Hi, welcome to Just Answer. I’m Ron and I’ll be helping youtoday.Before we get started though, Please understand that I don't knowyour skill level or tools you have to assist us. Also understand thatI can't see, smell, hear, or touch the vehicle either, so patience isappreciated. JA is a great Q/A site, but it does NOT replace arepair shop.My goal is to make you happy and get a great rating in return formy time. Sometimes I have to give you bad news that I know youdidn’t want to hear, so please don’t shoot the messenger.
It will be difficult even for the dealer to identify this issue seeing that it is so intermittent, and i know that is frustrating. I attached a doc for you to read concerning your security system though. Unless there is a flash update for the system, they will most likely do what I just sent you.
