I took delivery of a Xcellance 1.4 EcoTsi 4 days ago and have discovered a fault in the design which will unfortunately lead to premature corrosion. Even though the vehicle is spotlessly clean on the outside, on opening the rear doors I noticed that dirt, grit & mud is collecting near the bottom on the inside of the doors. The channel where debris collects is formed by the way in which the lower black plastic door trim is attached to the door panel. On the majority of vehicles, the rear door is separated from the wheel arch and therefore this problem does not exist. However, on the Ateca, the lower part of the rear doors are directly exposed to spray from the rear wheels & tyres. It appears that this problem affects all models. Having been involved in the motor industry for many years, I would advise that you check your vehicle and if any dirt is collecting in this area then please help all Ateca owners by writing (with photos if possible) to your dealer and also to Seat (this can be done by searching 'contact us' on the Seat website) . The more of us who do this, the sooner a fix will be available. In the meantime I suggest that owners take the time to keep this area clean until Seat comes up with the required fix. I would have posted some detailed photos but unfortunately I need 15 posts on this forum before I am able to do this. Thank you for taking the time to read this.
