Hi guys, I have an 2008 is250 a few moths ago my battery started draining, I thought it was lights or something so I turned all inside lights off , including trunk, still persisted. Went to get it checked at Toyota they said battery so I got a new one

Problem came. Back a month later went back they did tests they say everything is fine so I decide to take the car to Lexus on the park ( Toronto ) they do their tests they can't find the problem, charge is fine, battery tests ok, they can't find irregular drain, today it is empty again

PLEASE HELP

OEM batteries are known to fail around 50k/5 years. It's time for a new battery. Even more so that you're in Canada in the winter.

Hello,
I had the same problem and I'm still waiting to hear back from Lexus Canada. I had a battery replaced on January 25,2013 and it was dead on February 9th, 2013. I was told my starter and alternator were fine and unable to find any external battery draws.

Once is hear something I will post on the forum. Good luck, if you purchased your battery at Toyota/Lexus they come with an 84 month pro-rated warranty; I realize this does not accommodate for your time

He already got a new one. Same thing keeps happening. Aoudad like something is draining it. That's the hard thing to find.

Are you sure? That was his first post. I don't see any background info on the problem other than an 08 in Canada with a dead battery.

So it slowly dies over a 2 week period? If it dies over night, I think you can start pulling fuses to see if some electronics is doing it.

Thanks that sounds like a plan, just to make sure we on the same page u saying the night before I pull a fuse if it does the same thing I keep trying different fuses overnight until I find the problem

You should check your alternator instead of Battery. Sound like you have bad alternator.
Head up to local auto parts store and has them test out the alternator.

I also thought it was my alternator so when I went to Lexus and they checked the system I specifically asked them about that and they said the charge system is fine, alternator is OK
