Had a strange thing happen to me the other day. I parked the car at the airport as usual, and left on a 4-day business trip. When I got back I went to open the trunk, but it wouldn't open or recognize the key.

I opened the drivers door and went to start the car. It clicked a few times, and then the clock started running backwards...then forward. I got a message or two on the instrument panel - about all I remembered seeing was something about convenience items not working, and something about the brakes.

I sat there a few minutes and the clock finally stopped - back at the right time - and the car started - albeit not turing over too fast.

The battery was replaced about 5 months ago.

Now I'm a bit worried about leaving it at the airport this week.

Anyone ever have this happen to them?

That's a dead battery. Is the new battery a mercedes? The car should have a reserve one-time charge to start the car in the case of a dead battery. That's why it started. You have find out why the main battery drained.

 

Mine did the same thing.The SAM was going bad and would drain the battery over night.Warranty fix.

 

Thanks guys for your thoughts. I think something is draining the battery too, and I suspect it will need to go to the dealer. Thanks goodness for warranty!
