Here is a story that says that Tesla changed the battery settings over the air. The article emphasizes that this change was motivated by an abundance of caution.

Tesla claims that batteries are safer than gas; however the very fact that Tesla changed the battery configuration over the air shows that the battery configuration can be changed remotely.

Unfortunately, the problem isn't just restricted to EVs. Most new cars have complex software which can be updated. Is a battery controlled by hacked software anymore dangerous than a fuel injector controlled by hacked software?
