I just bought a 2000 Dodge Durango with over 100,000 miles on it, but it has a new motor. It seems to run fine and everything works, but when left over night it appears to be dead and won't do anything, the key fob will not unlock the doors and the power door locks will not work if I use the key to open the drivers door. It doesn't do it everytime either, just like every other day or every two days. When it doesn't start, we just jump it and it starts fine. Runs all day, starting and stopping. We have driven it 1500 miles in the last 2 weeks on a trip. Just when we leave it overnight it acts like the battery is dead, nothing makes even a click, no gages register, lights don't work, just like it would be dead. We have tried everything we could think of to do manually to get it to work, all it takes is a jump for only a second. I haven't had it long enough to know if this is going to be occurring at regular intervals. I took it into the Dodge dealer and of course it wouldn't do it to them. They said they had no idea what could be causing the problem, as everything that it might be checked out, alt, starter, etc. & no codes. They said that they would have to just wait until it did it to them. Well, I can't just leave it in the shop for days, hoping it will happen. I originally thought that it was the battery, so I replaced it with a new one. Didn't fix the problem though. I am at my wits end....somebody please give me some ideas! I got it back from the dealer today and I'm gonna bet it will be dead in the morning!
