I bought a new 2022 Toyota 4Runner TRD Offroad premium Last year from a Toyota dealership. The vehicle now has 9500 miles on it. Since I have owned it, the vehicle has produced a burning sulfer smell while under heavier accelerations. I tend to only smell this oder when the windows are down. I have brought it in to the dealership and they claimed "they could not replicate the smell". I even took it to my local garage guy and he said he did smell some sulfer but was unable to locate the source. Any ideas as to what could cause this on a brand new vehicle (and a toyota at that). On a side note i took special care to properly break in the engine and had the oil and filter change prior to 5k miles.

Typically one of two things.. the smell is either coming from your battery or your engine is running too rich. You mentioned heavy acceleration... Excessive gas fumes are coming out of the exhaust manifold and heading down the exhaust into your catalytic converter. The dealer is full of crap, they know this isn't right.
Btw, you might try buying gas from a different store if you typically use mainly one place. Odd as it sounds, I've seen this remedy this issue because some gas stations have a higher sulfur content in their fuel than others.
Thanks for the input, but as far as the gas goes I generally vary where I get it from each week.
