I bought a 2003 Audi A4 convertible in November 2008 and since then the defective convertible top has resulted in the rear glass window to be nearly completely loose. This is a major hazard and represents a danger since the window could fall out and hurt other people. Audi of santa monica said they can't/won't fix it and referred me to an upholstery shop who said they have seen this problem before and can't fix it (despite Audi recommending them for fixing this). A detailed check of numerous online discussion boards (in the U.S. and germany) shows that this is an extremely coming problem for 2003 Audi convertibles that Audi simply refuses to acknowledge. 2003 was the first year that karmann manufacture the roof and, interestingly, harmann in germany seems to accept some responsibility and has fixed this problem for some people, charging only for labor. I strongly recommend that NHTSA look into this faulty manufacturing issue and force Audi to accept responsibility for it.
