Agree with Urlik, this is much more like a dead pedal…step on the gas and there’s a second or two delay before the car goes, very unnerving (again, only happens from a dead stop). It goes in for 6 month service later this month, I’ll tell the dealer but am not expecting much, my guess is it’s a factory tuning issue. Seems to have gotten worse with the hot weather (mid to high 90s and high humidity).

Do the symptoms change if another driving mode is selected? (EG, SPORT)
That might point to an issue with the throttle position sensor. (Which should be covered under warranty of course) <-- I'm good at W.A.G.s
It's always nice to provide as much info as you can. Even if SPORT throttle response doesn't affect anything....

Probably worth trying to get it on video at some point to show the service techs.

We have the same issue, it's horrible. Ours is a premium+ AWD. It's about 1-2 second delay and the pedal is just dead. It only happens when leaving a complete stop. We are due for the 5000 maintenance and will take it in. I think it is related to how the engine shuts down at stops, just my guess.

I ran some tests today - Luxury+AWD+AutoStart=off - jumps right off the line. Only 600 miles however.
Are you sure you aren't touching the brake pedal with your left foot when you go to get on the gas? Some people drive with two feet. Even the slightest contact with that brake pedal is going to thwart the accelerator.

Nice point. If you are one foot driving the engine restarts when you release the brake so it is running when you hit the accelerator. That could be an issue for some as well as hitting both pedals at once.

My last truck did the same thing (2021 Ram 1500 Ecodiesel), learned to just wait for a large gap in traffic before pulling out so I didn’t get t-boned…I traded it in for a 2023 GX460 with a Pedal Commander added, immediate throttle response!

Instructor
Try disconnecting the battery for 5 minutes to reset ecu before going to dealer as if that works that is all they will do until software update. Could be a hardware issue if that doesn't work.

The Highlanders are having the same issue. Apparently there was a manufacturing adjustment in late February that solves this problem. Is your RX made in March or later and still having this issue?

Ours was built in January, so maybe a software flash by the dealer will take care of the issue,
