This is a long shot. We bought a model 3 Tesla three years ago. In the last year it has started to leak really badly when it rains with up to over an inch of water in the rear footwell. Our car has been back and forth to the garage 4 times over the past 6 months - we have barely had it at home during that time. It still leaks and it is still at the garage as I type.
The people at the Tesla garage told us (verbally and off the record) that they had had 10 cars in with the same problem, all from the same factory in Berlin, the same age and with the same trim.
Has anybody else out there had this happen to them? I am worried what will ahppen when the warrantee runs out.
