I doubt there is anything to repair, small 4 cylinder engines don’t generate a lot of heat. It may take 15 minutes to reach operating temperature while driving at slow speeds if there is a high heat load from the heater.

Assuming there is a problem it could be either a bad thermostat or low coolant. Honestly, I wouldn’t expect either on a vehicle this new but stranger things have happened. As the others have said, have it fixed under warranty.

Could also be an improperly installed thermostat.
At any rate, use the warranty.

You would think the manufacturing process has perfected that by now.
