Sonata I45 (YF - 2011+) :: False TPMS Warning Light Flashes Then Turns Solid

The light flashes then turns solid. I checked the pressure to find 32lbs in the tires. I pumped them back up to 36 front, 35 rear (per suggestions here to minimize steering wander).

The light remains on. Knowing the pressures were fine, I have driven it several days to see if the light goes out on its own. No dice.

While driving last week, the wife asked about this and we pressed the Blue Link connect button. The service rep who responded said she saw no pressure warning on her remote panel.

Over the weekend, I tried inflating the tires to 40psi, thinking that the higher pressure would reset the light and then I could lower the pressure to normal levels. That did not work, either.

So yesterday, I called the dealer and the service rep said the system warns of BOTH under pressure and over pressure. She suggested setting the tires to the "sweet spot," at 35psi. I did this, and the light remains on.

I guess I will need drive to the dealer and let them piddle with it. I like the system, or at least the idea. But I hope I don't have to drive to the dealer after every attempt to maintain the tires.
