Today I was walking in my basement and found this right below my window. I took a picture from the outside too. Is this a normal hairline crack? Foundation is only 15 months old...
House is settling, ground shifting, unstable soil, happens here all the time. It's the norm in our area. If it continues to grow larger then contact your builder and/or the sales person who sold you the home and see what they tell you.
I had the same issue (the crack was almost exactly like your pic, maybe a little wider on the outside) - house was built in 2007 and I moved in last yr. I saw a couple drops of water come thru the inside crack when Sandy came thru (lots of rain).
I went and bought a tub of 'hydradulic cement' and patched the outside (left the inside untouched). I dig away the soil as deep as I can go and brushed the surface a bit to clean the mud off. I didn't chip at the crack before applying the cement on exterior crack. Well, it's now a yr later and I don't see the crack re-appear. Also, during heavy rain, there hasn't been any water coming thru the inside crack either.
If you can contact the builder, go for it. For me, I won't know where to even start finding the company that built my place. I also looked up other methods, like polyurethane injection... it sounded like those are for serious cracks and I thought mine was minor enough to try DYI first.
Nobody mentioned "shrinkage crack" in this thread-
How did you know? Or can I just chalk this up to "let's play dumb and see what kind of answers I get"?

Or, chalk this up to contractors that don't run steel mesh in multiple dimensions. Had numerous contractors walk away from the last houses (I had built only foundation and roofing, I did the rest). Cost dominates quality. please prove me wrong. (as then I will have the slightest respect for contractors).
Don't ever let a contractor talk you out of correcting bad work. I have kicked my self for letting my pool contractor finish off my pool when the plumbing didn't hold 30lbs of pressure for 24 hours. Now my pool leaks and the company went out of business. The foramen was a slick talker he had all these things to blame it on in reality he just didn't want to lose money trying to find the leak.
Eh...I meant normal hairline crack... Sorry. Should I have it fixed even if I don't have any water intrusion?

Don't apologize to these people. Shrinkage cracks occur for two reasons. Either the driver was told to add water too make finishing easier, or moisture wasn't maintained properly during the curing process. Properly mixed, and cured concrete may crack after a few years, but too see it in such a short timeframe shows ignorance on those who placed it originally, or intentional malfeasance. Ignorance of the construction industry is rampant due to lack of understanding of proper process, and installation, and or lack of proper education.
