Music volumen down bluetooth after iOS 17.2

I am detecting problems with the volume level with the Bluetooth connection after the iOS 17.2 update. Before this problem persisted on the iPhone 11 and the iPhone 15 Pro, after the 17.2 update it seems that the problem was fixed on the iPhone 11 but still It persists on the iPhone 15 Pro. I have never had problems with the volume level in my car, but something Apple has changed that continues to affect it. How can it be corrected? Thank you very much for your support. I did a test with the same song and the same volume level (maximum volume on the smartphone and volume 12 on my Suzuki Swift) and these were the decibels results obtained. The Iphone 11 and 15 Pro has updated to iOS 17.2
