My battery is driving too quickly

I have had problems with my 2006 Lexus GS 350 I bought four months ago from a NZ dealer. The problem is that the battery drains itself out very frequently. The dealer has replaced with an old battery on three separate occasions, and once with a new battery. Even Toyota could not fix the problem despite keeping the vehicle for six weeks, and vehicle did not start yet again on the day of return. I just wanted to know if this is a common problem with Lexus or could it be the inefficiency of the dealer to have not carried out a thorough inspection prior to selling it?

It’s not a problem with the battery, and replacing the battery won’t fix it. There’s a leakage somewhere that’s causing the battery to drain. It will be something that’s not turning off when the car is turned off, like a computer, a light, or something that’s staying on all the time when it shouldn’t be. Try an auto electrician.
