Are Toyota drivers still experiencing unintended acceleration?

As a former web programmer, I always thought that the Toyota unintended acceleration problem sounded suspiciously like a software bug. Programmers will write a piece of code, and if it proves more generally useful, will copy the code into other programs as needed.

The reason I suspected a software bug was because the acceleration problem appeared in different models of Toyotas with different designs. The same faulty code was being copied to different models. Furthermore, the fact that the cars accelerated out of control seemed to suggest an infinite loop. Of course, it had to be a loop that was encountered only in certain very rare conditions. Bugs like this are extremely difficult to find.

However, as far as I know, Toyota never admitted to a software problem. They always blamed something mechanical, and all the solutions were mechanical in nature.

So, did the issue get resolved to everyone’s satisfaction, or at least to the NTSB’s satisfaction? Are there still occasional reports of unintended acceleration? Does anybody know? I’ve not heard anything on this lately.
