We really have to quit with this mild speculation BS. Being overly consumed with turning every stone is insane when the plain and simple truth is that the Marxist administration wants Toyota trashed because it’s non union. End of story.
The cure for Toyota is to knuckle down to Bozo the -resident HMFIC and get “unionized” ... the problem goes away!
Two squirts of WD-40 in the accelerator channel during normal maintenance solves the run away problem.
