Two Long Island auto workers were caught on a secret dash­cam sexually degrading a female employee — who discovered the video on YouTube and filed a harassment suit against the company, The Post has learned.

Westbury Jeep workers Anthony Hardt and Matthew Messina were busted when the customer who was having the vehicle fixed saw the video and put it online.

Melissa Kendall, 33, was stunned when she found it and heard Messina bragging in crude terms about how he planned to have sex with her.

After Kendall complained to her bosses, she was fired, she claims.

She filed her complaint against Westbury Jeep, VIP Auto Group, on Tuesday in the New York State Division of Human Rights.

Her lawyer, Lenard Leeds, and Westbury Jeep declined to comment.
