MyChevrolet App Not Working | Most Effective Fix

If your myChevrolet app is not working, you are not alone. Many users have reported issues recently (November 2025) with the app failing to sign in, crashing on the “PIN” screen, or not updating vehicle status.

Here is a step-by-step guide to fixing it, ordered from the easiest solution to the “hard reset” for your car.

1. The “Clean Install” Fix (Most Effective for App Bugs)

If the app freezes, won’t let you sign in, or gets stuck on the Terms/PIN screen, a simple reinstall often isn’t enough. You must clear the data first.

• For Android:

  1. Go to Settings > Apps > myChevrolet.

  2. Tap Storage & Cache.

  3. Tap Clear Storage (or Clear Data) AND Clear Cache.

  4. Uninstall the app.

  5. Restart your phone.

  6. Reinstall the app from the Google Play Store and log in.

• For iPhone (iOS):

  1. Go to Settings > General > iPhone Storage.

  2. Find myChevrolet.

  3. Tap Delete App (Don’t just remove it from the home screen; delete it entirely here to remove the data).

  4. Restart your iPhone.

  5. Reinstall from the App Store.

2. The “Vehicle Power Cycle” (If Remote Commands/Status Fail)

If the app opens but remote start won’t work or the tire pressure/fuel status isn’t updating, the issue is likely the car’s communication module, not your phone. The car needs a “reboot” to reconnect to the OnStar network.

Follow these steps exactly:

1. Start the car and let it run for about 60 seconds in an open area (to get a cell signal).

2. Turn the car off.

3. Open the driver’s door and exit the vehicle.

4. Close the door and Lock the car using your key fob.

5. Walk away (at least 15-20 feet) with the key fob.

6. WAIT for 2 to 5 minutes.

   • Why? You need to wait for the car’s computer to go into “sleep mode.” Watch the red/blue light on the dashboard (if you have one) or the OnStar light; wait until all dash lights are fully off.

7. Try the app again. The status should now update.

3. Check for the “Terms & Conditions” Trap

Sometimes the app stops working because GM updated their Terms of Service, and you haven’t accepted them yet.

1. Log in to the Chevrolet Owner Center website on a computer or mobile browser (Chrome/Safari).

2. If a pop-up appears asking you to accept new terms, click Accept.

3. Open the app again; it should now let you in.

4. Still not working?

If none of the above works, the OnStar server might be down or your account link may be broken.

• Test OnStar: Press the blue OnStar button in your car. If it doesn’t connect to an advisor, your car’s hardware (antenna/module) might need service.

• Call Support: Dial 1-877-558-8352 (OnStar/Chevy Support). Tell them you have already tried “uninstalling” and “power cycling” the vehicle so they don’t make you do it again.
