I have a 2011 Honda Ridgeline RTL with Navigation/SiriusXM and I am the first owner. I bought it on 10/03/2010 and have never had this problem. Yesterday, I started the vehicle for the first time in only 2-3 days and it asked for the Security pin. Fortunately I was able to browse this site and find the pin via the sticker in my glove-box. I thought the problem would go away, but today (1 day after first incident) I started it again and it asked for the pin. Now I'm worried. I had a full dealership service/inspection at the three year mark only about 1-2 months ago, everything passed with flying colors. The battery has never caused any problems and there is no hesitation/bad sounds when i start the ignition. Is this going to happen every time? What are my options? I appreciate any help that comes my way. Thanks.
