After putting the car in drive the auto lock keeps trying to lock the doors, the interior light comes on and the car dings relentlessly. After 100,000 miles everything starts to break or malfunction on this car. I rate this car as a "throw away" car. I haven't found a solution to this problem anywhere online and I'm not about to pay a dealer a repair bill. If anyone knows how to fix this problem please tell me.

After I get in the car and head down the street, my car will ding with the Door Ajar warning. The locks will engage & disengage and the interior lights will stay on as if the door were open. This is freaking annoying!! Often I drive to work with my interior lights on because I can't figure out what is causing this. No matter how many times I slam the driver side door shut, it will keep up.
