This morning, I noticed the TPMS warning. I checked the tires and the front right one was at about 24psi. Filled it up to 33psi and the warning went away.
I was wondering if it would work at all because I had changed to winter tires and wheels. The winter wheelset had sensors installed with them (from the TireRack using OEM Hyundai sensors.) According to the TireRack, the sensors needed to be calibrated to the car. When I installed them, however, I got no error message. That made me wonder if they would even work. Today I found out.
Funny thing is the Hyundai service rep also told me there was a TPMS calibration procedure and agreed to do it for free twice a season for me (I negotiated this as part of the purchase.) When I got no warning or error message I didn't bother taking the car in to the dealer for the calibration.
I wonder if this is something that was never required on the Genesis (but required on other Hyundai's with TPMS) or a running software change. Our previous Volvo required no calibration. I was told calibration was only necessary for cars that alerted the driver to which wheel was low....the Volvo doesn't do that. I didn't investigate further, to see if there was an alert to a particular wheel on the Genesis but the main light certainly didn't provide that information.
On a side note I'll have to keep an eye on that tire and wheel. It was really hard to get the tire gauge to read that stem...like the push pin was too low. Perhaps they damaged it on installation. I recall reading that can be an issue and one should take extra care when changing tires with TPMS sensors.

"One item that’s absolutely necessary to have when replacing TPMS tire pressure sensors that have a valve stem with a nut at the base is an accurately calibrated inch-pound wrench (mechanical or electronic). The amount of torque used to tighten the base nut on a TPMS valve stem is critical. If you don’t get the nut tight enough, the seal may leak and the tire will lose air. If you overtighten the nut, you risk damaging the seal or valve stem, which would also cause an air leak."
