I'm having the same issue with a 71 plate crossland that I bought September 25. It only happens in wet conditions at around 55mph when going into 5th gear. In that period the car has been back for at least a month on and off where the sensor was replaced, then the clutch with another new sensor and still the release clutch message appears under the conditions above. The car is under warranty luckily but the still have the car and can't figure it out. I'm at the point now where I'm fed up as I have a car that I cannot drive above 50mph with out the problem occurring. I have said to them if there's no resolve I am wanting a refund or an exchange for another car. If they can't figure it out who can ?
