Yeah, that's pretty much the law on potholes, at least in NY. If it hasn't been reported then your SOL. After it's reported the city has 10 days to repair the pothole from the day the report is filed. I found this out 2 years ago the hard way when my 9 month old mystique fell into a pothole in Brooklyn and shattered the oil pan and caused a small hairline crack the transmission casing. Cost me 700 bucks for the oil pan and I never got the transmission case fixed. Sorry man....but I think you're on your own on this one.
