Hi guys I own a 2008 G8 GT and the remote start feature recently stopped working. All doors, hood, and trunk are closed, etc. etc. The car locks just fine before hitting the remote start button twice, but the lights no longer flash when pressing the remote start button twice. There's no check-engine light and the remote/key fob is only 6 months old so the battery is still good. Any ideas on this one? Thanks!!
