Honestly, we've had hardly any issues with it... leaky tail light fixed under warranty, and this leaky screen and that's about it. Certainly never left us stranded, and just needed the usual maintenance along the way.
Here's a little show and tell -

Basically they ran Sikaflex right the way up the driver's side edge (where it was leaking) then put a big dollop in the channel at the top. That causes water to pool, hence the rust.
I'm livid... this is not an appropriate fix for what was a brand new car - and I have spent way too much time trying to hunt this down over the years.
