Many Hyundai Elantra owners have reported experiencing random USB connection interruptions, leading to pauses in music playback or dropped phone calls.

This repair focuses on replacing the faulty USB port module with a new genuine part, ensuring a reliable connection for your devices.

Before we begin, it’s important to understand that this guide is for informational purposes. While we aim to provide accurate and helpful instructions, car repairs are inherently DIY tasks come with risks. If you are not comfortable working with car electronics or removing trim pieces, it’s always recommended to seek professional assistance. However, if you’re comfortable with basic car maintenance and want to tackle this common Hyundai Elantra issue, follow these steps carefully.

Identifying the Problem: Symptoms of a Faulty USB Port

Before diving into the repair, let’s confirm if a USB port replacement is indeed the solution. Common symptoms of a failing USB port in your Hyundai Elantra include:

• Intermittent Disconnection: Your phone or USB device randomly disconnects and reconnects while plugged in.
• No Connection: Your car infotainment system fails to recognize any device plugged into the USB port.
• Charging Issues: Your device is not charging consistently or at all when connected to the USB port.
• Error Messages: The infotainment system displays error messages related to USB connection.

If you are experiencing these issues, especially the intermittent disconnections, replacing the USB port module is likely to resolve the problem.

Tools and Parts You’ll Need

To complete this repair, you will need the following tools and parts:

• New USB Port Module: Part number 96120-GI000 (verify compatibility with your specific Hyundai Elantra model year). You can order this part from online Hyundai parts retailers or your local dealership.
• Flathead Screwdriver: For removing plastic clips and trim pieces.
• 10mm Socket Wrench: For removing a bolt securing the trim.
• Optional: Trim Removal Tools (Plastic Pry Tools): While a flathead screwdriver can work, plastic pry tools are designed to minimize damage to trim pieces.
• Light Source (Phone Flashlight or Headlamp): To see clearly in the footwell area.

Step-by-Step Guide to Repairing Your Hyundai Elantra USB Port

Now, let’s get into the step-by-step repair process. Remember to work in a well-lit area and take your time.

Step 1: Accessing the USB Port Area

The USB port in the Hyundai Elantra is typically located in the center console area, near the gear selector and 12V power outlet. We need to access the underside of this trim piece to replace the USB port module.

Step 2: Removing the Trim and Cubby

1. Remove Plastic Clips: Locate the two plastic clips on the left and right sides of the floor trim piece surrounding the center console. Use a flathead screwdriver to gently pry up the center of each clip. Once the center is raised, the entire clip should easily pull out.

2. Remove Felt Cover and Bolt: Locate the felt cover inside the cubby area. Use the flathead screwdriver to lift the edge of the felt and remove it. Beneath the felt, you will find a 10mm hex head bolt. Use your 10mm socket wrench to remove this bolt.

3. Release Trim Piece Clips: With the clips and bolt removed, the plastic trim piece should be loose. Gently rock the trim piece back and forth to disengage the four plastic clips located at the top. Apply gentle pressure on the sides while rocking to help release the clips. Be careful not to yank forcefully, as there are wires connected to the USB port and 12V adapter.

4. Disconnect 12V and USB Harnesses: Once the trim piece is loose and you can access the underside, locate the 12V adapter harness and the black rectangular USB harness. Unclip the 12V adapter harness. For the USB harness, push the clips on both sides to release it from the trim piece. You can refer to your new USB port module to see where these clips are located. Once both harnesses are disconnected, you can remove the trim piece completely and set it aside.

Step 3: Disconnecting the Old USB Port

1. Disconnect White Harness: With the trim piece removed, you’ll see two connectors attached to the old USB port module: a white harness and a blue harness. Disconnect the white harness – it’s typically easier to detach.

2. Access and Disconnect Blue Harness: The blue harness connector is located further under the dash and can be a bit more challenging to reach. You may need to loosen the center trim piece of the lower dash to gain better access. Gently tug on the bottom right corner of the center trim piece next to the steering wheel to loosen it slightly. This will create some space to reach the blue connector.

3. Locate and Depress Blue Harness Clip: Lie down in the passenger footwell with your head towards the front of the car for optimal access. Use a light source to illuminate the area under the dash. Locate the blue harness connector. It is connected to a silver component with multiple harnesses. The blue connector is the rightmost plug (towards the driver’s side). Examine your new USB port module to understand the clip mechanism on the blue connector. You need to depress the top part of the clip to release the connector. This step may require some patience and dexterity, especially in a confined space.

Step 4: Connecting the New USB Port

1. Connect New Blue Harness: Once the old blue harness is disconnected, take your new USB port module and connect the blue harness to the now-open plug. Ensure it clicks securely into place. Pay attention to the orientation of the connector before inserting it – the clip part should face away from you.

2. Connect New White Harness: Connect the white harness from the new USB port module to its corresponding connector.

3. Route and Secure Wire: Route the wire of the new USB port module back under the plastic dash trim and re-insert the wire into the plastic clip near the red marker on the wire (if present on your vehicle’s wiring).

Step 5: Reassembling the Components

1. Reinstall Center Dash Trim (if loosened): If you loosened the corner of the center dash trim piece, pop it back into place.

2. Reconnect USB and 12V Harnesses to Trim Piece: Take the center console trim piece and reconnect the white harness and the USB harness to the new USB port module. Ensure you align the USB port correctly (there may be a “TOP” sticker to guide orientation). Reconnect the 12V power adapter harness as well.

3. Reinstall Trim Piece: Carefully align the center console trim piece and pop it back into place, ensuring the four white clips at the top engage properly.

4. Reinstall Bolt, Felt Cover, and Plastic Clips: Reinstall the 10mm bolt in the cubby area and tighten it. Replace the felt cover over the bolt. Finally, reinsert the two plastic clips on the left and right sides of the trim piece.

Testing Your Repair

Start your Hyundai Elantra and test the USB port. Plug in your phone or a USB drive and check if the connection is stable and if your device is charging and functioning correctly with the infotainment system.
