My 2004/63,000 mile has been having the random siren chirping problem. Today dealership told me it would be $800 to replace the siren. They said they cannot disconnect the siren due to a communication wire that leads to the motherboard and that a siren "has" to be present because of this wire. I'm thinking they don't want to mess with it? Considering taking it to a car audio place instead?
This and one other needed repair will make or break whether I let some enthusiast take the car off my hands. I'm just an everyday lady driver and not a tinkerer.
