2023-2024 Honda CR-V Shutter Grille Issue Investigation

American Honda Motor Co., Inc. (AHM) has initiated an information collection effort concerning certain 2023-2024 Honda CR-V vehicles. The company is actively investigating customer complaints related to a "warning: shutter grille issue" or a "charging system problem" message appearing on the Multi-Information Display (MID). This effort, detailed in the communication titled "Request for Parts: 2023-2024 CR-V Shutter Grille Inop (ACTION REQUIRED)", aims to gather specific parts from affected vehicles to better understand the underlying cause of this condition before any repair attempts are made.

Symptoms Owners May Experience

Owners of affected Honda CR-V models may observe one of two primary error messages on their vehicle's Multi-Information Display (MID):

• "warning: shutter grille issue"
• "charging system problem"

These messages indicate a potential malfunction within the vehicle's shutter grille system or its associated charging components.

Diagnostic Trouble Codes (DTCs)

For a vehicle to be considered for this parts collection, it must have one of the following Diagnostic Trouble Codes (DTCs) stored in its system:

• P16E8: PGM-FI-Shutter Grille LIN Communication Error
• P16E3: PGM-FI-Battery Sensor LIN Communication Error

These codes indicate specific communication or sensor errors related to the powertrain control module (PGM-FI) and the shutter grille or battery sensor systems.

Conditions for Investigation

AHM is interested in collecting parts only if the vehicle meets several specific requirements. It is crucial that owners and technicians understand these conditions before contacting Honda:

• The vehicle must have one of the DTCs P16E8 or P16E3 stored.
• The shutter grille actuator coupler must not have been unplugged at any point.
• There should be no previous replacement of the Shutter Grille Assembly.
• The vehicle must not have been involved in any collisions.
• No repair attempts should have been made on the vehicle during the current visit where the issue is observed.

These qualifiers ensure that the collected parts provide the most accurate data for Honda's investigation into the Honda CR-V shutter grille problem.

What Honda is Doing

American Honda Motor Co., Inc. is proactively collecting specific components from vehicles that meet the outlined criteria. This is a data-gathering initiative to thoroughly analyze the parts and determine the root cause of the "Honda CR-V shutter grille" issue. This process is essential for developing effective long-term solutions.

What Owners Should Do

If your 2023-2024 Honda CR-V is displaying a "warning: shutter grille issue" or "charging system problem" message, and you believe it meets the conditions listed above (especially regarding the DTCs and lack of prior repairs or unplugging), you should contact your authorized Honda dealership. The dealership will then communicate with Honda's Technical Information & Support (TIS) group to determine if your vehicle qualifies for the parts collection program.

It is important to note that this is an information-gathering effort, not a recall or a standard repair bulletin. Honda is seeking to understand the problem, and participation may involve your vehicle being inspected and specific parts collected for analysis. Dealer personnel who successfully identify and report a qualifying vehicle that leads to a parts collection may receive a VISA gift card as a gesture of appreciation.
