Hi! I see you're encountering error code 1000 with the USAA DriveSafe app on your iPhone. I'd like to help you get that sorted out. To start, could you tell me if you see this error right when you open the app, or does it appear during a certain action, like starting a trip or logging in?

While you let me know, a common cause for error 1000 can be related to app permissions, especially location and sensor access, since DriveSafe uses your phone's sensors and location to track driving behavior.

Here’s a step-by-step you can try on your iPhone with iOS 18.6.2:

1. Check App Permissions:
- Open your iPhone Settings.
- Scroll down and tap DriveSafe.
- Make sure Location is set to “While Using the App” or “Always.”
- Also, verify permissions for motion & fitness sensors if available.
- Ensure Background App Refresh is enabled so DriveSafe can run properly.

2. Close and Reopen the App:
- Swipe up from the bottom and hold to access the app switcher.
- Find the DriveSafe app and swipe it up to force close it.
- Restart the app and see if it still shows error 1000.

3. Restart Your iPhone:
- Press and hold the side button and volume up or down button until the slider appears.
- Slide to power off, wait a moment, then turn your phone back on.

4. Update the App:
- Open the App Store.
- Tap your profile icon at the top right.
- Scroll and check if there’s an update for DriveSafe; if yes, update it.

If you’ve already done some of these steps, please let me know which ones, and any other details like if the phone is connected to Wi-Fi or cellular data when this happens. We can then explore more advanced troubleshooting.

Are you able to try the permissions check and let me know what you find?
