While it may not be possible to forget, I also think it is rather petty and vindictive to keep judging something on ancient history. As time passes, events and issues of the past become less and less relevant to the product offered today or and one should make decisions based on the way things are, not on how they used to be.
If I had a car with peeling paint, I would allow the manufacturer to correct the issue, and if it was still an issue I would need to wait for the manufacturer to provide a track record showing the issues have been resolved. For me, it's why I would not buy an Audi today, but if they show a few more years of having their act together, I will relegate the reliability issues to the past.
