I took my car (Sept 2016 build) to the dealer asking to get updated. I had the following issues listed -
1. Static on phone calls.
2. CarPlay slow to reconnect when getting back into car after a short stop (like stopping at an ATM).
3. CarPlay unresponsive at times, moving iDrive controller causes no action on the CarPlay screen.
I have an iPhone 7 on iOS 10.3.1 and mentioned that these issues have been happening regardless of iOS level.
The dealer said that they tried a couple different iPhones and couldn't replicate the issues
Suffice it to say, this dealership won't be servicing my car anymore. Instead of simply updating the software as I requested, they tried a few phones and declared it good, basically saying that there is no issue and that it's either me or my device. Not sure why some dealerships haven't a clue when it comes to good customer service
I'll try again in a few weeks at a different dealership and report back when I do.
