Windshield Wiper/washer Motor problems of the 1999 Mercury Sable

I own a 1999 Mercury Sable with all the bells and whistles. For the past year my windshield wipers turn on by themselves while I'm driving. My hands are on the wheel so it's not as if I'm setting them off. Have there been any other complaints like mine? what is the cause? is there a recall on this condition? thank you. D thank you .

Windshield wipers engage by themselves without warning startling the driver,they turn themselves off after a few swishes.

The windshield wipers turn on without the switch being turned on. This occurs randomly and can be aggravated when the car goes over a bump. Nlm.
