I am certain that I have read of Grenadier windscreen wipers turning themselves on and the driver not being able to turn them off. I have just had (am having) this issue myself. Did anyone experience the same and find a fix for it (I have tried a couple of times turning the car off and on again without success)? I have a feeling that I have read of this problem on the forum but my search has not turned up where I read it. I have spoken to my dealer and they diagnosed (remotely) that it was a control module failure and that the solution would be the vehicle going into them and a new module being substituted.
