Chrysler recalls Liberty and Grand Cherokee for airbags that go off without a crash due to bad capacitors.

It is not just motherboards anymore...

Hmm, not a surprise they had to be bailed out... Buying cheap for something so important imo, brings their vehicle safety rating to a 0.

You'd think that they would have finally managed to get this right by now.

Actually come to remember that Toyota had a similar problem, recall last year with new Rav 4s as the problem was something with the SRS control unit and the side curtains could accidentally deploy. The cure was a new SRS ECU.
All car companies have their problems these days.

To be fair this was 2002 - 2004 Jeeps. That WAS the bad capacitor era. A lot of good companies got burned, not because they themselves cut corners, but because sub contractors bought what they thought were quality caps from suppliers who apparently got inferior dialectic from their chemical suppliers.

And like PCs, it takes several years for these caps to start leaking and fail because it's a function of heat. PC's stay pretty warm. I'm guessing airbag electronics don't, so they took a bit longer for the dialectic compound to break down.

Are these caps made in China?
