Very straight forward, look the book and understand how it works, no issues with mine, you even have a delay when reversing up hill with the foot brake on hold then released.as mentioned above get someone to go through the operation with you,meet in with another owner to confirm car is also function correctly.
Getting rid of a car for something stupid is unnecessary the brake works fine in any configuration and operation, of course seatbelt on.
Took me a little while to get used to it but I have to say it's one of the best features on the car. That said, I've lost count of the number of times I've returned to my car to check that I've put it on !. Just my OCD !!.
I hate it! Lol! Most of the time it's okay but then some times it won't come off automatically and says I have to press brake! I'd have a normal handbrake back all day! But that's just my opinion! Plus no more hand brake turns in the snow! No fun!!!!!
I test drove the new golf with hill assist, and thought it was magic, didn't encounter any of the issues raised here, although I didn't try a reverse up the hill manoeuvre! However, the dealer put me in a facing down the hill situation, and worked great.
