Iphone 14 pro Bluetooth not finding vehicle

I thought the problem was with my Car, and I even argued with Nissan, now I learned it's my iPhone 14.

My iPhone 14 will not recognize my 2019 Nissan Leaf 3/4 of the time. However, the iPhone SE that my husband has, will recognize it EVERY time, even if he is in a different car behind me!

Both our phones are set up the same and have "carAccessory" in the my Devices. I actually have to restart the car to get the iPhone 14 to recognize it, which led me to initially believe it was the car. But since we have two different iPhones, I now know better. Does anyone have any way to fix this? I asked Apple and they blamed Nissan, which is where I got into an argument with Nissan. Thanks in advance
