Chevrolet Over-the-Air Software Updates Explained: Keep Your Chevy Current Without Leaving Home
You know that satisfying feeling when your phone updates overnight and suddenly works better the next morning? Imagine that same magic happening to your Chevrolet without you ever having to visit a dealership.
That’s exactly what Over-the-Air (OTA) software updates do for your Chevy. Instead of scheduling service appointments and waiting around, your vehicle can download and install the latest software right from your driveway. Let’s break down how this works, why it matters, and the one rule you absolutely cannot ignore.
TL;DR
Over-the-Air (OTA) updates let your Chevrolet download software improvements, new features, and bug fixes wirelessly. The update process happens in two steps — automatic download (you can still drive) followed by installation (the vehicle is parked and off for about 20 minutes). Your vehicle needs an active data connection or Wi-Fi. Critical warning: You must install updates within 45 days of receiving them, or warranty coverage for related damage may be denied . Many models now offer this feature, including the Trax, Blazer, Silverado EV, and 2026 Corvette .
Key Takeaways
- Two-step process — downloads happen automatically in the background; installation requires parking and turning off the vehicle
- Installation takes about 20 minutes — you can’t drive the vehicle during this time
- Connectivity is required — the system uses the vehicle’s 4G LTE connection or your Wi-Fi
- 45-day rule — install updates within 45 days or risk losing warranty coverage on related issues
- Available on many models — including Trax, Blazer, Equinox, Silverado, and Corvette
- Dealers can also perform updates if you prefer professional help
How Over-the-Air Updates Actually Work
The process is designed to be as painless as possible. There are two stages, and you only really need to pay attention during the second one.
Step 1: Download (The Easy Part)
Your Chevy automatically downloads software updates in the background. You can drive normally during this stage — the download pauses if you turn off the vehicle or lose connectivity and resumes when conditions are right .
Download times vary based on the update size and your wireless signal strength . The system works over your vehicle’s built-in 4G LTE connection or a secure Wi-Fi network like your home hotspot or mobile device hotspot . But here’s a helpful tip — avoid parking in a garage or covered space during downloads if possible, because it can block the signal .
Step 2: Installation (The Important Part)
Once the download is complete, you’ll get a notification on your center display when you next shift into Park . This is where you need to make time.
When you’re ready, tap “install” and follow the prompts — the vehicle will need to be turned off, parked, and you won’t be able to drive it during the installation . The entire process takes about 20 minutes or less .
Important: Installation can’t be stopped once it starts, so make sure you’re parked in a safe spot before beginning . The center display may stay on during the installation, and it’s completely normal for the system to reset a few times .
The 45-Day Rule: Don’t Procrastinate on This
Here’s where things get serious. GM has a policy that affects 2025 and 2026 model year vehicles: you must install Over-the-Air updates within 45 days of the update becoming available to your vehicle .
If you don’t, any damage resulting from the outdated software will not be covered by your warranty . That’s not a small thing — it could mean paying thousands of dollars out of pocket for problems that a simple update would have prevented.
On the flip side, if an OTA update causes damage to your vehicle, GM will cover that repair under warranty . So there’s no reason to wait — install updates as soon as you get the notification.
“The 45-day window encourages timely updates, so customers can consistently enjoy an optimal vehicle experience, while reducing the risk of potentially avoidable issues.” — GM Statement

How to Manually Check for Updates
If you don’t want to wait for a notification, you can check manually:
- Go to the Settings app on the infotainment home screen
- Select the System tab
- Navigate to the Vehicle Software section
- Touch Updates and follow the on-screen prompts
The exact steps may vary slightly by vehicle, but the general path is the same across models .
What If Something Goes Wrong?
Most software update issues resolve themselves. If you see a download or connection error, it might simply mean your vehicle has limited cellular connectivity. Moving to an area with better signal usually fixes the problem .
If the update option appears greyed out, the vehicle conditions might not be right. Try driving the vehicle around to improve battery condition, or charge the battery if you have an EV .
For persistent problems, contact your Chevrolet dealer. They can perform updates for you if needed — and they’ll handle any troubleshooting .
