Agreed! But as @mehran has rightly said, this seems to be some manufacturing fault and must be covered under warranty.
I still remember when I bought FAW V2 last year, both of its wiper blades were extremely hard and the rubber starting making scratches on wind glass. I took it to dealership, first they did not accept the fault on part of Al-Haj FAW and said that it is not covered in warranty, they will be replaced and the cost will be borne by me.
But when I pressed them hard, they agreed and replaced wiper blades at no cost to me.
I was like, k iss mein mera kya qasuur hai agar ye blades factory hi sey aesay aye hain?
