Shortly after delivery of my car in Late October last year, we noticed a rattling noise coming from the headliner close to the front driver visor area. We took it back several times and eventually they fixed it. Only shortly after the noise came back but in a different area - headliner above the front passenger window area - you hear it only once you go over a rough bumps - still very annoying - I shouldn't be experiencing these problems in a car that is just over 6 months old. I thought my car was unique in this regard. However, we received a loaner early this year and detected a similar noise elsewhere in the headliner area. Now we have a new loaner car and once again, it has a headliner noise issue. So far for me, 3 out of 3 Tesla Model S cars I have driven have had a similar issue. I hope they fix it once and for all. But I must say, I am getting increasingly disappointed with the build quality of the car.
