Surging during light to moderate acceleration

I and others are having a surging/pulsing on light acceleration in my 2021 Rav4. Feels like a bucking sometimes. Give it harder throttle it goes away. Dealer was worthless-said it's normal. No codes. Maybe related.

 

Might be, though I think this might've been more prominent on 2nd tundra fuel pumps and/or flex fuel models.

On my search, those symptoms seem to be a common enough occurrence across the board but for different reasons depending on the truck's gen.

Looks like there's a TSB out for 3rd Gen trucks now with similar (not identical though) issues that I believe may be more related to what you're seeing in your Rav than I experience with my tunny.

 

Interesting. Would you know what that TSB number for the 3rd gen is?
