2023-2024 Honda CR-V Shutter Grille Inop Issue

Background: The Honda CR-V Shutter Grille Issue

American Honda Motor Co., Inc. (AHM) has initiated an investigation into certain 2023-2024 Honda CR-V vehicles. Owners of these vehicles may experience a Honda CR-V shutter grille issue, often accompanied by specific warning messages on the Multi-Information Display (MID). To thoroughly understand the underlying cause of this condition, AHM is actively collecting parts from affected vehicles.

This proactive measure, outlined in the manufacturer communication "Request for Parts: 2023-2024 CR-V Shutter Grille Inop (ACTION REQUIRED)", aims to gather crucial data before any repair attempts are made. The goal is to prevent unnecessary repairs and accurately diagnose the problem.

Symptoms Owners May Experience

Owners of affected 2023-2024 Honda CR-V models might observe one of two primary error messages displayed on their Multi-Information Display (MID). These messages indicate a potential problem with the vehicle's active shutter grille system or related components.

The specific verbatim messages that may appear are: "warning: shutter grille issue" or "charging system problem". These warnings suggest that the shutter grille may not be operating correctly, which can impact vehicle aerodynamics and engine temperature regulation.

Associated Diagnostic Trouble Codes (DTCs)

When the Honda CR-V shutter grille issue occurs, technicians may find specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's system. These codes help pinpoint the area of concern.

Code	Description
P16E8	PGM-FI-Shutter Grille LIN Communication Error
P16E3	PGM-FI-Battery Sensor LIN Communication Error

These DTCs indicate communication problems within the PGM-FI (Programmed Fuel Injection) system related to either the shutter grille or the battery sensor, both of which utilize the LIN (Local Interconnect Network) communication protocol.

Does Your CR-V Qualify for Honda's Investigation?

AHM is interested in collecting parts only from 2023-2024 Honda CR-V vehicles that meet specific criteria. If your vehicle exhibits the Honda CR-V shutter grille issue and meets these conditions, it could contribute valuable data to Honda's investigation.

Your vehicle must satisfy all of the following requirements:

• It must have one of the following DTCs stored: P16E8 (PGM-FI-Shutter Grille LIN Communication Error) or P16E3 (PGM-FI-Battery Sensor LIN Communication Error).
• 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 to the dealership.

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 qualification criteria for Honda's investigation, it is important to contact your authorized Honda dealership. Do not attempt any repairs yourself or allow unauthorized repair attempts.

Your dealer will then contact Technical Information & Support (TIS) at [email protected] or by phone at 800-880-1072 (Monday-Friday, 7am-5pm PST). TIS will provide further instructions regarding the collection of vehicle information and specific parts. It is crucial that no repair attempts are made prior to TIS involvement, as this could compromise the investigation.
