iPhone 11 Pro Max - crackling noise with phone calls when connected to Car's Bluetooth

From past couple of months, there is crackling noise coming with every phone call made while driving with my iPhone 11 Pro Max connected to Car's Bluetooth. There is no distortion when playing audio, it's only specific to phone calls. iOS 13.2.3 didn't solve the problem. Removing and adding the Bluetooth device both from iPhone and Car didn't help. The only thing that worked is, Reset Network Settings and then Remove & Add Bluetooth device, but it's only temporary and the issue comes back in a day or two.

Did notice many threads with crackling noise with iPhone 11's speaker. But did anyone else having the same issue with Car's Bluetooth connection ?

Same exact issue with two different iPhone 11's in two different cars. Voice calls over bluetooth crackle and sound awful, but music over bluetooth in the same car sounds fine. There are a few groups on here with dozens of people making the same complaint. Never experienced this problem with my 6s. Waiting for a fix.

I have taken this to Apple. They ran hardware diagnostics and advised there is no issue with hardware and did a software restore and sent me back..but the first call I made after the software restore had the exact same issue. Going back again to Apple, hopefully they acknowledge the problem. :(

Here’s a short update - on second visit Apple replaced the phone. The replacement phone was working perfectly good in the initial tests. However once I updated it from iOS 13.1.1 to iOS 13.2.3 the problem came back again! Although not many hopes, I will give a try updating the Multimedia firmware on car to see if it goes in sync with Apple’s updates. If not, the only hope is iOS 13.3 will fix it.

Did the iOS 13.3 update fix the Bluetooth phone call distortion issue???

In my case, I had to update my car’s firmware along with iOS 13.3. While it’s not 100% without distortion, call quality is much better now.
