Discharged Battery
Have'nt driven the 04 GS300 for about 3 weeks and I tried to start the car this morning but the battery does not have enough juice to start the car. Is this normal?

I had the same thing happen to my GS4 not to long ago. I used my little jump start pack, and got the car started. used it to run some errands, then parked it for 1 week, found the car to be dead again. battery was shot.
Somewhere in here there is a thread that talks about how some lexus batteries that came out werent very long lasting, I wouldnt be suprised if yours is shot as well.

Did you have some kind of light on? I have had my Gs430 parked for about alittle more then 3 and when i did started her up there was no problem. Try going to autozone and have them check your battery.

3 weeks seems odd to me for a stock battery not starting, though not totally impossible. However, usually once they go due to sitting a bit (as opposed to running the battery down with a radio or other device) usually tough to get it going.

Check the tightness of your terminals. If they are a bit loose even after you tighten them, replace the terminal(s). Your battery may not be charging fully via the alternator if terminals are not tight. I experienced this before and my positive battery terminal was the reason for my dead batteries in the past. Had it replaced for 10 bucks at Pepboys.

Got the battery back and autozone said it's good. Got the terminal tightened and the car started. I'll contact the dealer if my battery is still under warranty tomorrow.

Autozone can definitely check this for you, as well as SEARS and any automotive service center.
As a note, PLEASE DO NOT remove the negative or positive cable to the battery while the engine is running, This is dangerous, and can really damage your charging system even if the alternator wasn't originally bad.
The battery puts a LOAD on the alternator causing it to charge at the rate it needs to recharge the battery. If you remove the cable, the alternator senses no load or voltage, and the voltage regulator will apply maximum field to the alternator in an attempt to charge the battery. An unregulated good alternator can supply in excess of 17-20 volts DC, (which is enough to fry your engine management computer, stereo or anything else connected at the time. this is reeally bad especially if you are revving the engine while someone else removes the cable.
I speak from experience...please don't do it that way.

Marco,
The original battery and alternator are part of your comprehensive warranty, which is 48 months or 50,000 miles from the date of first use. According to your vin, the DOFU is 7/10/04 which is well within warranty.

MVALLIDO,
San Diego is my stomping grounds as well, and I like Bob Baker Lexus better than the OTHER dealership in town.
I DO get most of my parts from Carson Toyota just up the rad in Carson. My youngest daughter lives in Long Beach so she picks up my parts when I need them.
PM me if you want to talk offline or get together around town.
Thanks again
