Ever since day one and through numerous software upgrades, I can't get my TPMS to work properly. After tire pressure adjustments, if I press "Store Tire Pressure" I get a message that tire pressure storage is in progress... The screen would show the spinning wheel cursor. It doesn't matter how long I wait (one time I was in a parking lot waiting for 25 minutes), the spinning cursor continues. Volvo has to have the most primitive TPMS system.
