How do I fix the common issue of the Ford S-Max automatically locking itself while driving?

I recently purchased a Ford S-Max and while driving, I noticed that the car would randomly lock itself. It's becoming quite a nuisance, as I have to constantly stop the car to manually unlock it. Are there any known solutions for this problem?

This could be a problem with your car's central locking system. It's best to take it to a mechanic who specializes in Ford cars to get it checked out. They will be able to diagnose the issue and provide a solution.

I had the same issue with my Ford S-Max. Turns out, it was caused by a faulty key fob. I replaced it and the problem went away.

You can try resetting your car's security system by disconnecting the battery for a few minutes and then reconnecting it. This has worked for some Ford S-Max owners with the same issue.
