Infiniti Q70

Recalls
The 2014 Q70 hybrid vehicles manufactured November 7, 2013, to December 10, 2013 were recalled due to damaged housings could crack and fracture, creating road debris and disabling the vehicle and increasing the risk of a crash. In addition, 2014 Q70 hybrid vehicles manufactured November 7, 2013, to May 7, 2014 were recalled due to a software error, the electric motor may stop working while the vehicle is being driven using the electric motor only, leading to increase the risk of a crash.

The 2014–15 Infiniti Q70 was recalled due to fuel pressure sensors not being sufficiently tightened during production, leading to possible fuel leak.

Discontinuation
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. Nissan has no plans of abandoning sedans entirely and plans on possibly introducing an Infiniti EV vehicle in 2021 for the 2022 model year based from QS Inspiration concept.

The Q70L continues to be offered in the Chinese market as of 2022.
