Recently I wanna say right when it started getting really cold i’d warm my car up for work in the morning (around 5:45am) get in and perfectly warm right, start driving to get on the road and not even minutes later it would start blowing freezing air. Didn’t know what to do except get to my location than call the dealership when they open. After work that day I just decided to drive it again and see if it was just a morning problem being so cold but it was worse so I pop the hood when I get home and both coolant tanks were below low one seriously low. The shop fixed it not problem and told me there was an air pocket I can’t remember where but it wasn’t allowing heat into the cabin but they said other hyundais have came in for the same problem recently and can’t give me a good explanation on the coolant being low either. Just curious if anyone else experienced this recently, Thanks🙂
