I have contacted Pak Suzuki and put these issues before them. The Customer Service has sent a response to me today morning and have assured me of forwarding the complain to the concerned department for action. Let's hope something positive comes out of this.
Meanwhile, to build the impact, I encourage all GD owners to come forward and write individually to Pak Suzuki Customer Care at email@example.com about the problems you are facing with it. This way they will be alerted of the alarming nature of these issues.
I have already discouraged a group of guys in my office from buying it due to these problems. Should Suzuki fix these serious issues, GD's sale could gain momentum or it would die out otherwise.
