Would you give an unlocked laptop to tech support to use without you present?

So why give your unlocked MCU to a Tesla service tech? We’re driving a big cell phone on wheels and it stores codes for gates, garages, WiFi passwords, and a bunch of other personal details from locations, contacts, received, and placed calls - etc.

How comfortable do you feel when they put it service mode with a simple 4 digit code and call it good till you get the car back?

  • Until some day when the Tesla engineers design a way to store your 'personal' data separately and encrypted from the rest of the MCU Operating System, what do you suggest?
  • If you’re concerned about it, you can always do a Factory Reset before having your car serviced, which will erase all your personal data. Of course, you’ll have to set everything up again after getting your car back.

    Note that some of the data, including phone calls, contacts, and calendar entries, can only be accessed when your phone is connected. It’s unlikely WiFi passwords are stored in a format that a service tech could access. HomeLink codes would only be useful to someone driving your car.

    Factory reset isn’t a secure delete. Most of the data is still accessible until the sectors are overwritten.

  • @6EQUJ5 - Okay, but your original post was about service techs accessing your personal data. Do you really think anyone in service cares enough about your data to remove the storage device and try to recover deleted files?

    Factory Reset is more than adequate.
  • People are worried about their data privacy yet they use cellphones, google and social media regularly.

    Anything on the internet can be hacked and accessed.
    But nowadays it’s impossible to buy a plane ticket without entering all personal info online.
    You just have to pray that when your info gets hacked it won’t be too problematic to get it removed from your credit score.
    When we were students, my wife got hey credit card fraud online and hey bought $3100 of oil in the UK, she had closed that credit card the same mount it happened, they closed the card and sent the outstanding bill to the address 412 when we were living on 410. We found out about that 3 years after. Never had any call about this. It took 3 years to get the credit score reversed and to show it was stolen credit card fraud.
  • I don't have any information in my car that's more sensitive than the credit card already on file with Tesla.
