broken concrete cause of basement leaking?

I'm trying to help my dad out with a problem. All walls of their basement are getting water coming in. A company came out and did a trench drain deal inside along 2 walls. It cost about $3k and would be another 7K to do all walls. (they only did 2 cuz that's all they could afford) My concern is he has a large chunk of his driveway that cracked and is pointing downward by several inches, maybe even about a foot right up against the foundation. Out of the 2 companies he's consulted no one mentioned that it was an issue in the basement leaking. I'm trying to convince him it probably is a huge issue, am I wrong? Just want to say the house is 8 years old, graded perfect from what I can tell, gutters don't leak, has a sump and supposedly was tiled below the footings during construction. The very close neighbors haven't had any issues. He does have a hairline crack in the floor. I know this is really a hard one to speculate on but thanks for any opinions!

Basement leak

When you say the driveway has dropped several inches at the house, it leads me to think there may be a void under the concrete that is collecting water and feeding the leak in the basement. Tap the concrete to listen for hollow sounds. Voids exist under all slabs that meet a vertical wall because of the soil settling.
