Reboot instructions for your Tesla

Last updated 15-Oct-2021

Tesla cars can sometimes find themselves with a software gremlin that requires a reboot or reset. It's not that common, but it's certainly something that all owners need to be aware of as it solves the majority of issues. Which of the various computers in the car has had the issue means different resets may be needed, the most common one is a simple main screen reboot, but if the fault is deeper within the car, for instance linked to the autopilot or chargers, a bigger reset may be required. It's also possible that just leaving the car alone for a few hours will cure the problem as the car will go to sleep and effectively reboot itself when you wake it up.

The crashing of the main screen (MCU) also seems to be linked to one of a number of issues that point to a memory leak of some description. We provide some tips to help trouble shoot. This is less of a problem on later cars, but those MS and MX cars with the earlier MCU may be showing signs of an eMMC failure

The reboot options

The following reboot options exist. While some are possible while driving, we recommend that the car should always be stationary and in a safe place before rebooting the car.

Tesla now suggest unplugging all USB devices prior to performing a reboot as it can prevent some sub systems from shutting down.

Software updates

After a software update, we recommend an option 4 reboot, especially if any function doesn't see, to work correctly. Sometimes the problems are subtle such as the car not wanting to go to sleep causing excessive battery drain over night. If you experience any perculiar behaviour of the car, such a reboot should be the first thing to try as it tends to solve many niggles caused by the software failing.

Additional things to try

Some people report their car screens rebooting randomly, the first sign of this on an MS or MX is if the Air-bag light comes on. Nobody knows all the reasons, but there have been a number of software glitches over the years that can cause this to a greater or lesser extent. If you are experiencing frequent reboots, maybe the air-bag light appearing and the steps above do not help, then some or all of the following have been known to help.

They all point to a memory issue, possibly the eMMC issue below, or a software fault of one form or another. Either the memory cannot handle some form of corrupted data, or the actions below move the active part of the eMMC memory to a different area which has not started to fail. If one of the suggestions below does resolve the issue, you should still log the issue with Tesla especially if in warranty as it may be temporary. If out of warranty you may want to consider the eMMC resolution below. If you can attribute the issue to a specific rogue music file or contact then there is no need to contact Tesla.

None of the above options are ideal, the car should be able to handle problems, but if one of these temporarily cures the problem you can start to work out how to permanently fix. It may be a rogue MP3 file, or a phone contact with some corrupted details. If however its trip or destination data then it could point to a problem with the car memory.
