The electrical system in my Saturn Vue just dies sometimes. It won't start; if I wait for a while it might start and act like nothing is wrong.
Also my "Service" light comes on intermittently; I do not get any codes when I read the computer
The BCM (body control module) is a problem on these cars it works one day and not the next,also controls the lights, security, door locks, etc this computer is usually very expensive and dealers charge around $800 the replace and reprogram it.
HAVE THE BATTERY CHECKED OUT.IT COULD HAVE A CELL PLATE SHORTING ON INSIDE SEE WHEN YOU DRIVING YOUR THE MOVEMENT OF THE CAR RIDING ON THE ROAD CAUSES SHORTED CELL PLATES IN BATTERY TOUCHING EACH OTHER .CAUSING ELECTRICAL PROBLEMS IN THE PCM.
