Well, unfortunately for Toyota, the question isn't what could they have done differently post recall, it's what are they going to have to do in order to make sure they are actually correcting the problem?
According to the National Highway Traffic Safety Administration, there have been over 60 claims of unresolved sudden acceleration problems since mid-February. This is possibly more bad news for Toyota.
What does this mean for Toyota? It seems to me that the acceleration problem is not exactly what they thought it was. I think it may have something to do with the software in those vehicles. And software problems are not easy to fix. Thousands of lines of programming code, and the problem could be hard to find. I say that it could be a software problem because if it were only a physical piece that needed to be fixed (which is what they said the problem was and is what they replaced) then there couldn't be any unresolved problems because the problem wouldn't physically exist anymore.
I don't claim to have any answer as to why there are problems or what those problems even are. All I am is saying is that I think the recall story for Toyota isn't quite finished yet.
