Hi guys,

I would like to know if this is normal or if I need to get my 4WD checked.

I read in another thread that if it's in 4WD-HI, I can stay on it forever whether paved or if it's snowing.

Question is, when I'm in 4HI and it's already been fully engaged (4 green lights, not blinking), I will come to a stoplight and sometimes it takes like 5 secs before I can accelerate or get moving when I press on the pedal.
This happened to me a couple times now when trying to just go straight, sometimes when pulling out/turning. IT IS VERY DANGEROUS because I almost died when trying to pull out of a lot to get into the main road simply because my car would not move when I needed to. (Happened in multiple situations: dry pavement so there should be no slip, light rain, heavy snow)

I do not have the center diff locked (VSC off) because it's not fully snowing yet and the pavement is still dry. I read in another thread that you should only turn off VSC when you're not on dry pavement. I haven't tested turning VSC off in heavy snow yet to see if the same behavior will occur but this definitely shouldn't happen if I'm in just dry pavement correct?

VSC off means you have the center diff locked
