[19] In 2019, Nissan confirmed that the Infiniti Q70, Q70L, Q30, and QX30 models will be discontinued after the 2019 model year due to poor sales as people in Canada, Mexico, and the United States prefer to purchase crossovers and SUVs instead of sedans, hatchbacks, estates, convertibles, and coupes.

Another reason for the discontinuation is also caused by Nissan's plans to withdraw the Infiniti brand from the Australian, New Zealand, South Korean, Hong Kong, Macau, Vietnamese, Indonesian, Malaysian, Singaporean, and West European markets by the end of 2020, with Nissan already withdrawing the Infiniti brand from the South African market in 2017 due to losses and poor sales.
