Left rear TPMS valve stem corroded and failed while driving on highway. Tire quickly deflated. Tire dealer replaced tire, but valve stem was too corroded, so a regular valve stem was used. Two days later, the right front valve stem failed, again while driving on highway. While at tire dealer, I had them replace the other two TPMS sensors that hadn't failed (yet).

Low tire pressure came on. Check tire for air pressure and the valve stem broke and flew off 20 feet. Thank goodness I was not driving as this would of caused a crash indeed especially as I was going to be traveling on the expressway at 75 mph. Something needs to be done about this problem before someone gets maimed or killed.
