2023-2024 Honda CR-V Shutter Grille Inop Warning

American Honda Motor Co., Inc. (AHM) has issued a communication to its dealerships regarding certain 2023-2024 Honda CR-V vehicles. Owners may observe a "warning: shutter grille issue" or "charging system problem" error message displayed on the Multi-Information Display (MID). This communication, identified as a "Request for Parts: 2023-2024 CR-V Shutter Grille Inop (ACTION REQUIRED)", indicates that Honda is seeking to collect specific parts from affected vehicles to better understand the root cause of this condition.

This proactive data collection aims to gather more information on why the Honda CR-V shutter grille inop condition occurs. It is important for owners to understand the symptoms and conditions that qualify a vehicle for this special investigation.

Symptoms

Owners of 2023-2024 Honda CR-V models might notice one of two primary warning messages appearing on their vehicle's Multi-Information Display (MID). These include a "warning: shutter grille issue" or a "charging system problem" error message. These warnings suggest a malfunction with the active shutter grille system, which helps regulate engine temperature and improve aerodynamics.

If you experience either of these messages, especially if your Honda CR-V shutter grille inop condition is persistent, it is advisable to contact your authorized Honda dealership for diagnosis. The presence of these specific warnings is a key indicator for Honda's ongoing investigation.

Fault Codes (DTCs)

Honda's investigation is specifically interested in vehicles that have stored certain Diagnostic Trouble Codes (DTCs) related to the shutter grille system. These codes provide critical information about the nature of the electrical communication errors.

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

These DTCs indicate issues with the communication lines for the shutter grille and battery sensor, respectively, suggesting an electrical or control system fault contributing to the Honda CR-V shutter grille inop condition.

Qualifying Conditions for Investigation

American Honda Motor Co., Inc. is interested in collecting parts from vehicles that meet specific criteria to ensure the data collected is relevant to their investigation. For a 2023-2024 Honda CR-V to qualify, it must meet all of the following requirements:

• DTCs Present: The vehicle must have either DTC P16E8 (PGM-FI-Shutter Grille LIN Communication Error) or DTC P16E3 (PGM-FI-Battery Sensor LIN Communication Error) stored.
• Shutter Grille Actuator Coupler Status: The shutter grille actuator coupler must NOT have been unplugged at any point.
• Previous Repairs: There should have been no prior replacement of the Shutter Grille Assembly.
• No Collisions: The vehicle must not have been involved in any collisions.
• No Prior Repair Attempts: No repair attempts for this specific issue should have been made during the current visit to the dealership.

These conditions help Honda narrow down the scope of their investigation to vehicles that present the issue in its original, unaltered state.

Honda's Investigation and Data Collection

To better understand the cause of the "warning: shutter grille issue" or "charging system problem" error messages, Honda is requesting that dealerships identify and report vehicles that meet the specific qualifying conditions. The goal is to collect specific parts from these vehicles before any repair attempts are made. This allows Honda engineers to analyze the components in their as-failed state, which is crucial for accurate diagnosis and potential future remedies.

Dealerships are instructed to email Technical Information & Support (TIS) with details such as the model year, model name, issue description, VIN, dealer number, and current mileage. This ensures that Honda can track and manage the collection of parts efficiently.

What Owners Should Do

If you own a 2023-2024 Honda CR-V and experience a "warning: shutter grille issue" or "charging system problem" message on your Multi-Information Display, you should contact your authorized Honda dealership. Inform them about the specific warning messages and any other symptoms you've observed. While this is not a recall, it is an active investigation by Honda to understand and resolve a potential issue affecting the Honda CR-V shutter grille inop condition.

Your dealership will be able to check for the relevant DTCs (P16E8 or P16E3) and determine if your vehicle meets the specific qualifiers for Honda's parts collection program. Following your dealer's advice is the best course of action.

Important Warning

American Honda Motor Co., Inc. has specifically instructed dealerships that they wish to collect specific parts from qualifying vehicles prior to any repair attempt. This means that if your vehicle meets the criteria, your dealer should not attempt to repair the shutter grille or related systems before contacting Honda's Technical Information & Support (TIS) team.
