Hi, I have read threads regarding the AM crackling noise that occurs when going over bumps or traveling on bad roads. This is occuring with my 2006 Ridgeline as well. I understand there is a TSB for this, but is the dealer obligated do the work if my truck is out of warranty?

My AM radio has an intermittent disconnect with the antenna. It creates a loud static noise and sometimes comes in fine. Most of the time it's low volume and staticy. I took my truck to the dealer and they said the disconnect is a coax connection up in the headliner. They said it would cost $500...
