I would say its likely to be a highly reactive soil such as clay and as it get wet and dry it expands and contracts expedentially. Firstly if you do have a leaking pipe you can check for yourself very easily: (1) Turn every tap off in your home, washing machine, toilets the works (2) Now go and check the water meter and see if its still running, as in: are the numbers going around? if so that generally means you have a water leak somewhere. My next step would be to employ the services of a leak detector and he will be able to tell you if there is a leak under your slab, and which way it is spraying and how deep under the ground it is. I have used these many times and they have always been deadly accurate. Failing this and there is no leak, employ the services of a geo tech engineer to do soil testing and possibly even a few bore holes, as there may be a water table beneath where your garage is, and due to ground pressure it may be rising to the surface, but they would be able to shed more light on that than me without seeing it first.

Moisture coming from the ground First problem in nothing to worry about. In fact you have photos of cracks in corners where two walls meet this is very common place for cracks to occur. You also have cracks along a pier one brick wide this is a very uncomman place for cracks to occur o i am of the belief that it is just the render cracking. This may be the case with a lot of the render cracks. Crack on the ground - hard to see in the pics however from what can be seen are nothing to worry about. 2. Moisture from ground is more a concern for me and thats only if it is comming from a service or drainage. Chances are it is not mains water because this is not unsually run through the slab. The only thing i can forsea under the slab in the garage is drainage storm water. However i do not know enough about your house. Perhaps you give trade link a call pay the fee and they will send you a drainage plan of your house. Secondly is the garage below ground level. ALso how many times have you seen this water in the garage. Have you tried to dry it out and see if it returns?? Please treat both issues seperately otherwise you will confuse the situation.
