I opened the hood to check engine oil, and saw hot coolant sprayed all over under hood. Coolant level was very low. Upon closer examination, there's a crack in the top plastic of the radiator from which coolant was spraying out before I turned the engine off. This is a safety issue both due to the potential of burns/scalding, but also engine damage and fires while traveling due to low coolant. Further research revealed this is a very common problem at 6-8 years of age and around 100,000 miles. I can't upload a photo since I've had it cleaned and repaired to make it drivable (at my expense).
