It’s supposed to be cooler temperatures the next few days.
I have not taken it to the dealer yet, been too busy with other things. Hopefully if enough of us complain, Lexus will come out with a fix for it. If anyone does find a fix, please post it.

95% sure it will be a software fix.

Thats why the dealership can't find anything wrong or fix the problem.

The solution will have to come from Lexus.

Even the best diagnostic shop can't or wont rewrite the software, only Lexus.

I agree but I guess they haven't heard from enough people to realize it is a problem or to come up with a fix for it. If you live in a cooler location my would never see the problem but for those of us who live where it is normally over 90 degrees it is a big problem.

Ask to go out with them to demonstrate the issue. If they won't, escalate to the regional manager. Call corporate to get the attention and they track the issues. It's tedious but may be the only way to get results.

I had the *exact* same thing happen to me in my 2021 ES300h (bought new, less than 10k miles at the time) happen on an unprotected left turn, after the car was sitting. Left turn signal on, traffic clear, I begin to pull out, car creeps forward as I let off the brake, then i step on the gas pedal and nothing. My head lurches forward as I anticipate acceleration but the car doesn't respond at all. After 2-3 seconds (felt like forever) the car seems to "wake up." I posted about it a while ago when it happened.

It's almost as if the computer fell asleep, timed out, momentarily. It happened on one other occasion. I emailed my dealer about it asking for an appointment and they never responded (they had responded to other emails before). I sold the car and never determined what it is or had it fixed.
