I have a 2005 Mazda 6 which has served me very well, but I am having an intermittent problem. Periodically when I turn off the car, my gauges flip back and forth several times. When this occurs I cannot start the car until I pull the negative terminal of the batter for 10 seconds and reattach it. After this the car starts right up and will start up normally for a few weeks. I have replaced the battery on the car the first time this problem happened so do not believe the issue is the battery. Especially when it starts right up after the unattach, reattach process. Any ideas out there?
