There is nothing wrong in your car. However if you want peace of mind then get all oils changed including CVT .
You can get good after markets from reputable shop in your city. Also megamotorsport ( if I remember corrwcrly) is website which sells quality parts.
You can contact tracking world fir software update. Ir replace unit with 2021 model unit.
Brake hold feature is with gear for short duration on stops. For longer duration, better to use it without gear.
Don't use engine bay or fender cover as it generates massive heat
Just enjoy
