Remote Start - low battery?
For the last month or so when I have tried to use ERA (Enform Remote App) to start my car I get this error:
However everything with the battery checks out fine. Thoughts?

No, I drive it every day. I’ll get this when I try to start it leaving work for lunch or at the end of the day. 😩

Yeah that's early for the car battery to fail, especially in Tennessee, but I guess if you use it everyday, it's possible. Does it struggle to start when you do it from inside the car? I'd get the battery checked again at another place like autozone/advance auto(they do it for free).

Was the battery tested or did you just start your car normally? If it has not been tested and you have access to a multimeter, put it across the terminals and see what the voltage is reading. That can be the only thing the ECU is looking at when it is giving you that message (assuming your car is starting when you get in it). I don't know what the cutoff is to get that error, but anything under 12V could be cause. Do you have anything aftermarket that would cause a engine-off drain? My Mother found her 2 year old Avalon dead at the airport after a week in Kentucky and the OEM battery failed.

I may hold out til my next service and have it checked out. As much as I enjoy the remote start feature, it is clunky to use. my '13 Yukon has a better interface.
side note: I don't lock it at night in the garage and every so often I get the alert in the app that the car has triggered a "status event" or whatever. It has enough juice to lock/unlock the doors and retrieve vehicle status but that's it.

I just had my battery replaced for a very similar reason. My Enform remote start (also my key fob) would power the car up, but fail to start when the starter engaged.
But the error code I got was different (it was something like THV200).
The dealer tested it and replaced the original battery with a new one. The original battery was a Panasonic. Even if your battery tests OK, you should get the dealer to test it under the same load conditions that a remote start would have. The start up sequence is different when you use remote start.
I have a 2016 GS 350 with 36,000 miles. The battery replacement was covered by my original warranty.

I am at 44k miles, so if it is an issue with the battery then hopefully warranty covers it.

Hello,
I have the same issue with the OP. My car is 2015. The battery was replaced new by Lexus on 07/2017. I started having issue with remote start the car via key fob and Lexus Enform last Spring. The issue went away when the weather get warmer. I live upstate NY, so it is cold. The problem raised again last October, when weather dropped below 40 degree. Here are the thing I did to test the issue:
I have to bite the bullet and pay $60 for them to do the maintenance if I want to fight this issue. I can take the car home to do the maintenance myself, but I can't complain if the remote starter won't work again.
I think the issue is the amperage needed for Enform to start the car is somewhere between the battery amperage when warm and cold. The amperage needed to start the car via push button is much lower. I never have problem start it using push button, even after parked for couple of days in the cold.

- start the car using key fob and Enform app after the car is warmed up. Car started no problem
- repeat step #1 with key fob sitting in freezer for more than an hour. Car started no problem
- start the car using key fob and Enform app when the car is cold, like park for at least couple hours in cold weather. Car not started
- brought the car to Auto Zone. They said battery is good.
- brought the car to Lexus dealer last October. They said battery is good.
- bringing the car back to Lexus dealer. It is being service as we speak.

I don't think temperature is a factor in my case...it started in late summer when it was still very warm here in middle TN. I would try to start it ti cool before I left work in the afternoons, but gave up. Fortunately the GS climate controls adjust very quickly and before I am even 3 mins down the road it is tolerable inside the cabin. My tinted windows and sunshade help as well.

I had the exact same issue with my 15 GS. In addition, when I tried the remote start with my key fob I would get a mechanical click but no start. Dealer wanted to just replace the battery and be done with it. I had to explain to them that despite the warning, the battery was not the issue. They tested the battery and agreed. After a bit of coaxing they had their "technology expert" take a look at it. He said that he surfed some "internal" Lexus service tech forum sites and found that he needed to update ENFORM Transceiver. Either way once he did that it worked. This is what he wrote in my service history. PS, still have the original battery in the car without issue.Hope it helps
