On a continental trip last summer, the doors on my s3 started to rise up out of the hinges above around 79mph, the top ones even when the straps were all done up. This resulted in some panicked octopus moments pulling over and holding everything together. I was surprised, as I thought the heat (30 degrees+) would have made the brass fittings expand rather than contract The issue was solved using some twisted wire around the hinges in a figure of 8 pattern, and are still on there now (albeit an ugly fix). Has anyone else experienced this phenomenon at all, or is it just my car with these characteristics? Matt
