National Rental Car App not working on iPhone 14 Pro Max

At least I know I am not the only one experiencing this problem. It was working perfectly until a few months ago. I thought it may be something with the iPhone 14. Maybe more to do with the updates to the iOS. Thank you!

Hello CRIII,

Thanks for choosing the Apple Support Communities. We see you're unable to open a third party app. When this happens as you have tried, we have a few steps to potentially resolve the issue that you haven't tried.

If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

"Close and reopen the app

Force the app to close. Then open the app to see if it works as expected.

Restart your device

Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.

Check for updates

To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.

Delete the app, then redownload it

Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed."

We hope this helps.

Cheers!

Hey CRIII,

Thanks for trying those steps. Since the issue is only occurring with the National Rental Car app, we recommend reaching out to the developer at this point, since they are the experts in their app. You can use these steps to contact them: How to contact an app developer - Apple Support

Take care.

I’m having the same issue on a 12 Pro with iOS 16.3.1, though I believe the issue started with the previous iOS version. The National app worked perfectly - used it all the time. Was actually on a trip when it quit working and had to start calling National customer service. Reached out to their IT team but they had no idea what the issue was. All they could tell me was their servers were up and working.

Same here. I just updated to 16.4 and it still doesn’t work. The IT help desk at National gave the exact answer. “Well it is working on our end”. End of discussion! Maybe it will be resolved one day. I’m not holding my breath. Until then I’ll just have to use the web version on my computer or my iPad.

Same issue on my IPhone 12… deleted and restarted many times but app crashes as you load it. Quite frustrating as i use whenever I travel :(

While admittedly not terribly helpful …

… the National App (Ver 5.2.1) does seem to be running normally for me. (iPhone 14 ProMax / iOS 16.4).

Sorry for your difficulties.
