Has anyone had the same problem of loosing air in their tires??? The tire monitor screams at you when any of the tires loose air. I CANNOT find any gas station within 30 miles that can handle the valve stem for air. I HAD TO GO TO THE DEALER TO GET AIR IN TIRES!!!!!!!!! Is there an adapter that can be purchased some where or do I just have to go to the dealer? So far no problem with air loss (at least 6 months).
