Hood hinge failure is quite uncommon. You'll probably come across this problem only if you've been involved in a frontal collision. If that's the case, then you shouldn't be running around with damaged hinges on your car's hood. Unknown to many drivers, the hood's hinges serve one other purpose besides holding the hood-safety. In case the hood latch should fail, the hinges are there to keep the hood attached to your car. Otherwise, if you were traveling at high speeds and the latch fails, the hood could break from the damaged hinges and cause disaster and injury.
