At the beginning of the millennium, the band faced some controversy when "Banchy", the group leader, fired Cotto and Santiago on the grounds of alleged discipline problems.

Cotto and Santiago would go on to form Grupo Stars, while Serrano replaced them with Alex Rivera and Juan Luis Guzmán.

Grupo Manía released the single "Te Vi", which only featured "Banchy" and Alfred Cotto as the only two remaining members of the group.

Later in November, the band released their 15th studio album La Marca, which included singles "Otro Loco", "Te Vi" (a different version from the original one that featured Alfred Cotto) and "Escápate".

Vélez also stated that he "doesn't know the reason yet" for his dismissal and that he always gave 200% of his effort, while also thanking Grupo Manía for giving him a chance to belong to their group and the fans for all the love shown.

Later in January 2018, Grupo Manía announced the arrival of new member, Emanuelle Vizcarrondo to complete the four-men group after the dismissal of Jhonny Vélez.

However, for unknown reasons, the album was not available in any digital platform, or at any store as a physical copy at the announced release date, despite the group's social media claim that is "available now".

The group then announced on social media that they were having a "delay" because of the album's release date being on a Black Friday, and that they are expecting it to be available "at any time".

The band will work on their next album, as Grupo Manía -being a Tropical group- are more subject to increase their fandom from live presentations and album/single releases, as opposed to online streams.

On March 30, 2024 Raúl Armando Del Valle announced on his Facebook page that he received a letter from the group's owner himself, "Banchy", indicating him that they will no longer need his professional services.

Raúl Armando announced a long story in his Facebook page stating that he doesn't understand why he was dismissed from the group because he always gave his 500% of effort.

Pray that the orders you are waiting for can be completed, said Héctor Banchy Serrano, group leader, about the possibility of reintegrating his brother, one of the original members of Grupo Mania who left in 2015 to pursue a solo career.
