What is the reason why the Ford Kuga driver's door handle sensor door cannot close after opening?

For the automatic door, it is recommended to disconnect the sensor signal line to check whether the automatic door cannot close due to sensor interference signals. The following is relevant information: 1. First scenario: The automatic door remains open. The cause of this issue may be a damaged sensor that continuously sends an opening signal to the automatic sensor. It could also be that the automatic door's remote control or mode switch is adjusted to the open state. If an access control system is installed, the relay of the access control system may be damaged. 2. Second scenario: The door moves but cannot close. The reason is that the sensor has an opening signal input, meaning there is an interference object within the sensor's range, such as direct sunlight, moving objects, or unstable light sources. Through the above analysis, the automatic door issue should be basically resolved. In practice, automatic door maintenance should proceed from simple to complex, first eliminating simple fault causes and then gradually troubleshooting. Another possibility is automatic door opening.

Last time I drove the Kuga, I encountered the same issue—the sensor for unlocking was super sensitive, but no matter how I pressed it, the locking function wouldn’t respond. Thinking carefully, it might be that the sensor on the door handle was dirty or had dust buildup, especially after rain or car washes when moisture makes it more prone to malfunction. Another possibility is low battery in the key fob—unlocking might still barely work, but locking could fail completely. I first tried replacing the key fob battery myself, and sometimes the cheapest fix is just a fresh battery doing the trick. If that doesn’t work, check if the door is fully closed, as the sensor won’t respond if the door isn’t securely latched. As a last resort, take it to the dealership for a technician to diagnose whether it’s a circuit or system bug requiring a software update. For daily maintenance, I often wipe the handles with a soft cloth to keep them clean and reduce false triggers. In short, don’t overlook this small issue—after all, an unsecured door isn’t safe.

I've dealt with the issue of the Kuga's touch-sensitive door handle a few times, and the core of the problem lies in the smart key system: sensors detect your touch to open or close the door. If it only opens but won't close, it's likely due to a damaged sensor or signal interference causing the malfunction. For example, if a phone or electronic device is too close, it can interfere with signal transmission, or if the key battery is old and low on power, the stronger signal needed to lock the door might fail. I've tried using the physical key to manually lock the car as a temporary solution, then checked the trunk or other doors to see if they're affecting the system's integrity. Sometimes the system software needs a reset—try closing all doors and holding the lock button for a few seconds to let it relearn. If that doesn't work, it's best to take it to a professional shop to check the hardware rather than tinkering with it yourself.

Sigh, my Kuga's door handle won't stay closed after opening, really frustrating. It might be a faulty sensor component or the key fob battery dying. You could first try pressing the lock button on the key. If that doesn't work, check if the battery is low and try replacing it with a new one. If still no luck, inspect whether the door is properly shut - sometimes it won't lock if not fully latched. If the issue persists, head to the repair shop promptly, safety first - don't delay.
