Since 2012
In 2012, the call letters were changed to KFXV-LD to better reflect the station's status as a translator of a Fox station. Furthermore, the station began to identify itself by the KFXV calls and channel despite the fact it was still branding itself as channel 2. It was also announced that The CW would henceforth be referred to as KCWT, also a low-power station owned by Entravision, located on analog channel 30. The analog feed of The CW was moved to KCWT, and The CW now airs on that station (using virtual channel 21).
Around that time, it was announced that a new Spanish-language network by Fox called MundoFox would be coming to the Rio Grande Valley when it launched in August 2012; reports indicated that a full-power station owned by Entravision would assume the affiliation. While KFXV remained the Fox affiliate, XHRIO broke off and began airing MundoFox programming on August 7, nearly a whole week before MundoFox's scheduled full launch date, XHRIO began airing MundoFox on 2.1 calling it a "test signal". The next day, via Fox Rio 2's Twitter feed, it was officially announced that MundoFox would be coming to XHRIO 2.1 and Fox would remain on KFXV 67.1. Although this switch had already happened unofficially, it officially took place on August 13, 2012, effectively splitting XHRIO and KFXV into two separate and distinct channels, making KFXV 67.1 the official Fox affiliate for the Rio Grande Valley. This also marks the first time in the network's history that the valley's Fox station is of American origin, with an American callsign.
Despite moving the Fox affiliation from channel 2 to 67, the station was not rebranded from its "Fox 2" moniker, making KFXV's primary branding match its location on satellite systems rather than its virtual channel. This was changed in 2016, when the station began branding with its call letters.
On May 27, 2020, KFXV-LD became KMBH-LD. This came after KMBH was bought by Entravision and became a full-power Fox affiliate as KFXV.
On October 1, 2021, MyNetworkTV (which was carried on KFXV and KMBH as a secondary affiliation) moved to Antenna TV O&O KGBT-TV (channel 4) also as a secondary affiliation.
