I have no clue but im sure some components are made in the USA. Foxconn will be making chips in the US and i would make sense some of that will be for apple. China black / grey market carries everything.  no matter what it is or who makes it... They are thieves plain and simple....  Would i love American companies to make products in america... YES 100%  Sadly over the years the american market has be hostile to business, Only after trumps election have we rolled back some regulations.  Im hoping it continues... If we fall back less and less will be made here.  

We have a 2018 and a 2019 GMC Terrain and both have the shutoff feature. There’s no way to turn it off bu5 once you get used to it it’s really not intrusive. I am doubious of how much fuel it actually saves though. Maybe if you are stopped at lights or in traffic a lot but that not part of my driving... -Jim

And which of those components are actually made in the U.S? Not talking about company affiliations and locations, i'm talking about location the physical hardware is made. The funny thing is that you can build an iphone from scratch buying all the components from street vendors in China because Apple can't control the gray or black market in China.  

Sorry, I can't help with a method to permanently override it, but when I had a rental GM with that feature I learned moving the steering wheel slightly would prevent it from shutting off also.

Many thanks to SW9racer. I now have what I need. The boy will be pleased.
