Better now. They redeemed themselves. I got the call that the car was ready today (the lady who I talked to when my service adviser had left for the day was incorrect about the timeline/taking til Friday). The TPSM light is off. (I will let 8 lbs of air out of the respective tire tomorrow and then put it back in to make sure the light goes on and off). I have to say that what others have said about the Xfi vs. general mechanics at the 5*s is true. On day 1, they couldn't diagnose the problem. On day 2, the Xfi mechanic ID'ed the problem, which tells me he wasn't involved on day 1. I asked that it be the Xfi mechanic to install the replacement sensor and they said it was going to be him anyway. And voila, it was done. So I guess the moral is book the appointment on a day you're certain the Xfi mechanic will be there. So this dealer is still on the list all things considered.
