I have a 2013 SE with the base (non-touch Synch) radio. FM reception is fine, but the AM reception has deteriorated over the past few months. I now hear static on local stations that normally would come in very clear. I replaced the antenna stalk (but static/whistling still exists).
I also have started to hear a whistling noise that seems to vary with the speed of the climate control fan. This (along with the new antenna not helping) makes me believe I may have developed a wiring/grounding issue.
Has anyone experienced similar deteriorating AM reception issues, and if so, what was the fix?
Any other ideas on what may be the cause?
