Need a little input. How is the determination made between "design flaw" and "safety recall"? I am the owner of a 2009 Tiguan, love to look at it, honestly afraid to get in...... I feel that black mold from a drain "design flaw" is a safety issue. I also believe that when the fuel door will not open, that becomes a safety issue when stranded. Received an estimate of approximately $1500 for the roof drain repair from VW dealership even though they admitted it was an ongoing problem, reaching much further than the 2009 model year. Does this not seem ludicrous to anyone else? Thanks for any input.
