Nothing happened as far as I can tell...I just took it in, they switched the tires, didn't even drive it...and gave it back. I was there the whole time.
It's a lease so I really don't care enough to put the effort into putting the tires back on as they originally were. Just interesting that it happened.
If it pulls, the tires will wear significantly faster, which means you'll be buying tires that much sooner for the car you don't own. Since it's a lease, the car is under warranty and the dealer did the rotation so they'll stand behind their work and the parts on the car. A significant pull when the tire is rotated in one direction but not the other (with no changes otherwise) would be alarming and indicates a rare tire manufacture quality issue (thus, under warranty, as it's not due to normal wear). It should only take the dealer about an hour to rotate the tires side to side and test drive it to determine what's going on. They could even put it on the alignment rack and check the alignment in about ten extra minutes.
Even using a lift inappropriately to lift the car for service could cause a steering alignment issue, so don't think just because the car wasn't driven that nothing is wrong with the car. As I said, purely rotating the tires side to side causing a hard pull sounds extremely questionable.
