According to recent posts on Twitter, Tesla owners who have not updated their in-car software have begun receiving notices to update their vehicles or lose access to critical connected car features such as the Tesla Mobile App, streaming media content, voice commands, and more. The notice which was appeared in numerous Tesla owners’ vehicles recently cites “increased security” for the Tesla network as the reason for the mandatory update and owners have until May 1, 2020 to update to at least version 2019.40.2.3.

The message Tesla owners have received is as follows:

Tesla Over-the-Air (OTA) updates are easily one of the best features of owning a Tesla, but some owners are still resistant to updating citing fear of potential stability concerns and other issues. While this may inconvenience a few stragglers who don’t want to update, mandating software updates to the vehicles are a positive thing as one vulnerability of Tesla vehicles is that they are all connected. As a result, security issues are a real concern which must be addressed via security updates.
