Every car I come across with a similar direct ignition system seems to get about the same miles (70K or so) out of these units. Saab, Audi, I think BMW also suffers from it. Even two Nissan's I've owned, an '88 and a '99 suffered from the same issue. I'm not saying that you could not build electronics to survive in this environment, but heat is the #1 enemy of electronic components. Dissipating that heat is very difficult in on top of an engine and under a hood. I think the current round of recalls is due to what you stated: Some sort of shortcut they took made those DI's fail very early. But, as I said, I think 70K is sort of par for the courser
