They should have performed a full alignment on the car after the drive unit replacement. They should have also properly centered your steering wheel - they have a bubble level that can be mounted to the wheel that is specifically designed for that purpose. They used it on my car. They also have a new alignment machine as of about 2-3 weeks ago when I had my annual done.
Do you have the alcantara headliner? Because if you do, that cross-member is now covered in alcantara on new shipments. You can buy that from the service center and have them install it. You might like the new look and take care of the rattle at the same time!
Thanks Ampd; they did perform an alignment after drive unit swap. At first I didn't notice any wandering, then I thought it was the wind or truck ruts, and now being kind of the obsessive type I notice it all the time. So maybe something has "settled in," or else it might have been inexperience with the new tooling. In any case, I've got it scheduled for re-do in a couple weeks. Driving almost 1K mi per week lately, so it will be nice.
Will also have the rattle fixed, though I still might address it myself before then since now there's a second rattle behind the instrument cluster, or whatever it's called. OCD + 1K miles = I can hear every tap ;-) I'm thinking foam tape. No, I won't touch the instrument cluster.
Let me be clear, since I was contacted offline about it: My first post might make it sound as though teh SC was avoiding dealing with the problem. This is not the case at all. I had asked them to take care of it at my wheel rotation, and I think they ended up fixing another rattle in one of the pillars. I asked a second time but they didn't have time to do it after swapping the drive unit, which is reasonable considering it's a drive unit after all. In fact Tesla service has never been anything but accommodative, and even proactive in taking care of my car. They even valet'ed it to me half way across town the last time, which was super convenient since it was turning into rush hour and I had to get going. Tesla service is second to none IMO, in fact I'd say they are in their own class in the industry, just like the car.
The car, I bought with the attitude of "early adopter," and am frankly pleased that there haven't been more problems. It's only 3 years in production, how did they pull that off? With the occasional loose trim piece or noisy bearing it's not 100%, but it's still an amazing vehicle and they've made my experience as pain-free as possible while they work out how to produce the asymptotically perfect car.
Speaking of which, I think I will ask about the alcantara lined trim piece, it would give a more integrated and solid look to that plastic sucker up there.
