Tire Pressure Monitors

I've delivered 4 G550's so far and all of them seem to have TPS problems wondering if anyone else has had this issue.

After I had my tires swapped out, one of my sensors needed a day before it finally registered. I was actually on the way back to the tire installer when it started to work.

Not sure if this helps, but my G550 was manufactured the third week of September.

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.
