I haven't read through this entire thread but I figured I would give my input with my IS350:
2014 IS350F RWD
Purchased 06/2014
Secondary vehicle (4,000 miles total)
Extended period of sitting in garage (1-3 weeks)
No battery issues since new, even in our very cold winter it was fine. No physical evidence of drained battery thus far. However, I do have a BT ODB-II sensor now, and it will read 11.6-11.8v when off, and I believe 13.8-14.2v when on (can't remember exactly the running value). Knock on wood, hopefully I wont have any issues moving forward either

My battery just died on my 2014 IS 350 AWD (October 2013 delivery). Has about 17,800 miles on it, and I just took it in for the 15,000 mile service a month ago, where the CCA checked out normal.
I had left it in the garage for about 36 hours, and now it will not start. At the end of March/beginning of April, I was out of town for a week, but I didn't notice problems after coming back. Today all the lights are off in the car, including the security LED.
Will be calling Lexus Roadside Assistance...

As an update, Lexus sent AAA to come along and jump the car. Everything appears to be working fine now. Hopefully, that's the end of it, but I've purchased a portable jump starter to leave in the car just in case.
If it happens again, I'll probably get it towed to the dealer for them to examine it. Maybe by then a definitive fix will be confirmed.

Just had my car die again on Friday evening. Towed it there Saturday morning. It is now Tuesday 4PM and they haven't been able to tell me what is wrong. They didn't call me Monday and I had to call them on Tuesday. They wouldn't give me a loaner Saturday because "they cannot authorize rentals when my car is not being worked on".
The service advisor also said "it may not be covered" as my car was purchased used. I've bought ex-rental vehicles that have full factory warranty after. I am going to let them get to the bottom of this and write to corporate as they made me feel like I was a 2nd class citizen for buying a $40k car USED. If its got factory warranty, I should have warranty (as long as its all stock which it is).
Been without my car for almost 3 days. I can't say I've had a good experience at all with my first and probably last Lexus.

I got my car back. What is strange is "we don't want to make you wait for your invoice" so the service advisor said she will email me. That was 6PM last night when I picked up the car. Still no invoice. Seems like something shaddy is going on.

You mean Don Valley Lexus? LOL Yes. It was them. I will be writing to Lexus head office to let them know my experience. How did you know? You've dealt with them as well?

Go to the one down the road on Leslie. They have a history with a fix for the battery drain issue, they replace a control module that seems to take care of things. It is buried somewhere in this thread or another one discussing this issue.

I think you had the same issue as well? The thing is I am at the East end of Markham so Lexus on The Park is kinda out of the way.....I would expect that all Lexuses are the same but appearently not. They've changed the battery and my car is warranted until Sept 2017 so the next time this happens, I know where to take it.
With that dealership, I think it is because they are in an area where there is alot of volume so customer service is kinda out the window. As I am typing this, I remember the first person I spoke with at Lexus was " Did you make an appointment?" after their colleague told them "there is a new tow in". DOH. Ya, I made an appointment for my car not to start. Genius.

Sorry I'm too lazy to read through the entire thread, but is this an F Sport issue? I feel like the LCD display and mechanic components of the tach kill the battery.
As I said in the prices paid thread, I went to check out a brand new F Sport and the battery was dead, the salesmen claimed it was due to people leaving on the lights which is complete BS.

Please do. I upgraded to aftermarket battery over a year and no issues. Why can't lexus owners do the same. People on this forum are very stubborn and just continue to whin about an issue that's been know since the 3rd generation IS rolled out. If you are waiting on lexus to admit they have a defective battery good luck. There's nothing wrong the ECU as some have suggested. Toyota knows their ECU and engineering better than anyone here or aftermarket tuners. Just pay for the darn aftermarket battery And save yourself the headache.
