And there were some drivetrain software bugs that Toyota did acknowledge and fix (at least partially). My '07 Camry was dangerous to operate for the first few months before a firmware update. Prior to the update, it would accelerate well from 0 to about 15-20, but then almost coast for a few seconds before the speed would increase further. It felt like my 4-cylinder was suffering from severe turbo lag, and it made turning onto busy thoroughfares quite scary when the speed limit was 45 or more.

That's me schooled. I'd not been party to that (not being in the US) I'd missed it.

It sounds like a proper mess. How curious that much is revealed that the NASA people didn't speak of. Maybe because it was ostensibly an investigation at the behest of NIHIST to demonstrate that they hadn't let Toyota off the hook.

It is also somewhat disturbing that these are not Toyota parts but parts sourced from NEC.

I'm still not convinced that Toyota deliberately hid their knowledge of system failure. A software update would have been much simpler than the millions of physical modifications they chose to make, including fetching customers cars on transporters because they owners were too scared to drive them.

Yes their were bugs, but nothing implicstingt actual observed failures.
