Unfortunately, sexual harassment in auto dealerships is nothing new.
It seems the male-dominated industry has generally not evolved with the rest of the U.S. workplace in training and preventing sexual harassment. In California and other states, harassment of third parties (customers and vendors) is also prohibited.
A non-harassment policy, training and awareness are critical components to reduce the likelihood of harassment complaints, but ownership must take personal accountability in ensuring all managers and employees are following the rules.
What you allow, you encourage.
