Tesla vehicles are known for their cutting-edge technology and seamless performance. However, just like any other electronic device, there may be instances when your Tesla won’t turn on or experience malfunctions. In this comprehensive troubleshooting guide, we will explore the possible reasons behind this issue and provide step-by-step solutions to get your Tesla back up and running.
Tesla Won’t Start: Understanding the Problem
When faced with a Tesla that won’t turn on, it’s essential to diagnose the problem accurately. While there can be various causes, such as internal bugs, software updates, or loose connections, it’s crucial to identify the specific issue before proceeding with the troubleshooting steps. Let’s dive into the potential reasons why your Tesla may not be powered on.

Delayed Software Update
In some cases, delaying software updates can lead to a temporary screen blackout or unusual behavior in your Tesla. The system may require a reboot to resolve the issue and ensure smooth operation.
Internal System Bugs
Tesla vehicles are equipped with advanced internal systems that can occasionally encounter bugs or overload. These issues may prevent the touchscreen from turning on while other functionalities, such as the steering wheel and brakes, continue to work.
Loose Touchscreen Plug
Another possible cause for a non-responsive touchscreen is a loosely inserted plug that connects the touchscreen to the vehicle. When this plug becomes dislodged, the screen may fail to power on despite other components functioning correctly.
Tesla Won’t Start: Soft Rebooting Options
Before resorting to more drastic measures, it’s advisable to attempt a soft reboot to restart the software and resolve minor glitches. Tesla offers two tiers of soft reboot options: the touchscreen reset and the full vehicle reset.

Touchscreen Reset
To perform a touchscreen reset, press and hold both scroll wheels on either side of the steering wheel for up to 10 seconds. This action will initiate a reboot of the main/central screen. It’s important to note that while this can be done while driving, it’s recommended to perform this reset when the vehicle is stationary.
Full Vehicle Reset
If the issue persists after a touchscreen reset, a full vehicle reset may be necessary. To execute a full vehicle reset, go to the main screen, access the service menu, and select “Power Off.” Allow the system to shut down completely by waiting until the screens turn off and the interior light goes out. After a few minutes, press the brake pedal to awaken the car and initiate the restart.
Tesla Won’t Start: Hard Rebooting Options
If the soft reboot options fail to resolve the issue, a hard reboot may be required. However, it’s essential to exercise caution as this method involves disconnecting the 12V battery.
Factory Hard Reset
A factory hard reset should only be attempted as a last resort or under the guidance of Tesla support. This process is similar to a full power down and restart, but it involves selecting the factory reset option on the screen. It’s important to note that performing a factory hard reset erases all personal settings and data, so it should be used sparingly.
Tesla Won’t Start: Additional Troubleshooting Tips
Update Software
Ensuring that your Tesla is running the latest software version is crucial for optimal performance. Regularly check for software updates and install them promptly to prevent potential issues.
Check USB Connections
If you have any USB devices connected to your Tesla, such as a dashcam or music storage device, disconnect them and observe if the issue persists. Faulty or incompatible USB devices can sometimes interfere with the proper functioning of the vehicle’s systems.
Clear Trip Computers and Previous Destinations
Clearing the trip computers and deleting previous destinations from your Tesla’s navigation system can help improve system stability. These actions reduce the load on the memory and can potentially resolve issues related to excessive data storage.
Disconnect Bluetooth Devices
If you have a Bluetooth device connected to your Tesla, such as a phone with a large number of contacts, try disconnecting it temporarily. Large amounts of data from Bluetooth devices can sometimes overwhelm the system and cause malfunctions.
Recognizing Signs of eMMC Failure
In rare cases, a Tesla’s failure to turn on may be due to an eMMC (embedded Multi-Media Card) failure. This issue primarily affects older Tesla models with the MCU1 (Media Control Unit 1) system. Signs of eMMC failure include frequent reboots, the appearance of the airbag light, or persistent screen freezes. If you suspect eMMC failure, it’s essential to contact Tesla support for further assistance.
Tesla Won’t Start: Conclusion
Experiencing a Tesla that won’t turn on can be frustrating, but with the right troubleshooting steps, you can resolve the issue and get back on the road. Start with a soft reboot, such as a touchscreen or full vehicle reset, and follow the additional troubleshooting tips provided. If all else fails, reach out to Tesla support for further guidance. By staying informed and proactive, you can ensure that your Tesla continues to deliver the exceptional driving experience it’s renowned for.
