I had a strange issue. I havent been driving much during the COVID-19 lock down, but I am not sure if that makes a difference. For 3 straight days, I made a few short trips in my 2015 Hyundai Elantra. The car is running fine, but when I first start it up I heard this strange gurgling noise, like boiling liquid. The car's temperature was fine and there was no issue driving that I could feel. I also noticed that driving seemed to have no affect on the noise. It would gurgle when I start, I drive for a bit and hit a stop light and the noise was still there. The noise did stop eventually, but I couldnt figure out why. I was sitting at the drive through at Taco Bell and decided to schedule a service appointment listening to the noise. On a whim, I turned my AC and fan on and the noise stopped and hasnt come back since.
Was that all it needed? Or should I still take it in?
