Driver side door locks are malfunctioning. the system says the door is open when it is securely closed. The system won’t turn off interior lights which drains the battery. It also won’t allow locks to lock thinking the door is ajar. There are recalls for this issue on other Ford SUV’s but not for the Flex.

Door latch sensors are faulty. We replaced the front passenger latch sensor in april 2017 and now need to replace the back passenger latch. Because the electrical/security system tells the car the door is ajar, it does not allow the power locks to function while the car is running. It also drains the battery by not turning the interior dome light off as well as setting off the car alarm unpredictably. The interior dome lights also come on while the car is driving, which is distracting to the driver.

Power steering quit while in a parking lot. I stopped, shut off the vehicle, and it reset. The passenger side door ajar light constantly stays on, even though the door is shut. This will not allow the doors to be locked, and the interior lights stay on until the vehicle reaches 15 MPH. It has also caused the lights to stay on inside the car, draining the battery.
