So came back from vacation and guess what, battery dead again. This is ridicuolus, this is a brand new car and should not be dead after a week of not being driven. Today it is in for it's 5K service so I'm having them check the battery again, didn't bring it in dead but guessing they should be able to find what is going on. I might have to leave it for a week for them to see why it keeps dieing.

 

maybe you should try another battery (brand) and have Lexus pay for it, and see if that solves the problem. i'd am curious to see if that rectifies your problem. have you called LC to complain? they need to know that something is not right with these batteries. or whatever is going on behind the scenes to cause your battery to go dead.

 

There's got to be some kinda of current draw somewhere in the car that's sucking it down so fast.

 

A friend had a similar problem with his lexus. Dealer kept charging it and it kept dying. Eventually a Toyota dealer put in a different type of battery and it never happened again.

 

Man that sucks...Hopefully they can find and fix the problem.

 

I hope they can find this problem, it's kind of annoying. I really don't want to change the battery as its factory but they have done tests and found nothing. Anyone want a recommend a test they should try, thanks in advance.

 

Lexus is aware of the problem.

Yeah saw this, they had put in a TSB for it so if it occurs again I guess they will replace it.
