04 Navara dual cab rear window shattering

Hi Guys,
Three weeks ago a very good mate rings me with this unbelievable story.
He's sitting in his 04 Navara (Warranty runs out in March) on a wet day waiting for his wife to come out of a shop, when he hears a crack noise like a gun shot. He gets out and looks around for kids throwing rocks. Sits back in his Cab, Misses comes out and asks what happen the rear window. The only thing keeping together is the Tint. The tints about 9 months old. and it is installed by a certified Nissan tinter to cover warranty.
Anyway he goes to the local Windscrenseen obrien's, who tells him its a common problem with the rear demister. So he goes to the local Nissan Dealer who argues it not covered under warranty. He produces the warranty documents and is told it's not covered. My mate tells the local Nissan dealer he's not happy about having his 6 month and 3 year old in the car when it happened, and he's told he is lucky that it was tinted other wize it would of bleep tered all over them.

He goes back to the tinter and he's not a happy camper to say the lest about his work being blamed for the bleep tering. Especially when Nissan send him the cars from new to be tinted.

I'm just wondering if this has happened to anybody else and what has Nissan done about.
My Mate claimed it on his car insurance. And it is fixed nowI told him to get his car insurer to chase Nissan for it since it is a design fault.

Any thoughts would be very appreciated.

Cheers,

Hairs
