Doubt any recourse from the GC or the company who poured it. There's many factors of what might have caused it, but also the OP hasn't shown pics. No sense in outlining a problem list.
But for starters, he's in CO. Exactly when was the slab and then the drive poured? What season, what was the weather like during the pour and the following days? Did it cure too fast in heat? Not kept wet or moist enough during critical first week curing. Or did it freeze? No frost blankets? Did it rain heavily on it?
When did you first note of a potential problem?
What's the sub-base? Compacted + pea gravel, plastic laid? Fiber screened crete? Metal mesh used / rebar?
Drainage / sub and perimeter of any kind?
Long shot, but did you have a 40 footer moving truck parked on it? Believe me, have seen this more than once and trashed driveways because of. Homeowner then blames the contractor. Movers always reply with a 'screw you'.
Bottom line, you want it fixed. Bust it out, properly prep, confirm drainage, re-pour. Its going to cost big.
