Product review (5 stars): Mine seems fine, but I guess I've never had a dishwasher ...
It's NOT the latch! I will admit that I thought I had problems with the latch too, but as I got to looking at the dishwasher itself, I discovered it isn't the latch at all. The problem that I would imagine every person on here who says they had a problem with the latch is that they don't have the top rack pushed back all of the way. It seems the way the dishwasher is built, that top rack mechanism fits very tightly in order to run the upper spray arm. If you don't have the top rack pushed all the way back into the groove/hole that is in the back of the dishwasher, the front door of the dishwasher will pop open mid-cycle and not complete. Now that I have that figured out, I haven't had one problem with this dishwasher. In fact, I can't believe some of the stuff it actually removes from my dishes (dried, cooked on egg on AllClad, anyone?). I've also seem complaints that the dishwasher doesn't dry very well. Mine seems fine, but I guess I've never had a dishwasher that dries the dishes like the Sahara, although it definitely matters what you have in the load as to how dry they get: i.e. regular plates and glasses, the load is completely dry. 13 x 9 pans and lots of things that seem to block flow in the dishwasher, definitely not dry.

All in all I love the dishwasher, but I can't believe this is the design Samsung went to market with. Now that I have it down and have done it so many times, it's not difficult at all to get the top rack fit correctly, but at first it was very frustrating and I thought I had wasted my money on this product. I can fully understand the negative reviews, but if you are tempted to give one because you think your latch is failing, go back to your dishwasher and try that top rack again. I mean, get on your knees and look inside your dishwasher to see the fit at the back of the top rack so you see what I am talking about. I am telling you it is worth it not to sit on the phone with Samsung customer service AND you will have a dishwasher that cleans your dishes like nobody's business. I love this dishwasher. I am lazy. I don't rinse anything and just put it inside, and 98% of the time everything in the load comes out spotless. Give it another try and see how it goes.
