Gilbert Passin, Tesla’s vice president of manufacturing, has left the company, according to a source familiar with the matter.

He joins a long list of high-level employees from all parts of the automaker who’ve made their exit.

Tesla is continuing to struggle with the ramp-up in production of its new Model 3 car.

Gilbert Passin, Tesla’s vice president of manufacturing, has left the company, according to a source familiar with the situation.

Emails sent to his Tesla account bounced, and neither Tesla nor Passin responded to Business Insider’s request for comment.

According to Passin’s LinkedIn page, which says he is still at the company, he spent almost nine years at Tesla. It says that from 2010 to 2013, he helped to launch the manufacturing of the Model S. Since then, he helped launch Tesla’s manufacturing efforts around the world and run its Supercharger operations, and he was involved in Tesla projects for Daimler and Toyota’s RAV4.

Over the past year, several senior employees from all parts of Tesla have left the company, including Gabrielle Toledano, its head of human resources, Sarah O’Brien, its vice president of communication, and Liam O’Connor, it’s vice president of supply-chain management, to name a few.

“The mass exodus of people has reached unbelievable levels,” one former Tesla engineer, who asked to remain anonymous, told Business Insider.

Tesla started the year with what CEO Elon Musk called “production hell” as it attempted to ramp up manufacturing of its new Model 3 car. That was followed by what Musk called “delivery logistics hell” as the company struggled to deliver the cars.

But the struggle is not over. In the next six months, Tesla needs to find $1 billion in cash to meet debt obligations.
