TPMS Problem: 2018 Sport Hatch
Well, while not the same problem, I had my light come, not flashing but on continuously, and noted all three of the tires took air, the other none. Recalibrated over a 75mi trip and light comes on again. All four tires took air...another 75mi and no light. Go to dealership and they have no answer but recalibrated "whole system". Of note, I told them I had put 35 front, 33psi back as per manual..their response: "Perhaps the uneven pressures caused light to come on." Oh well, that's a dealership for you.
