If you read the article it clearly states that these plans have always been there but it is the right time to talk about it so that Trump stops annoying them in public. All the Mexican jobs will still be there. Ford will not build a new factory there but will upgarde their Mexican factory. The jobs they are creating in Michigan where always the hightech EV  (R&D) jobs. All the big 3 have nicely recalabirated their message to get Trump of their backs. Just give Trump what he wants to hear and he goes away.
