This summary uses the existing diagnostic information shown in full below.
The car has a special flap in the front that helps with cooling and aerodynamics. This code means the motor that moves the flap is getting too hot.
The active grill air shutter system helps improve fuel efficiency and engine cooling by opening and closing shutters at the front of the vehicle. Code P3068 indicates that the motor controlling these shutters is overheating.
The Active Grill Air Shutter system is designed to manage airflow through the radiator and engine compartment. The motor responsible for opening and closing the shutters has a built-in temperature sensor. If this sensor detects a temperature above the normal operating range, it triggers the P3068 code.

Check with your vehicle manufacturer to see if the grill shutter system is covered under warranty.
This code has become more common as manufacturers implement active grill shutters to improve fuel efficiency.
Moderate – The vehicle can be driven, but it is advisable to address the issue to prevent potential overheating.
Driving with this issue may lead to reduced fuel efficiency and potential engine overheating.
• Vehicle at operating temperature
• Engine running
The active grill air shutter is located at the front of the vehicle, typically behind the front bumper.
Q: Can I drive with a P3068 code?
A: Yes, but it's best to get it fixed soon to avoid overheating.
Q: How do I know if my grill shutters are stuck?
A: You might notice reduced fuel efficiency or hear unusual noises from the front of the vehicle.
