The faulty accelerator pedal might not be fixable!
If you were a Toyota dealer, I imagine at this point if you had a customer, you'd say something like, "I can't sell you a car today, but if you put a deposit down, I'll guarantee you the model of your choice in, say, 2 weeks, when we have this problem resolved. And I'll add $1,500 to the incentive package." I suspect that Toyota will have to initiate some kind of program like this; they will, in effect, be lowering the price of their vehicles. Which will not be good for profits.
