The pair joined forces at the beginning of the 2021 season and hit it off when they claimed second on their Vodafone Rally de Portugal debut in May.
Crashes in Sardinia and Kenya proved frustrating for Sordo and, in a statement released on Friday, the i20 star explained that fellow countryman Cándido Carrera would replace Rozada in the right-hand seat.
Carrera brings a wealth of experience, having started well over 250 events, including more than 30 FIA World Rally Championship outings.
Many of his recent outings have been alongside Spanish pilot Daniel Alonso in Rally2 machinery, although it is understood he accompanied Sordo in a World Rally Car at a pre-event test before Rallye Monte-Carlo in January.
"I am grateful to Borja for his dedication and professionalism," said Sordo. "He has shown me to be a great co-driver inside and outside the car.
“Unfortunately, despite the enormous work that the two of us have done to understand each other one-hundred per cent, the understandings of my notes on the stages have not been perfect.
“I hope to connect with Cándido Carrera as soon as possible and be able to celebrate great successes together this year,” he added.
It’s not yet clear at which rally the new duo will debut, with Irishman and former winner Craig Breen driving the team’s third car at Renties Ypres Rally Belgium next month.
