Feb. 21, 2018—Raj Nair, one of the first promotions made by new Ford CEO Jim Hackett, left the company Wednesday afternoon, effective immediately, amid an admission of "inappropriate behavior," the Detroit Free Press reports.

“I sincerely regret that there have been instances where I have not exhibited leadership behaviors consistent with the principles that the company and I have always espoused. I continue to have the utmost faith in the people of Ford Motor Company and wish them continued success in the future," Nair said in a statement released by Ford.

Ford announced that Nair, executive vice president and president, North America, "is departing from Ford effective immediately."

The statement continued: "The decision follows a recent internal investigation into reports of inappropriate behavior. The review determined certain behavior by Nair was inconsistent with the company’s code of conduct."

The company did not elaborate about the conduct. Nair has been president of Ford North America since June 1, 2017. His replacement will be subject to an announcement in the near future.
