This is what happened...

After not driving the car for 3 cold days, the battery seemed dead...so i jump started the car with another car...and the car started, but started showing a bunch of warning lights...
It says, check vsc, brake malfunction, check brakes, check abs...

So i ignored all the warning lights and decided to drive the car on the highway for 30 minutes to fully recharge the battery...

After driving for 30 minutes with all the warning lights on, i parked the car and turned if off.

Then i tried to restart it again after 5 minutes...and it won't start...

Could it be that it didnt charge the battery because of all the warning lights were on?
Is the battery bad?

The battery is dated February 2012...and it says 84 months warranty...so will i get a free battery?

After all this, i disconnected the negative battery cable for 24 hrs hoping to reset it.

I jumped started car again...but it didn't reset, still got all warning lights...

Now turned the car off...and it's dead again...

So what do you guys think is wrong???

What is the cheapest solution...will Lexus give me a free battery?

Please HELP!!!

 

Check your battery and alternator. you can bring your battery to AutoZone etc. They can test it for you. Make sure your battery connections are good. sometimes they are loose or some corrosion on the battery terminals.

Most likely its the battery if you are able to jump start and drive around for 30 mins.

 

if i get new battery from autozone and they install it...will my warning lights go away or do i still need to make a trip to Lexus to get the warning lights reset

 

You don't need to get a new battery. AutoZone or similars stores can test your current battery. If they suggest you that you need to change it then get a new one under warranty.
Also they can check OBDII codes for free.

I can't tell if the codes will go away or not. You need to diagnose first.

 

Decided to goto Lexus since I had warranty left on the battery.
They prorated it 50%.
They installed the battery and reset the warning lights and also washed the car...all for $135.
Happy Satisfied Lexus Customer!!!

 

So all you needed was another battery then I assume?

 

Thats what i thought. he was able to drive around after a jump start. I guess if alternator was bad jumped battery won't keep the car running for that long.

 

$135? Pretty steep.

That car wash should've been a detail for that price.

 

^^^^And remember that's with a 50% proration
