Rear Window Wiper Washer problems of the 2003 Volkswagen New Beetle Convertible

Rear window is detaching from convertible top creating open space into car, rain entry and poor visibility thru rear view mirror when water is coming in. Fabric shrinking back from glass. Cannot be re glued. We have been advised the entire top must be replaced. Researching this on the internet as well as with a company that replaces convertible tops evidently his is common on the 2003 model. The rear convertible top window started falling out late 2008. I bought this car new and the warranty has expired. Too many safety concerns driving in bad weather.
