Cause #1: Software Update Is on the Way

If you are experiencing the “Park Assist Unavailable” error message on your Tesla, it could be due to a software update that is on the way. This error message often appears when the software needs to be downloaded to the car. In this case, you should wait for the update and download it on the car’s screen and Tesla App.

How to Fix?

To fix this issue, you can follow these simple steps:

1. Open the Tesla App on your phone and click on “Software Update” > “Install” or “Yes”.
2. The car’s screen will start processing to begin the update, and the time will be shown in the Tesla App.
3. Let the update download completely.
4. On the touchscreen, go to “Controls” > “Software” > “Update Available” > “Software Update” (orange/yellow alarm icon).
5. Wait for the update to download completely.

Once the software update is complete, the “Park Assist Unavailable” error message should disappear. Keep in mind that it may take some time for the update to fully install and for the error message to disappear.

Cause #2: System Malfunctions

Another reason why Tesla Park Assist may be unavailable is due to internal system bugs that cause this feature to not work. In this case, a soft reset and power off of the car may fix the error.

How to Fix?

To perform a soft reset, the driver should use the 2-scroll buttons on the steering wheel or yoke (based on model and configuration) for 10 seconds. Afterward, they should wait for the screen to go black and return.

Next, the driver should navigate to Controls > Safety and Security or Safety > Power Off option. Then, click on the Power Off bar and the car will go blank.

It is important to not touch any parts inside the car and let it be like this for 2 – 3 minutes. Then, press the brake pedals to wake it up. For a detailed explanation of the soft reset, check out the 2 button reset methods here.

If the issue persists, it may be a hardware malfunction, and the driver should consider making a service appointment with a certified technician for diagnosis and repair.

Cause #3: Dirt Near the Front Ultrasonic Sensor

When dirt, debris, or snow accumulates near the front ultrasonic sensor, it can obstruct the sensor’s view and cause the Park Assist feature to become unavailable. This can be frustrating for Tesla owners, but fortunately, the fix is relatively simple.

How to Fix?

To fix this issue, Tesla owners can follow these steps:

1. Obtain a soft lint-free cloth.
2. Wipe the sensor area in a circular motion to remove any dirt, debris, or snow.
3. Tap the sensor gently to dislodge any small rocks or debris that may be stuck near the sensor.
4. Avoid using any sharp objects or cleaning solutions as these can harm the sensor.
5. Remove any stickers or accessories installed near the sensor as these can block the sensor’s view.

By following these steps, Tesla owners can ensure that their front ultrasonic sensor is clean and unobstructed, allowing the Park Assist feature to function properly.

Cause #4: Disconnected or Faulty Front Ultrasonic Sensor

If the front ultrasonic sensor is either disconnected or faulty, it can cause the Park Assist to become unavailable. In such cases, you need to locate the sensor’s spot and tighten the red plug.

How to Fix?

To fix the issue, you can follow these simple steps:

1. Start by listening to the chime noise near the front ultrasonic sensor. If you don’t hear any sound, it indicates that either the sensor is bad or the wire harness is disconnected.
2. Power off the car before doing anything. Then, open the hood and take out the top storage panel.
3. Using a 10mm socket wrench, detach all the bolts from the storage cargo. Make sure to remove the rubber bolts with needle-nose pliers.
4. Detach the plug that goes to the board of storage cargo. Then, take out the storage cargo and keep it in a safe spot.
5. Locate the front ultrasonic sensor on the left side of the car, which is easy to spot. Press the sensor until it comes out from the frunk area.
6. Once you find the red and black wire harness plug attached to the sensor, push the red lock area with some force to connect it to the sensor. Check the condition of the sensor afterward.
7. If needed, remove the old sensor and insert a new one after unplugging the red wire harness plug. Sometimes, the Tesla Model 3 Park Assist not working issue arises due to the faulty sensor.
8. Finally, put everything back in place by reversing the process.

By following these steps, you can fix the issue of a disconnected or faulty front ultrasonic sensor that is causing the Park Assist to become unavailable.
