I seem to be having a bigger issue than most here. It's not that my iPhone 11 Pro Max running iOS 13.1.2 doesn't work when connected to my 2013 Dodge Dart, it won't reconnect between sessions and most of the time won't even be discovered by the car.
I have started from scratch with the car several times by deleting all Bluetooth devices and re-pairing. Typically when I start he pairing process on the car's Uconnect system, it never even shows up on my phone. I was able to get to show up once after trying the "turn bluetooth off, hard reset iPhone, turn bluetooth back on" trick. After that pairing was complete, the phone was able to play back audio but it was choppy and speeding up and slowing down randomly. When I turned the car off and back on, while Uconnect remained as an available device on the phone and the phone remained in the car's system, the car reported that the phone was out of range when I tried to connect them despite being inches from the radio.
After this, I deleted the phone from the car and the car from the phone and tried the same hard reset trick to re-pair it. It didn't work. I decided to try to pair an old iPad I have running iOS 12 and guess what — it worked perfectly. Also, after pairing the iPad, the iPhone once again showed up when I started the pairing process. It worked better this time but yet again, turning the car off and back on made them unable to find each other.
Since the iPad worked fine, I have to believe it's iOS 13-related. Oddly, the issue is limited to my 2013 Dodge Dart with the Uconnect system. My 2015 Mazda CX-5 works flawlessly with the iPhone 11 Pro Max.
