Several times I've unknowingly hit the trunk release button on my remote when exiting the car which in turn turns on the trunk light but does not raise the trunk enough to make it noticeable. Then I return a few days later to a car that won't start because the battery is discharged, but not enough for the clock or radio to lose their settings. I charged the battery up and I'm driving the car but now the speedometer doesn't work, the temp gauge is intermittent, and the Service light flashes constantly. Anyone have any idea what the heck happened?

Thanks,

Tim
