NHTSA Complaint #11573757 — 2021 HONDA PASSPORT

I purchased my vehicle in August 2023 (used). Phone calls (both through using CarPlay and with the phone unplugged and with genuine cables) sound terrible on the part of the recipient. We replaced the FAKRA cables and harness late last year and just replaced the microphone (and I got charged a diagnosis fee). The issue is continuing. It's gotten so bad that I have to use my AirPods to make any calls for my recipient to hear anything I'm saying (which is illegal in my state and should not be a requirement in a car that is less than 3 years old). I've dug in to forums and this is a common issue for the EX-L trim level in the 2021 model. Additionally, this can impact the backup camera and other lane keeping assist issues. I have factory reset it multiple times and it's still having similar issues.
