Cracks in rear light plastic - internal

[Alex1985]

Yes, mine is cracking, small thin cracks that we used to call crazing. The dealer said it was accident damage which I refused to accept. He photographed it said that he we submit it to MG. I wait for an answer.

Mine's a 23 plate - sent images to the dealer today and see what they say.
It's definitely stress cracking and looks like it's propagating from the bond of the inner and outer sections to me.
