Tesla Lane Assist Not Working

The Lane Assist feature in the Tesla helps drivers detect when the car is steering out of the lane and also informs them of the presence of any vehicle beside them. If you face any issue with the Lane Assist features, there are multiple reasons behind such issues. I am going to discuss some of them and the tips and solutions to effortlessly address this issue.

Dirty Sensors

When you experience a Lane Assist issue, the first thing to ensure is whether the camera or sensors are clean and free of any obstruction. The Lane Assist feature works by using the sensors to determine when the vehicle is steering outside of the driving lane. Therefore, if sensors are damaged or not cleaned, they will not work properly.

What To Do?

So, if such things happen to you, what can you do? Follow the following instructions to clean your camera and sensors:

First, locate all the cameras in your car; you can find two in the B pillar, three in the rearview mirror, one under the trunk lid, and two in the badge turn signal assembly. Additionally, keep in mind the number of cameras might vary depending on the car model you own.
Next, take any spray bottle and apply the solution directly onto the lenses of each. Be careful and gentle with your actions so as to not damage anything.
After cleaning the camera, find the sensors and gently clean them with a pressure washer. After cleaning them with water, dry them using a rag (avoid rough clothes).

Technical Fault

Sometimes, it happens that Tesla undergoes issues with the software or hardware. This happens due to different factors, including bugs in the software, malfunctioning in the hardware components, as well as compatibility issues between different system components. The fault in Tesla’s internal system can affect the overall functionality of the car.

Therefore, it is necessary to address such issues to ensure the proper and reliable functioning of driver assistance features. To solve this problem, you can follow the following troubleshooting solution below, which will only take a few minutes.

What To Do?

First, press and hold both scroll buttons located on the steering wheel for a few seconds until the screen turns completely black (power off).
Wait a few seconds for the screen to activate. This is the easiest and simplest reboot option, if this does not work, then you can carry out the following reboot process:
Navigate to the “Control” option and then press the “Safety” option.
Lastly, click the “Power Off” button once again.
Afterward, step out of your car and open the front trunk.
Next, take out the top panel storage to access the battery compartment.
Now, carefully unplug the high-voltage loop and disconnect the ground wire from the 12V battery.
At least wait for about five minutes before plugging the high-voltage loop back in and reconnecting the ground wire.
Put back the top panel and close the hood.
Stand outside for a few minutes before getting into your car.
Lastly, press the brake pedal to check whether the problem is resolved.

Outdated System

Another reason could be that your car’s system is outdated and you haven’t upgraded it yet. Upgrading the software is necessary to keep the Tesla system running smoothly.

What To Do?

Open your Tesla app and navigate to the “Software Update” option to check whether you have any pending installation.
If you have an update notification, click on the “install” option to begin the installation process.
I will advise that you update the software when you are not using it and leave it to reboot overnight on its own.

Furthermore, before carrying out these above-mentioned solutions, ensure that you have turned on the lane assist feature. Additionally, weather or environmental conditions, including rain or faded lane markings, can also affect the Autopilot performance.

Ending Lines

To sum up, Tesla Lane Assist might not be working due to the outdated system, technical errors, etc. Follow the instructions provided in this guide to resolve your problem successfully. However, if you continue to face the same problem, you can consult the Tesla service.
