Hi! I see you're encountering Error 100 when trying to log in or reset your password on the MyMazda app. Let’s get this sorted together.

First, can you confirm if you’ve already tried resetting your password through the app’s "Forgot Password" option, and did you receive the password reset email? Also, have you attempted logging in via the MyMazda website to see if the issue is app-specific or account-related?

While I wait for your confirmation, here’s a step-by-step guide that often helps with Error 100 login issues:

1. Check Internet Connection: Ensure your iPhone is connected to a stable Wi-Fi or cellular network.

2. Update the App: Go to the App Store and verify that the MyMazda app is updated to the latest version.

3. Restart Your iPhone: A simple restart can sometimes clear temporary glitches.

4. Clear App Cache / Reinstall: Delete the MyMazda app completely, then reinstall it fresh from the App Store.

5. Password Reset via Website: Instead of the app, go to the MyMazda website, use the password reset option there, and follow the instructions. Sometimes the app may have server sync issues causing Error 100.

6. Check for Service Outages: Occasionally, Mazda’s connected services or servers may be down. If you can, check online forums or Mazda’s official channels to see if others report similar issues.

7. Contact Support: If none of the above helps, it's best to contact Mazda support directly via email at [email protected] for assistance tailored to your account and app instance.

If you’ve done some of these already, please let me know which, and if any error codes or messages appear besides Error 100. That way, I can dive deeper or suggest advanced troubleshooting steps.

Does this align with what you’ve tried so far? And do you have access to your registered email for password reset links?
