Volkswagen Tiguan 2012: Lots of problems while under warranty

Like many of your readers I am similarly aggrieved with the evasive tactics of VW in regard to my Tiguan. The car is still under warranty fortunately, as it has been plagued by problems. Initially, it was an ignition switch that required replacement, then it was a recall for an exhaust emission sensor replacement, after which they found the need to fix a fuel leak to prevent the threat of fire. Most recently I had new tyres fitted at 43,000 km, as I believed tyre wear was causing road rumble. The new tyres did not fix the problem and eventually it was discovered that a nearside wheel bearing was faulty and the offside CV joint seal was leaking. I have six months warranty left and I'm not confident about future trouble free motoring. There seems to be a lack of communication and an unwillingness to keep the customer informed about these issues, and I find that quite concerning. I can't believe that such a world-renowned company could be so defensive when one of its products doesn't meet their normal high standards.
