Former Tesla engineer Christina Balan, who was fired in 2014, said in an interview that her entire team was threatened with deportation for taking her side when she brought up a brake safety issue directly to Elon Musk. She's now succeeded in throwing out Tesla's arbitration case against her, and hopes to meet Tesla directly in open court in a case that could influence corporate policy nationwide. Christina Balan is a Romanian-born engineer who formerly worked for Tesla on the Model S. Her contributions were significant enough that her initials appeared on the Model S' battery pack. But in 2014, she brought up what she considered a safety issue directly with Elon Musk. She thought that the Model S' floor mats could cause a brake safety issue, similar to a situation that Toyota had recently gone through (though that also led to a media firestorm that blew the issue out of proportion).
