Dead car!

[Melow]

Ok, so I pulled it in the garage to detail it, it sat for a day or two, went to pull it out this morning and, nothing. No lights, no nothing, like there wasn't even a battery in it. I pulled the battery to charge it, and it's fully charged. Charger won't work while connected, seems like some kind of short, but don't know where to look, any ideas?

Did you disconnect anything before the cleaning? Did you spray anything with a power-washer under the hood that could now be shorting out or out of place? This sounds like the most likely situation from what you've provided.

Did you check that fuse in the holder right by/on the positive battery terminal?

Many on here have had those totally corrode out from terminal acid buildup (yet another reason why I am installing a no leaking, AGM battery Monday ).

Any interior lighting or electrics coming on?

Is the starter soleniod even clicking? My starter got intermittent after 4 years and 105k miles.

Hook up the battery right

 

[Stupidbutt]

Don't wash the key fob.

 

[Melow]

Ok, so I hooked the battery back up, still nothing. Then I locked and unlocked the doors with the key fob and it worked. Opened the door and everything worked, started right up. Weird.

Crazy how if you just take a second to think.....you will get it


Vs spending 20 minutes running to the forum. Good job

Odd. Might have tripped the anti theft or something

 

[Stupidbutt]

I agree - sounds like the anti theft kicked in.

It did it again today. Pulled the car up to my garage, got out and went to lock it, and nothing! Nothing works again, so it wasn't the key fob, I tried both, battery couldn't have died on both at the same time. It's a 2019 with only 8500 miles, no corrosion around the posts, cables all look brand new. Any ideas before I call a shop?

Sounds like a job for warranty repair. With a loaner car while they have it.

 

[Melow]

Another thing I found odd is the Accessport had power, its the only thing on the car that works.

 

[SteveS]

Sounds like when you get it on again you need to take off the accessport and see if that solves the problem.

That's what I was thinking. I took it off and unplugged everything just in case. Still need to flash it back to stock before I take it in

 

[Stupidbutt]

Do you have a slot in the Accessport for theft deterrence? Maybe it is defaulting to it?

 

[TyphoonFiST]

How old are the key FOB batteries? If you don't know replace them BOTH.

You don’t have to reflash. They will still know, anyway. There’s, I believe, a count of flashes that is not eraseable. And, what you’re describing doesn’t look like it is related to the tune.

Did you detail the engine compartment?
