A large underwater area between continents is called a submarine canyon. These are deep, steep-sided valleys cut into the seafloor by turbidity currents, often connecting continental shelves to the deep ocean. They can be thousands of meters deep and hundreds of kilometers long.

The pressure gets too great and the submarine implodes. The deeper you go under water the more pressure there is.
A structural problem on a submarine may make it possible for that vessel to be crushed as it descends. It may or may not be likely to be crushed, and that would depend on the nature of the problem and how deep the submarine descended.
Deep ocean pressures are to great for submarines. They do not need to go deep anyway, just to avoid detection by the enemy.
