"Battery Saver Mode"...???

At least a week ago I noticed this email like icon on the information display. I thought it had to do with the Bluetooth or something. I finally figured out it was a message that reads "Battery Saver Mode".

It will not clear, been on constantly at least a week and a few hundred miles - no symptoms. Battery seems strong...cranks right up even when 30 degrees...

Ill show the dealer soon when I get the two new front wheels.....any hints as to what this is?? One of the few things these cars seem to lack is an ammeter...

I was going to post this same subject. It's been 0-10 degrees for a few days and I have been using the remote start more. Like you the one day I had a message and sure enough it was the battery saver mode. I did just get the message once this was 2 nights ago. I did not get it today. My guess is its just minimizing power so the battery can recharge quicker with the alternator due to extra drain on the battery. Just taking a guess here

I have a 2013 AWD RT

lg, I'm betting that this is some fancy computer controlled setting that is glitchy...

Think about it....370 hp and Dodge couldn't simply put a bigger alternator on the car??

But I have been using the remote start a lot. And on another forum I noticed folks tying the remote start to this message. I'll not use the remote a few days and see if it clears.....

The message is due to low battery voltage. The link to remote start seems coincindental since it's usually only employed in very cold weather.

The root cause appears to be a bad alternator (factory defective) that isn't charging the system properly. Several have fried and at least one customer had it catch fire.

The system is designed to reserve enough power to start the vehicle and doesn't let you run the ancillary systems and draw the voltage down below an acceptable "start" charge. The issue appears to be that the system isn't recharging the battery enough and the "battery saver" program is kicking in.

Now that it's cold enough to expose this issue, expect a TSB from Chrysler soon.

DDaddy that makes sense....

Now that you explain it that way, it does seem like sometimes the seat heaters are very slow to work and other times they fire right up......that could be the system activating....

I will be at the dealer in a few days anyway getting 2 new wheels, they can check the alt.

thanks much

Now does this make the car more "interesting" to drive knowing it may spontaneously combust on you?

But on a more serious note..... this battery saver mode is this only on the new chargers or do the older styles have it also?

O ok, thought this seems like good idea, makes the car more idiot proof for the general driver.....if they pay attention to the dash lights!
