I don't consider it as a problem nor it bothers me but I'm just wondering, once in a while, the wipers wipe on their own even without rain sensed. Also happens for the back wipers. I would say they happen very occasionally. Anyone has the same "problem"? Will it damage the wiper blades?
I've searched the other forums and didn't find an answer. :confused:

Could be a software glitch? I will surely ask the dealer during my next service appointment.

I'm guessing this is caused by a dust buildup on the sensor or something. From Wiki:

The most common modern rain sensors are based on the principle of total internal reflection: an infrared light is beamed at a 45-degree angle into the windshield from the interior — if the glass is wet, less light makes it back to the sensor, and the wipers turn on.
So if something is on your windshield (be it rain, or dust or the palm of your hand), the sensor should initiate a wipe.

I think that all models do that occasionally... I treat it as a 'nervous tic'. Your blades will be OK. :thumbsup:

Make sense. Thanks Yazovets :)

I guess it's dust build up but I'll still ask the dealer during my next service and I'll post if I can get any info.
