I cracked my rear taillight assembly. Only the glass is cracked, no other problems. Nissan indicates must replace entire assembly. Anyone know if can just replace the plastic portion?

 

I believe it is the entire unit.

 

Entire unit. Check out Ebay and you might get lucky.

 

You cannot buy the lense separately. Need to buy the whole thing, which for your car is probably expensive.
how bad did you crack it? which side? I have a pair with small cracks in the edge, not enough to let water in.

 

cracked enough to worry about water.
