Really no way to tell for sure what percentage had problems. I always take what I hear on the internet with a big grain of salt as the comments are always heavily biased to those with problems. Seems like most people that have problems jump on the internet and rant about it, while people with no problems sit back and don't say anything. Then for every one person who actually had a problem and post it there are 10 other people that get on another site and will post that certain trucks has problems (because they heard about it someplace else even though they personally have never had a problem). Also don't forget about the people that rant about the truck having issues but leave out the part where they put a +200 hp tuner on it, never performed maintenance, or beat the crap out of it.
