Bluetooth, being one of the most popular wireless technologies, enables drivers to integrate their smartphones seamlessly with the car’s entertainment and communication systems. However, just like any technology, Bluetooth connections can encounter hiccups, leading to issues such as pairing failures, audio interruptions, and dropped connections. Understanding the underlying causes and knowing how to troubleshoot these problems is essential for a smooth and enjoyable driving experience.


1. Bluetooth is disabled

Verify Bluetooth is enabled in the smartphone

Before delving into complex troubleshooting steps, it’s essential to start with the basics. Ensure that Bluetooth is enabled on your iPhone or Android device. For most smartphones, you can access the Bluetooth settings through the quick settings menu or the main settings app. Turn on Bluetooth and keep your smartphone’s Bluetooth screen open as as you connect your phone to the infotainment system of Elantra.

On iPhone, go to Settings > Bluetooth.

Verify Bluetooth is enabled in Elantra

The next crucial step is to confirm that Bluetooth is enabled in the infotainment system of your Elantra. Access the infotainment system’s settings and navigate to the Bluetooth or phone menu. Make sure it is turned on, and the infotainment system is actively searching for nearby devices.

2. Forget old pairings

If your smartphone has been connected to multiple Bluetooth devices in the past, it might be trying to connect to a previously paired device instead of your Elantra infotainment system. To resolve this, go to your smartphone’s Bluetooth settings and look for any previously paired devices. Select “Forget” or “Unpair” for all the listed devices except your car’s infotainment system.

3. Restart Devices

Sometimes, Bluetooth connectivity issues can be resolved by a simple restart. Turn off both your smartphone and the infotainment system of your Elantra. Wait for a few seconds and then turn them back on. This process can help clear any temporary glitches that might be affecting the Bluetooth connection.

To restart your iPhone, locate the Power button, which is typically on the right side of the device for newer models or on the top edge for older ones. Press and hold the Power button and either volume button until the “slide to power off” slider appears on the screen. Drag the slider from left to right to power off the iPhone. After it shuts down, wait for a few seconds, and then press and hold the Power button again until the Apple logo appears, indicating that the iPhone is restarting. Release the Power button once the logo is visible, and your iPhone will complete the restart process.

4. Re-pair your phone

Re-pairing your phone with your Hyundai Elantra can be an effective solution for resolving persistent Bluetooth connectivity issues. Re-pairing essentially establishes a fresh connection between your smartphone and the car, which can help to clear any underlying glitches or conflicts.

To reset network settings on a Samsung device, follow these steps: Go to “Settings,” then select “General Management” and tap on “Reset.” From the reset options, choose “Reset Network Settings.” Confirm the action, and the device will reset all network-related settings to their default configurations. This process will erase saved Wi-Fi networks, Bluetooth pairings, and mobile data settings.

After resetting the network settings on your smartphone, you will need to reconfigure some network-related settings, such as Wi-Fi passwords and Bluetooth pairings. Make sure to pair your smartphone with the infotainment system of your Elantra again and test the Bluetooth connectivity to see if the issue has been resolved.

Keep in mind that while resetting network settings can often fix connectivity issues, it may not always solve the problem, especially if the issue is hardware-related. If Bluetooth problems persist after trying this step, consider exploring other troubleshooting options.

6. Update Firmware and Software

Outdated firmware and software can lead to compatibility issues, resulting in Bluetooth problems. Check your car manufacturer’s website and your smartphone’s settings for available updates. Keeping both devices up-to-date can often resolve Bluetooth connectivity problems.

To update iOS on an iPhone, first, ensure you have a stable internet connection, and then connect your iPhone to a Wi-Fi network. Next, go to “Settings” on your iPhone and tap on “General.” From there, select “Software Update.” Your iPhone will check for the latest iOS update available. If an update is found, tap “Download and Install.” If prompted, enter your passcode.

Make sure your iPhone has enough battery life or keep it plugged in during the update. Once the download is complete, tap “Install” to begin the update process. Your iPhone will restart, and after a short while, the new iOS version will be installed, giving you access to the latest features, improvements, and bug fixes.


7. Factory reset the infotainment system

Performing a factory reset on your Elantra infotainment system can be a viable solution to resolve persistent and complex Bluetooth issues that are not resolved through other troubleshooting methods. A factory reset will restore the system to its original settings, potentially clearing any software-related problems that were affecting the Bluetooth functionality. However, it’s important to remember that a factory reset will erase all personalized settings and data, so it should be considered as a last resort after trying other troubleshooting steps.

8. Try any other phone

If you’re experiencing Bluetooth connectivity issues in your Hyundai Elantra, trying a different phone can be a valuable troubleshooting step to isolate the problem. By connecting a different phone, whether it’s an iPhone or an Android device, you can determine whether the issue lies with your original smartphone or if it’s related to the car’s infotainment system.

Once the pairing process is complete, test the Bluetooth connection with the other phone. Make a hands-free call, play music, and use other Bluetooth functionalities to see if everything works as expected. If the connection works flawlessly with the other phone, it suggests that the issue might be with your original smartphone.

9. Hard reset your Elantra

Disconnecting the main 12 volt battery of your Elantra for about 15 minutes is another potential solution to resolve certain issues, including Bluetooth connectivity problems in the car’s infotainment system. This process is known as a “hard reset” and can help to clear any temporary glitches or errors that might be affecting various electronic systems in the vehicle, including the infotainment system.

Identify the Negative Terminal

The negative terminal on the battery is marked with a minus (“-“) sign and is usually colored black. Take note of its location.

Disconnect the Negative Terminal

Use a wrench or pliers to loosen and remove the bolt or clamp that secures the negative terminal to the battery post. Once loosened, carefully lift the negative terminal away from the battery post.

Wait for 15 Minutes

After disconnecting the negative terminal, leave the car’s battery disconnected for approximately 15 minutes. This will allow any residual electrical charge to dissipate and ensure a complete reset of the car’s electronic systems.

Reconnect the Negative Terminal

After the 15 minutes have elapsed, reattach the negative terminal to the battery post and tighten the bolt or clamp securely.

Start your Elantra

With the battery reconnected, start the engine of your Elantra and let it run for a few minutes. During this time, various electronic systems, including the infotainment system, will initialize and reestablish connections.

Test Bluetooth Connectivity

Once the car is running, test the Bluetooth connectivity by pairing your smartphone with the infotainment system of your Elantra and using various Bluetooth features to ensure everything works correctly.

Remember that a hard reset by disconnecting the battery should be used as a last resort after trying other troubleshooting steps. While it can help in resolving certain issues, it may also result in the loss of some personalized settings in your Hyundai Elantra. If the Bluetooth problem persists or if you are unsure about performing a hard reset yourself, it’s best to seek assistance from a qualified mechanic or an authorized dealer to avoid any potential damage to the vehicle’s electrical system.

10. Hardware issue
