Nissan needed a bailout and Renault swooped in and took over and they always grumbled about it.

They had a hand in part of the downfall of former CEO Carlos Gnosh who while not innocent either crossed the line in how company funds were handled for his homes he maintained for travel between France and Japan.

I would not be surprised if they mutually dissolved the partnership.

Their reputation has a lot of coming back to do from being "the #1 car brand for criminals."
