Dead Battery on my 2013 300S

eddiedav21 · 01-23-2013, 01:47 PM

Hey All,

I've had my new 300S for about a month with zero problems until this morning. I had left it in the garage while I went out of town for a week and was very disappointed when i tried to start it this morning as the battery dead. Fortunately I had it backed in the garage and was able to jump it and now it seems fine but was curious to see if this is a problem with the vehicle. I called the dealer and he said that I may have left the ACC on when exiting the car...

Has anyone else experienced dead batteries with their 300's after a few days of not starting it???

Thanks!

I see another thread about it here:

dead battery

Was your sitting on the dealer lot long? The newer cars do have a parasitic drain and sitting much more then a month can really weaken a better.

Also, once a cell has been fully depleted, they are less likely to take a full charge.

I'd have the dealer replace the battery.

Left the ACC on, really?
Next time it happens call the stealership for road service so that they can witness the condition first hand.

Not sure how long it was sitting on the lot... It's a 2013 and i bought it in December... I did notice that my IPod was connected into the usb the whole time but that would not cause the battery to drain would it?? The dealer is just over an hour away so hope it was an isolated incident and I don't have to drive all the way up there.

I would not guess the iPod. My understanding is once the car is off, so is the USB port.

I've got a 2013 and haven't had this problem. I've had the ACC stay on before, not sure what I did to make this happen. If I would have gone out of town the battery would have been dead by the time I got back for sure.

No problem here; didn't pull the battery for the first month of winter storage and she fired up just fine, voltage fine, everything fine.

Take it to the dealership; battery is under warranty for the first little bit too.

You don't have to manually turn ACC off, it goes off with the car - just like every other module does.

That makes no sense. Why would Chrysler allow the ACC to use any amount of energy when the vehicle is turned off? The ACC only needs to work when the vehicle is in motion, it certainly makes zero sense to have it consume energy when the car is off.

I could understand lights, stereo equipment or other equipment like that to still drain the battery when the car is off, but the ACC certainly makes no sense in this context ...

It could also be a parasitic draw or small ground issue that killed the battery.
