Driveways poured in sub 40 degree weather on a frozen or near Frozen sub grade have a tendency to delaminate or spider crack months later if the finishers got on it to quick and burned it in with floats.

Bingo

Was @ 38deg that morning. I know because I drove by later that day as they were pouring the last one of seven done that day, including mine.
Too much accelerant was probably a reason as well, from what I have been told.

A home I bought in 2008 had the same problem. At the time, I had been a commercial concrete sales rep for 11 years but my builder did not know that concrete was my expertise. I let him give me an entire load of BS before I told him my occupation and told him what I know happened. The driveway was poured in December on a 35 degree morning after it had rained for about 3 days in a row. It was amusing listening to him backtrack and agree to replace the driveway. He ended up charging his sub though.
