Official summary
The Tire Pressure Monitoring System (TPMS) ECU has a built-in antenna that receives signals from the TPMS sensors. Earlier versions of the TPMS ECU were equipped with an antenna that might not receive reliable readings from the front sensors, causing the TPMS indicator light to be displayed inaccurately, even when the tires are properly inflated.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
