The brands really can't care about reliability if they know they'll be bust.
If the biggest item on assets and liabilities is warantees, there are a lot of tricks to reset that to zero.
And even if you win in the market, you probably had to race to the bottom for reliability.
Unfortunately, the cost of judging information to decide on reliability is too high as a consumer. So we fall back to price (which we can mostly quantify) and it is rational to choose lemons.
