2012 Elantra GLS. Wife comes home and says the TPMS (tire pressure monitoring system) light on the dash is lit. I check the tire pressure. None abnormally low but I decide to top them off. Notice that two of the valve stem caps are broken. The tips are broken off so I can see the little red gasket. On opposite sides of the car. No damage to the wheel covers. The valve stems don't stick out past the wheel covers so I wonder how the caps could have gotten broken.
Could that be why the TPS system is giving me a warning? If by chance there was a pressure issue does the light reset itself or does the dealer have to do it?
