C450 opener randomly will stop one foot short of completely open or one foot short of completely closed. This is dangerous because if you are not completely paying attention, our SUV could rip the garage door off. Another time I entered the house without waiting for the garage door to completely shut, and it stopped a foot above the floor. It stayed that way all night, let the heat out, and potentially could have let someone crawl under and enter the house. This is a huge liability issue that I hope Chamberlain will address.
