Hi all and greetings from Finland!
Just recently changed my Seat Leon ST
280 into
Cupra Ateca and been enjoying this hot mess for a couple of days.
What I've noticed that the back passengers doors both accumulate quite alot of gravel into the different crevices in the door, although driving on concrete. Is there any quality improvement campaign from Cupra for this or any other fixes available? The gravel, mud and snow must make heavy damage on the chassis and rust will appear there 100% if not fixed.
It was a complaint by some with their first standard Atecas back in 2016. It's how the door is part of the wheel arch. Some cars have that design. Allows more space in the rear by pushing back the rear cabin into the rear wheel arch. It's not the first VAG car with this design.
If you are getting dirt past the seal you might need some remedial work. I'm not totally convinced Seat didnt roll out a fix for the seal issue way back in 2016/17. Now it should be sorted in general. That leaves stones etc to get into the integral fabrication on the edge of the door. Cleaning, it's regarded as good practice to wipe over that edge (you see a drainage assembly gap, like a vein) and dislodge any stones that get into that edge assembley. I haven't come across any posts that have found rust created by the rear door design.
In the end you get use to living with the design. Elements of the standard
Ateca board were up in arms about it at the time. The Spanish
Ateca board, some members were filling the gap themselves, not recommended. This is where I have a feeling that Seat might have released an early fix some seven years ago. If you are getting more dirt in one side than the other beyond the seal I'd raise it with your dealer as an issue.
I've only really had a noticeable issue once where red sandstone mud got past the seals. Open farm gate leaving red mud on the road as farm equipment left from ploughing a red sandstone field, red mud on the road. That got past the seals and appears as red dust when dry. Obviously I went looking for it.
