Tesla tried multiple times to fix my FWD alignment but kept saying it was within spec and that it could never be perfect and the best they could do is split the difference between adjacent panels. The last adjustment they made to anything was the right front door which was undeflush with the FWD at the top of the panel. They adjusted the door strike to bring it out so it was flush with the middle/top of the FWD but overflush with the bottom.
I was able to achieve perfect panel gaps and alignment once I realized the root of nearly all the errors starts at the front fenders. Once I realigned those, everything else fell into place including the front doors and finally the FWDs......just in time to surrender as part of the buyback settlement. It had lots of other ongoing issues with the vehicle itself, so combine that with the fact that I got my purchase price and not the new $50K lower price, I was happy to be rid of it.
Still, in all, I spent about 40 hours on panel re-alignment most of which was FWD strut and hinge disassembly. Even bought a shop hoist like the one on the FSM to support the door with the struts removed.
