Internal gage is not calculating air pressure in tires correctly? Is there a recall on this? Or do the fuses or sensors need to be replaced?

Hello, are you saying the tire pressure low indicator is coming on? Or just that the pressures fluctuate? Pressures will fluctuate constantly due to temperature mostly. In the event the tires are inflated in accordance with the pressure listed on the placard on the driver's door jam -- and the warning light is on -- consult your owners guide for the proper re-calibration process on how to reset your tire pressure indicator.
