went to dealer yesterday, front pressure need to be 35 and back 38. he reset my sensors, and now its fine, the dealer did not add any air. I guess its easy to do, just go to the tire pressure screen, down arrow, hit ok and you are reset. drove yesterday and today, no issues!

On North American models you have to check the fuel filler door for the full list of recommended pressures. The info on the door pillar is incomplete and the manuals are no help.
Note: The door pillar shows maximum load rating and the recommended tire pressure needed for that. If normal duty pressure is 32 all around (no front/rear difference) and max load pressure is 35PSI front and 38PSI rear (3 PSI front/rear difference), then the warning appears if you run a larger front/rear pressure differential. That's what happened here. Drivers should run normal pressures unless carrying max load all the time. Unfortunately, many dealer staffers aren't aware that the full tire pressure guidance is located on the the fuel filler door. They look on the pillar and think it's the proper pressure for everyone, but it's not.
