For his performances in the 2019 IPL season, he was named in the Cricinfo IPL XI
In April 2019, he was named in India's squad for the 2019 Cricket World Cup. On 27 June 2019, in the match against the West Indies, Pandya played in his 50th ODI.
In January 2019, Pandya appeared with teammate K. L. Rahul on the show Koffee with Karan, and made several controversial comments which were met with immediate public backlash. During the interview, Pandya spoke about how he had proudly informed his parents of his first sexual encounter, which was well received by them. He also proclaimed that he likes to "observe how women move" at high-end bars and nightclubs, as well as on social media and then went on to liken himself to a black person saying, "I'm a little from the black side so I need to see how they move". The public categorized his monologue as indecent, derogatory, misogynistic and disgraceful. Pandya apologized for his remarks by saying that he had gotten carried away by the nature of the show.
The Board of Control for Cricket in India (BCCI) responded to the controversy by saying, "It will be considered whether players should even be allowed to appear on such shows which have got nothing to do with cricket." The BCCI found the comments as very crass, sexist and cringeworthy, and was not impressed by the apology, seeking appropriate legal action into the matter as it was a breach of conduct. Both Pandya and Rahul were handed a suspension until a pending investigation and were called back from the ongoing tours of Australia and New Zealand. Furthermore, on 13 January 2019, Gillette suspended their brand association with Pandya for its Mach3 razor. On 24 January 2019, after lifting the suspension on Pandya and Rahul, the BCCI announced that Pandya would re-join the squad for the matches in New Zealand.
