A problem that surfaced again after experiences many times since the above mentioned incident date: a wrench sign was coming on the dashboard frequently, and sometimes disappeared itself without doing anything.similar sign or indication for oil change was also experienced even after a scheduled oil change was done with the dealer. when the problem was reported in early period, i (the customer) was advised to disregard, because the mechanic forgot to reset after the oil service, when ford customer service was notified today (11/7/12), it was acknowledged as a service issue, which i do not agree. since the problem existed when the vehicle was new in early stages after the purchase, my concern is that this is a manufacturing defect with battery door which malfunctions, and does not allow ventilation on & off. the battery was down, all controls disappeared and the car was locked in position about two years ago (approximate june 2010). that time a major service was performed, which required a month long period to fix it. (safecar reference 365127). unfortunately, i never heard back from your office on this past issue and complaint. since both problems have to do with battery and monitoring devices, i would like to inform for safety of all using this model. please let me know your findings on battery vent door functioning. thanks *tr
