1. What does that have to do with identifying the issue before sale to the masses? The vehicle was tested here on regular pump gas, and ethanol free solves it for SOME, not all.
2. Fair, no argument there. BUT, they did issue a TSB which indicates that something requires fixing.
3. Agreed, however IF they were aware of the noise and deemed it "normal" a TSB should never have been issued, no "new" pump designs should have been put out. But those things happened, the "solution" was put into place either due to consumer demand or they were unaware of it in testing for whatever reasons, in which case you'd be asking the same question we're asking here: "Why wasn't this caught earlier?"

Windows and tail lights are small assembly glitches remedied by a manufacturing process adjustment. Neither the windows nor the tail lights have rendered the car inoperable.

You're right they're smaller scale and impact BUT they are issues which have required rework from Toyota/Subaru to remedy, it is reasonable to ask why these problems weren't known sooner. There is little reason why a test mule would have different manufacturing processes or different parts from what was sold to the rest of us (especially things as mundane as taillights, fuel pumps and windows, those should all be basically off the shelf). The question "Why has this happened to us and why wasn't it caught in testing" is valid for all the things I posted.
I admit they are not comparable to the injector seal issue but they are widespread and would have been caught on 10 randomly selected and thoroughly tested cars, at least from the pool we all bought ours from.
