How to install an EV software update
You can install most owner-accessible updates from the vehicle’s software screen or connected phone app. The experience is much like updating a phone, except your car may be unavailable while the new software installs. Before starting, park somewhere secure, read every on-screen instruction, and make sure you won’t need to move the car until the process finishes.
- Confirm that the update is genuine. Open the vehicle’s built-in software menu or official manufacturer app rather than following a link from an unsolicited message.
- Read the update notice. Check whether the vehicle requires Wi-Fi, a particular battery level, external power, or another prerequisite specified by the manufacturer.
- Park in a safe location. Put the car in Park, close anything the instructions identify, and leave the vehicle where it can remain undisturbed.
- Connect to Wi-Fi if prompted. Some updates require a stable connection for downloading even if the car normally uses its own cellular connection.
- Schedule enough time. In Recharged’s experience, installation can take anywhere from 20 minutes to 2 hours, depending on the update.
- Start the installation and leave the car alone. Don’t attempt to drive, reboot the screen, disconnect power, or otherwise interrupt the process unless the manufacturer’s instructions specifically tell you to.
- Verify completion. Look for a success message, reopen the software screen, and read the release notes before driving.
Don’t start an update when you need the car
The update path depends on your EV
Your car determines whether you can install an update yourself or must book service. Recharged can run an available Tesla Model 3 update after connecting the car to Wi-Fi, while certain Volkswagen ID.4 updates have required a shop visit. Even among vehicles that support over-the-air updates, software delivered wirelessly, the method and prerequisites can change from one update to the next.
Update path comparison
Check the vehicle’s software screen, official app, and manufacturer instructions to identify the correct route.
| Update path | Where it starts | What you need | Main caution |
|---|---|---|---|
| In-car OTA | Vehicle screen | Wi-Fi if prompted | Car may be unavailable |
| App-scheduled OTA | Official phone app | Stable connection | Confirm car is parked |
| Service-installed | Authorized service location | Appointment | Allow extra time |
The same vehicle may use different paths for different software modules.
Don’t assume a car with wireless updates can update every system wirelessly. A manufacturer may send infotainment changes over the air but require service equipment for another module. If no installation button appears, the vehicle reports an error, or the notice tells you to seek service, stop troubleshooting by guesswork and follow the automaker’s service route.
We connect eligible vehicles to Wi-Fi so available updates can keep moving while the cars are with us. Before a scheduled pickup, we check again; if an update hasn’t installed, we either run it or show the buyer how to complete it at home.
What Recharged battery data can, and can’t, show
Software status does not prove battery health, which is why Recharged checks the two separately. Across 2,242 Recharged Score battery inspections, average tested remaining capacity was 93.9% of original capacity, and the median was 94.9%. Those are physical battery-diagnostic results, not conclusions drawn from the software version shown on the dashboard.
An update may change menus, charging controls, or the way information is displayed, but it doesn’t replace a capacity test. If you’re shopping for a used EV, review both the installed software and a verified EV battery-health report. The practical takeaway is simple: being fully updated is useful, but measured battery condition tells you far more about the pack itself.

What to check after installation
Confirm that the update succeeded before you drive away. Open the software menu, verify that no failure message remains, and read the release notes so you know whether familiar controls have moved or changed. Tesla, for example, provides release notes from its software screen, but the exact location varies by manufacturer.
Post-update check
Read the release notes
Review new features, changed controls, fixes, and any follow-up action requested by the manufacturer.
Check your settings
Confirm your charge limit, scheduled charging, driver profile, climate schedule, and assistance preferences still match your choices.
Look for warnings
Don’t dismiss a persistent error or safety-system alert as a harmless update quirk; follow the vehicle’s instructions.
Test before a long trip
Take a short local drive and verify navigation, charging information, cameras, and frequently used controls before traveling.
This is also a good moment to review your broader ownership setup. If you’ve recently bought the car, work through a used-EV buying checklist and make sure the vehicle has been removed from the former owner’s account. For reliable downloading and scheduled charging at home, compare the update instructions with your home EV charging setup rather than assuming the car needs to remain plugged in.

EV software update FAQ
The bottom line
Install an EV update only through the vehicle’s official screen, app, or authorized service channel. Give the process enough time, use Wi-Fi when requested, and don’t interrupt the car once installation starts. When buying used, check the software version, but pair that check with verified battery diagnostics and the rest of the vehicle inspection, because fresh software alone doesn’t tell you how healthy the EV is.
