I just wanted to share my ongoing experience:
I took my 2014 IS250 F Sport with BSM into the Dealership in SoCal and they told me they narrowed down the battery drain to the Network Gateway ECU.
Since I have 65K miles, the dealer told me this part is not covered under my 50k Bumper to Bumper Warranty. They quoted me $8XX (Part + Labor).
With the help of this AWESOME forum, it seems like this issue is happening to other owners. Seems like this NG ECU is a defect and should be recalled. I contacted Lexus Customer Satisfaction and started a case with them and was told that a case manager will reach out to me within 2 business days. Updates will come as soon as I find out more information.
*OEM battery was replaced w/ a Lexus Battery 1-2 months ago directly from the dealership. Since the replacement, the car died four times.

It will show that the issue did occur during the warranty period, whether the dealer could verify it or not...or a repair attempt was made or not.

I think you have a strong case for a Goodwill repair. If by chance you had any documented proof of the battery dying before the warranty ran out, I would present that as well.

I ended up contacting Lexus Customer Satisfaction and explained my situation. A case manager was assigned to handle my case. It took two business days to reach out to me to follow-up and then another two business days until a decision was made. Lexus response, "Lexus has agreed to offer a one time goodwill to cover the full cost of your repair for the battery discharge issue..."
Now I am patiently waiting for the repair and expecting to receive my car back tomorrow!

so here's my experience so far:
first experienced symptoms last year. Jump started car myself, took car to Cherry Hill Lexus, and they replaced ECU it without making any fuss in springish 2015.
Since then, it seems like the part they replaced it with was superceded by another TSB sometime in summer 2016.
been traveling lots this year. car wasn't started for a month back in april. wife says its dead as a door nail. had lexus roadside assistance at thompson come jump it, take it in to see if they can replace the ECU again under the new TSB part number. They say nothing is wrong with the car and give it back to me.
this week I'm on travel again, car didnt start after 7 days. thompson lexus is came over to jump the car. i'm going to schedule an appointment with the original dealer who replaced my ecu without an issue. unfortunately that won't be for another 3-4 weeks till i get home.

Finally resolved... hopefully. Did the concierge service w/ the dealership where they came to the house, picked up the car and left a loaner. They said that the car's battery was shot and initially wanted $199 for a replacement. Wife kindly reminded them that we took the vehicle in three times for the failed ECU and after the third time they claimed battery was OK. Battery probably experienced severe drain cycles which eventually wore out the battery. They agreed to replace the battery free of charge under warranty and left it over the weekend to verify ECU wouldn't drain. Got it back two days ago. Still very happy with the dealership overall... kind of pissed they initially wanted to charge for the battery but I'm going to assume the service rep didnt bother to look at the car's service history and see that it was related to a warranty issue.

Car sat in the garage for over a week during the holidays. It was dead when I tried starting it this morning. I had it jumped and headed straight to the dealership with a print-out of TSB L-SB-0035-16 in hand. They will replace the Network Gateway ECU free of charge and I should be able to pick up the car at the end of the day.

I was also able to duplicate the issue. If I lock the car using the remote over night the car will die the next morning. Normally, I lock the car using the handle. My car is garage kept and the key is one floor up from the garage. Concrete floor! But apparently the range is enough for the car to be talking to the remote. Either that or the car is stupid and kept pinging the remote. Who knows. But locking using the remote will drain the battery. It’s too bad it took almost 4 years to finally be able to consistently repeat it.
