Water ingress
But I have had two ingress problems within a month.
One was pinpointed to a defect in the seal around the A-pillar (where the roof connects to the windscreen) and this was fixed under warranty
But now I have a damp passenger footwell which the engineer cant pin-point to anything. He checked the drainage channels (clear), seals (fine) so he dried out the carpet, did a water test, kept the car out in the rain, did a water test again and all good. So why was the carpet damp in the first place?
Am I missing something?
Its probably only condensation from the windscreen (when I am clearing the screen and the air flow flicks drops of water onto the seat/carpet) or from the AC vent.
The engineer went over the car again and again and water tested it 3 times over 4 days and was not able to recreate the leak.
The A-pillar seal replacement was a defect and replaced under warranty.
This is not the seal around the glass portion of the windscreen.
This is the actual rubber/alcantra section on the inside surface of the A-pillar right round the two pillars and across the back of the windscreen.
A good 4 day job and then car in the paint booth to dry off under heat and then all the bits go back on.

Edited to add: I went to the garage to look. Although I've only had the car since the beginning of September 2020, it sat at the dealership for over a year (!). Nevertheless I didn't think it would have any issues. I've never driven it in the rain (and we've only had a couple of days of rain in Southern California since I bought it). But I was wrong. There is debris circling the drain. I will clean it out when I find something that can get into that space.
