Official summary
Some 2022-2023 Maverick vehicles equipped with 2.5L full hybrid electric vehicle (FHEV) powertrain may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P2C22, P237C and/or P237D stored in the powertrain control module (PCM). This may be due to water intrusion in the exhaust heat exchanger.

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.
