Hi there! I understand you're seeing an "error retrieving vehicle details" message in the Bristol West Insurance app. Let's get that sorted out for you.

To start, could you tell me a bit more about when this error happens? For example:
- Are you trying to add a new vehicle or view details of an already added vehicle?
- Does the error occur every time you try or just occasionally?
- Have you tried any steps so far like restarting the app or your device?

Meanwhile, here are some basic steps that often help resolve this kind of issue on your Windows device with the WebKit browser:

1. Refresh the App or Browser: Close and reopen the Bristol West app or browser tab to clear temporary glitches.
2. Check Internet Connection: Ensure your device has a stable internet connection, as the app needs to fetch vehicle data online.
3. Clear Cache and Cookies (for browser users): Since you’re using WebKit on Windows, clearing your browser’s cache may resolve corrupted data issues.
4. Update the App: Ensure your Bristol West app is updated to the latest version if you are using the app rather than a browser.
5. Sign Out and Sign Back In: Logging out and back in can refresh your session and sometimes fix data retrieval issues.

Please try these and let me know if the problem persists. If it does, I can guide you through some advanced steps or help get you in touch with Bristol West technical support directly.

Are you okay with trying these steps now?
