I've read about some here in the past, but had an odd situation 3 days ago. I own a 2010 bought used in September. It has been perfect until I started the engine a few days ago. Wipers came on. I thought I may have accidentally hit the switch, but it was off. I turned the ignition off and restarted 3-4 times with no change.
I decided to try other electrical's for function. As soon as I turned the lights on, the wipers stopped. It has worked normally since.
