The factory latches whether for push button or turn down are among the most dangerous and biggest POS ever installed on a vehicle. For $350 you can keep from killing your kid by installing an Altman Trique Latch kit that is the first thing that should ever be done on an AD.
I have to agree with you on POS design of our latches. The thing that kills me is that they are not a simple design. Some idiot train pilot had to put a lot of hours into this design. And they all fail over time.
