I picked my G550 up last week with the same issue. TPMS was reading 30-31 psi on all 4 tires. According to the gas cap label, they should be at 32-35 for front and 40-45 in the back so I added air and all warnings stopped.
When you reset it, it no longer establishes a new baseline so you must add air to correct it.
