Do you have any sound system in your car?

 

check it out. Hope it help you

 

Thanks, I watched the video I will go find a multi meter to test with, when I went to Lexus they did a drain test they said the amps were normal would that be the same thing or this is different, sorry kinda a noob lol

 

jus an update, id like to thank everyone who helped, my batt went dead again so i took it back to the dealership they kept it overnight, basically did exactly what the video above said ( checked all fuses to identify drain ) they found it was coming from the alternator ( i didnt know the alternator could drain battery but ...), so i have had it replaced, i will update this thread if the problem comes back again

thanks again to all those who commented your input was appreiciated

 

My Lexus 250 IS has the problem starting the car in the morning, the battery seems drained, and I need to reset the reverse camera setting each morning. The battery was replace in Novemer 2013. I have taken the car to have the battery tested, no fault was found with the battery, however the car had a 1 Amp leakage with all system turned off. I was told is could by the tracking system. The tracking company replaced the tracking system, as it was older than 5 years, and these satellite tracking system can cause problems after 5 years. This still has not solved my problem. If the car stands for 2 days I need to jump start it. I had had the computer plug into the car to test it. It was testing with the ignition on and with the engine running. No fault found.

 

Try watch the video above, if you can do it you might get your answer, when I took my car to Lexus they did the exact same thing
