I have a 2020 Hyundai Sonata. The temperature gauge stays on "C" or slightly above. This all started when my check engine light came on. I took the car to a local mechanic. He ran one of those reader machines on it and the only code that came up was for low coolant. So he filled my coolant. After driving it a few times the check engine light went off. However, no matter how long I drive the temperature gauge never goes more than a little above "C". ( no check engine light comes on). What is the most likely cause or causes of the temperature gauge pretty much staying on "C". What should I do next. I have NO mechanical experience whatsoever. Thank you +
