Buick massively dropped the ball on MFA. They make it terribly difficult to use, and there's no option to opt out of it. It defaulted to an email address that I don't have tied to my phone, and the phone number that they already have isn't a default option. I *did* get it to work, but their screens are terrible and you can't see any of the numbers that you are typing in. This visibility issue exists both for trying to register a phone number AND every single time you need to insert an MFA code.

This certainly isn't what we like to hear, Michelle. As a first step, we recommend uninstalling and reinstalling your app. If this doesn't offer a remedy, please send our team an email at socialmedia@gm.com with "ATTN: myBuick/michelle snyder" in the subject line so we can investigate further on our end. ~Jacob

1 year after you broke this terrible app, it's still a lousy user experience. It takes too long to open. Why do I have to hit confirm after face unlock? Just open already! Stop wasting my time with your cheap software. The silly video splash screen is distracting and a ridiculous waste of my bandwidth. You cannot send an address to the in-vehicle navigation, so now I'm stuck using the equally awful touch screen in my car and its maddening lag filled interface. Two massive thumbs down Buick.

For weeks the app hasn't been able to connect to the servers. When it did it would continuously fail to start my vehicle. After reading similar reviews I decided to delete and reinstall the app. Now it just freezes and eventually crashes. I cant even get to the sign in screen. Why am I paying for something thats doesn't work. (No I'm not about to send so email to GM for them to fix an app. This is why we write reviews in the first place. These dev responses should goto the company. Not the user)
