I think its a good thing anytime a car company owns up to an error and does a recall...
That said, in my experience, Toyota is TERRIBLE at owning up to their mistakes. I've had quite a few problems with my Toyotas that have been widespread, and Toyota never recalled them or even would cover repair costs. Some of them have even led to class action lawsuits to try to force Toyota into coverage. That is not the sign of a company doing the right thing....
I find it interesting that we praise Toyota for this and curse GM or Ford when they do the same. Shouldn't ALL efforts to correct problems be seen in a positive light and all denials of problems be seen as a negative?
I've had the opposite experience. They have never failed to acknowledge warranty work, and it has happened more that a half-dozen times in three years.
