Tl* the contact owns a 2010 kia forte. The contact stated that the low pressure tire warning light illuminated. The contact added air to tires and the problem was resolved. The failure recurred and the side passenger rear tire was constantly loosing air. The vehicle was taken to dealer however the contact did not receive a diagnostic. The contact stated while driving 60 MPH, the passenger rear tire exploded. The tire was replaced but the failure recurred with the new tire.

The tire deflate rapidly when driving at 70MPH on freeway. When in the tire shop technician reveled there was no puncture but the stem was missing. After removing the tire the stem was found inside the tire with visible corrosion signs. By inspecting the rest of the stem, was found that all three stem supporting nuts have traces of corrosion but one of them on the passenger front wheel the nut was cracked. We concluded as cause of the problem was the crack in the nut that secure the stem in position.
