My 2018 Clarity Touring came with a factory-installed Sirius/XM radio. For the past few months, it occasionally loses signal and displays "No Signal" on the screen. Sometimes it comes back in a minute or two, but more often it remains off so long that I wind up switching to FM. I have had two other Hondas and a Suburu with factory-installed radios, plus an older Pilot with one I installed myself, and this has never occurred in any of them until now. I took it to the local Honda Dealer on 2-21-2022. They found some error codes and said that if the problem occurred again they would replace the radio and/or the antenna. The problem has continued off and on, so I made an appointment to begin the process today. The technician said he could not find anything wrong, so he did nothing. I finally spoke with the general manager, and he insisted that they can do nothing unless the radio malfunctions in their presence. I showed him one of several videos I have made while driving down the highway displaying "No Signal" when there were obviously no obstructions. He still insisted that they cannot do anything about it unless they witness the malfunction. As an engineer, I understand how frustrating intermittent problems can be. Sometimes the only solution is to start replacing parts--beginning with the least expensive--and eventually finding the fix. Have others had this sort of experience? And if so, how did you resolve it?
