This how people are gonna find out how bad of an idea to allow the manufacturer to have that much control over your car after purchase. Tesla will shut their cars off if they find them jail breaked.

Just like the guy that wasn't allowed to fix the cooling hose on the battery Tesla's only option was to replace it. A third party fixed it but he still had concerns that they would shut it off (citing safety) because he wouldn't buy a whole new battery after he fixed it. Also barring him from quick charge stations was another concern.

Tesla shutting off jailbreaked cars would be illegal in Europe at least

  • jailbreak
  • disable all traffic from certain apps
  • add all tesla domains as 0.0.0.0 on /etc/hosts, just to be sure
  • ride off into the sunset

Couldn't they add a hardware chip that acts like a tamper seal?

That's the thing that gets jailbroken.

Depending on how it's implemented, beating it will be a matter of shorting some circuits. See how PS1 and 2 were jailbroken with modchips.
