Have the car for 7 months and twice after starting the car and releasing the handbrake, the car does not want to move after i start to accelerate. My driver washes my car 5 days a week and this has happen whenever after he washes the car, i don't drive it for a day, the car cannot move. Apparently it has happen to another car before my dealer claims. I have steel brakes. In some cases. the car starts to drive off only after a sound is heard from the brakes and it feels as if the brake does not want to let go. Anyone here experience this. My dealer does not have an answer and has informed McLaren. During this last experience, the dealer sand the disc brakes. They ask me to drive the car after it's wash. That's ridiculous. Besides this problem, i am happy with the car.
