There is a Forum Member that replaced the original OEM wheel sensors with the Shrader 33500 wheel sensors. He claims that the TPMS warning light comes on when he starts the car but goes out after he drives a few miles. Haven't figured out why a "re-learn" occurs but it's only temporary. Could this be a tire with air pressure right on the borderline & after the tire heats up, & the tire pressure increases, the warning light goes out. Not convinced this Forum Member has that condition based on his experience & knowledge of this car.
