I do not think the ship is sinking. I believe what is happening to Toyota are the growing pains of the move to electronic components that don’t have all the bugs worked out. The throttle went from being manual to electronic and it has issues. The brakes are controlled by the computer in the Prius. Other manufacturers like Range Rover, Mercedes and others have problems as well with all the new electronics. I live in LA and see nice, new cars on tow trucks all the time because of electronic issues, not mechanical. Toyota just happens to be the goat today.
A few years ago, it was Ford with Brigestone/Firestone tire problems. All car manufacturers have a recall or problem. When the Fiat’s and Lancia’s come stateside again, you will see the cycle even more.
