This sucks and it's incredibly disappointing, wife has a 2014 garage kept and uses it everyday except Sat- Sunday's. Two years old now and this morning for the third time dead battery. BS LEXUS! Major fail.....service it's on it's way

 

Have you had your Gateway ECU replaced yet? This fixed my problem and has been discussed heavily on the forum.

 

I'm glad you mentioned this, I'll tell him now

 

I kept having the same problem and i thought it was because of my air, even when i removed my air it kept dying but lexus ended changing it for free

 

Gateway ecu? Is there a tsb? Where is the thread and how does it relate to the battery?

 

I don't believe there is a TSB, however my dealer knew the issue and took care of it with no queations asked.

Enjoy the read. The gateway discussion is tot wards the end of the thread.

Well he changed it no question but ask me to please get it check out

 

Question here,

Is it bad to not start the car for a while? Its been about 2 week, I left my car back at home. Since I moved back to my school. (gonna drive it back to school this weekend)

 

If everything is working properly in your car then there should be no issue with leaving your car sit for a couple/few weeks. This battery drain issue was completely random. Sometimes people complained of it happening after sitting for a few days, others it happened to them after running out to the gas station.

 

Ohh okay. My car is still pretty new. I was afraid of not starting it for a couple weeks would drain the battery..
