I hope that when lolachampcar speaks, Tesla listens!
I'm glad they are working on this, but I'm curious... are we talking about cars not being aligned property at the factory, factory aligned cars losing alignment during transport, or a deeper issue that allows a good alignment to go bad over the course of normal driving? Have you received any hints from Tesla where the issue might be in this spectrum?
I mentioned the alignment drifting during transport to the local service manager. He has over 10 years of experience as a Mercedes Benz service manager. He told me that he had never heard of that particular issue. He said their #1 complaint at MB regarding alignment was that most, if not all cars, would drift to the right due to road crowning with a proper "factory spec" alignment. He said that due to those complaints, at Mercedes they gave their customers a choice whether they want to compensate for the road crowning in the alignment. The drawback to that, of course, is that the car will drift to the left when on a perfectly flat surface.
One interesting note from my recent alignment. I asked them to check the torque on the toe link bolts and they told me that they were torqued to specification and that they did not see anything unusual in that regard. However, toe and caster adjustments were required. My car was previously aligned by an outsourced 3rd party who didn't do a very good job. The alignment from the factory felt great, and now my car feels as good as it did when it was factory new.
