A battery is never the same once it's been fully drained.

I researched on Reddit to find them (they are not the dealer who I bought from, as that dealer was atrociously bad), and with this dealer/SA at my 5K mile service they have been quite good.

I certainly hope you don't have to go through the torture of a buyback, regardless, its always good to keep a paper-trail, given Lexus and their dealers.

Not even with the mechanical key, and yes, I know about pulling out that extra thing under the driver's side handle. I drove it the day before, the hybrid/traction battery was 50% and everything worked fine. I never leave anything on in the car and I even had turned off the headlight delay so it does not stay on for 30 sec and waste battery charge. We were completely locked out. We had two locksmiths come out and the AAA (all of them called by Lexus Roadside Assistance). Nobody could get in. One of the AAA guys wanted to put some kind of bladder between the doors and then blow it up until there was a gap they could stick a hanger or something through so they could scratch my the new leather. I would not let him. How can that not bend the metal in the car anyway?? I kept calling Lexus but they really were not helpful. They agreed it needed to be towed but AAA has a policy that they will not tow cars from inside a garage. I called Lexus back to tell them they needed to send out a non-AAA tow truck but they kept sending out AAA. What a clusterfork. I called my salesperson but he never called back. I finally gave up. We went to bed last night not knowing what we were going to do. Oh, yeah, and of course the user's manual was locked in the car! Good thing I had already read through all 650 pages.

I awoke this morning and gave it another try. Could not get in with the FOB, the real key, or the app which I uninstalled and re-installed. I played around for a while with that little lever under the handle with the mechanical key inserted in the lock and FINALLY it opened! (maybe it was too tight before and needed loosening?) Well, clearly the battery was dead. Completely. Luckily my wife is thin and was able to crawl over the back seats (even the back seats are electric only) into the "trunk" and then use a screwdriver to pry open the lock cover on the hatch, unscrew another cover, and then finally push another lever using a screwdriver to get the trunk open so we could access the battery. I called AAA and they came out and said that the battery is dead and I need a new one. So WTF?? The car is a week old! Nothing was left on.

The first time I called Lexus and they requested a tow truck. When that arrived, the car was suddenly working again. I opted to drive it to the dealer to have it checked out. It was due for the first complimentary service anyway. They did not find anything wrong. Then today it happened again. This time we left the car sitting for 4 hours and it was still not working. So I decided to do some research and found this thread. Based on what I read here, we jumped the battery and got the car started. I hope that Lexus is paying attention and doing something about this. I got my car on November 1, 2024, so I have had it just over 9 months. That is still WAAAY too soon for a battery to go bad. On Monday I will call the dealer and see what they have to say.
Thanks to everyone here for the great research!! I will be disabling the digital key which I never use anyway.
