Other Fuel System Tank Assembly problems of the 2009 Mazda MAZDA6

There have been problems with other Mazda cars that got recalled due to a possible faulty fuel shut-off valve that could allow gasoline to enter the fuel tank emission system. If enough fuel gets into the system, it can cause the engine to stall. However, this recall did not cover my 2009 Mazda 6 and I had the same problem. Door lock actuator has failed! the alarm on my Mazda goes off at random periods of time. Sometimes its once a week and sometimes is 5 times a day or night. I have reviewed several internet forums and it appears that there are a lot of people with the same problem but they have not created a complaint on this website. The remedies that they have found to have the dealer replace a door actuator that is faulty. This door actuator locks the doors and if when it fails to properly lock the door it will intermittently sound the alarm. The alarm is not so much the concern as much as the door lock actuator. It if fails to lock it creates a safety hazard for people as they are driving down the road the door could accidentally be opened. Children could open the door and fall out of the car as it is failing. Please look into this issue as it is a safety concern. This has been happening for at least the past 4-5 years.
