My 2008 Corsa 1.3 D Breeze has had the wipers go out of alignment after freezing up - admittedly it was my fault as I thought they were not frozen. Basically, the drivers-side wiper hits the front screen pillar and comes to rest on the top of the bonnet. The car is still under warranty but my local Vauxhall dealer states it does not fall under the warranty terms as it has been changed by Vauxhall.
