A hello to all Arona drivers. We got the first new Arona in July, here we had after 4 weeks, which one drove us on the back. Now on 16.08.19 we got the next new Arona and here we have the problem, that the windscreen wipers at the front as well as at the back do not function correctly. We drove at night the first time in the rain, the windscreen wipers rubbed over the disc, that was already very dangerous, because no clean wiper picture was created. The other day in the light I looked at it exactly, it was rubber abrasion from the wipers, this was very stubborn to remove. At the back of the disc there were also traces of the rubber, also that I removed for once. Unfortunately, I did not take pictures of it, I thought it would be done after the cleaning. Unfortunately, it was not, the problem bes tand further. I went to a Seat contract workshop, which made a film of the problem and sent it to Customer Service Seat. Here came in response, windshield wipers are wear part, because they can not make. Today I have attached a new wiper at the rear, the problem persists. Since someone of you had such a problem or knows such a thing from other vehicles?
