Does anyone have any experiences regarding corrosion of SRS sensor? If so, what are the possibilities of this happening?

Our manager's CRV, around 1 year old, was charged 31K for the repair of the SRS sensor. Honda didn't cover it with the warranty because they said it was corroded. I was like WTF? How can the sensor be corroded? Can this happen when you spill water or coffee inside your car? Does this mean all CRV have a design defect? Since it is a company car, our company shouldered this expense, but I will convince my uncles not to buy CRV or Honda for the moment. Service is very very poor.
