Brake light + automatic lock door problem

[weskereric]

Sometimes the red light of brake is on but my handbrake is released, brake fluid leved is good and rear brake stop lights are good too, what would it be ?

Another problem is that I can't lock my door from the button inside the car when the car is running.

Also the auto locking is not working : the auto locking try every minutes to lock the doors but it fails, what would it be ?

Thank you

Sounds like a door/bootlid shut sensor has gone awry. Check your door open warning isn't on, and that all the sensor switches are contacting properly.

 

Failing which, you should probably check for fault codes.
