Wow, you are absolutely unbelievable. I can't tell if you're a GM employee or just a fanboy. You repeatedly downplayed many posters comments about a potentially lethal issue with these trucks. For the average consumer in a high traffic situation it isn't going to make a difference if the brakes have failed at the 100% point or the 10% point. The only thing you are accomplishing is alienating good folks who have experienced a BRAKE FAILURE. My wife almost crashed into an intersection last week full of 60 mph traffic. If several of the vehicles hadn't swerved when the truck entered the intersection she may not have survived it. Would your answer be, but you still had 10% left?
