2016 Traverse LS
I’ve had this vehicle for 2 weeks. I paired my iPhone with the vehicle, but it didn’t sync my contacts, so I have to say the phone number.
Also, there isn’t a phone icon on my screen. Are all 2016’s missing that?

 

Ugh, missing contacts can be a real pain! Let's see what we can do.
First, check your iCloud settings. Make sure Contacts is turned on. You can do this by going to Settings > [Your Name] > iCloud.
If that doesn't work, try restarting your iPhone. Sometimes, a simple restart can fix weird glitches.
As a last resort, you might have to restore your iPhone from a backup. But before you do that, make sure you have a recent backup.
