I'm shocked that everyone here is so against GM on this.
Given the complexity of a car and all the things that could go wrong, this is a very minor issue. The brakes still work (no ABS though), steering still works (it's just harder to turn), and lights still work. It basically turns into a car that's 20 years older, not a coffin on wheels.
The driver also knew there was a problem, wasn't happy with it, but still drove her car regardless and then wasn't able to cope when it happened again. She wasn't forced to drive it.
Maybe it's because I tend to drive older cars, but I'm all too aware that they're machines and they break. I've had all kinds of things fail when driving and I've had to try and cope with them safely. Luckily I have, but if I hadn't been so lucky I wouldn't blame the car manufacturer.
100 years ago you could get killed by all kinds of things and it was more or less just accepted - why are we now at the stage where a switch that's a bit too easy to turn is the cause of all this blame?
