A couple days ago, the battery in my '09 Sport (10K so far, almost 9 months old) went flat. Didn't leave any lights on, no accessories connected, nothing that explained it whatsoever.

Next morning, same thing. After driving around to recharge, put a multitester on the battery, and it was very slowly creeping down in voltage--12.35, 12.34, 12.31--dropping about a hundredth every few seconds, as if the tester was slowly draining it. Weird. Overall, it was losing about a tenth of a volt every hour or so, and when it got down to just above 12 volts, it would barely start.

Today, the dealer tested it and replaced it as defective. Covered under warranty, no charge.

Thought I'd share in case anyone else runs into this problem.

 

thats good to know, thanks for sharing doode.
