Ford's North America president Raj Nair is leaving the company, effective immediately, the automaker announced.

The decision follows a recent internal investigation into reports of inappropriate behavior, Ford said.

The review determined certain behavior by Nair was inconsistent with the company’s code of conduct.

“We made this decision after a thorough review and careful consideration,” said Ford President and CEO Jim Hackett. “Ford is deeply committed to providing and nurturing a safe and respectful culture and we expect our leaders to fully uphold these values.”

Said Nair: “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 has been president of Ford North America since June 1, 2017. Prior to that, he served as Ford’s head of global product development and chief technical officer.

Nair’s replacement will be subject to an announcement in the near future.
