2023-2024 Honda CR-V Shutter Grille Issue P16E8 P16E3

What Honda is Investigating

American Honda Motor Co., Inc. (AHM) has initiated an investigation into a specific concern affecting 2023-2024 Honda CR-V vehicles. Owners may observe a "warning: shutter grille issue" or "charging system problem" error message displayed on their vehicle's Multi-Information Display (MID). To better understand the root cause of this condition, Honda is requesting dealers to identify and facilitate the collection of specific parts from affected vehicles.

This communication, identified as a "Request for Parts: 2023-2024 CR-V Shutter Grille Inop," is an internal dealer message. It aims to gather data and physical components before any repair procedures are developed or released. The goal is to thoroughly analyze the issue and determine the most effective solution for the Honda CR-V shutter grille problem.

Symptoms and Diagnostic Trouble Codes (DTCs)

Owners of the affected Honda CR-V models may experience specific warning messages on their Multi-Information Display (MID). These include the verbatim phrases: "warning: shutter grille issue" and "charging system problem". These messages indicate a potential malfunction within the vehicle's shutter grille system or related components.

Technicians diagnosing this condition are likely to find one of the following Diagnostic Trouble Codes (DTCs) stored in the vehicle's system:

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

These DTCs point to communication errors within the powertrain control module (PGM-FI) related to the shutter grille and/or battery sensor systems.

Conditions for Part Collection

Honda is interested in collecting parts only from 2023-2024 Honda CR-V vehicles that meet specific criteria. For a vehicle to qualify for this part collection initiative, it must exhibit one of the aforementioned DTCs (P16E8 or P16E3). Additionally, several other conditions must be met:

• The shutter grille actuator coupler must not have been unplugged.
• 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 during the current service visit related to the Honda CR-V shutter grille issue.

These strict qualifiers ensure that the collected parts provide the most accurate data for Honda's investigation into the problem.

Important Note for Owners

This communication is an internal request from Honda to its dealerships for information and parts. It is not a recall notice or a standard Technical Service Bulletin (TSB) that outlines a repair procedure. Owners are not being directly notified by Honda for this specific part collection request. If your 2023-2024 Honda CR-V is experiencing the described symptoms or DTCs, it is important to understand that Honda is currently in an investigative phase.

Owners should be aware that Honda advises against attempting repairs of any kind until a formal solution is provided. This is to ensure that the integrity of the affected components is maintained for proper analysis.

What to do if your 2023-2024 Honda CR-V is Affected

If your 2023-2024 Honda CR-V displays a "warning: shutter grille issue" or "charging system problem" error message on the MID, and you suspect it might be related to DTCs P16E8 or P16E3, you should contact your authorized Honda dealership. Inform them about the specific error messages you are seeing and any diagnostic trouble codes that may have been identified.

While this is not a repair campaign, your dealership can determine if your vehicle meets the specific qualifiers for Honda's part collection initiative. Cooperating with this investigation can help Honda develop a permanent solution for the Honda CR-V shutter grille problem.
