Hi all,

I have a 2005 Lexus ES330. Recently it is exhibiting some problems related to lights, and consequently battery drainage. During the lockdown state, my car was resting in the parking lot. Yesterday, I found that the battery is dead and I had to jump start the car. Then today I drove the car a little to make sure the battery is okay. As far I can remember, before getting out of the car I turned everything off properly but at night I found that all of the car's lights are on. As a result, I again found that the battery is dead. I am not sure, it is an electrical problem or anything else. it is not possible everyday to jump start the car or oversee if the lights are turned on. Has it occurred to anybody ever? Would be really thankful if someone can suggest the probable causes. Thanks in advance.

 

Which lights? Headlights? Do you have the headlight switch set to auto?
