If the 2018 Honda CR-V experiences problems with its power tailgate, follow these steps to troubleshoot and possibly resolve the issue:

Check the Power Tailgate Switch

• Ensure the power tailgate switch inside the vehicle is not turned off. It is typically located on the dashboard or near the driver's seat.
• If the switch is off, turn it on and try to operate the tailgate again.

Inspect the Key Fob

• Verify that the key fob battery is not dead. A weak or dead battery can prevent the power tailgate from responding to remote commands.
• Replace the battery if necessary and try to use the key fob to open the tailgate again.

Check for Obstructions

• Inspect the tailgate area to ensure there are no physical obstructions preventing it from opening or closing.
• Remove any objects that may be in the way and try to operate the tailgate again.

Reset the Power Tailgate

• Turn off the vehicle’s ignition and close all doors.
• Disconnect the negative battery terminal and wait for about 15 minutes.
• Reconnect the battery terminal and try to operate the power tailgate again.

Check for Fault Codes

• Use an OBD-II scanner to check for any fault codes that may be related to the power tailgate mechanism.
• If any codes are present, refer to the vehicle’s service manual for guidance on how to address them.

Inspect Fuse and Wiring

• Locate the fuse box and find the fuse related to the power tailgate.
• Check the fuse to ensure it is not blown. Replace it if necessary.
• Inspect the wiring connected to the power tailgate for any signs of damage or disconnection.

Consult a Professional

• If the above steps do not resolve the issue, consult a certified Honda technician for a more thorough diagnosis.
• A professional may need to inspect the tailgate motor, sensors, and control module to determine the cause of the problem.
