HI,

This morning I was unable to open the door locks with the key fob, rear lights didn't flash like they normally do. I opened the door the old fashion way using the key, tried to start the 300 and it wouldn't start typical symptoms of a dead battery, no interior lights etc...

I tried again a couple of minutes later, and everything worked fine, car started up. The power up window feature quit working. I checked the manual and it stated this feature would be lost, if there is a "power disconnect." Easy enough to get the window feature to work.

I took a look at the battery and "rear power distribution center" box. I noticed the positive (red) cable that runs from the battery to the "rear power distribution center" box was not tied down with a nut at the terminal in the "rear power distribution center." The cable seems to be mounted in someway, because I couldn't move it. I don't think its melted into the plastic, but it could be. Before I call the Dealer Service department, has anyone noticed if a nut is used to lock the cable to the terminal? Has anyone heard of this problem? Kinda think I have a flaky battery or connection. I did re-seat the fuse and relays in the front and rear power distribution center's.

Thanks in advance
Joe

What's the problem if your car has no power what so ever. Drove it this morning and after a couple hours it wouldn't do anything at all..

Define "wouldn't do anything at all". Doesn't start? Doesn't crank? No power even for the dome lights? Did you have to use a physical key to get in?

Wont do anything period

No power dome lights dont come on

It's difficult for me to imagine a battery going completely dead (not enough power left even to turn on a dome light, dimly) in only 2 hrs of sitting there, even if you had left the headlights on by accident. Was everything off when you shut it down? Sometimes a battery can get so old and weak that you can't crank the engine, but still it should light the light bulbs at least dimly. I did have a car with a loose battery terminal that seem completely dead in 20 minutes of grocery shopping. But it still turned on lights; it just wouldn't crank the engine. Tightening it up again fixed that nonsense. Did you jump yours to get it going again? What year?

You are not giving many details about this incident, so even though I would like to help, I really don't know what to suggest. Did you jump the car to get it home? What happens when you got it home and shut it off again? Was the battery dead in the morning? Or was this shopping incident a one-time affair?

I will recommend that you go to Advance and have them load-test the battery to see what it's health is. Maybe the alternator has failed. Maybe the battery is at end of life. Maybe the post clamps have become loose or badly corroded and stopped making a good contact. Advance would probably be able to diagnose with their test equipment.

Just in case you don't know this, the power button on my 2020 does not turn the audio off like it did on my 2012. Instead it turns off the screen.
