Hill Assist is freakin' CRAP, at least it is on a manual camaro.
Twice 4 times now on the same small hill, this ridiculous feature kicks in, and 4 times now I've stalled it, BUT - it gets worse.
When trying to move forward the car stays completely still - it feels like I'm pressing up against a brick wall or something. Then when it finally lets go it stalls AND emits a bad burning smell. It's not an oil smell, and its definitely not something that I think was caused by friction, but who knows.
GM : HILL ASSIST IS A DUMB IDEA that should be at least be able to disable it via MyLink or some other simple way instead of having to hack it.
