The tensioners have an over centre action and my dealer, Mike Duncan, feels that they can put too much pressure on the screen header rail. The factory's get out clause will no doubt be incorrect removal or fitting of the hood.....did you follow the handbook instructions?
The factory cannot refuse to cover the screen just because of the age and mileage of the car.....the warranty is for 2 years!
