Acura TSX Bluetooth microphone intermittently causes loud ringing noise for callers on Acura TSX

Some Acura TSX owners report experiencing issues with the Bluetooth microphone, such as loud ringing noises during calls, which may be attributed to several factors. Instances of defective microphones have been reported, leading to significant audio problems. Additionally, Bluetooth connectivity issues, particularly with newer phones and software versions like iOS 10 or later, can cause intermittent disruptions. Compatibility between the phone and the car's Bluetooth system is also a concern, as trying different devices may help isolate the problem. Electrical issues, such as battery drain affecting the Bluetooth hands-free link, may necessitate a replacement to resolve audio problems. Some owners experience feedback issues from the hands-free mic located in the dome light, which can be identified by disconnecting it. Furthermore, newer phones using low-energy Bluetooth versions may introduce noise and interference, exacerbating connection drops and loud ringing noises. To troubleshoot, some users have found success by placing their iPhone in the sunglasses holder, turning off other Bluetooth accessories, and enabling airplane mode while only activating Bluetooth.
