I’ve been having a bit of a problem with my 99 Nissan Sentra that is becoming more and more costly every day. It started with my airbag light flashing, so I pulled over to see what might be wrong. I turned the car off, and when I went to start it again it wouldn’t start. I had the battery checked out and it was fine; I ended up changing the starter and the ignition switch. This worked for a week. Later I left my car running in the morning to warm it up, and it did the same thing, the airbag light came on and the battery went dead. I jumped it and the battery wore itself out again, so this time I took it to the mechanic to replace the alternator. This worked for a week. This time my wife was driving down the highway, the airbag light came on again, and the battery went dead. After a costly tow from the police impound to my home, it will jump, but the battery slowly dies. I would love some advice before I end up taking it back to the mechanic again. The only noticeable problems the car has (aside from the obvious battery going dead) is that there is a belt that squeals when I have the air conditioner turned on and I have an oil leak somewhere. Someone help me before I waste any more money! My best guess is that someone has put a voodoo curse on my vehicle.
