VW Emissions scandal
For me, it's obviously a big dent into the economy and such a large and iconic company, plus, Audi's and Skoda's are also affected. I see a wealth of VW's every day, and to read that they're violating emissions laws willingly is a bit sad to be honest. And I also didn't see it coming from such a large company like VW.
However, it seems like the press are really getting a field day on this, suddenly Mercs and BMW's and a multitude of different cars are supposedly violating emissions and fuel economy rules and regulations. Specifically, AutoBILD published an article on how a BMW X3 also violated emissions, they've since clarified the article. There are a few reasons on why BMW and other carmakers' situations are different from VW, but I'll let you guys research that. Anyways, my opinion on it is that press like AutoBILD really should be punished for false titles and statements. Their article that earned them publicity dropped BMW shares by more than 6%. I don't think AutoBILD and other press/news companies should be able to get away with irresponsibly damaging other companies' reputations, but they have done for a long time now.
