But that wasn't the point of the previous poster. We're not talking about an existing issue if the car performs according to the spec you bought with it. Then that's a performance upgrade.
The question is basically whether it's an issue or something that works as intended but could be better.
A pure software update fixing an existing issue I would say no. Car companies have recalls all of the time paid for by the company when something doesn't work as expected.
A software recall should be treated the same as a hardware recall.
