.
