2018 highlander transmission

Not sure about the burning but my ‘18 shuts the engine down instead of idling at lights and immediately powers back up as you take your foot away from the brake and prepare to push accelerator.

Burning may be new engine parts getting hot for the first time or times and for a lack of a better term, burning off the newness!

Took it to the dealer they showed me a button on the dash something to do with some enviremetal thing push button to off no problem the burning smell is gone thanks to everyone who pitched their advice

When using the autostart, is the engine suppose to shut off when opening the door? This is on a keyless 2018 Highlander. My husband's autostart on his truck does not shut off when door is open.
