Symptoms of a failed active grille:

A broken or damaged active grille.

If the grille fails to open/close, the aerodynamics and cooling performance of the vehicle will be affected.

During a failure of the active grille, the dashboard will display a warning message or a prompt for abnormal cooling system.

Possible reasons for failures of an active grille:

The active grille is located behind the bumper and in front of the impact beam. It has a high rate of damage after collision.

Deformation or cracking caused by long-term use, UV exposure, or environmental factors can lead to failure.

A malfunction of the electronic control system or the sensors will affect normal operation.

Daily maintenance suggestions:

Clean the grille gaps regularly to avoid accumulation of foreign objects, and perform proper deicing in winter.

Avoid modifications not in line with original specifications, choose reliable accessories, and take adequate waterproofing measures.
