No, not all of them, only the ones that have the problem. .
Not really, if the problem is widespread anbd can not be traced to a specific Item, MFG Date, Serial,... they are FORCED TO RECALL ALL OF THEM to Certify the Problem was Fixed.
Been there done that.
Sure. Please cite the event. What auto recall could NOT be traced to a specific item, MFG date, serial etc. where they were EVER forced to recall every car manufactured by a auto manufacturer. You claim you were there and did that. So tell us. What car, what manufacturer. . .
The only one i can think of was the deliberate fraud from VW on their smog certification testing, and that doesn't meet the requirement. Even there it was specific models and years and serial numbers, not all of their cars.
