4 Reasons Why Tesla Cruise Control Unavailable
Table Of Content
Tesla vehicles have a more advanced version of cruise control called Autopilot, which can also automatically steer, brake, and change lanes. “Sentry Mode” uses your vehicle’s cameras to detect suspicious activity and prevent theft or vandalism. If a threat is perceived, your car will start flashing its headlights, sounding its alarm, and recording the area around it.

Check the front camera for obstruction and clear
If a firmware bug causes the issue, Tesla will likely release a software update to fix the problem. If a camera or sensor is obstructed, clean the cameras and sensors to remove any dirt, snow, ice, or mud that may be blocking them. Cruise control is a feature that allows the driver to set a desired speed and maintain it without pressing the accelerator pedal. Tesla’s cruise control, also known as Traffic-Aware Cruise Control, detects vehicles in front of the same lane. This feature reduces the Tesla’s speed to sustain a time-based distance from the vehicle in front to the selected speed.

Reasons Behind the Tesla Cruise Control Unavailable and Their Solutions
When you engage TACC, your Tesla will automatically accelerate and decelerate based on the speed of the vehicle in front of you. If the vehicle in front of you speeds up, your Tesla will accelerate to match its speed, up to your set speed limit. If the front radar has no or low visibility due to temporary obstruction, clean the front radar to remove any dirt, snow, ice, or mud that may be blocking it. If the traction control setting is manually disabled or is repeatedly engaged to prevent wheels from slipping, enable the traction control setting.
Check your Tesla vehicle is updated with the latest software
While only speculatory, our experience shows us that some of the common malfunctions within a Tesla are software updates. Follow the step-by-step troubleshooting steps below to fix the Tesla cruise control unavailability issue. When the front radar is working correctly, it provides the necessary information for the Traffic-Aware Cruise Control and Autosteer features to operate. These features allow the car to maintain a safe distance from the vehicle in front and keep the car centered in its lane. Tesla’s cruise control system relies on sensors and radars to detect the car’s surroundings.
This can be done by physically examining each camera, looking for any signs of wear, looseness or damage. After about 30 seconds, the system will restart and the ECU, featured and cameras should all show a green signal. If any of the cameras show a red signal, then there’s an issue with that particular camera. If you notice any signs of damage, such as cracked lenses or broken connectors, then the camera needs to be replaced to restore the cruise control function.
Reduced front radar or camera visibility
On rarer occasions, the problem persists, and although you can drive your Tesla safely without Cruise Control, you may have to find out what’s wrong to get it fixed. You can still use the feature if a vehicle is ahead of you, but there must be at least 3 feet between both vehicles. You will most likely get an update alert on your Tesla account on your phone or your Tesla screen. Also, there may be condensation within the camera, in which case you cannot physically clean it. It will involve physically cleaning the particles and debris on the surface of the front camera.
Your Tesla uses cameras and GPS to detect road lines and other objects on the road. However, if the front radar is not functioning correctly, the cruise control system may become unavailable. In such cases, the radar and camera may not be able to detect the surroundings accurately, leading to the “Cruise Control Unavailable” message.

Obstruction of Cameras or Sensors
It’s essential to keep your Tesla updated with the latest software version as it may fix bugs causing problems with features like cruise control and Autosteer. Tesla regularly releases software updates to improve the performance and functionality of their vehicles. These updates can include bug fixes, new features, and improvements to existing features. In some cases, dirt, debris, or condensation can block the camera’s view, causing the system to lose its ability to function properly.

It is possible that prolonged driving has caused debris, mud, snow and other contaminants to cover the surface of the radar. But there are times when the feature may not restore itself without manual configurations. To check for updates, go to the Software tab on your touchscreen and tap “Check for Updates”.
Tesla cruise control is a system that can adjust the vehicle’s speed based on traffic and road conditions. Depending on the model, the system can be enabled by pressing or pulling down a stalk on the steering wheel column. Your vehicle may sense that the cameras need to be recalibrated to meet the safety requirements of the driver’s assistance system.
A great place to start would be understanding “How Tesla Cars Work” or examining whether “Tesla is considered a Tech Company“. These posts will give you a comprehensive view of how Tesla’s electric vehicles function from a technological standpoint. This process requires the car to be driven for 20 to 25 miles, preferably along roads with clear markings. It’s important to always keep your Tesla updated with the latest version of the software. To troubleshoot your issue with Tesla Cruise Control being unavailable, try the following checklist of nine possible fixes.
The Tesla owner’s manual has specific instructions on properly cleaning your vehicle’s camera lens. While “Sentry Mode” is a great feature, it uses a lot of battery power since it stays powered on even when the car is not in use. Having “Sentry Mode” on may cause your vehicle to lose the features of the Autopilot package, like cruise control until it’s turned off. It’s always a good idea to keep your vehicle software current by installing updates as soon as possible. If you don’t install updates when they become available, some features may become unavailable. However, your screen may sometimes indicate that the cruise control is unavailable.
When dealing with a case of Tesla cruise control unavailable, there are several solutions you can pursue. If your car runs on an older software version, it may be possible to experience challenges using some of its features. If there is a car, the camera visibility is unclear, and the car cannot judge whether a car is ahead; the cruise control will not engage.
What was happening was that as soon as I tried to enable even just TACC, my car would throw up an error message saying "Cruise Control Unavailable" with a link to "Read more". The small steering wheel icon that indicates "Autosteer is available" would also never come up. If this radar becomes obstructed or its visibility is reduced, the cruise control may become unavailable. If you exceed the maximum cruising speed set by your vehicle, the cruise control will disengage.
Depending on what service you need and where you are located, the app will show you available dates and times. To remove built-up debris or dirt, spraying water on the camera lens using a spray bottle is recommended. Wiping the lens with your hands, cloth, or any chemical cleaner is not recommended. Moreover, these maintenance checks provide sustainable solutions and ensure smooth driving experiences at all times. A common reason for Cruise Control to be unavailable is obstruction of the front radar sensor.
If any of the vehicle’s cameras or sensors become obstructed, the cruise control may become unavailable. When there are no obstacles in front of the car, Traffic-Aware Cruise Control will maintain a fixed driving speed. If the car detects another vehicle, it will automatically slow down to maintain a selected time-based distance from the car in front, up to the set speed. While it is inconvenient to not be able to use the autopilot features of your Tesla, there are several solutions to this problem, and it is still safe to drive in the meantime. For example, if an update didn’t go through on your Tesla correctly, reinstalling it could solve the problem.
