Tesla Software Update Stuck? What to Check First

For a stuck download, check the car's Wi-Fi connection. For an installation already in progress, keep the car parked and check the elapsed time and completion status before restarting anything. A stationary percentage alone does not identify the fault.
This guide uses Tesla Support and Model 3 owner instructions checked October 17, 2026. Use the owner's manual on your own touchscreen for your model and software; menus and features can differ.
Find Your Update Stage First
| What the screen shows | What to check next |
|---|---|
| Downloading, including a rate of 0 B/s | Wi-Fi and download checks. Record whether the car itself is connected. |
| A percentage such as 50%, 60% or 100% that is not changing | Read the accompanying status text: a percentage does not distinguish downloading from installing. |
| Download complete, clock icon or scheduled time | Installation prerequisites. A completed download may still be waiting for installation. |
| Installing | Elapsed time and Tesla's restart condition. Keep the vehicle parked. |
| Failure message, or no update offered | Failed update versus rollout availability. These require different next steps. |
The download, clock and installation distinctions come from Tesla's Model 3 update instructions. The example percentages are symptoms to record, not diagnostic codes.
Record the Status Before Changing Anything
Before changing settings, note the software version, exact status text, any alert code, and when you first noticed the problem. Take a screenshot of the app or a photo of the touchscreen while safely parked. Distinguish the time you noticed a stalled percentage from the time installation actually began.
Keep a short log: for example, “Download at 50% at 18:10; same at 18:40; connected to home Wi-Fi.” This is more useful for a service request than “update broken.” Do not diagnose a damaged computer or buy networking equipment from a percentage alone.
Download Stuck at 0 B/s or a Fixed Percentage
Tesla recommends stable Wi-Fi with at least three signal bars. Move closer to the source only before installation begins. Tesla's software update support guidance.
Use this sequence while parked and still in the download stage:
- Check the network name and connection on the touchscreen. A phone connected nearby does not prove the car is online.
- Open Wi-Fi > Diagnostics, if available, and record any connection warning. Tesla also places a diagnostics link beneath the update progress bar on supported software.
- If connection fails, forget and reconnect to the network, with its password available. A public network requiring a browser sign-in page is unsuitable for the documented Model 3 Wi-Fi connection.
- Compare another reliable network. A phone hotspot is an option, subject to your mobile data allowance and carrier restrictions. Keep the car parked for this check.
- Record whether transfer resumes and whether the result changes between networks. Persistent lack of progress needs Tesla Service review.
These network options are documented in Tesla's Wi-Fi diagnostics and troubleshooting. A result that improves on another network points toward investigating the original connection; it does not prove that the vehicle hardware is fault-free.
What does 0 B/s mean? It tells you that the displayed download rate is zero at that moment. It does not identify a failed computer, prove corrupted software or establish that another reboot will help. Likewise, the cited instructions provide no repair specific to 50%, 60% or 100%. Follow the stage and status text rather than a percentage-based reset recipe.
Download Finished, but Installation Has Not Started
On Model 3, use the clock icon to install or schedule while parked. Keep Climate On, Pet Mode and Camp Mode prevent installation. Plan the update when nobody depends on those features, and follow any battery or other prerequisites shown by your vehicle.
Check whether a scheduled time is still in the future. If the car was being driven at the scheduled time, the Model 3 manual says to schedule again. Do not switch off a protective climate setting while a person or animal relies on it just to begin an update.
There is no need to disconnect charging simply to install: charging pauses during installation and resumes afterward. The Model 3 software update instructions explain these conditions.
Installation Is Running: When Is a Restart Appropriate?
Do not attempt to drive or use the vehicle during installation. Some functions, including safety systems and door or window operation, may be limited. Allow time beyond a typical estimate; duration alone is not proof of failure. See Tesla’s Model 3 installation restrictions.
If more than three hours have passed since the update started and the app has no completion notification, Tesla recommends a touchscreen restart. If unsuccessful, schedule service. Use that documented condition instead of restarting immediately when progress pauses. Tesla's stalled-update troubleshooting provides the escalation point.
Keep the start time, last observed progress and any app notification together. The three-hour condition is an escalation check, not a promise that every installation finishes within three hours. An active installation cannot be canceled through the ordinary update controls. Do not turn a paused percentage into a reason to disconnect vehicle power or attempt an undocumented reinstall.
For a Model 3 touchscreen restart, stop and select Park, hold both steering-wheel scroll buttons until the screen goes black, then wait approximately 30 seconds. The display, warnings and rear camera are unavailable while it restarts. This restarts the touchscreen only; it does not power-cycle the vehicle. Follow Tesla's Model 3 restart procedure and check your own manual for other models.
Update Failed, or No New Update Is Available
An absent update is a different situation from a frozen installation. Rollouts vary, and selecting Advanced is a preference, not a guaranteed delivery date. Tesla does not send the latest version on individual request. Tesla Support explains availability.
The Model 3 manual advises awaiting the next update after a failed installation; rollback is unavailable. Persistent unresponsiveness belongs with Tesla Service. Include your status log, screenshots and checks already attempted. After successful installation, review the release notes before using changed features. See the Model 3 manual.
Distinguish an installation-failed notice on an otherwise responsive vehicle from a car that remains unresponsive or cannot be used normally. The latter needs direct assistance; do not treat the next-update advice as permission to ignore an active fault. Follow vehicle warnings and contact Tesla Roadside Assistance if the car is immobilized or unsafe to use.
What to Send Tesla Service
A concise record helps a technician separate a network problem from an installation failure:
- Model/build and installed software version; offered version if shown.
- Exact stage, status message or alert, with a screenshot.
- Time the update actually started and the most recent progress you observed.
- Whether the app reported completion and whether the touchscreen responds.
- For a download problem: signal strength, diagnostic message and whether another network changed the result.
- Any restart already attempted and its result.
For example, report “Downloading, 0 B/s; car connected to home Wi-Fi; no change on a second network” rather than “stuck at 60%.” The record does not need passwords or Wi-Fi credentials.
After the Update Completes
Confirm the installed version and read the release notes. If charging had paused, check that it has resumed. A successful update does not prove that every separate symptom has been fixed.
If the update has completed but USB recording still fails, use the USB recognition and Dashcam checks. For a touchscreen that remains frozen, use the screen-restart guide with the vehicle stopped and in Park. Keep these post-update symptoms separate from an installation that is still running.
