I own a stock GS300 2007 RWD doing about 80K miles here in Thailand. Im facing one critical issue with my ride. While driving normally if I hit the brake hard the car seems to loose power then there is a hard knock from the rear which knocks the car forward. I think it is caused from the downshift of the gear, but im not quite sure. It happens often in the same kind of situation.
Have anyone every heard of this issue? Any advices would be appreciated
