general problems of the 2003 Nissan Altima

2003 Nissan Altima 3. 5l v6 se - the door locks keep locking repeatedly. Will do this while I am in and out of the car regardless of key fob use. My hazard lights flash each time. This has been ongoing for over a week and has increased in frequency and duration. It is now constant - going on every 3-5 seconds. I had trouble getting my daughter out of the car because the door kept locking on me. I worry about the ability to get out quickly if needed. It brings attention to my car throughout the night. I believe this is a safety issue on many levels. It has not been fixed yet. I have been told it may be the door lock actuators.

Started approximately 2 years ago. Driver and passenger windows won't go up all the way and if they do then they roll down all by themselves. They go up and down at all times of the day and nite. The car automatically locks itself whether the keys are in the ignition or not. You always need to have two sets of keys because if the window is down and you reach in to unlock it the alarm goes off as if you are trying to break into the car. Door that goes over the gas cap bent during regular use and would not close. Nissan said there were no recalls on this item and just to take it to a dealer and pay to get it fixed. Saw several other Altimas of the same vintage with the same problem.
