I have a 2010 RT with 12K miles on it and I've heard a single random chime, similar to the noise heard for low fuel, tire pressure, etc.., but no service lights come on. It has occurred about 3 different times over the past month and I can't figure out why. It seems to happen when I'm on the highway going 65-70. Has this happened to anyone else before or does anyone know why this would be happening?
(I apologize if there's already a thread on this, but I searched and found nothing)
