Coolant loss. possible bad radiator cap?
I have a 2017 Hyundai Accent with about 104k miles. I decided now that the warranty is up I'd be doing my own servicing to the engine as opposed to taking it somewhere. So while checking the oil I figured id check the coolant level. My overflow was sitting at the low level. I know the last time it was filled was last year.
The car doesn't overheat or have any signs of coolant leaks. But when taking the radiator cap off i noticed there was some white buildup around the seal on the rad cap and the filler neck seal. I checked after the car was off for about 15-20 minutes and there didn't seem to be any pressure behind the cap. So the engine was still kinda warm just not operating temp.
Im leaning towards a bad radiator cap but I thought id check with yall first.

The coolant looks good. No signs of head gasket failure. I cleaned the white crud from around the seal on the cap and filler neck. I topped off the coolant as well. When i checked yesterday it did have a little bit of pressure that was released when I loosened the cap. Im going to drive it and check the coolant again this week to see if there is any drastic change in the level.
