NHTSA Complaint #11471488 — 2017 HONDA ACCORD

The rear camera system/speaker periodically gives a screeching static sound which was so unbearable until Team Honda (Lafayette, LA) had to disconnect the entire system. I researched this issue and conclude it must be a factory defect because 1) due to the low mileage and infrequent usage of this vehicle 2) the commonalities among other 2017 Honda Accord Drivers with the same issues who are from different regions, and because the speaker works when I plug in my iphone. Team Honda wants me to pay $1200 to install a new one because the original factory system is out of warranty. Should the manufacturer be liable for any parts of this system ? Should I have to pay the cost for a defective vehicle and jeopardize my safety and be left without a radio for safety information, camera, and a GPS? This is not my first Honda and had no issues with the previous one which is another reason why I know this is not human error. Can you please investigate this and share with me your findings. I paid $99 for them to disconnect my audio visual system on my car and received no explanation about the error. Thanks.
