2009 Ford Flex electrical problems

Filed Dec 9, 2025 · Electrical · KS

You can be driving down the road, and all your gauges will stop working, and all the warning lights on the dash will light up. The first time this happened my wife got stuck at a gas station all the warning lights were on and the car would not start, people tried to jump it and it would not affected at all. I looked on the internet and found were someone said to beat on the passenger side floorboard, I called my wife and told her to try that, and when she did the car would start. It doesn't do it all the time, you never know when it's going to happen. We have to just stomp on the passenger floor to get everything to start working again. If I had not found this information from somebody else on the internet my wife would have been stuck about a hundred miles from home. I've taken it to the Ford house and they say they've never heard of anything like this but I know it's happened before two other people that's how I knew to stomp on the floorboard on the passenger side.

The door ajar sensor malfunctions and is crazy expensive to fix. There are numerous posts and videos online of workarounds bcz it’s so common but they don’t seem safe since that’s a safety feature and the workarounds are simply a way to trick or bypass the warning sensors since the doors are actually closed in most cases. Ford needs to take ownership of this and issue a recall. There’s a tire pressure sensor failure as well.

When driving down city highway or city roads the all of the lights on the dash board will cut off, (ie. Radio, blinkers, heat & A/C controls) will shut off and the drive control button will appear with the door ajar and brake lights. It is now starting to make a dinging sound while you drive as well as smell like something is on fire. The car is completely shut and sealed. There isn't a time or instant where this is happening. It will just go in and out! Ford you really need to fix this problem since families are using these vehicles. I've done some research and see that it is a common problem with the 09 flex.

Passenger door ajar dash light goes on and off when the door is secure and locked. Interior lights go on and off when ajar light is displayed and power locks unlock/lock at the same time. This is a serious issue at night when the interior lights go on and off the entire time when your driving blinding you as well as I have been pulled over because they thought I stole the car. While pulled over I was asked to step out of the car and when I exited the car ibecame possessed and the alarm went off and interior lights began blinking and flashing on and off. The car alarm consistently goes off at all hours of the day and night causing the battery to go dead if your not around to shut it off. This is also issue as my car can get stolen at any time if the factory alarm isn't working or I could get carjacked because the doors won't stay locked.this issue happens in park, in drive and reverse. It happens while driving or idling as well as it occurs on the highway and city streets. I have read many other reports and ford needs to address this in the 2009 flex as well.

I purchased this vehicle in may, 2014 as a used vehicle w/warranty (powertrain). While traveling from st.louis, missouri in stop and go traffic, the car overheated. After speeding up to get out of traffic it suddenly cooled back off. Now, during this same time, the air conditioner stopped blowing cool air until we sped up to get out of traffic. After that, it didn't happen again until I was stuck in traffic. Same problem. The fans stopped working. Here recently, I was stuck in traffic and the car overheated and the check engine light came on. Only this time, when I sped up the car didn't cool down. The coolant was fine but the car still over heated. I took the car to the dealership today and was told that it is the cooling fan module and it should be replaced. Now, I've read in several different places that this is a problem with 2008-2012 ford flex vehicles. A recall was issued for the 2011-2012 series but not earlier models. Owners of these vehicles should not have to be responsible for faulty materials used to make these vehicles. The same recall that was afforded to the 2011-2012 models should also be afforded to owners of earlier models. The dealership wants $600 to repair this because my warranty only covers powertrain. Please address this asap. I have 6 children and cannot afford to spend $600 on something that is not even my fault or the fault of normal wear and tear.
