We came back from a 5 day trip to find our RDX battery totally dead in the garage. No door ajar, dome light on, or anything.

I jumped the RDX and it worked great for 4 days, then refused to start again one morning again dead battery. Called TLC for a jump and drove it to the dealer. They found nothing wrong.

It's been a week since and the car seems fine. Anyone else have an unexplained dead battery issue happen on an RDX tech?

Ours is an 08 model.

 

Mine is an '07. I car pool, at times, and my battery wouldn't last 3 days just sitting. They found the problem in the amp of the sub-woofer pulling the battery down. It was a known issue. Check it out.

 

So far so no problem with mine. plus I change the Battery when I got the car.
Optima Red top.

 

I thought it was a battery problem also last winter, so they replaced it. This was before car-pooling cause I was driving everyday. Then car-pooling let it set for a few days, and down it went in two days.

So I had them check it out again by keeping it at the dealership. It cranked for them. Got it back and it happened again, so they kept it again. This time they saw it. Found the problem, and is fine now. It can set for at least 5 days, that I know of so far, and no problem.

 

Mine has been good, the battery is a bit weak in the cold, but I've left my car for weeks without issue.

I'm guessing something is draining it or you have a dud battery. It's definitely not a normal condition.
