Mine too!
I put it down to the fact that the dash materials and construction are poor, especially for an expensive hatch. Frankly a cheaper Megane, Focus or even something like a Fabia has a far better feel, fit and finish than any of the Altea's I've seen, mine included. If I had one major complaint about it this would be it - I have seen current shape Leon and Toledo owners being put off a new Altea, Leon or Tollie because of this and compared to the nice slush moudled dash of old I don't blame them. Sadly the heating/defrosting/demisting are also woefully poor for a modern car - not only has my Sport TDI not got heated mirrors (the much cheaper Cordoba I had before did!) but it takes an Age to heat up and clear on these frosty mornings. Not impressed!
