Can You Drive with a Bad Active Grill Shutter

If you’re wondering if driving with a faulty active grille shutter is safe, you’re not alone. This is a usual question amongst drivers who may not be conversant with this car piece. In this guide, we will give a break down of everything you need to know about active grille shutters— what they are, why they’re important, and what to do if yours malfunctions.

What Is an Active Grille Shutter?

An active grille shutter (AGS) is a feature in modern vehicles that helps boost aerodynamics and fuel efficiency. Located in front of the radiator, these shutters open and close automatically based on the car’s speed and engine temperature. When closed, they reduce drag, enhancing fuel economy. When open, they let cool air reach the engine, preventing overheating.

Why Are Active Grille Shutters Important?

Active grille shutters are crucial for your vehicle’s performance and efficiency. Here’s why:

• Effective Fuel: AGS systems improve fuel efficiency by reducing air drag.
• Engine Temperature Control: They help regulate engine temperature by controlling airflow.
• Enhanced Aerodynamics: AGS systems contribute to a smoother aerodynamic profile, especially at high speeds.

Can You Drive with a Bad Active Grill Shutter?

Yes, you can drive with a bad active grill shutter, but it’s not recommended for an extended period. A malfunctioning AGS can lead to several issues, including:

1. Reduced Fuel Efficiency: If the shutters are stuck open, you may notice a slight drop in fuel efficiency due to increased drag.
2. Engine Overheating: If the shutters are stuck closed, they may prevent adequate airflow to the radiator, leading to overheating issues.
3. Check Engine Light: A faulty AGS can trigger the check engine light, indicating a problem that needs to be addressed.

Can You Drive with a Faulty Active Grille Shutter?

Yes, it’s possible to drive with a malfunctioning AGS, but it’s best to avoid it for extended periods. A faulty AGS can lead to issues such as:

• Reduced Fuel Efficiency: Stuck shutters can cause little drop in the efficiency of fuel due to increased drag.
• Overheating Engine : Shutters stuck in the closed position can restrict airflow to the radiator, causing overheating.
• Warning Lights: A faulty AGS often triggers the check engine light, alerting you to a potential problem.

Signs of a Bad Active Grille Shutter

Here are some indicators that your active grille shutter might need attention:

• Check Engine Light: The AGS is connected to your vehicle’s computer system, which may trigger a warning if there’s an issue.
• Warning Noises: Clicking or rattling sounds from the front of the car can point to mechanical issues with the shutters.
• Shortage in fuel: A noticeable drop in fuel economy could mean the shutters are stuck open, causing more drag.

In an emergency, if your AGS fails while you’re far from a repair shop, monitor the engine temperature gauge closely. If the engine overheats, pull over and let it cool before continuing.

Symptoms of a Failing Active Grille Shutter

Below are some of the usual signs of a malfunctioning AGS:

• Warning Lights: The check engine light may come on due to AGS-related issues.
• Lower Fuel Efficiency: Stuck shutters can increase aerodynamic drag, leading to reduced fuel efficiency.
• Overheating: If shutters are closed and blocking airflow, the engine may overheat.
• Different Noises: Stuck shutters might produce unusual noises from the front of the vehicle.
• Error Codes: Mechanics can use an OBD-II scanner to read diagnostic trouble codes (DTCs), identifying precise AGS issues.

Where to Get an Active Grille Shutter Fixed

If you think your active grille shutter is malfunctioning, get it checked by a qualified mechanic. Authorized dealerships and specialized auto repair shops can diagnose and fix AGS problems. Costs differ depending on the vehicle make and model, but to rectify this repair is generally affordable.

Cost of Repairing an Active Grille Shutter

Repair costs can range from $300 to $1,000, depending on factors like the vehicle type and the extent of the damage.

• Parts Cost: Replacing shutters or the motor might cost $150–$500.
• Labor Cost: Labor fees vary, typically between $100 and $500, depending on the complexity of the repair.

Conclusion: Should You Risk It?

Technically, you can drive with a bad active grille shutter, but doing so could lead to lower fuel efficiency, potential engine overheating, and other complications. If you notice any AGS-related issues, it’s wise to get them checked and repaired to keep your vehicle in optimal condition.

Knowing how an active grille shutter functions, why it’s important, and how to handle malfunctions will help you maintain your vehicle’s health. Timely maintenance can prevent bigger issues in the future.
