Burning smell from engine 2014 Camry

So recently, like last 2 days when i come home from work and park my
camry in my garage, i smell a faint burning smell, as if i slammed on the
breaks as hard as i could going 100mph. but there is no smell from the
breaks, or from the exhaust, and there is no smell in the cabin, but only
from the top vents of the hood. i dont know if this is bad or not, i don run my
car hard, usually max 3500 rpm because its a 4 cylinder.

its a 2014 camry with 22k miles on it, its well maintained, cleaned, and
taken care of like a baby. oil level is normal, but the smell is either burning
oil smell or burning plastic/breaks smell, not sure, after about 5 minutes of
the engine not running the smell is gone. Asked my dad who is the
mechanic he said there is no smell other than the bon fire from the
neighbors, but i know how wood smells like and i know how burning plastic
smells like, and its not burning wood.

the car is practically new, and has never had any problems at all. this
morning i went to my clinical and before i went inside, i opened the hood
and sniffed around, the smell is coming from the engine but its so faint that
it vented out within seconds of opening the hood, everything else smells
clean like simple green (cause i clean my car in insane detail).

any advise? should i be worried?
