2012 Ford Edge: battery drain or dead battery

Filed May 22, 2026 · Electrical · FL

RE:Safety Complaint - Defective FCIM Causing Hazard Flashers to Activate Randomly May 22, 2026 To Whom It May Concern, I am writing to formally complain about a serious electrical defect affecting my 2012 Ford Edge involving the Front Controls Interface Module (FCIM). The vehicle’s hazard flashers activate randomly and repeatedly without warning, even when the vehicle is completely off and parked or operating normally. This issue appears to originate from a failed or malfunctioning FCIM module, despite the vehicle not being abused, modified, or involved in any event that would reasonably cause this failure. This defect creates multiple safety concerns, including: - Unexpected flashing while driving - Battery drain while parked - Driver distraction - Potential confusion for surrounding traffic - Loss of confidence in the vehicle’s electrical system After researching this issue, I discovered that many other Ford Edge owners have reported nearly identical FCIM-related failures, suggesting this may be a widespread defect rather than normal wear and tear. I am extremely disappointed that owners are being forced to pay significant repair costs for what appears to be a recurring design or manufacturing problem. Electronic control modules should not fail under ordinary use conditions in a manner that compromises vehicle safety functions. I respectfully request that Ford: - Investigate this recurring FCIM failure issue, - Offer goodwill repair assistance or reimbursement, - Consider issuing a technical service campaign or recall if appropriate, - And acknowledge the safety risks associated with malfunctioning hazard systems. I have been a Ford owner in good faith and hope the company will stand behind its product and assist customers financially experiencing this defect. Please contact me regarding the next steps toward resolving this issue. Thank You. Sincerely, [XXX] [XXX] [XXX] VIN [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driver door ajar warning light stays on even when the door is closed. It drains the battery.

Takata recall my passenger side "door ajar" light stays on at all times. This causes my battery to drain and prevents the car from locking. It also keeps the dome light on while driving which is a problem when driving at night. The doors will not lock which makes it very unsafe when in public - my children are in the car but it will not lock until it is driven for a distance. This does not help in a parking lot when car refuses to lock due to a bad sensor. Now, my driver's side door is starting to alert that it is ajar. Both doors are always closed. The driver's side door again, will not allow the car to lock and alerts me to shift my vehicle into park. This cycles 24 hours a day. My lights will randomly come on for no reason other than a bad sensor saying doors that are shut - are "ajar". This has left me on more than occasion with a dead battery. This most certainly is a safety issue concerding the doors are designed to lock automatically when driving - and they will not due to this problem. I will never buy another ford again unless this is fixed. I am requesting this be recalled as it is a known problem. I was advised it could be fixed - but it will return. I do not have the funds as a single mother to do so. Please ford - take care of this problem.

Drivers door is incorrectly reported as being open, interior lights are turned on, parked or while driving and stopped at traffic lights, impairing visibility outside at night. Secondary prevents doors vehicle from being locked by external pad when parking the vehicle as well as keeping lights on draining the battery. Trying to open/close door multiple times eventually resolves, but gets frustrating when it is 5+ min trying to do this in rain or in parking lots this has been increasing in frequency and more frequent in cold weather than warm..

Driver's side door sensor. Vehicle warning light days driver's door is open when it is actually closed. Problem prevents auto door locks to engage and keeps interior lights on when door is locked and ignition is off causing battery drain.

Door ajar notification stays on when door is closed, running, and while driving. This causes the lighting to remain on thus draining the battery.

Door ajar light stays on after car door is shut which in turn leaves your dome lights on which in turn will run your battery dead. Doors will not lock and that's a safety hazard if you have children in the backseat

Door ajar sensor is failing. Door ajar message stays on with door closed (driver's) making driving very difficult with constant warning beeps and dome light on (even at night). I have to open and shut the door multiple times very hard for it to go away. Many many people have had this issue, and apparently it progressively gets worse until they have constant beeping warning, dome light on while driving at night, doors that won't lock while driving and the constant risk of a dead battery after returning to their parked vehicle. I've already had to buy a new battery due to the dome light staying on after parking. This is very dangerous and deserves a recall. The current fix apparently requires replacing the entire latch for around $400, every two years on average. This is ridiculous.

Malfunctioning door ajar sensor stays remains when door is securely closed. Can drain the battery. Had the sensor in driver's door replace while under manufacturer's warranty. The replacement sensor is now malfunctioning and the vehicle is out of warranty.

The driver's side door ajar is constantly on. I have opened and shut the door multiple times and even tried to do what some youtube videos have shown. Dome light sometimes stays on after I park, sometimes goes off. I will have a dead battery and probably additional costs unless I want to pay $400+ to ford to fix this known issue.

The driver door and rear driver door "door ajar" notification's do not turn off, even when the doors are closed. This causes the dome lights to stay on which drains the battery, and then the vehicle will not start later. This also prevents the doors from locking while driving. This is an ongoing issue and can not seem to be resolved, even after a mechanic cleaned and lubricated the door latches.

There has been a service bulletin issued for a 'door ajar' warning when the car is started caused by the failure of the drivers door latch. This does not go out when the car is turned off. This results in the dome light staying on and draining the battery. Not repairing could result in the inability to lock the vehicle electronically. The failure usually occurs after 50k miles, leaving the owner to pay for a common and expensive part failure. I
