I received my 2001 gg/nav a few months ago and have been loving it right up until the engine light and the VTM both lit up. I took it in and they told me rats have been eating the wiring. I live in the Santa Monica mountains which is paradise except for this dirty little secret about its robust rodent population. It seems they like the warmth of the engine and are inclined to pass the night away nibbling on the hard rubber to keep their teeth from getting sharp and long enough to where they can actually hurt themselves and their friends. Needless to say rat teething is not covered under warranty. Any suggestions?
