Ok...I've experienced this 3 times now. The first 2 times I thought it was my imagination. But the last time....I'm positive that I accelerated and the MPG gage went up to 0, then I let off the gas since I was coasting to a red light and the needle didn't budge! It stayed at 0. I got to the light and braked and the needle was still at 0! Finally I turned off the car, forgot to put it in park, so it told me I had to have the car in park to start it, got the car started again just before the light turned green. The gage was back in working order then. Has anyone else had this problem?
