Reading this: one idea. Change the wheels to something else (eg 20inch winter wheels), drive till the wheels are recognised and then set them back to the proper size

It might be worth following the procedure in the fourth paragraph of Madelvic's post (Teaching while driving) and seeing if that solves the problem. When the car is stationary after driving press the right hand steering wheel button (when TPM is displayed). This will show you what pressure is to be adjusted, corrected to 20 degrees Centigrade.
