I'm guessing my car being a P90DL demo did it no favors in regards to the people taken for Ludicrous launches and the...generous-ness of their bodies. Regardless, at highway speeds the last few months, I'd notice a deep interior rattle, and over the right bump a squeak. Took it to Palm Springs SC to have moonroof shudder checked, and driver door alignment (wasn't right at delivery) resolved..and a tech rode with me on a bumpy road. He rode in the back, and something made him just grab the passenger seat and give it a SHAKE. Surely enough, it wobbled. My seat had a similar, but tighter movement. So the appointment to resolve the other issues came and went...but I was told I'd have a wait a month or so for the seats to be resolved because...they're making me new seats. Apparently, Tesla doesn't keep seat PARTS in Fremont, and right now doesn't even keep SEATS on hand in large quantities. But the point is, I'm getting brand new seats. My husband of course, giddily asked if we could have the new ventilated ones but..yeah...no. But yes, I'm actually pleased about this.
