I recently brought my 2018 civic sport into Honda because I noticed that the engine never warms up to operating temperature. In fact, it barely warms up at all at idle. When I drive it, it warms up fine, but then when I stop for a few minutes, it drops alarmingly fast back down to almost nothing. Honda told me this was \”normal\” as new cars try to run \”as cold as possible.\” I know a lot about engines and I have never seen anything like it before. The car is brand new. Please advise if this is something to worry about, to me it seems to show symptoms of a stuck thermostat.
