Turns out, nothing horrendous. Only air suspension folks would care about this thread. After jacking up a front corner to change the wheel seasons over... I noticed the whole car was sitting at a "very high" type of setting. Thinking that's odd, I always have Normal height selected for garage parking. As I was jacking, I guess the car must have fought its way up on all other corners trying to keep level ... but even the wheel I was working on was now also in "very high" position (but dangling in the air). Then it hit me DOH! I guess noises in the garage prevented me from hearing the Tesla doing its air injection... otherwise I might have clued in faster to get Jack Mode turned on. The remaining 3 corners enjoyed Jack Mode.
