Hey guys, last night I was on my way home but decided to stop at the gas station to refill my gas. Turned the car on and it wouldn't and we tried to jump it and it as well.I keep hearing a humming noise. At first, the car would turn on for 1-2 seconds and dies. Later on, it doesn't turn on at all but instead it tries to with a constant sound of how you turn your keys to the ignition and then dies.

I haven't tried a new battery, was thinking its the fuel pump.

Looks like it was the battery, I have a 84-Month Lexus Battery, has a purple sticker that say 7/14. Will I get charged or a free placement from my local Lexus Dealership?

battery warranties are pro-rated, meaning that you will pay a portion of the new battery's price depending on how long you have had the battery.

The sticker saying 7/14 is the start of the warranty - when you got it. That was 25 months ago. 25 months is roughly 30% of the 84 month warranty, so you will have to pay for 30% of the new battery.

So we jumped the car this morning and it was working until driving back the car dies going back home. I hear a humming noise must be the fuel pump (does the battery being low make the humming noise?). I get a PCode P0087. We are going to get a new battery to check it out.

If the car drives after you jump start it means your alternator is toast or on its way out. If you manage to get it on again test the charge at the battery terminals and it should read between 13-14volts with the engine running.

The battery test failed so they gave us a new one, but it still doesn't crank. We're towing it to the Dealership to let them see what's going on.

It sounds as if your starter was showing signs of failing and now it's completely dead if you don't hear the cranking noise. Have someone try to start the car while you use the tire iron to slightly bang on the starter and see if it turns over. If it starts using this method then it's the starter.

Hopefully you are able to resolve this.

Thanks for the respond, would a starter give me the code P0087 and a humming noise?
